DeepSeas operates detection, tuning, investigation, and response inside your existing SIEM or provides a managed SIEM option with integrated context and analyst support.
Continuous monitoring, investigation, and response for endpoints and servers, with analyst-led judgment, threat context, and response actions within agreed authority.
Specialized monitoring for operational technology and industrial control environments, with response decisions aligned to plant safety, uptime, and engineering requirements.
Continuous attack-surface mapping, dark-web monitoring, vulnerability prioritization, and detection integration help reduce the exposures most likely to be exploited.
Network monitoring is most valuable when it contributes to one investigation instead of creating another disconnected alert queue. DeepSeas combines network telemetry with endpoint, identity, cloud, and email context to investigate the full path of an intrusion. This helps reveal threats involving contractor devices, legacy systems, industrial equipment, IoT, and other environments where endpoint coverage may be incomplete, while giving your team documented response outcomes.
