Why the models rank Checkmarx One — on best sast tools for polyglot monorepos
“The strongest traditional enterprise SAST for breadth — ~35 languages including legacy stacks (COBOL-adjacent, PL/SQL, Scala, Apex) that Semgrep and CodeQL skip, scans without a full build, and mature triage/policy tooling that suits large orgs where one monorepo spans a dozen teams and compliance regimes. Assumption: the buyer is an enterprise AppSec team, not a startup.”
