Cyera, a data security company building a unified data and identity platform for enterprises, has secured a $400m investment from Goldman Sachs to strengthen control over what AI agents can access and do.

The capital comes from Growth Equity at Goldman Sachs Alternatives as an extension to Cyera’s Series G, which was led by Evolution Equity. The funding supports the company’s goal of creating one platform to govern access for every human, machine and AI agent operating within an organisation.

Cyera plans to put the money towards new features on its AI Security product roadmap. It will also use the funding to expand further into the federal market and to keep growing internationally across EMEA and APAC, regions where enterprises increasingly want oversight of their agents.

The raise comes as AI agents take on a growing share of enterprise work. These agents differ from conventional software because they reason, adopt identities, call on tools, reach sensitive data and act on their own at machine 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 intends.

According to Cyera, this makes agents one of the quickest-growing security threats enterprises have faced. Existing security architecture was designed around people and applications rather than millions of autonomous actors, and the company argues that protecting the agentic enterprise requires a model that unites data and identity.

Cyera began by protecting the data layer and this year extended that protection to the agents working with it.
