Integrated incident response capabilities help organizations prepare for, investigate, contain, recover from, and learn from cyber incidents.

Incident Response

DeepSeas provides experienced responders for incident scoping, containment, remediation coordination, digital forensics, network analysis, malware analysis, threat hunting, and recovery.

Compromise Assessment

Experts examine endpoint, identity, network, cloud, email, and other telemetry for evidence of current or historical intrusion, persistence, credential misuse, and lateral movement.

Readiness Exercises

Tabletop exercises and mock incidents test response plans, decision rights, team coordination, evidence requirements, communications, and relationships with external response partners.

Response Without Guesswork

Experienced Support When Incidents Escalate

An incident response retainer gives your team access to experienced support when a suspected compromise demands immediate clarity and coordinated action. DeepSeas responders work within your tools and governance to investigate activity, preserve chain of custody, analyze malware and networks, coordinate containment, and guide recovery. Threat intelligence, indicator enrichment, and dark web research add context while findings become improved detections and response policies.

Frequently Asked Questions

What is the role of incident response in digital forensics?

Incident response uses digital forensics to determine what happened, how an attacker gained access, what systems or data were affected, and whether malicious activity remains. Forensic work can include evidence preservation, endpoint and network analysis, malware analysis, timeline development, and investigation of identity or cloud activity. The findings support containment and recovery while helping organizations maintain defensible records of the incident.
