Decision Framework Application

With requirements understood, apply a structured decision framework. Start by eliminating approaches that fail hard requirements—IAST without runtime compatibility, SAST without language support, or any tool exceeding budget constraints. This elimination often significantly narrows options, simplifying subsequent decisions.

For remaining options, score tools against weighted criteria. Technical capabilities might include detection accuracy, false positive rates, and coverage completeness. Operational factors encompass ease of deployment, ongoing maintenance, and integration capabilities. Business alignment considers cost, vendor stability, and support quality. Weight criteria based on organizational priorities—a startup might emphasize ease of use while an enterprise values comprehensive coverage.

Consider phased implementations rather than all-or-nothing approaches. Many successful programs start with DAST for immediate visibility, add SAST as development practices mature, then implement IAST for high-value applications. This progression builds security expertise while delivering incremental value. Phasing also spreads costs and change management across time.
