Why Leaked Secrets Demand More Than SAST and DAST Security Tools

Static and dynamic application security testing tools are widely used to detect vulnerabilities, and many do include rules for flagging hardcoded credentials. However, a leaked secret fundamentally differs from a conventional vulnerability because it requires no exploit — an attacker simply copies a valid key and authenticates directly. In 2025, credential abuse featured in 39% of breaches, often enabling lateral movement beyond the initial entry point. SAST and DAST are designed to identify exploitable weaknesses in code and runtime behavior, but they were not built to manage the active access risk that a live, exposed credential represents. Secrets security therefore requires dedicated tooling — including provider-aware validation to confirm whether a credential remains active — sitting alongside, not replaced by, traditional application security testing.
