Sevii

Sevii provides an Autonomous Defense & Remediation (ADR) platform that uses agentic AI "Cyber Warriors" to investigate, contain, and remediate cyber threats in real time without human intervention. The platform integrates with existing security stacks, including endpoint, identity, and cloud tools, and its new Autonomous Preemptive Security (APS) module proactively hunts for vulnerabilities based on external threat intelligence. Sevii reports saving customers over $42 million in security operations costs and recovering more than 126,000 hours of security team time.

Problem

Security operations teams are overwhelmed by the volume of alerts and the speed at which adversaries, now powered by AI, can discover and exploit vulnerabilities. Traditional detection tools generate alerts that require manual investigation and response, leaving organizations vulnerable to attacks that outpace human reaction times and creating a significant workload burden on security analysts.

Solution

Sevii offers an Autonomous Defense & Remediation (ADR) platform that uses agentic AI "Cyber Warriors" to autonomously investigate, contain, and remediate threats in real time, without requiring humans in the loop. The platform sits above a customer's existing security technologies, using only the necessary tools and telemetry to execute a cyber mission. Its new Autonomous Preemptive Security (APS) module continuously transforms external and internal threat intelligence into autonomous hypothesis hunting, exposure validation, and remediation to preempt attacks. All actions are governed by a customer-defined AI control policy engine, ensuring full auditability and alignment with organizational risk tolerance.

Target Audience

Primary customers are enterprise, government, and education organizations with large security operations teams that need to reduce alert fatigue and accelerate response times across complex, existing security infrastructures.

Features

  • Fully autonomous threat hunting, investigation, containment, and remediation with no human-in-the-loop required
  • Autonomous Preemptive Security (APS) module that ingests and prioritizes external threat intelligence from commercial, ISAC, partner, and open-source feeds to proactively hunt for vulnerabilities and compromises
  • Specialized agent classes, including G2 for intelligence correlation and risk prioritization, and Jäger HK for executing enterprise-wide hypothesis hunts across endpoint, identity, cloud, and network platforms
  • AI Security module that operationalizes detections from AI Detection and Response (AIDR) tools, autonomously processing findings, hunting for related compromise, and validating remediation outcomes
  • Platform governance and control engine that coordinates all actions and provides full auditability of every decision
  • Integration with existing security stacks, including SIEM, cloud, identity, and endpoint tools, to execute remediation actions
