Comparison
Autonomous testing vs vulnerability scanning
A vulnerability scanner tells you what looks wrong; an autonomous test tries to prove it and drops what it cannot.
How do they differ in practice?
The differences that change a purchasing decision, side by side.
| Approach | Output | Authenticated coverage | Access control testing | What you do next | False positives |
|---|---|---|---|---|---|
| Autonomous testing | Findings with evidence | Logs in, and can register its own test account | Tests one identity against another | Read the report | Re-tested, and refuted when not reproducible |
| Vulnerability scanning | Detections with a confidence score | Usually anonymous unless configured | Not attempted | Triage the list yourself | Carried through to the report |
Scanning is a useful input. It is not a penetration test, and presenting its output as one is how a team ends up with a hundred open items and no idea which two matter.

Set an envelope and read the output.
