What DeepSeas does
DeepSeas is a managed security services provider (MSSP) delivering a six-pillar cybersecurity platform — Managed Detection and Response (MDR), Offensive Security (DeepSeas RED), Threat Intelligence, Governance/Risk/Compliance (GRC), CyberFusion SOC, and Strategic Security Advisory (vCISO) — consolidated under the flagship DeepSeas Complete bundle that contracts all services through one program with one dedicated advisor team. The platform operates in a vendor-agnostic model, integrating with customers' existing Splunk/Sentinel SIEMs, EDR platforms, CNAPP solutions, identity, firewall, and OT/ICS tools without rip-and-replace, while proprietary threat intelligence generated by in-house reverse engineers feeds environment-specific custom detection rules that auto-deploy across all monitored environments via the CyberFusion SOC loop. AI/ML is applied to behavioral analysis, false-positive reduction, and automated detection-rule generation, with senior analysts validating surfaced alerts before customer delivery.
The company serves approximately 1,000 clients globally spanning Fortune 100 enterprises, mid-market organizations, healthcare, higher education, SLED, financial services, manufacturing, and life sciences — environments where IT/OT convergence, regulatory complexity (HIPAA, GLBA, SOX, CMMC, PCI DSS, NIS2), and lean security teams drive demand for outsourced full-stack coverage. Revenue is generated primarily through annual recurring managed-service subscriptions and professional services engagements (penetration testing, vCISO advisory, compromise assessments), with go-to-market executed via enterprise field sales, an MSSP/MSP partner portal, and self-serve MDR deployment. DeepSeas was formed in December 2022 by uniting Booz Allen Hamilton's commercial managed threat services business with Security On-Demand, subsequently executing three acquisitions within twelve months (RedTeam Security, GreyCastle Security) and being recognized by Frost & Sullivan as a Top 5 MDR provider in 2025 and recipient of the 2026 MDR Technology Innovation Leadership Award.
