Automated pen tests have strengthened security and provide detailed monthly remediation insights

  • April 20, 2026
  • Review provided by PeerSpot

What is our primary use case?

I have been using The NodeZero Platform by Horizon3.ai for about three years now.

I use The NodeZero Platform by Horizon3.ai to run scheduled penetration tests against my internal and external network resources.

I recently changed my hosting service and web hosting service, and along with that change, I decided to run another penetration test against it to ensure everything was functioning properly. I did find a vulnerability which I was able to quickly address and resolve.

I run this once a month in general, although I will run it whenever something new is introduced into my infrastructure. My monthly run reports provide me with data that I can review, and if I find anything in there that I did not see before, I can address it.

What is most valuable?

One of my favorite features of The NodeZero Platform by Horizon3.ai is the scheduling feature, which means I do not have to remember to run the penetration tests. Another feature I really appreciate is the remediation tasks that it provides. When it offers remediation guidance, it gives me steps to resolve the issue, which saves me time in determining what I need to do to remediate a certain vulnerability.

The remediation steps provided by The NodeZero Platform by Horizon3.ai are usually quite detailed and helpful. Occasionally, I will get one that does not offer a lot in the way of specific steps because the device on which it found the vulnerability is not a standard device that it recognizes. However, if it is a Windows box or Linux box, it is very good about giving me accurate information.

I believe that The NodeZero Platform by Horizon3.ai has kept me safer in a cybersecurity sense. It is one of a couple of different products I use for that purpose, but because I have cybersecurity insurance, I am required to run pen tests at least once a year. This product allows me the opportunity to run it as many times as I want, which is very beneficial because when new things are introduced into my network, I may not be able to identify these vulnerabilities until I run my next penetration test, which could be up to eleven months later.

Because I stay on top of these things, I am not usually caught off guard with a security issue that suddenly appears. I see them monthly and I do not have to generally perform any sort of emergency response that I would have had to do in the past when I had nothing in place.

What needs improvement?

I would love it if I could whitelist certain vulnerabilities that I consider not especially significant with The NodeZero Platform by Horizon3.ai. The NodeZero Platform by Horizon3.ai classifies them based on severity, and the severity for a lot of these things, such as threes, ones, and 0.01s, are generally things that I do not care too much about. I want to see them in a report when they appear the first time, but I would love it if I could simply check that one and indicate that I do not want to see a report about this one again because I am not going to take action on it.

For how long have I used the solution?

I have been working in this field for around thirty years.

What do I think about the stability of the solution?

The NodeZero Platform by Horizon3.ai is quite stable.

What do I think about the scalability of the solution?

It is kind of difficult for me to comment on The NodeZero Platform by Horizon3.ai's scalability because I have not had to change the scale. It certainly works fine in my rather small environment, but since I have not run it in a very large network environment, I cannot really say much more than that.

How are customer service and support?

Customer support for The NodeZero Platform by Horizon3.ai is awesome. I love the chat person I work with on chat. She is always super responsive and very patient and is able to get to the bottom of my problems, which are fairly infrequent. At the beginning, there were a few little hiccups that I was causing through some misunderstanding on my part, but she was very good.

Which solution did I use previously and why did I switch?

I previously used Fortelist, an annual service that they provided to run penetration tests on my network. The reason I switched is because I wanted to be able to run penetration tests more frequently, and it simply would not have been cost-effective to do it more often than one time a year. That is the main reason for the change.

How was the initial setup?

Interestingly enough, I have used that quite a bit in the past. The last time I ran my pen test, I for whatever reason was not able to quickly retest as conveniently as before. I am not really sure why that is, and I probably should just talk with Horizon3.ai about that.

Certainly, time has been saved with The NodeZero Platform by Horizon3.ai, and I would imagine money has been saved from the previous way of doing my pen tests, which were a yearly pen test that were quite expensive to do. There has been no change in employment or employees, but as far as the licensing costs, I think that was a big win for me.

What about the implementation team?

I did not have involvement in the evaluation process. I was not the one who evaluated it; I was the one who implemented it.

What was our ROI?

