Risk-based visibility has transformed how I prioritize cloud vulnerabilities and protect key assets
The best features Qualys TotalCloud offers are cloud asset visibility, vulnerability assessment, and risk prioritization. This risk-based prioritization helped me quickly identify high-risk vulnerabilities and focus on remediation instead of going through every finding. TrueRisk-based prioritization is useful for understanding which vulnerabilities need attention first. It improved our workflow mainly by giving us a single view of cloud assets and their risk, so we could focus on the higher priority vulnerabilities instead of reviewing every finding manually. This helped us prioritize remediations more efficiently and reduce the time spent on vulnerability assessment and follow-up. Qualys TotalCloud helped us identify exposures that might otherwise have been missed, especially across cloud assets, vulnerabilities, and identities. With the SaaS configuration, the unified inventory and risk view made it easier to connect vulnerabilities with asset criticality, exposure, and access permissions, allowing us to investigate high-risk exposures first and address them before they could become bigger security issues.

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.

Manages vulnerabilities effectively over time but needs improvement in web coverage and dashboard flexibility
Most of the dynamic asset tagging we use is manual, not dynamic. To manage the assets, we employed the manual approach because we have a limitation regarding the license, so we don't use the dynamic approach much. I don't know how the configuration assessment has assisted with meeting compliance standards. The product that we use is the on-premise solution where we configure assets and dynamically scan them. However, we use the default policies more, the template, so Rapid7 InsightVM on-premise version is not that effective in the web-related systems. However, it is best on the OS to identify and discover the OS-related vulnerabilities, more of open ports and the discovery of vulnerable ports or services. It would be better to improve Rapid7 InsightVM by including or working better to add web-related templates because it's not that effective in regard to web. I don't know if they may have a separate product regarding the web, but for the on-premise type, they are not strong in this area. I would prefer to see web-related templates in addition to improving the dashboard-related things because the dashboard has been constant for a very long time. It would be better to see various kinds of, perhaps a flexible type of dashboard. If it's not customizable at all, I would want to see the risk and asset over time with more flexibility. The current dashboard is not flexible in this regard; I have to dig down every day, so they should work on this as well, in addition to the web.
