Telemetry is collected from across your networks, endpoints, and cloud environments, analysed using the latest machine learning and behavioural detection engines, then enriched with the latest threat intelligence.

Detection & Enrichment

Detections are correlated and then grouped together by common attributes to create ‘cases’ – providing a more complete overview of security events.

Investigation & Hunting

Cases are triaged by our 24/7 Security Operations experts, using initial findings to hunt deeper before escalating those requiring additional attention to Kroll's elite incident response team.

Response & Containment

Automated response playbooks are enhanced with robust remediation to disrupt, contain, and eradicate threats before they cause costly damages.
