White-box penetration testing gives the tester full access to your source code, architecture, APIs, and internal logic. This enables deep manual review and exploitation of vulnerabilities like SQL injection, broken access control, and business logic flaws that scanners or black-box tests miss.
Skyline delivers white-box assessments in 48-72 hours with zero false positives, working PoC exploits, and copy-paste fixes. Starting at $1,997.

| False Positives | Zero — manual verification | High (60-80%) | Medium |
| Time | 48-72 hours | Days to weeks | Varies |
| Best For | Pre-launch, compliance, SaaS | Quick external scans | Hybrid |
| Remediation | Copy-paste fixes in your stack | Generic advice | Some specifics |
