CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams building custom threat hunting workflows on a budget should evaluate Bearded Avenger for its lightweight integration approach and free pricing model that eliminates vendor lock-in. The 183 GitHub stars and active integration ecosystem suggest real adoption among practitioners who value flexibility over UI polish. Skip this if your team needs managed threat hunting services or turnkey alerting; Bearded Avenger demands engineering time to extract value.
Mid-market and enterprise security teams drowning in disconnected threat feeds will get the most from Filigran OpenCTI because its hypergraph architecture actually makes intelligence actionable instead of just stored. The 300+ integrations and STIX 2.1 data model mean you can ingest everything from your vendor ecosystem and surface signals that stay buried in spreadsheets elsewhere, with case management that ties intelligence directly to incident response. Skip this if you need a fully managed, point-and-click platform; OpenCTI demands some operational maturity to deploy and configure properly, and the open-source licensing model appeals to teams comfortable with self-hosted infrastructure.
