D3 Security develops security orchestration, automation and response (SOAR) platforms for security operations centers. The company's flagship product, Smart SOAR, combines incident response automation with alert management capabilities. The platform includes the Event Pipeline, which processes incoming security alerts through de-duplication, enrichment, correlation and normalization to reduce alert volume. D3 Security provides codeless playbook editors, vendor-maintained integrations with security tools, and three levels of automation covering alerts, incidents, and scheduled tasks. The platform incorporates NIST and SANS-based playbook libraries, MITRE ATT&CK TTP tracking, and MITRE D3FEND-based playbooks and automations. The company integrates with SIEM platforms, threat intelligence platforms, and other security tools. In 2024, D3 Security introduced Morpheus, an AI-powered capability that provides automated triage and response, AI-generated incident summaries, and prompt-based playbook generation. The company participated in the Microsoft Security Copilot Partner Private Preview program. D3 Security serves enterprises, government organizations, and managed security service providers (MSSPs). Clients include financial institutions, stock exchanges, and large corporations operating security operations at scale. The company was founded in 2015 and focuses on reducing manual work for security analysts through automation of repetitive security operations tasks.
