Because you can’t protect what you can’t see.

Managed Detection and Response (MDR) Services.

MDR that identifies and helps mitigate unmonitored infrastructure to provide the highest quality service.

Traditional MDR can’t confirm every asset is being monitored.

Proactive security intelligence ensures the SOC receives all expected data and telemetry to perform detection and response. It minimizes threat exposure and optimizes security operations, giving decision makers from SecOps to CISOs visibility and validation that:

Unmonitored assets are identified

Threat signals align with asset inventories and are received

Log sources are ingested

What makes Critical Start MDR different?

It’s MDR that starts before the first threat signal is received.  

Critical Start uses its transparent service delivery platform and MOBILESOC® application to integrate proactive security intelligence — such as comprehensive asset inventories, Endpoint Detection and Response (EDR) and Security Information and Event Management (SIEM) coverage gaps, asset criticality, and MITRE ATT&CK® Mitigations — with traditional, reactive threat detection and response for enhanced visibility that delivers the greatest risk reduction of a breach and minimizes business disruption.
