Kai emerged from stealth on March 10, 2026 with $125 million in funding, led by Evolution Equity Partners with participation from N47 and strategic investors. On July 29, 2026, Kai announced findings from its 2026 State of Autonomous Defense Report and made its Auto Remediation capability available. Kai says it has delivered autonomous security work for Fortune 500 and Global 1000 enterprises across multiple verticals.

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.

What it sells: Mate Security

What Gamebooks does[4][14]
A Gamebook is Mate's investigation process, built for AI agents. Mate migrates existing SOAR playbooks into agentic procedures designed for AI-scale attacks. Mate ships Gamebooks for core investigation domains. A customized Gamebook runs through Mate's evals and tests before it goes live.
What Security Context Graph does[13]
Mate's Security Context Graph continuously maps an organization's architecture, crown jewels, exposures, activity and relationships, giving Hunt Agents the context to understand where risk is highest. Mate captures why an analyst made a call, not just the final verdict.
What Agentic Threat Hunting does[13]
Mate extracts IOCs and TTPs, then hunts across every connected tool. Agentic threat hunting prioritizes where to hunt and follows evidence across connected tools as the investigation develops.

About Kai

Kai is an AI company that sells the Kai Autonomous Defense Platform, an agentic AI platform for cyber asset management, application security, infrastructure vulnerability management, and detection engineering. Kai says its platform is an agentic AI platform built from first principles to do security work end-to-end: gathering exhaustive context, continuously assessing risk, prioritizing action, and reducing risk. Kai describes a single agentic AI platform that does the actual security work autonomously and continuously across threat intelligence, exposure management, detection, response and beyond. Kai says its platform continuously analyzes threat intelligence, vulnerabilities, asset context, and other sources, correlates risk across the environment in real time, and can execute remediation actions.[1][6][13][14]

Kai says AI-enabled attacks arrive faster and in volumes no queue can absorb. Kai says each step of the response belongs to a different tool and team, so the exposure waits at every handoff. Kai describes a gap in which an exposure is confirmed as real and then sits exposed while a team works out how to fix it. Kai describes approved fixes that wait in a ticket queue instead of shipping. Kai says it runs every step on one platform at machine speed. Kai describes its auto-remediation as validating before acting and showing its work at every step.[4][7]

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 remediates by writing the change, routing it to the accountable owner, or deploying a compensating detection when a patch is blocked. Kai agents interrogate CMDB, endpoint, cloud, identity, scanning, and code systems, then rebuild each asset record from the evidence they find. Kai writes the change itself and, where a maintenance window blocks the patch, specifies the configuration change to the controls the customer already runs. Kai says some fixes wait on a maintenance window, a vendor patch, or a release, and the exposure stays open the whole time. Kai says it builds detection for the customer environment.[4][9]

Kai says Continuous Threat Exposure Management (CTEM) promised a repeatable path from exposure to fix: scope, discover, prioritize, validate, mobilize. 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 instead of letting it wait in a queue. Kai executes an assigned fix directly for the majority of confirmed findings. For the complex few findings that need human review, Kai builds the complete remediation plan, identifies the right owner, and stages it for approval. Kai Watch continuously monitors telemetry to identify active exploitation and deploys validated detection rules to contain risk across the environment while fixes are in progress.[4][7]

Kai determines which vulnerabilities are truly reachable and exploitable, then uses AI-native prioritization to rank them by actual risk. While remediation is underway, Kai creates and deploys detection rules to identify exploitation attempts in real time. Kai is releasing an AI-native SAST capability in preview for select customers. In its SAST capability, 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.[10][15]

Kai was founded by the creators of the category-defining companies Claroty and SecurityMatters. Galina Antova and Dr. Damiano Bolzoni previously built Claroty and SecurityMatters. Kai emerged from stealth with $125 million in funding. Kai says dozens of design partners iterated with it until the vision became something real. Kai says it has delivered autonomous security work across multiple use cases for Fortune 500 and Global 1000 enterprises across multiple verticals. Kai announced the appointment of Alfredo Hickman as Chief Information Security Officer. Kai Cyber Inc. lists its address as 90 Skyport Drive, Suite 200, San Jose, CA 95110.[1][2][4][6][7][9][10][13][14]
