About Filigran

Filigran sells the XTM Platform, an eXtended Threat Management suite in which threat intelligence, adversarial exposure validation and agentic AI orchestration work together in one threat-informed defense loop, open source at the core.[1][4][5]

Filigran describes the XTM Platform as making continuous threat exposure management (CTEM) agentic. The suite is made up of OpenCTI, OpenAEV and XTM One, which work as one continuous loop, from anticipation to response. OpenCTI and OpenAEV are developed in the open with a 7,000+ member community.[4]

OpenCTI is an open-source platform to organize, analyze and operationalize cyber threat intelligence. OpenCTI offers 400+ one-click integrations and standardizes threat intelligence using a consistent STIX 2.1 data model. It includes case management for incident-related data.[4][8]

OpenAEV covers adversarial exposure validation: real attack simulation, autonomous pentesting and tabletop exercises. OpenAEV maps breach and attack simulation scenarios to MITRE ATT&CK and ATLAS. It can be deployed with or without an endpoint agent, across cloud, on-prem or multi-tenant setups.[9]

XTM One is the agentic AI layer that consolidates and orchestrates all assistive and agentic AI capabilities across the XTM platform. Customers can build their own agents and bring their own LLMs. CTEM Assistant is the primary entry point of the XTM Platform, with direct access to both OpenCTI and OpenAEV. OpenCRQ is described as coming soon, as the third open-source module of the XTM Platform, and it runs on a customer's own security data to quantify cyber risk.[1][10][11]

Filigran also sells services around the suite. Filigran provides fully managed cloud private instances for every product in the XTM suite, with each SaaS instance running in its own infrastructure tenant. SaaS pricing is based only on the resources available for the tenant, not on the number of users or integrations. Standard and premium support carry a guaranteed time frame for requests, and the customer success team is 100% in-house. Filigran Academy offers training paths for OpenCTI and OpenAEV, and a partner network of certified MSSPs, solutions providers and technology alliances deploys and operates Filigran platforms in a customer's region.[4][5][7][8][9][11][12][14][15]
