ReliaQuest
ReliaQuest helps enterprises consolidate security alerts and automate threat response.
ReliaQuest's GreyMatter platform is an XDR-based security operations platform that consolidates alerts and telemetry from siloed security tools (SIEM, EDR, IDS, cloud, antivirus, firewall) into a single normalized view without requiring a data lake. The platform uses AI and automation to reduce duplicate alerts by 41-43% and enables automated threat containment within 5 minutes of detection. GreyMatter Discover, launched October 2025, unifies asset data across security and cloud tools to surface exposures and enable immediate action.
Problem solved
Security teams waste analyst time managing duplicate alerts from multiple SIEM, EDR, and cloud tools instead of focusing on actual threats.
Target customer
Enterprise security teams managing complex hybrid and multi-cloud environments with multiple siloed security tools; particularly billion-dollar companies and mid-to-large enterprises requiring centralized security operations.

The October 2025 launch of GreyMatter Discover and April 2025 $500M Series E signal major momentum in AI-driven security operations automation, positioning the company as a critical infrastructure layer for enterprise security amid rising alert fatigue and tool sprawl.
Best for: Large enterprises with complex hybrid cloud environments and multiple security tools who need to reduce alert fatigue and automate incident response.
Use cases
Alert Consolidation & Deduplication
Security teams running SIEM, EDR, and cloud-native tools receive duplicate alerts across platforms. GreyMatter ingests and normalizes these alerts without a data lake, reducing duplicate SIEM alerts by 41% and EDR alerts by 43%, freeing analysts to focus on actual threats.
Automated Threat Containment
When a threat is detected across multiple tools, manual coordination between systems delays response. GreyMatter applies AI and automation to detect and containment within 5 minutes, significantly reducing dwell time.
Asset & Exposure Discovery
Security teams struggle to maintain accurate asset inventory across SIEM, EDR, IAM, cloud, and vulnerability scanners. GreyMatter Discover automatically finds, deduplicates, and unifies assets and identities, enabling immediate visibility into exposures.
Alternatives
