Risk-based triage has transformed container security and now prioritizes high-impact threats
The best features Qualys TotalCloud offers currently include managing cloud infrastructure and container security while facing major challenges such as alert fatigue. Traditional vulnerability scanners flag hundreds of CVEs on short-lived Kubernetes containers, some of which have no internet exposure or are gone before we can even triage them. I leverage Qualys TotalCloud to move beyond static CVSS. I use it to implement runtime exposure, correlation risk reprioritization, and shift-left integration. This notifies developers to fix a base image upstream rather than patching live ephemeral instances. In my work with cloud and container security, the biggest operational hurdle was alert fatigue. I use Qualys to shift left from static CVSS severity to context-aware risk prioritization. I correlated raw vulnerability data with real-time risk factors such as public network exposure, active runtime execution, or overly permissive IAM roles. This allows us to immediately drop the priority of isolated containers and escalate lower-severity CVEs that sit on an exposed, high-risk path. We can map these findings directly back to our CI/CD pipelines so developers can patch the root base images upstream. We have drastically cut down the signal-to-noise ratio, saved a lot of manual hours doing triage work, and ensured engineering effort goes directly towards high-impact risk reduction.

Image scanning has supported consistent security practices during cloud deployment
On a scale of ten, we would say people are happy with Prisma Cloud by Palo Alto Networks for the part we use. People are okay with it. We probably would give an eight. We don't give ten because if we don't use the other parts of Prisma Cloud by Palo Alto Networks, it's because it was difficult to implement from an operational point of view. We could have deployed the runtime monitoring with Prisma Cloud by Palo Alto Networks, but within our organization at our company, it was very difficult to find who would be the owner for the alerts. People have other tools and in the end, we don't use the full capabilities of a product that we pay for. It's partially related to the difficulty to integrate Prisma Cloud by Palo Alto Networks runtime in our company's support process. We don't use the real-time monitoring part of Prisma Cloud by Palo Alto Networks. We don't know about the automated remediation feature of Prisma Cloud by Palo Alto Networks.

Centralized analytics have strengthened patch visibility and support efficient regulatory reporting
From my experience, I assess the product's analytics capabilities as successful. It helped us significantly with patching and managing the risk of the patching process across all our environments, including network devices with Windows and Unix systems. The product covered several environments and gave us exactly what we needed in our environment. Tenable Security Center's centralized platform helped with risk assessment and management across our IT environments. It covered the patching process, and we previously faced many issues regarding how to patch different environments, how to monitor the patching process, and whether it was successful or not. We obtained good reports showing when patches were closed and the details of each patch, including who executed it and everything related to the patching process until it was closed. This gave us good details about the process which helped us significantly in our reporting and even in audits, whether internal or external. We learned how to close audit issues safely and successfully. We used the dashboards for real-time threat insights and extracted several dashboards from Tenable Security Center. We use these dashboards in our cybersecurity dashboard and committees that we have. These dashboards are part of our committees, especially the cybersecurity committee and other committees that we attend.