I believe The NodeZero Platform by Horizon3.ai has helped reduce my pen testing costs, but I cannot tell you exactly how much as I am not the person who paid for those services. However, I believe it was a significant reduction.

What's my experience with pricing, setup cost, and licensing?

I cannot really speak to the pricing as I was not involved in the purchase of it or any of the costs. I was the one that implemented it, and for that, I give it a thumbs up—it was awesome.

Which other solutions did I evaluate?

I think everything else is fine.

What other advice do I have?

The first time you run a test with The NodeZero Platform by Horizon3.ai, be prepared to triage because you are going to find things you had no idea you had.

It is because I have not had any serious problems for a long time. I would say that the very first time I ran The NodeZero Platform by Horizon3.ai, I did find many things such as open SFTP ports, open FTP ports, and open database ports that I was able to quickly address. I would say quickly, but it took a while because the platform found so many. However, it was super helpful because I did not have a single way to find those things before.

I give this review a rating of nine.

Automated penetration testing has reduced remediation time and provides clear attack evidence

  • March 26, 2026
  • Review provided by PeerSpot

What is our primary use case?

I use The NodeZero Platform by Horizon3.ai for internal and external pentest scans, and it also provides Kubernetes scanning and scanning of GitHub accounts. Primarily, I use it for internal and external pentest scans.

Regarding on-premises systems, I have executed pentest scans on externally located and internally located systems, but I have not tried much with on-premises servers. I honestly do not have significant exposure in that area and cannot provide feedback on that part at this time.

What is most valuable?

The best features of The NodeZero Platform by Horizon3.ai are that it does not require much effort compared to manual penetration testing. You simply configure the scan and modify the requirements you need, and it scans and provides quite good results. The platform presents the data in a very clear way that even non-technical people can understand the dashboard and read through it.

The user interface is significantly more user-friendly than other tools I have used. The data and evidence gathered from the penetration test scan is excellent. It shows any compromised accounts and devices, demonstrating exactly how The NodeZero Platform by Horizon3.ai executed the attack. This is considerably better than any other tools I have used.

The NodeZero Platform by Horizon3.ai incorporates technologies that go beyond traditional testing and scanning methods for vulnerabilities, such as Nessus, Qualys, and Rapid7. While those tools focus on finding vulnerabilities, The NodeZero Platform by Horizon3.ai not only finds the vulnerabilities but also attempts to exploit them, gathers available evidence, and provides possible ways to fix them. This is one of the greatest features of The NodeZero Platform by Horizon3.ai.

When we run the penetration test scans, The NodeZero Platform by Horizon3.ai definitely identifies all negative points and the external attack surface related to them, showing what those external attack surfaces are and how we could fix them.

What needs improvement?

I feel there could be improvements in scalability, although at this point I have no specific negative points to report.

For how long have I used the solution?

I have used the NodeZero Platform by Horizon3.ai for approximately eight or nine months.

How are customer service and support?

The customer support is fantastic. I personally reached out to them, and The NodeZero Platform by Horizon3.ai provides sufficient evidence needed to understand the attacks it attempted, gathering relevant information regarding compromised accounts.

Which solution did I use previously and why did I switch?

For automated scans, I have not used any other tools apart from manual scanning. I have been using The NodeZero Platform by Horizon3.ai for the first time, and it feels good and easy to work with.

What was our ROI?

I do not know exactly in terms of the client because I work for the client, but personally I feel the remediation time is significantly reduced compared to what we used to do with manual testing. I would estimate approximately thirty to forty percent reduction.

What's my experience with pricing, setup cost, and licensing?

The NodeZero Platform by Horizon3.ai is better than manual penetration test scans. Usually, manual penetration test scans take considerable time and money, but I believe The NodeZero Platform by Horizon3.ai is definitely worth trying if you are considering using it, because it reduces the time and cost associated with manual scans.

I do not have detailed knowledge about specific costs, but I definitely feel that investing in manual penetration test scans is much higher than the automated scans of The NodeZero Platform by Horizon3.ai. Although I have no idea about the exact cost difference, I definitely believe there is a significant difference in favor of The NodeZero Platform by Horizon3.ai in terms of lower cost.

