We wanted to move beyond just 'checking the box' on pentesting. Cobalt enabled us to build a modern pentesting program with multiple assessments throughout the year. We're now proactively managing risk through a continuous, data-driven security program.

I haven’t had a single vulnerability back from Cobalt that isn’t a real issue. I can hand them to the engineers with confidence that they are genuine, exploitable vulnerabilities. That’s a huge time savings and a much higher value process.
