About D3 Security

D3 Security sells Morpheus, an agentic SOC platform. Morpheus triages, investigates and responds across the full alert lifecycle, with every verdict graded by its evidence and every step on one traceable record. Morpheus defers to a human when it is uncertain. Morpheus includes the AI in its price rather than charging on a meter. D3 Security states that it is independent and profitable, has been in cybersecurity since 2012 and built Morpheus from scratch. D3 Security launched its SOAR in 2014.[1][4]

Morpheus grades every finding by evidence quality: Confirmed, Inferred, or Gap. When Morpheus cannot confirm a finding, Morpheus grades it Gap and hands the alert to an analyst. The Cybersecurity Triage Reasoning Graph classifies each alert, scores confidence and decides whether the alert warrants a full investigation. Attack Path Discovery is D3 Security's investigation engine and traces every alert across identities, endpoints, cloud and email infrastructure. Attack Path Discovery maps blast radius, validates IOCs and drafts remediation before an analyst opens the case. When incident response opens a Morpheus case, the case already carries a verdict, evidence, MITRE mapping and a drafted response plan. Adaptive Tasking is a conversational copilot inside every Morpheus case. Adaptive Tasking is grounded in the case's evidence and can dispatch agents to gather more intel from any of the 800+ integrations. Morpheus vulnerability triage applies the same investigation engine to scanner and AI-discovered findings.[1][5][9]

Morpheus offers four autonomy modes, Deterministic, AI-Assisted, AI-Led and Autonomous, on one engine with one audit trail, chosen per use case and changed by configuration. In one Morpheus mode, Morpheus investigates and proposes, and the analyst approves every state-changing action such as host isolation, account suspension or IP block. Morpheus response actions flow through 800+ self-healing integrations, including host isolation, account suspension, mailbox purge and ticket creation.[5]

Morpheus includes deterministic playbooks, 800+ self-healing integrations, integrated case management and a full audit trail per incident. The deterministic playbook engine in Morpheus offers drag-and-drop authoring, version control, YAML export and GitHub versioning. Morpheus connectors cover SIEM, EDR, IAM, cloud, email security, NDR, threat intel and ITSM platforms. Morpheus monitors every connector across every tenant and generates corrective code autonomously when drift is detected. Morpheus reads the detections a customer already has, investigates across the identity, endpoint, email, network and cloud tools the customer already owns, and writes the result back to the existing system of record where the integration supports it.[4][6]

Case management in Morpheus keeps one incident record across triage, investigation, response and evidence. Morpheus case management includes incident timeline, evidence preservation, custody chain, analyst notes, SLA tracking and regulator-ready exports. Morpheus writes every playbook step, analyst approval, integration call and command outcome to a single audit trail per incident. Morpheus maps its audit trail to SEC Item 1.05, NYDFS 500, HIPAA, NERC CIP, NIS2, DORA and the EU AI Act.[4]

Smart SOAR gives security teams automation and orchestration to offload manual processes, spot real incidents and trigger actions. Smart SOAR connects tools through REST API and vendor-agnostic integrations and automates workflows without coding. Smart SOAR enriches security events with threat intelligence including indicator, actor, digital risk, fraud, industry and service data. Smart SOAR lets teams configure and test integrations and playbooks from a single screen. Analysts opening an alert in Smart SOAR see incident types, playbooks, linked events, IOCs, logs and data from threat intelligence, incident knowledge and MITRE ATT&CK TTPs. Smart SOAR custom dashboards compare metrics such as MTTR, MTTD, number of incidents by type and open and close tickets by analyst against predetermined benchmarks. Smart SOAR provides customized compliance reporting for GDPR, HIPAA and 23 NYCRR 500.[7][8]

D3 Security states that Morpheus is built for Fortune 500 SOCs and the largest MSSPs. Morpheus is a multi-tenant agentic SOC platform for MSSPs and MDR providers. For service providers, Morpheus runs L1 and L2 investigation end to end on every client's alerts, grades every verdict by its evidence and executes response on deterministic playbooks with hard guardrails. In Morpheus, autonomy is set per client and tenant data stays sealed, including from the AI. Morpheus gives each tenant its own data partition, credentials, playbooks and audit trail, and scopes the AI's context to that tenant. Morpheus invokes no AI inference for tenants set to Deterministic. Morpheus tenants can be placed in Azure regions in the US, Canada, Ireland and Japan, on-premises, or air-gapped. Morpheus drafts client-specific playbooks from the client's connected stack and the provider's SOPs, the provider's team reviews and approves them, and a deterministic engine executes what was approved.[9]

Banks and major financial organizations use Morpheus to investigate alerts, build audit ready case records and track cases across cyber, fraud, privacy and corporate security teams. Morpheus runs Tier 1 and Tier 2 investigations across identity, endpoint, email and cloud signals. Morpheus investigates across IT, OT and physical signals and builds case records. Morpheus triages and investigates routine alerts and escalates the cases that need human judgment.[4][5][7][10]
