CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Startups and SMBs that need pen testing but lack in-house expertise will move fastest with Aikido Attack; same-day reports and automated remediation pull requests compress what normally takes weeks into hours. The platform covers OWASP Top 10 and business logic flaws across whitebox, greybox, and blackbox modes with 90-day free re-testing, removing the friction of scheduling and paying for repeat assessments. Skip this if your team needs deep manual testing for complex threat modeling or custom attack scenarios; the AI agents excel at finding known vulnerability classes, not novel ones.
Penetration testers validating HTTP/2 cleartext smuggling exposure will find h2csmuggler indispensable because it's purpose-built for this specific attack vector rather than a generic proxy tool adapted for it. The 750 GitHub stars signal active community validation and ongoing refinement for real-world h2c implementations. Skip this if your scope is broader vulnerability scanning; h2csmuggler does one thing and demands you know enough about HTTP/2 protocol handling to interpret results effectively.
