Cyera, a data security company building what it describes as a trust layer for enterprise AI, has secured a $400m extension to its Series G round from Growth Equity at Goldman Sachs Alternatives to help organisations control what AI agents can access and do.
The Series G itself was led by Evolution Equity, with the Goldman Sachs capital now added on top. Cyera plans to use the money to build out a single platform that manages access rights for every person, machine and AI agent operating inside an organisation.
The funding will be channelled into fresh features on Cyera’s AI Security product roadmap. The company also intends to push further into the federal market and keep growing internationally across EMEA and APAC, regions where it says businesses are rapidly increasing their demand for oversight of AI agents.
The raise comes as AI agents take on a growing share of enterprise work. Unlike conventional software, these agents can reason, operate under identities, call tools, reach sensitive data and act independently at very high speed. The broader their access, the more useful they are, but the damage also grows if that access is breached or drifts away from what the business intended. Cyera argues that existing security frameworks were designed around people and applications rather than vast numbers of autonomous actors, and that protecting this new environment means combining data and identity controls.
Cyera has focused on protecting the data layer since it was founded, and this year it broadened that remit to cover the agents interacting with that data. Its Agent Guardian and Cyera Endpoint products offer oversight of AI agents, monitoring not only prompts and outputs but also the tool calls, database queries and actions taking place in between. This coverage stretches from the cloud down to endpoint devices, where locally run agents such as Claude Code and Cursor are handling a rising volume of sensitive tasks.
Its purchase of Oasis Security merges this visibility with non-human identity (NHI) management within one system. By linking the location of sensitive data with the humans, machines or agents able to reach it, the combined offering provides a single method of governing access.
Cyera carries a valuation of more than $12bn and counts Accel, Blackstone, Cyberstarts, Georgian, Lightspeed and Sequoia among its backers.
Cyera cofounder and CEO Yotam Segev said, “Global 2000 enterprises are telling us the same thing: they need to trust what AI agents can see and do before they can scale them.
“AI infrastructure is moving faster than the security architecture around it. This investment accelerates our work to bring data and identity together, so enterprises can give agents access with confidence and keep that access aligned with business intent.”
Goldman Sachs Alternatives managing director within Growth Equity Irit Kahan said, “Securing AI will be one of the defining categories in enterprise technology over the next decade.
“Cyera was the first to bring data and identity together, and as agents multiply faster than anyone can track, the gap between what they’re trusted to do and what they can actually reach is becoming increasingly dangerous. Cyera’s technology, customer traction, and execution position it to become the platform enterprises rely on to secure AI.”
