The right incident management tools depend on your environment, operating model, and response objectives. Common capability categories include managed detection and response, SIEM-based monitoring, endpoint detection and response, incident response case management, and tabletop or readiness platforms. DeepSeas supports these functions through integrated monitoring, investigation, response, threat hunting, existing-tool integrations, and readiness exercises rather than treating each alert source as a separate workflow.
