Cyera Adds $400M Series G Extension From Goldman Sachs

Nineteen days after completing its $1B acquisition of Oasis Security, Cyera added a $400M investment from Growth Equity at Goldman Sachs Alternatives to its Series G. The September 22, 2026 extension follows the $600M Series G that Evolution Equity Partners led in June, bringing the disclosed round total to $1B.

Cyera says the company is now valued above $12B and has raised more than $2.7B. The capital will support new AI Security capabilities, deeper expansion in the U.S. federal market, and international growth across EMEA and APAC.

The transaction matters because Cyera is trying to combine two security systems that enterprises have historically managed apart. Data security explains what information exists and why it matters. Identity security explains which people, machines, applications, and AI agents can reach it. Agentic software turns the gap between those systems into a real-time operating risk.

What Cyera Added to Its Series G

The official September announcement describes the $400M as an extension from Growth Equity at Goldman Sachs Alternatives to the Series G led by Evolution Equity Partners. It does not disclose the investment instrument, ownership percentage, dilution, board changes, or a new valuation step-up.

Cyera’s June financing raised $600M at a $12B valuation. Evolution Equity Partners led that round, with Cyberstarts and Temasek participating alongside existing investors including Accel, AT&T Ventures, Blackstone, Coatue, and Spark Capital. The Goldman Sachs extension brings the same Series G to $1B.

The company’s capital history has moved almost as quickly as its product scope. A $400M Series F led by Blackstone valued Cyera at $9B in January 2026. A $540M Series E led by Georgian, Greenoaks, and Lightspeed Venture Partners valued it at $6B in June 2025. The company had reached a $3B valuation with a $300M Series D in November 2024, seven months after a $300M Series C valued it at $1.4B.

Why Data and Identity Are Converging

Cyera was founded in 2021 by Yotam Segev, Tamar Bar-Ilan, and Yonatan Itai. Its original problem was data visibility: helping enterprises discover sensitive information, classify it, understand who could access it, and remediate exposure across cloud and software environments. That foundation expanded into Data Security Posture Management, Data Loss Prevention, privacy, access governance, and AI security.

AI agents increase the pressure because they operate through identities while moving across tools and data at machine speed. A credential can be legitimate while the action it authorizes is stale, excessive, or disconnected from current business intent. Traditional reviews were designed around employees and applications that moved slowly enough for a manager, security team, or incident process to intervene.

Agent Guardian is Cyera’s answer to that change. The product creates an inventory of sanctioned and unsanctioned agents, maps the models, tools, identities, and data connections behind them, monitors tool calls, and can block unsafe actions before execution. Cyera Endpoint extends visibility to local agents operating on employee devices.

The Oasis Acquisition Changes the Platform

The completed acquisition of Oasis Security adds non-human identity management to Cyera’s data intelligence. Oasis built controls for machine and agent identities, including inventory, ownership, access, and policy enforcement. Its platform is becoming Cyera Identity.

That combination gives Cyera a clearer architectural thesis. Data context identifies the sensitive asset and the consequences of exposure. Identity context identifies the human, workload, machine, or agent requesting access. A unified platform can evaluate both sides before an action occurs instead of asking separate teams to reconstruct the decision afterward.

Irit Kahan, Managing Director within Growth Equity at Goldman Sachs Alternatives, described the emerging risk as the widening gap between what agents are trusted to do and what they can actually reach. Goldman’s investment is a wager that closing that gap will become a defining enterprise-security category.

Where the New Capital Goes

Cyera says the extension will fund additional AI Security product capabilities, expansion in the federal market, and continued growth across EMEA and APAC. The federal opportunity is real but unfinished. Cyera for Government was listed as FedRAMP In Process under the Rev5 Agency path as of August 24, 2026, with no authorization letters yet recorded.

International expansion also follows a larger operating footprint. In January 2026, Cyera reported more than 1,100 employees, operations in 15 countries, 3.4x revenue growth, and customers representing 20% of the Fortune 500. The company also reported partnerships with Microsoft Purview, AWS, and Cohesity. Those figures are company-reported and should be read as traction claims rather than audited performance.

What the Funding Signals

Cyera is financing integration as much as expansion. The company has added products across data discovery, DLP, privacy, identity, endpoint security, and agent runtime controls while acquiring Trail Security, Ryft, Genie Security, and Oasis Security. The market opportunity is broad, but the product has to feel like one control plane to a CISO, not a portfolio assembled at fundraising speed.

The $400M extension gives Cyera more time and resources to solve that integration problem. It also raises the standard of proof. Federal certification, international deployments, product adoption, and customer evidence will matter more than another valuation headline.

AI agents will not wait for quarterly access reviews. Every tool call, database query, and automated action creates a fresh question about who or what should be trusted with which data. Cyera’s $1B Series G is financing an attempt to answer that question continuously, before a valid identity turns an outdated permission into an operating incident.
