Sr Security Engineer at a tech vendor with 5,001-10,000 employees
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.

Cloud risk has become visible and security teams prioritize and act on threats efficiently
FortiCNAPP can be improved because the platform can feel complex at the start, especially for teams new to CNAP tooling. Some users mention that they found the interface and data models less intuitive than expected, and I have had situations where reporting and alert configurations might require time. Regarding other improvements needed for FortiCNAPP, the majority of the time is that reporting and alert configuration might require time to tune properly. This is the significant issue, combined with the fact that some users find the interface and data model less intuitive than expected. Regarding FortiCNAPP's AI capabilities, I think there might be a bit of improvement needed. However, since Fortinet is a security vendor overall, keeping the data safe is not a problem. I know they have invested a lot in getting it to a place where it is a trusted platform.
Irfan Sharfi - PeerSpot reviewer
Security Professional at a tech vendor with 10,001+ employees
Micro-segmentation has transformed endpoint protection and now isolates internal threats effectively
Illumio can be improved in several areas based on our feedback. Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices. When these devices communicate within the network, loading the map or connections can cause latency, which needs improvement for a more user-friendly and faster experience. Regarding improvements to the interface, I believe we can add more features to the graphical user interface, such as proper logs. While the logs currently indicate what was blocked or allowed, clicking on a specific log should provide more information, such as which extra-scope rule is causing a denial, offering better analysis for troubleshooting.
