An OpenCTI alternative that arrives ready-tailored.
OpenCTI is a powerful threat intelligence platform, open-source with a commercial Enterprise Edition and a managed option. If you would rather not model a knowledge base and shape the platform yourself, and want intelligence that is tailored to each organisation from the start, here is how Liberty91 compares.
Start Free TrialWhat OpenCTI is good at.
OpenCTI is the most widely adopted threat intelligence platform of its kind, and for good reason. Its STIX 2 knowledge model, GraphQL API, and large connector ecosystem make it a strong framework for structuring, storing, and correlating intelligence. Alongside the free Community Edition, Filigran offers a commercial Enterprise Edition that adds agentic automation, AI-assisted reporting, Intelligence Requirements, multi-organisation data segregation, and dedicated support, available self-hosted, air-gapped, or as a fully managed SaaS.
For a team that wants to model its own knowledge base, own its data and stack, and extend an open platform, OpenCTI is an excellent choice in either edition. The thing to weigh is how much you want to shape and run yourself, against having a service that is tailored to each organisation from the start.
At a glance.
A fair, side-by-side read of where each one puts its emphasis.
| OpenCTI | Liberty91 | |
|---|---|---|
| Primary focus | A threat intelligence platform built on a STIX 2 knowledge model, for structuring, storing, and correlating CTI, with open-source and commercial editions. | A threat intelligence service that arrives pre-tailored per organisation and produces finished, bespoke reporting and detection content. |
| Editions and hosting | Free open-source Community Edition, plus a commercial Enterprise Edition, available self-hosted, air-gapped, or as a fully managed SaaS from Filigran. | A managed cloud service. Nothing to host, and each organisation is set up by sector and region rather than modelled from a blank instance. |
| Setup model | Your team models the knowledge base, configures connectors and playbooks, and shapes the platform to how you work. | Each organisation gets self-maintaining Intelligence Requirements derived from its profile, so the tailoring is there from day one and stays current. |
| Production | A platform your analysts produce intelligence on, with Enterprise Edition adding agentic automation and AI-assisted reporting. | Finished reports per organisation, surfaced, prioritised, and drafted in real time, plus IOC, Sigma, and STIX, ready for your analysts to review and send. |
| MSSP and white-label | Multi-organisation data segregation in the Enterprise Edition, positioned for MSSP deployments. | Multi-tenant with white-label across the sender, email templates, and report PDFs, priced per customer. |
| Where it shines | Control, data ownership, an open and extensible framework, and a large connector ecosystem. | A bespoke, per-organisation service that needs little modelling, delivered under your brand, and accessible to mid-market budgets. |
Where Liberty91 is different.
A service, not a platform to model
OpenCTI is a powerful framework your team populates, whether self-hosted or managed. Liberty91 takes a different shape: each organisation is set up by sector and region and given self-maintaining Intelligence Requirements derived from its profile, so the tailoring is there from the start rather than something you build into a blank instance.
Finished, bespoke reporting per organisation
Both can produce intelligence, and OpenCTI's Enterprise Edition adds AI-assisted reporting. The difference is the default: Liberty91 produces finished reports tailored to each organisation, surfaced, prioritised, and drafted in real time, with IOC lists, Sigma rules, and STIX bundles attached, ready for an analyst to review and send.
A force multiplier for your analysts
Liberty91 does not remove the analyst, it amplifies them. The collection, triage, and first-draft production run at machine speed, so the same team covers far more ground, faster and with fewer slips, and the analyst spends their time on judgement and direction rather than plumbing. You stay in control of the intelligence; the platform handles the repetitive collection and formatting.
White-label delivery for MSSPs
Run it across a whole customer base under your own brand. White-label the sender, the email templates, and the report PDFs, and prove delivery per customer through Mailroom's auditable Sent log.
When Liberty91 is likely the better fit.
Liberty91 tends to be the stronger choice when you want intelligence that is tailored to each organisation from the start and delivered as finished reporting, rather than a platform to model and shape. That suits MSSPs delivering a tailored service to many customers under their own brand, and teams that want relevant reporting mapped to their assets and suppliers without building out a knowledge base first.
If control, data ownership, and the freedom to model and extend an open framework matter most to you, OpenCTI is built for exactly that, in either edition. The decision comes down to whether you want a platform you shape and operate, or a service that arrives ready to tailor and amplifies the analysts you have.
