Material Security

Overview

Material Security protects Google Workspace and Microsoft 365 through APIs, treating email as one part of a broader cloud-workspace security problem^[18]. Its inbound email security targets phishing, social engineering and business email compromise. Beyond the inbox, an OAuth Remediation Agent shows what authorised third-party apps and AI agents do with their access and lets administrators revoke it; a Drive Agent finds over-shared sensitive files and remediates them in bulk; and account-takeover containment redacts sensitive historical messages and applies message-level access controls so that stolen credentials expose less data^[18]. Posture management covers tenant configuration. Customers named on the home page include Mars, Lyft, Figma, Reddit, OpenAI, Anthropic, Datadog and PagerDuty^[18]. Material’s distinctive idea is limiting the damage of a compromised mailbox rather than only filtering inbound mail. Its home page gives no founding details or prices, and the product is newer and less widely deployed outside technology companies than the gateway vendors in this list^[18].
