CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Teams under 50 people running alert overload on existing ticketing systems should start with Catalyst; it's the only free SOAR that actually closes the loop between your alerts and your incident response without forcing you to rip out Jira or ServiceNow. The 519 GitHub stars and zero pricing barrier mean you can pilot playbook automation without budget justification. Skip this if you need enterprise integrations with premium EDR platforms or multi-tenant role-based access; Catalyst prioritizes speed over breadth and will feel thin once you scale past your first few playbooks.
Security teams drowning in alert volume need Radiant Agentic AI because its AI triage actually closes the investigation loop with one-click executable response, not just prioritization theater. The platform covers 100 percent of alerts across email, endpoint, identity, network, and cloud with full reasoning transparency, so you're not trusting a black box to kill your incidents. Skip this if your organization needs heavy forensics and recovery workflows; Radiant prioritizes speed through detection and mitigation over the deep post-incident analysis required for complex breach investigations.
