About DeepSeas

DeepSeas sells cybersecurity services that range from strategic guidance to offensive testing and 24/7 defense, aimed at lean teams protecting complex environments. DeepSeas Complete is a cyber defense program built on Endpoint MDR. DeepSeas Complete combines Vulnerability Management, Penetration Testing, Managed SIEM, Endpoint MDR, Threat Intelligence and a dedicated Strategic Advisor into one security program.[1][3][5][6][8][10]

DeepSeas offers 24/7 MDR for growing organizations with mixed environments, operated by lean security teams on the stack they already own. DeepSeas MDR is one service across IT, cloud, identity, mobile devices and OT environments, including production floors and medical systems. DeepSeas states that it is vendor agnostic: when a customer already runs an EDR or SIEM, DeepSeas operates and tunes it, and when a customer does not, DeepSeas brings its own. DeepSeas MDR begins monitoring in about two weeks, depending on environment complexity. DeepSeas contains threats on the customer's behalf, or gives the customer's team clear steps to handle them. DeepSeas MDR can optionally isolate a host or lock an account, on pre-approved playbooks. DeepSeas continuously tunes detection rules, uses AI to refine alerts, and has analysts validate what matters before it reaches the customer. Detections and alerts come together in the DeepSeas platform, a single place to view security operations.[1][7][12]

DeepSeas states that its testers are continuously certified, with certifications such as OSCP, OSCE and OSWP. DeepSeas tests by hand to cut false positives and catch what automation misses.[10]
