CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:

postMessage-tracker

Frontend developers and security teams hunting client-side postMessage vulnerabilities will find immediate value in postMessage-tracker; it surfaces cross-origin messaging flaws that traditional DAST tools routinely miss because they don't instrument browser APIs at runtime. The Chrome Extension's 1,200-plus GitHub stars and zero-friction deployment mean you get signal on the first day without staging a full security scan. Skip this if your threat model doesn't include third-party iframe exploitation or you're already running a maturity level where every postMessage listener has explicit origin validation baked into code review.