What other advice do I have?

Regarding deployment, it is quite easy if you are talking about the cloud environment and configuring the scan. I do not find it too complex. The setup should be very quick, almost instantaneous, comparable to logging into any other portal.

The NodeZero Platform by Horizon3.ai offers options in both directions, but I personally used it in a cloud environment, and I feel it is much easier than an on-premises environment. It is easy to install, but it takes a little bit of time. Once you log in and share your targets, you can configure your scan and run it, making it much easier overall.

I would certainly recommend The NodeZero Platform by Horizon3.ai to others. I am sure they would appreciate how it presents the data and reports. It does not just provide a technical report; it presents multiple reports of various attacks that may be useful for management who might not understand technical terms. It definitely helps to have those kinds of reports as well, allowing anyone to understand what is happening in the environment and what can be done about it.

Based on my work experience over seven to eight months of using The NodeZero Platform by Horizon3.ai, I am still learning more about the product, and there is much more to explore. I would give this product a rating of eight out of ten.

Automated pentests have improved remediation priorities and now reveal real business impact

  • March 20, 2026
  • Review provided by PeerSpot

What is our primary use case?

The main use case for The NodeZero Platform by Horizon3.ai is internal network testing, as we put up a few runners in the customer environment and then we scan and test the environment.

How has it helped my organization?

The main benefits that The NodeZero Platform by Horizon3.ai brings to the table or how it helps to improve the way the organization functions is that it is very easy to read the pentest results from when it comes to prioritizing the fixing order of things, because now companies can actually see what the critical part is, how it affects the business, not just the system or one device, but the business impact is the question here, which is why companies take autonomous pentesting instead of a few manual pentests a year or vulnerability management.

What is most valuable?

The best features in The NodeZero Platform by Horizon3.ai are that it is a very easy environment to maintain, as we can pretty easily set up new pentests or add new assets there to be tested. We have a good connection with the actual company behind it, Horizon3.ai, so they help us whenever we ask pretty quickly.

My impression of The NodeZero Platform by Horizon3.ai's feature that allows security teams to fix and retest vulnerabilities instantly is that it is one of the core elements our customers use and it might even be the reason why they choose this tool over traditional vulnerability scanning. Of course, they get the pentest results on top of vulnerability scanning, but its crucial part is that they can test the especially critical findings and high-level findings immediately after they have fixed them.

The NodeZero Platform by Horizon3.ai has helped my clients reduce pentest costs, as for some companies, the cost has raised a bit, but they get a bigger area tested with just a slightly bigger price. A usual case is when they move from vulnerability scanning to pentesting, the price does not actually go up except maybe just slightly.

What needs improvement?

Apart from the licenses, specifically the tenant-based licenses that were mentioned, I would like to see more deep investigation of different environments in The NodeZero Platform by Horizon3.ai, especially in cloud. A proper mapping of assets and maybe some kind of map where I can actually see what devices or accounts are connected to each other would help a lot with the investigation and prioritization of things.

There are missing features in The NodeZero Platform by Horizon3.ai that I would like to see included in the next release or some functionality that I would like to see enhanced in it in the future, as they have already spoken of web application testing, so that is something I am looking forward to. API testing would be nice to see. I think it is coming right after the web application testing. However, the one thing that is very much asked from us as a service provider is DAST testing, so when a company is building a software, they could see their current security status while they are building the application.

For how long have I used the solution?

I have been working with The NodeZero Platform by Horizon3.ai for about two years now.

How are customer service and support?

I evaluate customer service and technical support for The NodeZero Platform by Horizon3.ai as good. If we have had problems, that is with the actual licensing style they are using. When we have customers, like midterm, let us say six months after our own contract starts, we get the pricing for the next six months, but then we have to negotiate again. What I would like to see from them is a tenant-based licensing for our customers also, not just us. Overall, we have good contacts, we get answers to questions we ask them very quickly. Support has been pretty quick also.

On a scale of one to ten, I would rate the tech support for The NodeZero Platform by Horizon3.ai as nine.

