DeepSeas Complete combines managed detection and response, offensive security, threat intelligence, advisory, and GRC across IT, cloud, OT/ICS, and mobile/BYOD environments.
Endpoint MDR provides continuous monitoring, investigation, and response for endpoints and servers while working inside the endpoint tools your organization already uses.
Network Detection & Response adds visibility into traffic, lateral movement, command and control, data staging, and unmanaged devices that endpoint agents may not cover.
Mobile cyber security is most effective when device, identity, network, cloud, and email activity are investigated together rather than placed into separate queues. DeepSeas supports organizations with integrated monitoring and response across mobile and BYOD environments, using the tools they already own where appropriate. The result is clearer context around suspicious access, compromised accounts, unmanaged devices, and attack paths that isolated mobile controls may miss.
