IT Security Expert at Alior Bank S.A.
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.

Cyber Security Engineer II (Vulnerability & Threat Management) at FICO
Risk-based workflows have transformed how our teams prioritize and track critical vulnerabilities
One important area for improvement could be reporting flexibility and dashboard customization, as this would need to align with specific organizational requirements. I believe it could be better. Additionally, UI simplification and more customization around workflows and reporting would further enhance the analyst experience. Improvements in executive reporting, more customizable dashboards, and deeper workflow flexibility would enhance operational usability further. Vulcan Cyber handles scalability well in our organization. It maintains stability for visibility and remediation tracking, avoiding the need for additional storage, as it is cloud-based. It scales well in our environment, even as vulnerability data and assets grow significantly.
