Contrast Application Security Testing (AST) vs Contrast Runtime Security Platform: Side-by-Side Comparison (2026)

Contrast Application Security Testing (AST)

Development teams shipping code faster than they can manually review it should use Contrast Application Security Testing to catch real vulnerabilities before production without slowing the build pipeline. Its runtime instrumentation monitors actual code execution across Java, .NET, and Python, eliminating the false positives that plague static scanners, and integrates directly into Jenkins and GitHub workflows so findings surface where developers already work. Skip this if you need pre-deployment scanning as your primary defense; Contrast is strongest when your applications are already running and you can instrument them end-to-end.

Contrast Runtime Security Platform

DevSecOps teams at mid-market and enterprise companies will get the most from Contrast Runtime Security Platform because it catches vulnerabilities and active attacks simultaneously during development and production, not just at gates. The platform covers five NIST CSF 2.0 functions including continuous monitoring and adverse event analysis, with runtime instrumentation that provides context most static testing tools miss. Skip this if your organization needs supply chain scanning as a primary function; Contrast treats that as visibility only, not as its core enforcement mechanism.
