Resource Availability Analysis

Budget constraints significantly impact tool selection. Enterprise SAST and DAST platforms can cost hundreds of thousands annually, while IAST often prices per application or runtime instance. Open-source alternatives exist for all approaches but require more internal expertise and support. Total cost of ownership includes not just licensing but infrastructure, training, and ongoing operations. Budget realities might phase implementations, starting with one approach and expanding over time.

Technical expertise availability shapes successful implementations. SAST requires security professionals who understand code analysis, can tune rules, and interpret complex findings. DAST needs personnel familiar with web application security and penetration testing concepts. IAST demands operations expertise for agent deployment and performance tuning. Limited expertise might favor tools with better vendor support or simpler operation models.

Time constraints affect both initial deployment and ongoing operations. SAST typically requires significant upfront tuning to reduce false positives to manageable levels. DAST can provide immediate results but needs ongoing configuration for comprehensive coverage. IAST deployment complexity varies by environment but generally exceeds other approaches. Consider both implementation timelines and steady-state operational requirements.
