Device42 - Discovery & Dependency Mapping - Cloud & Hybrid IT

For asset discovery with Device42 , I monitor a few VMs, and for certificate management, I deal with applications that utilize TLS certificates. A recent situation that was particularly helpful was our renewal process which occurs every six months to a year where I ensure the certificates are up to date and monitor our virtual machines on the dashboard including both on-premises and cloud resources.

I use Device42 to integrate with our Jira  for our ticketing system, which is very helpful in providing alerts about our inventory's status, whether it is end of life or needs updates. It aids in certificate management by informing us through Jira , thus supporting our reporting processes and compliance efforts.

Device42's asset inventory feature helps our organization by making auditing easier as I can generate reports and automate dashboards for top management. I also plan to leverage features related to AI and artificial intelligence to integrate with change management systems like Jira or ServiceNow .

Device42 positively impacts our organization by providing dependency mapping for our devices, and it integrates well with applications, especially our cloud service Microsoft Azure , giving us complete visibility across our infrastructure for efficient operations and modern compliance.

Regarding improvements to user experience, while it is generally acceptable, I have faced some issues needing OS upgrades, which have occasional blockers. Support from Device42 has been helpful in resolving certain issues, particularly with dependency mapping. However, the asset inventory and certificate management functions work well.

My main use case for Device42  is for transformation projects to assess the application workloads of different organizations that are ready to move to cloud.

In one of those transformation projects, I used Device42  for assessing application dependencies and obtaining infrastructure details such as current usage, how applications are dependent on each other, networking components, memory, CPU, and other details. This allowed me to get the as-is information and application dependencies to define how to move the workloads forward and whether the applications were ready to move to cloud, essentially to check their readiness and fit for cloud migration.

I have used Device42 for transformation and modernization projects, and it has been very useful because I obtained as much detail as required for successful execution of the project.

Device42 offers great and detailed application dependency data, networking components, and provides as-is details with interconnections between applications.

The detailed application dependency data and networking components stand out in my projects because application dependency is a major factor that helps evaluate how applications and workloads will be migrated and in what move group. It is easier to define the move groups of applications to be migrated to cloud using the application dependency data, so I can easily decide what set of applications can be moved together. This is very helpful.

Device42 has positively impacted my organization by helping us lead successful migration and transformation projects, and I have successfully completed cloud movement implementation from standard data center deployments to the cloud. It was very helpful in both transformation and transition phases.

Device42 can be improved by adding more reporting features and architectural diagrams. If visual representations for application dependencies could be incorporated, that would be helpful.

I have been using Device42 for two years.

Device42 is stable.

Device42's scalability is good because it can handle larger workloads. I have not faced any challenges in terms of scalability with Device42.

Customer support for Device42 is effective. I receive responses to queries or issues related to the tool within 24 hours, and critical issues are also addressed quickly.

I was previously using other tools such as Azure Migrate  and Cloudscape before switching to Device42.

I have seen a return on investment because if I am well-versed with the tool, I would need fewer people to evaluate or perform manual assessment. In that way, it is helpful.

Before choosing Device42, I evaluated other options and found that Device42 is the more effective tool that can be used.

Specific outcomes and metrics from those migration projects that I can share include that I identified very accurate details. I did not face any migration issues, and the migrations were quick and effective. Application testing post-migration was also completed very quickly because I had the pre-assessment and assessment details ready to use because of Device42. It was accurate and very effective.

On a scale of one to ten, I would rate Device42 an eight. I chose eight because I think overall everything is great about the tool and it really helps in assessing applications and migrating workloads to cloud. However, I still feel there is always room for improvement in everything.

My advice to others looking into using Device42 is to explore their options. It depends on the organization and how they want to utilize which tool. I had a great experience using Device42, so I would recommend people to give it a try for transformation projects. I would rate Device42 an eight out of ten.

My main use case for Device42  is that I appreciate the advanced search capabilities and impressive dashboard. It provides accurate infrastructure visibility and documentation while simplifying data management tasks. It is very effective in identifying issues and planning for the future through its powerful dependency mappings of resources and applications. What stands out is automating database performance, optimizing workflows, and reducing costs. Whether on the cloud or on-premises deployments, Device42  proves reliable and adaptable to various network management needs.

