Compare
OpenCTI is very good. Here is when it is not the right fit.
If you are one organisation building a threat knowledge graph, OpenCTI Community is an excellent choice and we interoperate with it. If you need to operate several isolated clients, collect your own intelligence and push enforcement, the comparison changes.

| OpenCTI (Filigran) | Wahukeza | |
|---|---|---|
| Best for | A single organisation that wants a strong open-source knowledge graph and a large connector ecosystem. | A provider or team that must operate several isolated tenants and turn intelligence into enforcement. |
| Multi-tenancy | No native multi-tenancy in OpenCTI; organisation segregation is an Enterprise Edition feature. One instance per client is the common workaround. | Database per tenant, control plane, per-tenant jobs, operator/admin separation: the architecture of the product, not an edition. Provider licensing is by arrangement. |
| SSO, audit log, segregation | Enterprise Edition. | MFA, scoped API keys and a hash-chained audit log in every package; OIDC SSO, SCIM 2.0 and custom permission sets are the Enterprise Identity module. Tenant segregation is a database per tenant. |
| First-party collection | None. Intelligence comes from connectors: OSINT, commercial vendors and user input. | A deception fabric of 17 device personas plus a capture engine that clones your own kit, Endpoint Intelligence, Phishing Reporting, edge sightings, and a ledger of what was new. |
| Enforcement output | Exports and integrations; enforcement is left to the connected tools. | Blocklists in EDL, Fortinet, Suricata, RPZ, nginx formats with ETag polling, plus sightings back. |
| Exposure validation | Via the sibling OpenAEV product, fed by the same third-party intelligence. | Adversary Emulation driven by what your own sensors observed; coverage-gap report tied to sessions. In Complete, or licensed on its own. |
| Standards | STIX 2.1 native, TAXII, MISP connector. | STIX 2.1-native model, TAXII 2.1 server and client, MISP feed both ways. We interoperate with OpenCTI. |
| Stack | Elasticsearch/OpenSearch, Redis, RabbitMQ, MinIO, plus workers. | Postgres 16, Redis, one API image. Compose or Helm. |
| AI | AI features available; provider options vary by edition. | Chosen at install: a local model, Anthropic with your own key, or off. Retrieval on Postgres full-text search. |
| Commercial | Community edition free; Enterprise Edition by quote. | Four packages, modules individually, unlimited analysts; quote after a scoping workshop. |
Straight answers
Choose OpenCTI when…
You are one team
No client tenants to isolate, no per-client reporting. The community edition is free and the ecosystem is large.
You want the biggest connector catalogue
OpenCTI’s connector ecosystem is broader than ours. We cover 40+ inputs, generic TAXII, MISP and CSV connectors included; they cover more.
You already run it
Keep it. Point its TAXII at us or ours at it. The two platforms speak the same standards.
Straight answers
Choose Wahukeza when…
Every client needs isolation
A database per tenant survives a compliance review; a filter on a shared index does not.
You want intelligence about your own perimeter
Sensors that look like your estate, telemetry from your endpoints, sightings from your firewalls, not only feeds.
The output has to be enforcement
Your firewalls and resolvers pull blocklists in their own formats and report what they blocked.
Seats should not be the meter
Unlimited analysts in every package, and the audit log is never an upgrade.
Run them side by side.
We will connect a reference deployment to your OpenCTI over TAXII and show what each does with the same bundle.
