D3 Security (Morpheus)

D3 Morpheus is an autonomous AI SOC platform from D3 Security, the established SOAR vendor behind Smart SOAR. Morpheus investigates and responds to security alerts without human intervention for routine work: it ingests alerts from the entire security stack, performs full L2-depth Attack Path Discovery on every alert, generates a bespoke response playbook at runtime, and delivers a structured case file ready for analyst review, all in under two minutes, with up to 95% of alerts triaged and L2-investigated in that window. Attack Path Discovery hunts horizontally across identities, endpoints, cloud, and email (lateral movement) and vertically through time (privilege escalation, persistence), reconstructing the complete attack path rather than examining alerts in isolation. Underneath sits the Cybersecurity Triage Reasoning Graph, a domain-specific reasoning architecture encoding how a senior SOC analyst reasons: nodes are security entities and concepts, edges are reasoning patterns, and the graph constrains what the LLM considers at every step so it never reasons about irrelevant telemetry. D3 explicitly positions this unified-engine design against multi-agent platforms (Torq, Dropzone, Prophet, CrowdStrike), arguing message-bus coordination fragments context and audit trails; Morpheus instead runs bounded agentic reasoning inside one deterministic playbook with explicit iteration, cost, tool-scope, and approval-gate bounds. Six capabilities (triage, investigation, response and orchestration, self-healing integrations, agentic task, autonomy modes) run on one reasoning engine producing one unified audit trail per incident, designed to read identically to a US examiner, an EU supervisor, or a critical-infrastructure regulator, with accountability framed under SEC, NYDFS, NIS2, DORA, and the EU AI Act. Autonomy modes provide graduated autonomy with remediation recommendations routed to analysts for approval. D3 continuously tests Morpheus against simulated attacks and adversarial inputs, publishing an 87% attack path revelation rate and 94% investigation closure rate. Deployment runs on Azure with four-region data residency and on-premises for regulated industries. Sold as an annual platform subscription sized to the SOC with an included envelope of AI investigations, and a strong MSSP channel for MDR/MXDR delivery. Morpheus is the lane's SOAR-incumbent-gone-AI-SOC entrant and its compliance-architecture benchmark.
