VA vs PT: What's the Difference?
| Aspect | Vulnerability Assessment | Penetration Testing |
|---|---|---|
| Goal | Identify vulnerabilities | Exploit vulnerabilities |
| Depth | Broad, automated scanning | Deep, manual testing |
| Risk | Low risk | Higher risk (controlled) |
| Output | List of vulnerabilities | Proof of exploitation |
| Time | Hours to days | Days to weeks |
| Skills | Tool-based | Highly technical |
