Cyera Ltd. has raised $400 million from Goldman Sachs, an extension of the Series G round the cybersecurity startup closed in June. That earlier deal valued the company at $12 billion, and Cyera now says it is worth more than $12 billion without providing an exact figure. The new capital will fund additional AI security features and efforts to expand adoption of its software in the federal government and international markets.
The company sells a cloud platform that helps large enterprises locate their most sensitive business records, which are often spread across dozens of systems. The software also identifies what a given record contains, who can access it and whether it is stored securely. After the first close of its Series G round in June, Cyera widened its focus to artificial intelligence agents, launching two products built to protect business records from AI-related cybersecurity risks.
The first, Agent Guardian, builds an inventory of the agents that interact with a company's data and scans them for vulnerabilities that could expose records to hacking. It can flag agents with access to more data than their work requires, and it also detects cybersecurity issues in agent tools and MCP servers. Customers can set policies defining what agents may and may not do, and Cyera automatically detects AI tools that fall outside those requirements. Agent Guardian can block a risky agent action or quarantine the agent when the problem is not confined to a single action.
Cyera released Agent Guardian alongside Cyera Endpoint, which monitors AI agents running on employee devices that traditional enterprise security tools often cannot reach. Endpoint can stop users from loading business data into non-work agents, and it prevents agents from moving records off an employee device without permission to do so.
Earlier this month, Cyera completed its $1 billion acquisition of Oasis Security Ltd., further expanding its agent security capabilities. Oasis offers a platform for securing nonhuman identities, the accounts AI agents use to log into company applications. The technology can map out the nonhuman identities in a corporate network, identify which agents use them and flag risks such as overly broad access permissions.
Cyera co-founder and Chief Executive Officer Yotam Segev said AI infrastructure is moving faster than the security architecture around it. He said the investment speeds up the company's work to bring data and identity together, so enterprises can give agents access with confidence and keep that access aligned with business intent. Segev co-founded the company with Tamar Bar-Ilan and Yonatan Itay.
