Cyera, the AI-native data security specialist, has secured a $400m extension to its Series G from Growth Equity at Goldman Sachs Alternatives, strengthening its drive to build a single platform that controls access for every person, machine and AI agent inside the enterprise.
Evolution Equity led the original Series G round. Cyera will use the additional capital to deliver further capabilities on its AI Security roadmap, while also funding a stronger presence in the federal market and continued expansion across EMEA and APAC, regions where businesses are rapidly stepping up demand for tools that supervise agents.
The investment comes as companies increasingly deploy AI agents as a new layer of their workforce, drawn by the prospect of faster output, higher productivity and greater innovation. Unlike older software, these agents can think through problems, adopt identities, trigger tools, open sensitive data and carry out tasks on their own at machine speed.
Wider permissions make them more valuable, but they also magnify the fallout if that access is breached or pulls away from what the business intends. Cyera argues this pairing has made agents one of the fastest-growing security threats enterprises have faced. Traditional enterprise defences were designed to protect people and applications, not millions of independent actors, and the company believes the answer lies in a model that unites data and identity.
Protecting the data layer has been central to Cyera from the outset, and during this year the company stretched that protection to the agents that operate on the data. Its Agent Guardian and Cyera Endpoint tools let organisations see and hold AI agents to account, logging prompts and responses alongside the tool calls, database queries and actions taken between them. Coverage runs from cloud environments to endpoint devices, where local agents including Claude Code and Cursor now carry out a rising volume of sensitive work.
Cyera’s acquisition of Oasis Security merges this agent oversight with non-human identity (NHI) management in one system. Mapping where sensitive data sits against the people, machines or agents capable of reaching it, the joint platform hands enterprises a unified way to manage access across all three.
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.”
