Real-time assessments have improved remediation speed and reduced time spent on authentication issues

Threat & Vulnerability Management Senior Analyst at a tech vendor with 10,001+ employees

I do find that here and there with Contrast Security Assess there are user interface issues, particularly with how they work with libraries. The way that it works is people have access to library data for all applications, not just the applications that they should have access to. However, they are trying to fix that. The way the libraries are handled with Contrast Security Assess could use some work. I know that there is an additional service tier that allows for more in-depth library data. These are small things. Contrast support has been great in fixing any issues or getting back to us with questions. They seem to really be dedicated to the product.

Unified vulnerability view has improved risk-based decisions but reporting still needs work

Vulnerability And Compliance Manager at a insurance company with 5,001-10,000 employees

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.