Device42 has the ability to collect and configure data from storage devices, while it facilitates seamless communication with cloud services. In my organization, we use it as a customer data center infrastructure discovery, where we provide support to customers for the infrastructure inventory discovery.

Some of the best features that Device42 offers are that it can discover physical and virtual servers as well as network devices. It gives resource utilization details like CPU, memory, and storage. It provides dependency mapping and gives inbound and outbound communication details.

Device42 provides detailed information regarding the IT assets with Device42 installed and also helps in the identification of assets and their locations.

Device42 has positively impacted my organization because since it was installed, it has been very helpful because we use it for mass updates, which saves us a lot of time; approximately sixty to seventy percent of our time is saved through the mass updates. It helps in making everything documented, hence being very focused. With this system, we can get any information about the location of the device, connected cables, additional information, and status. Inventory management has been very seamless.

Device42 can be improved by adding more widgets in the dashboard with correct information. Different fonts and color themes are lacking in the user interface. Modern graphics elements would be better. Sometimes it is time-consuming.

Device42 could benefit from improvements, specifically regarding the deployment of the software, which sometimes can be hectic and become time-consuming.

I have been using Device42 for seven years.

Device42 is stable.

Device42 is highly scalable.

The customer support for Device42 is excellent.

I previously used a different solution, which was Strapi , and I switched to Device42 for its enhanced capabilities.

I have seen a return on investment with Device42. Device42 is a fully-featured tool that includes everything we need with powerful auto-discovery and intelligent application dependency mapping. It is great in saving time and cost.

The pricing, setup cost, and licensing for Device42 are relatively cost-effective and affordable. I do not know if a small organization would be able to afford it, but I presume it would also be cost-effective on their side.

The advice I would give to others looking into using Device42 is that with Device42, we are able to feel the value of our money. Since we mainly use it for DCIM  and network discovery, it does a great job. I would rate this solution an eight out of ten.

My main use case for Device42  is building the as-is for the customer while discovering the virtualization environment, whether it's Azure , VMware, or Hyper-V , and adding the VMs which are important to it and related to the application. After that, I build the Application Dependency Mapping (ADP) to show the customer which applications are more important for building business resilience, creating a report that highlights which business or application is the most critical.

A quick, specific example of how I used Device42  for this project is its main purpose, which is to build all the application dependency mapping. The tool captures all connections to or from the server and displays them in the file, which helped me immensely because it sniffs all the servers, collecting tons of data simultaneously. This capability is something the network team or security team could never manage within a similar time frame; capturing all this traffic at once would take them a much longer amount of time.

The best feature Device42 offers for me is the Application Dependency Mapping (ADP).

What stands out to me about the Application Dependency Mapping feature is both its accuracy and visualization.

Device42 positively impacts my organization because we build the as-is as soon as possible. It helps us avoid the delays that would occur if we went to the network team or security team, which would take much longer than what Device42 requires. With Device42, I captured more than 100 traffic entries in just two weeks, which was great.

An additional positive outcome I noticed is that it would be nice to have a video showing how to install and use Device42, as sometimes the documentation is not clear. A video would make it more efficient. Additionally, when I contacted support about a corrupted file as shown in the documentation for the ADP, the file they provided was not useful. Fortunately, a team member with experience assisted me with the BI server, which was better. Improving the documentation to be clearer and adding a video would be helpful.

I chose a nine for Device42 because it captures a lot of traffic in no time, which is perfect for me, and it is straightforward and easy to use. However, the documentation has not been updated in a while, so it needs updates. To reach a ten, I would prefer a feature that allows for smaller intervals for scheduling, ideally running every one hour or less, instead of just once a day at one o'clock AM.

I have been using Device42 since I just finished the project I started in August 2025, and we completed it in January 2026.

Device42 has been very stable in my experience.

Device42's scalability works well for me; if I want to add more resources, such as a Remote  Collector for a new site, I can easily connect it to the main appliance.

