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.
Network engineers and security testers who need to validate IDS/IPS signatures or stress-test firewalls will find Tcpreplay invaluable because it lets you replay real pcap files at line rate without touching production traffic. The tool is free, actively maintained on GitHub with 1,308 stars, and handles the packet-level precision that commercial replay tools charge thousands for. Skip this if you need GUI-driven scenario building or support for encrypted traffic manipulation; Tcpreplay is command-line only and works best when you already have clean packet captures to work from.
