reviewer2859021 - PeerSpot reviewer
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.

NitishKumar - PeerSpot reviewer
Consultant at a manufacturing company with 10,001+ employees
Crowdsourced security has strengthened our bug discovery and improved vulnerability response
HackerOne is already doing well, although I believe implementing stricter SLAs for the time to first response and time to bounty would help prevent researchers' burnout, especially regarding duplicate submissions. I suggest systematic bug rewards because currently, if a researcher finds one bug in multiple places, they often only get paid for one. Improving the handling of systemic vulnerabilities would encourage deeper research. Additionally, improving multi-currency and crypto payout options would help make the platform more accessible globally.
