Straiker raises $64M for agentic security
Straiker raised a $64M Series A to build security tools for agentic AI workflows, bringing total funding to $85M.
As companies deploy more AI agents, security has to adapt to software that can act, connect and make decisions.
What happened
Straiker raised a $64M Series A, bringing total funding to $85M.
The round was backed by investors including Marathon Management Partners, Citi Ventures, Illuminate Financial, Workday Ventures, Bain Capital Ventures and Lightspeed.
Why it matters
Traditional security tools were built around human users, applications and known software workflows. AI agents add a new layer: systems that can take actions, use tools and interact with company data.
That creates new risks around permissions, behaviour, monitoring and control.
The bigger picture
Agentic AI is creating a new security category. Companies need ways to understand what agents can access, what they are doing and how to stop unwanted behaviour before it becomes a bigger problem.
Straiker’s large Series A shows investors expect security to become one of the core infrastructure layers of the AI-agent market.
