Critical Start MDR Services is a managed detection and response offering that combines proactive security intelligence with traditional threat detection and response. The service begins before the first threat signal is received by identifying unmonitored assets, endpoint coverage gaps, and log ingestion failures to ensure the SOC receives all expected data and telemetry. Key components include: - Complete Signal Coverage: Identifies hidden and unmanaged assets, endpoint (EDR) and SIEM coverage gaps, and log source ingestion failures. - Flexible Deployment: Supports IT and OT environments with tailored response strategies across email, identity, cloud, network, and endpoint environments via direct APIs and 100+ log source integrations. - Human-Led Investigation: 24x7x365 access to security analysts for contextual threat analysis and incident collaboration. - CORR Platform: A transparent service delivery platform providing real-time, actionable visibility into active threats. - MOBILE SOC® App: iOS and Android application enabling analysts and customers to action incidents on the go, including host isolation, disabling user accounts, and email removal. - Trusted Behavior Registry® (TBR®): Auto-resolves false positives to reduce alert fatigue. - MITRE ATT&CK® Mitigations: Maps detections and response actions to MITRE ATT&CK framework to improve security posture. - Service Level Agreements: Contractual SLAs with 10-minute notification for Critical alerts. Deployment scenarios include coverage for the Microsoft Security suite (TDIR), Managed XDR without requiring a customer-owned SIEM, and Security Services for existing SIEM investments.
