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.
