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.
Nykole Denoo - PeerSpot reviewer
Cyber Security Analyst at BNY
Cloud risk visibility has transformed how I prioritize threats and reduce unnecessary spend
From my perspective, Orca Security is a really good tool. I would say one area I would like to see CNAPP platforms get is more intelligence when it comes to risk prioritization, which correlates with vulnerability, exposing assets, identities, and active threats to help the security team focus on risks that are more likely to be exploited. I am a huge advocate for automation. I also think deeper automation for remediation or stronger integration with ticketing and CI/CD pipelines or more customization would help. Executive reporting would help the security team respond significantly faster and communicate risk more effectively if those kinds of improvements are made.
MohammedJaffir - PeerSpot reviewer

Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.
