Endpoint MDR monitors endpoints and servers, investigates alerts, enriches cases with artifact and indicator context, and supports containment or account actions within agreed response authority.
Network Detection and Response adds visibility into lateral movement, command and control, data staging, and unmanaged devices that endpoint agents may not cover.
Managed SIEM services operate detection, tuning, investigation, and response inside an existing SIEM or provide SIEM capabilities with ingestion and storage included.
Email Threat Detection and Response identifies phishing, business email compromise, malicious links, attachments, and account takeover activity, then coordinates investigation and response.
OT and ICS Security Monitoring connects analysts with industrial environments, validating detections and response playbooks against operational constraints and safety considerations.
DeepSeas MDR works inside the security tools you already own, correlating telemetry across endpoint, network, cloud, identity, email, SaaS, and OT environments. AI filters and triages routine events, while analysts investigate complex activity, continuously hunt for threats, and tune detection logic to your environment and industry. You define response authority, and every action is documented for review by your team, board, auditor, or insurer.