Which solution did I use previously and why did I switch?

Prior to adopting The NodeZero Platform by Horizon3.ai, I did not work with any other solution of the same kind, as mentioned, I have done manual pentesting. Burp Suite has some automatic scanning and testing extensions, but I have mostly been a manual tester and bug hunter. I have read a lot about Aikido solution or Pentera, but that is just on a common level of knowledge gathered from the internet, not anything too deep or technically deep.

What's my experience with pricing, setup cost, and licensing?

Regarding the pricing aspect of The NodeZero Platform by Horizon3.ai, my experience with the pricing, setup cost, and licensing part of it is that the setup cost was very minimal. I do not know if we even had that to be sure. The pricing is not on my responsibility, but what I have heard from our salespersons and the business executive whose responsibility it is, is that related to traditional vulnerability scanning, it is even cheap. The pricing is not the point why it would be hard to sell, so I guess it is on a good level now.

Which other solutions did I evaluate?

I did evaluate other options before going with The NodeZero Platform by Horizon3.ai, as I was not myself in the process of choosing between The NodeZero Platform by Horizon3.ai and others, but I know that we chose it because it is cloud-based, so it is easy to set up. There is no need for a customer to purchase on-prem servers or anything like that. They just need a little runner on some laptop or server or virtual machine, so it is easy to maintain. It is not too pricey for the customers we planned it for. Currently, it supports very well our offensive security offerings.

What other advice do I have?

With our customer, I review the results of The NodeZero Platform by Horizon3.ai and we see what they should do to improve their security maturity.

NodeZero's endpoint security effectiveness feature impacts the understanding of potential security threats, as I must say that I do not have so much results yet in that area. It is quite new to me and I am looking forward to having more testing on endpoints on both our own environment and customers. What I have seen so far, I would say currently is good, but I personally need to know more before I can say anything in any direction.

I assess The NodeZero Platform by Horizon3.ai's impact on the organization's remediation time as much better than in traditional vulnerability management because now they actually see what has been caused and what the business impact is. They actually have already a pretty prioritized list of what needs to be fixed first. The so-called false positive noise has been reduced to almost zero. It has affected that part very much.

The advice I would share regarding organizations considering The NodeZero Platform by Horizon3.ai is that, as mentioned earlier, if there is a company that should choose whether they go to pentesting or vulnerability management. Pentesting can be a very nice test, one which does not cause any issues or show to users anyway. They can also choose the stress test mode, which may even lock out accounts or crash a computer, but we can adapt and configure the test for any environment customer needs. As a technical implementation or technical tool, it is very straightforward to set it up and schedule the scans or tests and see the results. Of course, the results could be more; now it is just a list of assets pretty much and another list for findings. There could be some maps of what accounts and devices are connected to each other, which would help. Otherwise, the solution itself is very fine and I would recommend it as an MSP partner or as a user of the tool to pretty much any company. I rate The NodeZero Platform by Horizon3.ai a nine out of ten overall.

What is our primary use case?

The NodeZero Platform by Horizon3.ai is a pen testing tool specifically designed for endpoint pen testing.

In my organization, I manage The NodeZero Platform by Horizon3.ai as a service provider with plenty of clients, and I am the decision maker regarding the renewal of licenses and the extension of services, along with a couple of other teammates who assist with this.

I have deployed The NodeZero Platform by Horizon3.ai in two forms: for internal penetration testing, it requires deploying an agent into the internal network, while for external tests, it is a fully cloud-based tool.

What is most valuable?

The best feature of The NodeZero Platform by Horizon3.ai is that it is an autonomous pen testing tool that knows how to penetrate into the system automatically and perform lateral movement inside the network without the need for scripting.

Regarding The NodeZero Platform by Horizon3.ai's feature to fix and retest vulnerabilities, it provides reassessment capabilities. While it does not fix vulnerabilities instantly, it allows for reassessment as soon as vulnerabilities are fixed.

Regarding the endpoint security effectiveness feature, The NodeZero Platform by Horizon3.ai does not provide endpoint security but is an offensive tool designed to find weaknesses in endpoint solutions, not to protect them.

