Reach Security
Agentic exposure management that turns security findings into fixed risks.
About
Reach Security takes an agentic approach to exposure management: its AI agents uncover misconfigurations, control weaknesses and other exposures across SaaS and on-premises environments, then prioritize and drive guided remediation at scale. Founded in 2020 by CEO Garrett Hamilton, it raised $10M from Microsoft's M12 venture fund plus Artisanal Ventures (July 2025) and joined the Microsoft for Startups Pegasus program, with tight optimization for the Microsoft E3/E5 stack. It is well positioned for Microsoft-centric shops; teams on other stacks should check integration coverage before committing.
