The challenge: AI speed and scale

Attacks got faster. The response didn’t.

The fastest eCrime breakout now takes 27 seconds, and attacks by AI‑powered adversaries rose 89% year over year.*

*CrowdStrike 2026 Global Threat Report

  1. You have minutes to respond.

  2. An alert alone doesn’t stop it.

  3. Sevii stops attacks at machine speed and scale.

Our mission: Helping the Cyber Good defeat Cyber Evil.

AI SOC is just the beginning.
Sevii built what’s next.

Autonomous cyber defense across your security stack.

Sevii’s modular ADR platform is the execution and control plane across the security and IT tools you already use. It turns detections and threat intelligence into governed investigation, hunting, containment, and remediation—at machine speed and scale.

Sevii’s platform is powered by Cyber Warriors that act autonomously to stop threats at machine speed and scale. No human-in-the-loop required.

Sevii’s Level 6 Autonomous Defense & Remediation (ADR) platform goes far beyond L1 and L2 triage. As Autonomous Cyber Defense, Sevii takes hunting and remediation further: preemptive learning, hypothesis hunts, and stopping known and unknown attacks.

Cyber Swarm Defense (CSD)

Cyber Swarm Defense generates as many Cyber Warriors as the threat volume requires, investigating and resolving threats in real time, without charging AI tokens.

AI governance

Sevii hunts and remediates under customer-defined AI governance—execution rules aligned to your organization’s policies.

Near-instant remediation

Measured at the edge, not from the moment a ticket is created.

How Sevii works

Detection to remediation in minutes.

InvestigationIdentityRemediationClose
01 · Detect

Alerts fire the moment a threat lands

Sevii processes every detection at the edge. Detections flow in by API from the tools you already run. No software on your endpoints.

02 · Hunt

We hunt everything.

Every hunt is autonomous: 7-day retrospective hunts, hypothesis hunts, and reverse engineering.

03 · Speed & Scale

Autonomous Defense That Scales With the Threat at Machine Speed

You set the SLO for how quickly attacks must be stopped. Cyber Swarm Defense deploys as many Cyber Warriors as the number of attacks requires, to stop threats at machine speed and scale.

04 · Remediate

Stop adversaries within your guardrails

Threats are remediated autonomously, under the AI governance policies you set.

05 · Report

Every action on the record

Every decision and action is documented, for full auditability.
