Critical Start MDR vs ReliaQuest MDR

Critical Start MDR is a managed detection and response service combining proactive security intelligence with human-driven threat detection and response. It identifies unmonitored assets, endpoint coverage gaps, and log-ingestion failures. Customers can choose automatic, facilitated, or managed remediation, while analyst collaboration and threat response are described as available 24x7x365. The MDR page states a 10-minute notification SLA for Critical alerts. Named integrations include CrowdStrike Falcon, Microsoft Defender for Endpoint, Palo Alto Networks Cortex XDR, SentinelOne, and VMware Carbon Black. The provider also describes direct APIs and more than 100 log-source integrations across email, identity, cloud, network, and endpoint environments. MOBILESOC, available on iOS and Android, can isolate hosts, disable user accounts, and remove email. Analysts work in SOC 2 Type 2 certified centers. MDR for operational technology supports multiple physical locations, separate IT and OT alert handling, and read-only visibility rules. Pricing is available on request.

ReliaQuest MDR is an outsourced security-operations service covering continuous monitoring, threat detection, investigation, and incident response. Its overview describes real-time 24/7 coverage, with providers able to hunt proactively for unknown threats. The service works with GreyMatter, an agentic AI security-operations platform for detection, containment, investigation, and response across cloud, hybrid, and on-premises technologies. GreyMatter connects with more than 300 technology partners, including SIEM, EDR, network-security, and cloud tools, and can unify connected sources without moving their data. ReliaQuest offers proof-of-value engagements with trial periods and success criteria agreed before work begins. GreyMatter pricing is per endpoint for the core platform, with additional capabilities priced by covered scope rather than token usage. ReliaQuest says log data is retained for 72 hours for investigations and 30 to 90 days for hunt campaigns, configured by the customer. Pricing is available on request.
