TL;DR: Choosing a SAST tool is less about feature checklists than about fit, developer workflow, language coverage, custom rules, integration, and proof of concept testing, according to Semgrep. The real risk is selecting tooling that looks capable on paper but creates friction, blind spots, and low adoption in practice.

Questions worth separating out
Q: How should security teams choose a SAST tool without creating developer friction?
A: Start with the delivery model, not the feature list.
Q: Why do SAST programmes fail when language and framework coverage is incomplete?
A: Because incomplete coverage forces teams to run multiple scanners, write manual compensating rules, or accept blind spots in important parts of the codebase.
Q: What do teams get wrong about custom SAST rules?
A: They often treat rule creation as a one-time setup task.
Practitioner guidance
- Map SAST access to least privilege Inventory every repository, IDE, CI, and cloud integration the tool requires, then reduce access to the smallest set of read-only permissions needed for scanning and reporting.
- Test language and framework coverage against real code Run the product against the actual languages, frameworks, and internal libraries used in production rather than a sample project.
- Measure developer friction during proof of concept Evaluate false positives, review time, IDE performance, and CI latency with the engineers who will use the tool daily.

SAST tool selection: what governance gaps should teams test?
Explore further
SAST selection is now a governance problem, not just a tooling problem. The article is really about alignment between analysis depth, developer workflow, and operational tolerance for friction. A tool that cannot fit the delivery model will be bypassed, no matter how strong its detection claims are. For security leaders, the selection question is whether the programme can absorb the operational cost of the control, not whether the control exists in theory.
A question worth separating out:
Q: What should organisations check before giving a vendor access to source code?
A: They should review exactly which repositories, branches, tokens, and service accounts are required, then constrain the access to the minimum necessary for scanning. The security team should also verify offboarding, rotation, and logging so source code access does not persist after the tool is removed or replaced.
