Scanning finds possible weaknesses

A scanner rapidly checks many assets for known patterns. It is valuable for breadth and repeatability, but its output can include false positives or miss contextual attack paths.

Testing proves impact

A penetration tester investigates whether findings are reachable, exploitable and meaningful in your environment. They can chain smaller issues and interrogate bespoke logic.

Use both for different jobs

Continuous scanning supports visibility. Human validation creates certainty. Together they deliver efficient coverage without treating automated data as the final answer.
