What is incident response?
Incident response is the structured process a security team follows when a confirmed security incident is identified, containing the threat, eradicating the adversary, recovering affected systems, and learning from the event to prevent recurrence.
Updated 2026-05-19
The standard incident response lifecycle (NIST SP 800-61) has six phases: preparation, identification, containment, eradication, recovery, and lessons learned. Larger organizations maintain dedicated CSIRT (Computer Security Incident Response Team) functions; smaller organizations engage external IR firms. The pressure on IR is high: every minute the adversary remains active increases damage. Documentation, evidence preservation, and legal coordination are non-negotiable.
How Command Zero handles Incident Response.
During an active incident, Command Zero accelerates the work of scoping the attack, answering "what was accessed", "which accounts were affected", "what data left the environment", "how did the adversary get in", by running expert investigation questions in parallel across all data sources. The investigation audit trail produced by Governed AI doubles as evidence preservation. Customers cite Command Zero specifically for breach scoping under pressure: hours of manual cross-source correlation become minutes of guided investigation.