When assessing how much The NodeZero Platform by Horizon3.ai has helped reduce pen testing costs, it plays a vital role in providing value compared to manual methods, although it depends on the client's specific needs and budget.

What needs improvement?

I believe reporting for The NodeZero Platform by Horizon3.ai has room for improvement, specifically in terms of customizability for service providers and the challenge of dynamic IP white-listing, which I have provided feedback on.

For how long have I used the solution?

I have been using The NodeZero Platform by Horizon3.ai for more than three years.

What do I think about the stability of the solution?

When it comes to the stability of The NodeZero Platform by Horizon3.ai, I would rate it around seven to eight because the stability is not that high initially due to the need for daily updates and modifications as new vulnerabilities appear.

So far, we have three specialists who focus on The NodeZero Platform by Horizon3.ai.

How are customer service and support?

In terms of technical support for The NodeZero Platform by Horizon3.ai, I would rate it an eight, as they provide a business analyst for account handling and usually respond within a week.

How was the initial setup?

The deployment of The NodeZero Platform by Horizon3.ai is very easy.

Implementing The NodeZero Platform by Horizon3.ai takes hardly 10 to 15 minutes, as you only need to deploy it on one endpoint, which will handle pen testing for all systems.

What about the implementation team?

From our side, maintaining The NodeZero Platform by Horizon3.ai requires minimal effort as we just keep the license up to date, needing only the server on which it is deployed to run.

What's my experience with pricing, setup cost, and licensing?

The pricing of The NodeZero Platform by Horizon3.ai was better than others or at least comparative, shifting to an IP-based licensing model which I believe offers fair pricing.

I would say it is fairly priced.

Which other solutions did I evaluate?

In comparison to other vendors like AttackIQ and Pentera, The NodeZero Platform by Horizon3.ai stands out due to its autonomous capabilities that allow it to learn from the environment and follow different attack patterns, offering a better attack path workflow.

What other advice do I have?

My advice for implementing The NodeZero Platform by Horizon3.ai is to conduct a proof of concept first because it provides insights beyond what other vulnerability management tools detect. I gave this product a rating of 9.

Automated testing has transformed how we deliver fast, consistent security assessments

  • March 17, 2026
  • Review from a verified AWS customer

What is our primary use case?

The primary use case for the NodeZero platform by Horizon3.ai is to deliver penetration testing as a service to our clients, enabling us to support their security assurance, risk reduction, and compliance obligations.

What is most valuable?

The key capabilities of the NodeZero platform by Horizon3.ai that I have found most valuable are its speed, scalability, and consistency. It is able to cover a broad scope in a relatively short period of time, which delivers significant efficiency gains when compared with traditional manual testing. It also provides a more consistent outcome, as the process is not influenced by human bias or variability.

One of the most valuable features is the ability for security teams to remediate and retest vulnerabilities immediately. The one-click verification capability is particularly effective, as it allows fixes to be validated quickly without the need to rerun the entire assessment. This streamlines the remediation cycle and supports faster confirmation of security improvements.

The platform’s real attack capabilities have also helped reduce false positives in the identification of vulnerabilities across our on-premises systems. Because the findings are evidence-based and validated prior to reporting, the results are more reliable and actionable. This enables us to focus our efforts on confirmed security issues that genuinely require attention, rather than spending time investigating theoretical or unverified exposures.

The NodeZero platform also strengthens my understanding of potential security threats through its continuously updated capabilities. With new vulnerabilities emerging and being exploited in the wild on a regular basis, it is valuable to have a platform backed by a strong research and development function that continuously updates attack content to reflect the current threat landscape. This makes the platform effective not only as a point-in-time validation tool, but as part of an ongoing and continuous security assurance programme.

What needs improvement?

At present, the platform is relatively rigid in how it operates and offers limited flexibility to align with individual user preferences or organisational requirements. While this structured approach has advantages in maintaining consistency, it can also be restrictive in practice.

