Meet the World’s First Level 5 Autonomous Defense & Remediation Platform

Sevii’s mission is to help Cyber Good defeat Cyber Evil. Selected for the 2026 CrowdStrike, AWS, and NVIDIA Cybersecurity Startup Accelerator, Sevii delivers the world’s first Level 5 Autonomous Defense & Remediation (ADR) platform, powered by governed agentic AI. With millions of enterprise assets and identities protected across commercial, government, and education environments, Sevii enables organizations to defend against modern adversaries at machine speed and scale.

As cyber threats become faster, more sophisticated, and increasingly powered by AI in the Mythos Era, traditional human-driven security operations struggle to respond at the speed required. Sevii moves organizations beyond human-speed investigation and response by providing an autonomous defense layer designed to operate across existing security environments.

Sevii’s autonomous AI Cyber Warriors investigate detections, hunt threats, reason, reverse engineer, isolate attacks, and execute full remediation across endpoint, identity, and cloud environments with humans in the loop optional. The Cyber Warrior workforce acts as a frictionless extension of security teams, performing L1–L3 analysis, threat hunting, and security engineering at machine speed. Unlike legacy tools that can create more “homework” for analysts through additional alerts, Sevii’s modular platform integrates with the existing security stack to autonomously investigate and remediate threats. Sevii can remove the adversary from the endpoint before a human analyst even opens the ticket.

Designed to operate across existing security stacks, Sevii complements and extends an organization’s existing cybersecurity investments rather than adding another silo. This approach enables organizations to introduce autonomous defense capabilities across their environments while reducing the operational burden placed on security and engineering teams.

By moving cybersecurity beyond human-speed investigation and response, Sevii helps organizations reduce operational risk and cost, maximize existing security investments, and strengthen their ability to defend against increasingly automated and AI-driven threats.
