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.
Brent Hamlin - PeerSpot reviewer
Infrastructure Manager at a construction company with 501-1,000 employees
Continuous threat scanning has improved remediation time and strengthened executive reporting
The best features that The NodeZero Platform by Horizon3.ai offers include the automated scans, which are great to use; you set it, scope it, and let it go, which works really well. The executive reporting feature is impactful for me as a manager, providing a strong foundation to give quarterly and yearly reports to our executives and board to see the state of our infrastructure from a security standpoint. The level of detail and clarity in the executive reports from The NodeZero Platform by Horizon3.ai absolutely helps me communicate effectively with leadership. They are detailed enough for me to extract the necessary information tailored for the executives and to provide a broader perspective on our mitigation efforts or accepted risk stance and where additional controls exist. The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization. It allows us to run scans whenever needed, unlike a single third-party system that only provides a snapshot in time; our processes must be ongoing as the security landscape is dynamic. NodeZero's endpoint security effectiveness feature impacts my understanding of potential security threats by providing a clear picture of both the external and internal landscapes within my organization, enabling me to prioritize and adjust as needed for vulnerabilities such as WordPress plugin issues or user enumerations and software code version assessments. I have built The NodeZero Platform by Horizon3.ai into our weekly and monthly workflows for security CI/CD, and we scan our externally accessible assets every week to address anything quickly if it comes up. That includes our firewalls, websites, and anything that is an external web server, which we scan weekly, while the monthly scans are for internal systems that feed our security CI/CD pipeline, enabling us to action across and prioritize any vulnerabilities caught by The NodeZero Platform by Horizon3.ai.
Vikram Chakravarthy - PeerSpot reviewer

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.
