What do you dislike about the product?
Until the specialized testing environment is completely provisioned, it takes up to 15 minutes for the containerized node orchestration engine to work. The external network perimeter scanning modules are unable to conduct a deep sub domain scan in very complex multi cloud network setups.
What problems is the product solving and how is that benefiting you?
Long wait times and shallow data coverage from manual red teaming consultants were problematic for our corporate security group. Every time code changes deploy to our production environment, NodeZero deploy full scope infrastructure attack campaigns.

Fantastic Potential, But Deployment is a Struggle
Reviewed on Jun 11, 2026
Review provided by G2
What do you like best about the product?
I like the automated aspect of NodeZero from Horizon3.ai, which I find awesome. Additionally, being able to test some of the vulnerabilities that our scanner picks up is great.
What do you dislike about the product?
Honestly, from a deployment standpoint, NodeZero is a dumpster fire. They specify to sell to MSPs but don't have a workflow that works for MSPs, at least not from what I've seen. The deployment is clunky. It requires a full Linux VM or a dedicated machine with no one-click deploy option. For a small team, this has been a nightmare for me. Because I don't have time to dedicate to deploying this in most cases. Especially since I'm just purely doing it as a light, agile deployment. It's just overall very, very clunky. It needs to be streamlined where they have a one-click deployment where I can launch a single EXE and that silently for my RMM and that deploys it. But it's just too much setup in my opinion.
What problems is the product solving and how is that benefiting you?
I use NodeZero from Horizon3.ai for proof of concept in penetration testing, and I find the automated testing of vulnerabilities it picks up awesome.

Continuous testing has improved security visibility and validates defenses across critical systems
Reviewed on Apr 27, 2026
Review from a verified AWS customer
What is our primary use case?
My main use cases for The NodeZero Platform by Horizon3.ai primarily focus on determining how secure our environment is. I always pitch to various customers that they need to understand how secure their environment is. Specifically, I help them assess how secure it would be if an attacker breaches into any of their critical systems such as domain controllers or systems with entire admin access.
I evaluate what lateral movements an attacker could carry out into other critical systems and critical servers in their environment, and how they could steal their crown jewels. It is essential to know all of this and see it in your environment so you can take up the necessary defense that is needed.
How has it helped my organization?
The NodeZero Platform by Horizon3.ai has impacted my company positively. Whenever we deploy anything new, either a server or a DNS server, we are able to easily conduct a quick test with The NodeZero Platform by Horizon3.ai to know how secure that server is from wherever it has been placed. This quick test has enabled us to have peace of mind knowing that we are able to identify either the security lapses that may be available or not, and we are able to get that information quickly, just with a few clicks of the button.
What is most valuable?
The features I appreciate most about The NodeZero Platform by Horizon3.ai are as follows. First, the ease of deployment is exceptional. The deployment is very easy, taking under ten minutes to complete. Second, the process of initiating a pentest is very well detailed and straightforward. A new graduate out of school can make use of this platform effectively. Third, the detailed reports are outstanding. The detailed reports make it easy for everyone involved. They have something for executives, the network team, and the vulnerability and threat team. The reports are all well detailed, so those are the three main reasons why I appreciate The NodeZero Platform by Horizon3.ai.
What needs improvement?
Improving The NodeZero Platform by Horizon3.ai should include having audit logs on the platform. For instance, if a user deletes a pentest from the platform, it would be beneficial if audit logs could show that a particular user deleted a pentest on a specific date and time. An audit log trail would be very valuable for the platform.
Second, it would be helpful to have a dashboard or feature that showcases the NodeZero runners and their download speed or whatever is being used. When you are using a runner to run a pentest, it would be beneficial to see the module logs and everything that is being run before the runner kicks off and shows up on the dashboard. If those two things could be added, it would significantly improve the platform.
