Readiness Tabletop Exercises
DeepSeas runs realistic tabletop exercises and mock incidents to test response procedures, team coordination, escalation paths, and decision-making across technical and business groups.
Prepare your organization to respond decisively when a cyber incident occurs. DeepSeas evaluates response capabilities, tests coordination through realistic tabletop exercises, identifies gaps across technical and business teams, and helps develop practical playbooks, escalation paths, communication templates, and evidence procedures. With nearly 30 years of cyber defense experience, DeepSeas helps organizations replace uncertainty with measurable readiness and clearer decisions under pressure.
Assess readiness, test response coordination, investigate compromise, and strengthen the capabilities needed to manage cyber incidents.
DeepSeas runs realistic tabletop exercises and mock incidents to test response procedures, team coordination, escalation paths, and decision-making across technical and business groups.
Experienced responders support scoping, containment, remediation, recovery, digital forensics, network analysis, malware analysis, and threat hunting during an active incident.
DeepSeas examines endpoint, identity, network, cloud, and email telemetry for evidence of current or historical intrusion, persistence, credential misuse, and lateral movement.
A structured assessment identifies strengths, weaknesses, prioritized risks, control gaps, and practical treatment options through interviews, workshops, asset inventory, and documentation.
Controlled penetration tests and attack simulations help expose weaknesses in applications, infrastructure, and processes before real attackers discover them.
Continuous network visibility helps identify lateral movement, command and control, data staging, and unmanaged devices that endpoint agents may not cover.
Incident response readiness is more than having a document. DeepSeas evaluates who declares an incident, how teams escalate, what evidence is available, and whether legal, communications, leadership, and technical stakeholders can coordinate effectively. Exercises use realistic scenarios and produce prioritized improvements, including playbooks, decision rights, communication templates, retention requirements, and external relationships needed when an incident unfolds.
