+# SAST (Static Application Security Testing)
+
+Static application security testing (SAST) is a set of technologies designed to analyze application source code, byte code and binaries for coding and design conditions that are indicative of security vulnerabilities. 
+SAST solutions analyze an application from the “inside out” in a non-running state.
