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.

Automation has saved time and improves secure, centralized patching across all our devices
While Automox has very good features, I think there's still room for improvement. I want the custom reports to be even more detailed, specifically where I can add more details. It would be nice to have more filters in reports based on location and department more easily. Secondly, the notifications could be more customizable. Many times notifications come, but we don't have control over which notification is urgent and which is not. For example, if there's an alert of a critical update or pending approval, it can help me focus better. An alert of a security threat could be another type of notification that tells me something is important. Customized notifications would be much better. I would say the user interface could be improved as well. Some parts of the dashboard are a bit hard to understand. If they could be improved to be more intuitive, for example, if it could be easy to navigate between devices and reports, that would be great. I would say if Automox could also provide automation templates, that would help. I know there are templates, but I want more templates. Having ready-made worklets for common tasks can save a lot of time. Lastly, it should also support the interface for mobile screens.

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.
