Filigran

Filigran is a cybersecurity company founded in 2022 that builds the eXtended Threat Management (XTM) suite of open-source and enterprise products for cyber threat intelligence, adversary simulation, and crisis management. Its flagship OpenCTI platform exposes a full GraphQL API for structuring, storing, and disseminating STIX 2.1 threat-intelligence knowledge, while OpenAEV (formerly OpenBAS) provides a RESTful API for breach-and-attack simulation and adversarial exposure validation. Filigran maintains official Python clients (pycti, pyobas), a native embedded Model Context Protocol (MCP) server, TAXII 2.1 and SSE live-stream data sharing, webhooks, and a React component / design-system library. The company is SOC 2 Type 2 and ISO/IEC 27001:2022 certified and is backed by Accel and Insight Partners.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Filigran

Each block below is one kind of artifact we hold for Filigran. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 2

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Individual APIs this provider publishes, each with its own machine-readable definition.

OpenCTI GraphQL API

The OpenCTI platform exposes a full GraphQL API on the /graphql endpoint for programmatic access to cyber threat intelligence knowledge modeled on STIX 2.1. Authentication uses ...

OpenAEV REST API

OpenAEV (formerly OpenBAS) is an ISO 22398-aligned platform for planning and running crisis exercises, adversary simulations, and breach-and-attack simulation. It ships a RESTfu...

MCP Servers 1

Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

Event Specifications 1

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

Security Posture 2

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
