Nucleus Security requires intuitive UI, enhanced reporting, streamlined integration, and better onboarding with customizable dashboards and exposure management.
That's not a limitation of Mend.io; I think that's a general problem with any tool in the market because no tool in the market will actually know what portion of the code I'm actually using from that particular library if it is vulnerable or not.

CEO at a computer software company with 10,001+ employees
Centralized security monitoring has reduced false positives and improves dependency governance
The only area for improvement I would say is that the false positives are nearly zero; everything is mostly like 99 to 99.99% or we can say 100% accurate. There were a few areas for improvement just from the last time I saw; I think the user experience had a little problem. We wanted to have certain reports based on our kind of scenario, but the tool did not allow us to create custom reports. We had asked for some facility and some ability for us to create some custom reports. That would be awesome if they allow us to create custom reports the way we wanted. There is one small area which I don't know whether we should call a tool limitation or a wish list; if I use a library and I don't use all the capabilities of the library but only a portion of it and that portion is not vulnerable, but there is a component which is outdated, that is a problem, even though I don't use that component. Mend.io will discover there is a problem in the whole library; that is correct. That's a valid discovery, but in my case, for example, if I don't use that particular portion, then it actually is not making sense for me, but that's not a limitation of Mend.io; I think that's a general problem with any tool in the market because no tool in the market will actually know what portion of the code I'm actually using from that particular library if it is vulnerable or not.

Vulnerability And Compliance Manager at a insurance company with 5,001-10,000 employees
Unified vulnerability view has improved risk-based decisions but reporting still needs work
One of the main issues with Nucleus Security is its lack of reporting capability. The user interface resembles an early 2000s application style, and although its speed is decent, it could be improved as more data is ingested. The overall appearance and feel need work, especially compared to modern applications from Rapid7, Qualys, and Tenable, which have more engaging user interfaces. The reporting capability is severely lacking; not being able to filter to granularity or have custom built queries is an annoyance that needs an overhaul. Additionally, there are bugs that have not been resolved, such as when you create a report and remove an asset, the asset still appears in the report despite not being present in the system anymore, leading to issues that need to be addressed quickly. Nucleus Security can become a difficult investment because I already have a vulnerability management solution, and I question where Nucleus Security fits with its licensing model. While I acknowledge automation has been described, it would be amazing to control the entire vulnerability management workflow from Nucleus Security without needing to log onto other systems. Having controls or actions that can be sent from the console down to the scanner for rescans would be beneficial. If Nucleus Security is going down this path, it should ensure that it becomes a one-stop shop for vulnerability management across multiple applications.
