Your Critical Vulnerabilities Might Not Be Your Biggest Risk
Security teams should prioritize vulnerabilities based on exploitability, not just severity scores.
The article argues that traditional vulnerability severity scores can be misleading. Instead of solely focusing on critical vulnerabilities, security teams should adopt autonomous penetration testing to validate attack paths. This approach helps identify which vulnerabilities, even those of medium severity, pose the greatest actual risk by considering exploitability, chaining potential, and access to sensitive systems.

The lesson from this incident
Full lessonOrganizations that prioritize remediation solely based on CVSS severity scores may be leaving their most dangerous attack paths unaddressed. A medium-severity vulnerability that chains with others to reach a critical system can pose far greater risk than an isolated critical vulnerability with no viable exploit path. This matters because attackers don't follow severity rankings — they follow the path of least resistance to the highest-value target. Without validating real-world exploitability and attack chaining potential, security teams are effectively flying blind when allocating remediation resources.
What helps against this
How we list vendors- Vulnerability scanning and prioritisation
You know which systems are vulnerable, and which ones to fix first.
- Breach and attack simulation
You only find out whether your security tools stop an attack when a real attacker tries.
- Network segmentation and microsegmentation
One compromised machine can no longer reach everything else.
