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]

The CyberFusion SOC emphasizes proactive threat hunting, engaging across different teams to stay ahead of potential threats. The CyberFusion SOC provides solutions based on client-specific needs, industry verticals and risk appetites. The CyberFusion SOC uses an integrated, cyclical model with interconnected components like threat intelligence, detection engineering and incident response. DeepSeas threat intelligence analysts study how adversaries operate and gather the data on the DeepSeas platform. DeepSeas has a team of reverse engineers, threat analysts and forensics experts that continuously strengthens its threat intelligence base. DeepSeas analysts write a new detection rule when a hypothesis is confirmed. DeepSeas validated findings become detection rules that deploy automatically across every monitored environment. DeepSeas describes threat hunting as active and human-led, with analysts searching for adversaries that never triggered an alert. DeepSeas turns proprietary and public sources of threat intelligence into tuned detection rules. DeepSeas sources threat intelligence from government, commercial and dark-web channels.[6][8][9]

DeepSeas combines real attacker tradecraft with manual validation to uncover the hidden attack paths automated testing often misses. DeepSeas offensive testers work across networks, apps, APIs, wireless, cloud, people and physical access. 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]

DeepSeas offers audit readiness and compliance support for SOC 2, ISO 27001, HIPAA, NIS2 and regulated industries. DeepSeas automated control mapping links controls to each standard, and continuous monitoring flags gaps as they surface. DeepSeas experts guide the fixes, get evidence in order, and stay through the external audit with advisory support. DeepSeas packages automated control mapping and evidence into auditor-ready reports. DeepSeas provides board-level guidance, security architecture and program design aligned with business risk.[11][12]

DeepSeas Complete starts with Endpoint MDR and puts 50+ services within reach, all under one agreement and one pool of credits. In DeepSeas Complete, Endpoint MDR is the only service a buyer has to buy, and everything else is optional. Every service in DeepSeas Complete runs on credits, which buyers purchase in blocks sized to their program.

Elective Credits can be applied across 50+ services, including security testing, assessments and advisory engagements. Elective Credits remain available throughout the contract term and carry between contract years on multi-year agreements. DeepSeas needs a user count to size the baseline for DeepSeas Complete, and deployment begins on signature.[1][2][5][7][9][10][12][13]
