TAMPA, Fla. – June 16, 2022 – ReliaQuest, a force multiplier of security operations, today announced that it has joined the Microsoft Intelligent Security Association (MISA). MISA is an ecosystem of independent software vendors and managed security service providers that have integrated their solutions to better defend against a world of increasing threats.

“With digital transformation driving migration to Microsoft Azure, it becomes even more critical to have a unified view across an organization’s security infrastructure,” said Brian Foster, ReliaQuest Chief Product Officer. “Now, with added support for Microsoft Sentinel, Microsoft 365 and Microsoft Defender for Endpoint, ReliaQuest GreyMatter extends visibility across the Microsoft ecosystem. GreyMatter unifies detection, investigation and response to drive security effectiveness and cyber resilience, while allowing the customer to integrate Microsoft Security products at the pace that best suits their organization.”

This collaboration makes it easy for Microsoft customers – whether on premises or in one or more clouds – to ingest data and automate actions across any vendor solution. GreyMatter, coupled with deep security operations expertise, expedites threat detection and response. This drives greater effectiveness of existing investments including the correlation capabilities of Microsoft Sentinel and Microsoft Defender for Endpoint.

GreyMatter contextualizes threat research, collective customer intelligence, and over 40 open source and commercial security data feeds to create a comprehensive, actionable view of existing and emerging threats. ReliaQuest will continue to invest in GreyMatter’s capabilities to integrate with the Microsoft 365 security suite, furthering the ReliaQuest mission to “Make Security Possible.”
