Penetration testing vs vulnerability scanning

A vulnerability scan enumerates known weaknesses. It is fast, repeatable, and only as good as credentials and coverage. It will not notice that your password-reset flow issues tokens for other users.

A penetration test is a time-boxed attempt to achieve objectives: read another tenant’s data, reach domain admin, move from a phishing foothold to finance. The output is evidence, not a CVE catalogue.

You usually need both. Scanning is hygiene. Testing is assurance. If your budget only allows one this quarter, choose based on the question you must answer. Insurance questionnaires often want a pentest. Patch programs want a scan with triage.

ShadowSec Lab will not sell you a scan dressed as a pentest. If breadth is what you need, we will say so and price a vulnerability assessment honestly.
