Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

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.

Extensive exploit database and seamless integration enhance penetration testing capabilities
The automated approach in the audits or in the hacking testing with Rapid7 Metasploit could be improved because even the same attack you provide today will go in different ways another day. I prefer when the auditor or pen-tester provides the attack in a non-automated mode. For some, it might be a valuable option, but I'm not sure it's valuable for us, as after the attack has been provided, we should release a report detailing how it transpired and what the customer should improve to block this way of attack. If the attack was provided in an automated mode, you cannot receive sufficient information that helps with this final report for the customer. While you can check the vulnerability, and the system will tell you there is no vulnerability, usually, a human can change one, two, or three parameters and using the same technique and the same scripts can break the system. Rapid7 Metasploit could be improved in areas concerning the experience with finding particular scripts pre-installed in the solution. Customers, administrators, and pen-testers spend considerable time trying to locate the specific component they need by the name of the technique or the name of the attack, so any improvements in making it easier to find those predefined components by name or timeframe would be beneficial. Search filters could be a correct improvement.