In particular, greater flexibility around reporting and risk scoring would add significant value. For example, the ability for users to adjust or contextualise vulnerability ratings based on their own environment, risk appetite, or compensating controls would make the reporting more adaptable and relevant to different use cases.

For how long have I used the solution?

I have been working with the NodeZero platform by Horizon3.ai for nearly a year, with hands-on experience using the platform since August of last year.

What do I think about the stability of the solution?

I would evaluate the NodeZero platform by Horizon3.ai as excellent in terms of stability and reliability. We have not experienced any issues with accessibility or availability, and the platform has consistently performed as expected.

I would rate the stability of the NodeZero platform by Horizon3.ai as 10 out of 10.

What do I think about the scalability of the solution?

I consider the NodeZero platform by Horizon3.ai to be highly scalable. It is well-suited to enterprise environments, straightforward to deploy, and can be implemented within minutes. Its speed and breadth of testing enable it to assess large areas of network coverage in a relatively short period of time.

I would rate the scalability of the NodeZero platform by Horizon3.ai as 10 out of 10.

How are customer service and support?

I interact with both the technical support and customer service teams at Horizon3.ai in relation to the NodeZero platform.

I have direct access to representatives in my region through a dedicated messaging channel, which makes communication quick and efficient. Whenever I need assistance, I can reach out directly and typically receive a response within an hour, and often sooner. In my experience, the team has been consistently responsive, helpful, and easy to work with.

I would rate the technical support for the NodeZero platform by Horizon3.ai as 9 out of 10, with 10 representing the highest level of support.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

Prior to using the NodeZero platform by Horizon3.ai, our security testing activities were conducted entirely through manual methods, as we had not previously utilised an automated platform of this nature.

How was the initial setup?

The installation process for the NodeZero platform by Horizon3.ai is straightforward and easy to complete. The deployment workflow is simple: you download the preconfigured virtual machine from the Horizon3.ai website, run it within the target environment, and then copy and execute the provided script within the locally deployed agent. Once that is done, the platform is ready to begin testing almost immediately.

In my experience, I have not encountered any challenges or blockers during installation. The overall setup process has been smooth, intuitive, and reliable.

What about the implementation team?

I participated in the initial setup and deployment process of The NodeZero Platform by Horizon3.ai.

What was our ROI?

So far, I have seen a clear return on investment from the NodeZero platform by Horizon3.ai. As an autonomous solution, it has enabled us to save a significant amount of time and effort by reducing the level of manual work required. This has been one of the key benefits of adopting a platform of this type.

In addition, because the platform is designed to scale effectively for enterprise environments, it has also helped us improve efficiency on larger engagements. As a result, we are seeing cost savings through reduced effort and a more streamlined delivery model.

Which other solutions did I evaluate?

Before selecting the NodeZero platform by Horizon3.ai, I evaluated several alternative solutions from other vendors, including Pentera and RidgeBot.

We ultimately chose NodeZero for three main reasons. First, its technical capabilities were better aligned with the specific use cases and outcomes we were looking to achieve. Second, it was more commercially competitive and offered better value than the other solutions we assessed. Third, the quality of both customer and technical support was a key differentiator. Whenever we required assistance, advice, or issue resolution, the Horizon3.ai team was responsive, accessible, and highly supportive in working through our requirements.

What other advice do I have?

As a managed security service provider, we use the NodeZero platform by Horizon3.ai in both a reseller and advisory capacity.

Its impact on remediation has been particularly positive. The platform provides a clear and efficient way to manage remediation through its dedicated vulnerability management capabilities, with the added benefit of integration into platforms such as Jira and ServiceNow. Because findings are evidence-based and validated, the output is highly actionable and carries a low false-positive rate, making it a strong remediation enablement tool.

From a commercial perspective, I am familiar with the platform’s pricing and licensing structure and consider it to be well-positioned across market segments. Its tiered pricing model makes it accessible for small and medium-sized businesses, while its enterprise packages provide the additional functionality required by larger organisations.

The platform has helped us reduce our penetration testing delivery costs, which was a key objective for us as a consultancy and service provider. Although I cannot disclose a specific percentage reduction, the cost savings have been significant.

