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.

Centralized monitoring has strengthened cloud posture and prioritizes critical security risks
The best features Sophos Cloud Optix offers are cloud security posture management, CSPM, continuous monitoring for misconfiguration, compliance reporting, and centralized visibility across multi-cloud environments. I also find the risk prioritization helpful, as it helps me focus on the most critical security issues first, and the intuitive dashboards make it easy to understand the overall security posture. Additionally, the alerting and reporting capabilities help my team respond to issues quickly and maintain compliance with organizational security standards. Sophos Cloud Optix has positively impacted my organization by improving my visibility into cloud security and helping me identify misconfigurations before they became security incidents. It has reduced the time required to detect and investigate potential risks by providing prioritized alerts and centralized dashboards. As a result, my team responds to security issues more effectively and spends less time on manual reviews. It has also supported my compliance efforts by providing clear reporting and continuous monitoring, which has strengthened my overall cloud security posture.

Has significantly improved proactive monitoring through automated asset discovery and seamless integration with cloud environments
Making the system smarter would be beneficial. Adding modules for integration with AWS and Azure would be helpful. Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable. When discussing a big company, it is mandatory to have tools that will assist us rather than waiting for manual input to add hosts. Adding assets manually is prone to mistakes. Humans might forget to add an asset or make errors when adding multiple assets. Taking the human element out of the context and making it more streamlined is the future for security. The human should be involved where expertise is needed, such as analysis and decision-making. Currently, with resource constraints, we need tools to collect and aggregate data, eliminate false positives as much as possible, and present relevant information to employees for action.
