DeepSeas examines endpoint, identity, network, cloud, email, and data telemetry for evidence of current or historical intrusion, then documents findings and immediate priorities.
Network telemetry helps surface lateral movement, command and control, data staging, and unmanaged devices that endpoint agents may not cover, adding context to the investigation.
A broader evaluation identifies security strengths, weaknesses, and prioritized risks through stakeholder interviews, asset inventory, risk workshops, and documented treatment planning.
A compromise assessment replaces assumptions with evidence. DeepSeas hunts across endpoint, identity, network, cloud, email, and data telemetry for persistence, unauthorized access, credential misuse, malware, and lateral movement. The engagement is especially useful during mergers and acquisitions, after an unexplained anomaly, following a peer or supplier breach, or when leadership, an insurer, regulator, or customer requires defensible assurance. Findings include what evidence exists, what it means, and what to do next.
Assessment findings help organizations understand exposure, prioritize action, and strengthen detection against future intrusion.
