Out-of-band incident response for Microsoft-centric environments
Maintain operational continuity during global infrastructure incidents and public internet disruptions with a dedicated out-of-band instance for secure incident response. Integrate with Microsoft Security Suite and Entra ID to preserve centralized identity management while keeping sensitive data in an isolated system to enable rapid and resilient response.
