As businesses give artificial intelligence more responsibility, Opsin is building tools to monitor what AI agents access—and whether their actions match their assigned tasks.
AI security startup Opsin has announced $21 million in funding led by SYN Ventures and Race Capital to help businesses manage the risks associated with increasingly autonomous AI agents.
Announced on 15 October 2026, the investment will support the company’s efforts to help enterprises adopt AI while maintaining oversight of sensitive data and critical systems.
More Autonomy Brings New Security Challenges
AI agents can carry out a sequence of actions to complete a task, giving them a more active role in business operations than tools that simply respond to individual prompts.
That ability creates a security challenge: companies need to understand both what an agent can access and whether its actions remain appropriate for the job it was created to perform.
Opsin’s platform is designed to detect and contain behaviour that falls outside those intended responsibilities.
“AI agents are gaining access and authority to act on critical systems, creating a security problem enterprises haven’t faced before,” said Alfred Chuang, general partner at Race Capital.
Connecting Permissions With Purpose
According to Opsin, its technology connects information about an agent’s identity, intended purpose, permissions, data access and activity. This gives security teams context for assessing potentially risky behaviour.
The company says it initially focused on preventing data oversharing as businesses adopted AI, before expanding its approach to cover the agents themselves.
Opsin connects to enterprise-approved AI platforms through application programming interfaces, or APIs. It says it can deliver an initial assessment of agent-related risks within 24 hours.
Funding to Support Product Development and Hiring
The new investment will help Opsin accelerate product development, recruit talent and support more businesses in regulated industries.
The company says its customers operate across sectors including healthcare, financial services and manufacturing, where controlling access to sensitive information is particularly important.