The customer support for Device42 is perfect; they respond in less than 24 hours and follow up, which I really appreciate.

Previously, this work was done manually, extracting from RV tools, sniffing one by one, and using Watchdog, which was painful.

I have seen a return on investment from using Device42, as I was the only one who did the full exercise and it was easy for me. I worked about 8 to 16 hours per week, which was sufficient to deliver. This efficiency with time and resources was perfect; however, I do not know about the costs since I am not involved in that aspect.

I have nothing else to add about my main use case or how Device42 helped in this project.

I do not have anything else to add about the features or any smaller details I found handy.

My advice for others looking into using Device42 is to follow the steps in the documents, and if you encounter any obstacles, do not hesitate to contact customer service, as they are perfect, supportive, and reply quickly.

An additional thought I have about Device42 is that if you could create a video, that would be perfect for me.

I gave Device42 a rating of 9 out of 10.

My main use cases for Device42  are the asset management package and the CMDB  package. A specific example of how I use Device42  for asset management and CMDB  is that for the CMDB and asset management parts, it was used for a customer environment in a commercial bank to help them have a detailed inventory of all their assets, including PCs, CCTVs, and more. With the CMDB package, they were able to have the same inventory of all their assets while also showing their interdependency and how they are all connected within the customer's network, also in a commercial bank. It was very helpful.

Device42 offers excellent features that include application dependency mapping and asset management where you can see your physical devices, PCs, storage, network devices, and more. Device42 as a whole has all top-notch features, and there is no feature that is not useful. With Device42, you can also integrate with other tools and supported software, so it has great features.

I find myself relying on asset management the most, and what makes asset management stand out is that most enterprise businesses want to have visibility into all their assets and who is being assigned to each asset. There is granular visibility where they can find the IP address. When they have a PC, they can identify which IP address belongs to a specific staff member or employee, and they can get to know the software updates on it, the make, and the access that person has within the environment. It includes not just the features that they can see on the user's device; they can see granularly what needs to be fixed on that device. For an enterprise environment, it gives visibility into all assets and employee activity on those assets.

One other feature that people often overlook is the benefit of asset management. Asset management goes beyond just seeing PCs and extends down granularly to software licenses and the PC's MAC address. With this feature, I can easily assign and reassign devices and know when a device is online or offline. This is especially valuable for virtual solutions, virtual software, and services, as it helps identify what has been captured and what is missing in the inventory, allowing for working towards making it visible by capturing it in the discovery setup.

Device42 has positively impacted our organization by helping us become one of the best companies for asset management and inventory for the enterprise businesses we work with. With Device42, I have been able to work with several commercial banks where they use this solution and they are impressed and happy with the results. They can see down to their storage devices, network devices, storage, and more. They can see everything listed in one click, with the whole inventory displayed, and reports can be generated. It has really helped our business and serves as a good business selling point.

Device42 can improve in the area of updates. If automatic updates were available for the solution instead of having customers go through the process of downloading and uploading update packages themselves, it would be beneficial. I would also mention that support response time could be faster.

I have been using Device42 for two years.

After a few contacts and communications during setup for customers, they are able to handle it by themselves because it is easy to understand. It is not complex; it is straightforward. When it comes to resolving technical issues, the support team is responsive and always available to help.

I have noticed measurable outcomes, such as an increase in customers. More enterprise businesses are looking to get Device42 for their asset management. They are moving away from Lansweeper  and choosing Device42 instead. They are replacing other asset management solutions with Device42 because it has a broader scope and wider visibility into their environment. Device42 is easy and fast during onboarding, making the implementation efficient.

My advice to others looking into using Device42 is that it is a great solution. All questions and answers when it comes to a CMDB tool, asset management tool, and the visibility you want for your company are provided by Device42. You can discover down to your MacBooks, IP phones, and printers, as everything can be found using Device42. You can also see their interdependencies and manage your licenses and every other aspect. I think Device42 should also expand its focus on working with West Africa, as there is significant opportunity in that region. Device42 should partner with companies to deliver the service and solution to customers in West Africa. I would rate this solution a 9 out of 10.
