What it means
Each method sees different evidence and has different coverage, timing, false-positive patterns, and deployment requirements. They work best as complementary controls rather than competing replacements.
Why it matters
Combining methods improves visibility across coding defects, runtime behavior, configuration, data flow, and reachable attack paths.
Practical focus
- Match each technique to the technology and risk
- Run tests at useful points in the delivery pipeline
- Tune rules and validate high-impact findings
- Measure remediation and recurring defect patterns
Common mistakes
- Buying tools without defining ownership
- Blocking releases on untriaged noise
- Assuming one method covers business logic
- Scanning only immediately before production
