CST VerdictBased on our analysis of NIST CSF 2.0 coverage, company size fit, deployment model, here is our conclusion:
Red teamers and penetration testers validating authentication bypasses will find XSSOauthPersistence valuable for demonstrating account persistence through XSS-to-OAuth chaining, a vector many security teams underestimate during assessments. The 77 GitHub stars and free pricing mean you can integrate it into your standard engagement toolkit without budget friction. Skip this if you need a polished commercial platform with reporting templates; this is a focused exploitation primitive, not a full-stack pentest framework.
Mid-market and enterprise teams that need to prove their defenses actually work against real adversary tactics will get the most from FourCore ATTACK. Its adversary emulation engine forces you to test detection and response workflows with evidence of what failed, moving beyond checkbox compliance toward ID.RA risk assessment that sticks with your board. Skip this if your team lacks the security maturity to act on emulation findings; the tool surfaces gaps faster than your people can typically close them.
