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.

Improved our security posture thanks to comprehensive visibility
I have contacted Wiz technical support frequently. The support is excellent. We contact via an in-application portal. We can see the support cases we personally open, and also the cases that other people have opened from our company. I appreciate that feature. Generally, support gets back to us within a few days with a good answer. There was one fellow in particular who has been knocking it out of the park. He is a great support person to deal with. We are happy with the support experience. If I were to put Wiz support on a scale from one to ten, I would give them a ten.
