Do you trust that your employer can effectively secure the AI tools used in your workplace?

Startup Opsin has secured $21 million in a new funding round led by SYN Ventures and Race Capital. The company aims to use the capital to expand its workforce as it addresses growing corporate concerns over the security of AI agents.

Why it matters

Companies are increasingly concerned about AI agents accessing confidential information after incidents, such as one where an agent granted employees unauthorized access to financial data. Opsin monitors these corporate environments to identify active AI agents, their tools, and the data they access to flag risky behavior.

Opsin closed a $21 million funding round to support its current team of approximately 20 employees. The company is now focused on scaling its sales and engineering departments.