My overall rating for the NodeZero platform by Horizon3.ai is eight out of ten.

Integrated security platform has unified monitoring and continuously finds critical vulnerabilities

  • Review provided by PeerSpot

What is our primary use case?

The use cases for The NodeZero Platform by Horizon3.ai include Attack Surface Monitoring primarily, followed by third-party risk management and Attack Surface Management, as well as social media monitoring. These are probably the three biggest use cases.

What is most valuable?

What I appreciate the most about The NodeZero Platform by Horizon3.ai is its distinctive competitive advantage, which is the ability to bundle multiple security solutions into one single tool. While there is competition, there is nothing quite like The NodeZero Platform by Horizon3.ai at the moment, at least to my knowledge. That is the biggest USP.

Otherwise, it is a question of time. If you benchmark a pure play Attack Surface Management tool alongside The NodeZero Platform by Horizon3.ai, then sometimes The NodeZero Platform by Horizon3.ai may do a better job, whereas sometimes the other tool might do a better job. It is a question of always catching up, much as the different AI models evolve. At some point, ChatGPT was super good, then suddenly it became Gemini and today it is flawed. Competition is constantly ongoing. However, the area where The NodeZero Platform by Horizon3.ai has done pretty well is to build multiple tools and stack them into one single solution, and that is something which competition has not really done. I have no answers to why, but that is the biggest thing with The NodeZero Platform by Horizon3.ai.

The feature that allows security teams to fix and retest vulnerabilities instantly is part of the Attack Surface Management functionality of The NodeZero Platform by Horizon3.ai. The whole idea of ASM is continuous monitoring of vulnerabilities, so the minute you actually fix it and you say that it is fixed, it will go back and check against the same particular use case. That is the functionality being discussed.

What needs improvement?

The downsides of The NodeZero Platform by Horizon3.ai are that it is an expensive tool; it is a very expensive tool.

Since The NodeZero Platform by Horizon3.ai is integrated, for people who are not looking for everything but just one particular functionality, compared to any other tool, The NodeZero Platform by Horizon3.ai tends to be a little more expensive.

For how long have I used the solution?

I have probably been working on it for a year.

What do I think about the stability of the solution?

In terms of stability, I have not seen any issues with The NodeZero Platform by Horizon3.ai; I have not experienced lagging, crashing, or downtime.

I do not know the underlying architecture of The NodeZero Platform by Horizon3.ai; it is a SaaS solution, and since it has not crashed ever, and it is not a business-critical application, it is not your ERP. So frankly, even if they did crash, it would be very hard to notice unless we really manage to try and use it at that time and we get caught. The whole idea of The NodeZero Platform by Horizon3.ai is to work in the shadows and just keep pushing alerts to you. You only log into the tool when you want to. The idea is it works behind the shadows; so even if there was a downtime of, for example, five minutes or ten minutes, it is not your ERP system and you will not really notice it.

Which solution did I use previously and why did I switch?

There is no single tool which can really say it has all the features that The NodeZero Platform by Horizon3.ai has. However, I have tried other tools which offer some parts of The NodeZero Platform by Horizon3.ai functionality. For example, I have used different third-party risk management tools, ASM tools such as SpyCompass, and IzoLogic for dark web monitoring and things of that nature, which are different tools, but they serve different areas; whereas The NodeZero Platform by Horizon3.ai is a combination of everything.

How was the initial setup?

The initial deployment of The NodeZero Platform by Horizon3.ai is absolutely straightforward and simple; all I need to do is request for an instance, specify these things, and there is nothing really to install apart from the agent server that I need to install. It is not a big deal.

What other advice do I have?

In terms of the platform's real attack capabilities, The NodeZero Platform by Horizon3.ai identifies vulnerabilities in my on-premises systems as good as any other vulnerability scanning solution that is out there. It does a very good job of finding real vulnerabilities and prioritizing them based on the criticality of the asset and contextualization of the organization's nature, which is very standard to any typical vulnerability scanning solution that is out there.

For The NodeZero Platform by Horizon3.ai overall, I would rate it an eight out of ten, with ten being the highest and one being the lowest.
