- When processing untrusted inputs
- Security audits of agent-generated code
- Compliance verification (OWASP Top 10, CIS)

## AIDefence Layers

1. **Prompt Injection Detection** - Pattern + heuristic blocking
2. **Input Validation** - Path traversal, type coercion, parameter sanitization
3. **Static Analysis (SAST)** - Vulnerability scanning, CWE matching
4. **Sandboxed Execution** - Network isolation, filesystem restrictions, resource limits
5. **Output Sanitization** - Secrets, PII, injection vector redaction

## Security Levels

| Level | Layers | Use Case |
|-------|--------|----------|
| standard | SAST + validation + sanitization | Routine audits |
| elevated | + threat modeling + compliance | Pre-release audits |
| maximum | + sandbox + full STRIDE + remediation | Critical systems |

## Agents Used

- `agents/security-auditor/` - Vulnerability detection
- `agents/reviewer/` - Code quality verification
