CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams tasked with detecting data leaks across dark web forums, paste sites, and internal chat logs will find AIL Framework's modular architecture uniquely suited to that job; it ingests unstructured text sources most commercial threat intel platforms ignore entirely. The framework processes data correlation natively without forcing you into a vendor's proprietary schema, and it's free, which matters when you're running analysis at scale across dozens of data feeds. Skip this if you need UI polish, guided workflows, or vendor support; AIL rewards teams comfortable building custom extraction rules and debugging Python integrations.
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.
