What it sells: Filigran

What XTM Platform does[1][4][5][10][11][18]

What OpenCTI does[4][6][8][10][12][14]
OpenCTI offers 400+ one-click integrations and uses a consistent STIX 2.1 data model. It includes case management for incident-related data.
What OpenAEV does[2][4][9][10][12][15]
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.
What XTM One does[1][4][10][18]
XTM One 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.

What it sells: Kai

What Kai Autonomous Defense Platform does[4][13]
The Kai Autonomous Defense Platform executes the exposure lifecycle end to end without human handoffs. Kai aggregates findings from existing security and IT systems, determines reachability and exploitability, discards what cannot be exploited, attaches evidence to what survives, and then remediates. Kai agents interrogate CMDB, endpoint, cloud, identity, scanning, and code systems, then rebuild each asset record from the evidence they find.
What Continuous Threat Exposure Management (CTEM) does[7]
Kai runs all five phases, then adds two more: it executes the assigned fix immediately, and it watches exposed assets with targeted detection rules until remediated. Auto-remediation sits at phase six, where Kai takes immediate action once a fix is assigned.
What Kai Watch does[7]
Kai Watch continuously monitors telemetry to identify active exploitation. Kai Watch deploys validated detection rules to contain risk across the environment while fixes are in progress. Kai Watch is part of the detection phase, which Kai places at phase seven once remediation is underway.
What AI-native SAST does[15]
Kai is releasing an AI-native SAST capability in preview for select customers. Kai applies AI-native reachability analysis from the start, combining static analysis with runtime behavior to determine whether a finding is actually exploitable before it reaches a human. Kai validated each finding by automatically generating exploits and running them in an out-of-band non-production environment.

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]
