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.

Provides centralized visibility and real-time threat detection across multiple cloud accounts
Regarding how CrowdStrike Falcon Cloud Security can be improved, I would say they can improve their support. There were a couple of cases where we needed to escalate issues in order to get proper support. That part could use some tweaking on their end. Additionally, the recent incident during the last summer literally impacted our systems. We had some of our workloads that affected the business, and it was a difficult experience. Apart from that, it is a good tool and the experience with CrowdStrike Falcon Cloud Security has been excellent. We did not find any kind of issues, but if they could improve their response to security-related incidents and provide on-time support or better understand our concerns and address them accordingly, it could be very helpful. Regarding needed improvements, I think they should enhance automatic alerting with CI/CD scanning and reporting capabilities. Additionally, it would be better to implement Falcon sensor health monitoring so agents are always active. We could know how it is behaving and how it is treating our environment. That could be a little helpful.
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.
