The news
Cyera, a data security company founded in 2021, announced on September 22, 2026, that it raised $400 million from Growth Equity at Goldman Sachs Alternatives. The new Cyera funding extends its Series G and keeps its valuation above $12 billion as it targets AI agent risks.
The original Series G was led by Evolution Equity Partners. SecurityWeek reported on June 10, 2026, that the first tranche was $600 million at a $12 billion valuation, so the new money does not set a higher price. Israeli business site Calcalist said the extension brings Cyera's 2026 fundraising to $1.4 billion, after a $400 million round in January 2026.
Cyera sells software that finds and classifies sensitive corporate data and controls who, or what, can reach it. Its current pitch centers on AI agents: the company says enterprises need to know what data agents can access and what they do with it. Products named in the announcement include Agent Guardian, Cyera Endpoint, data security posture management (tools that map where sensitive data lives), data loss prevention, privacy and identity modules.
The company said the capital will fund new AI security capabilities, a deeper push into the U.S. federal market and further growth across Europe, the Middle East, Africa and Asia-Pacific. Chief executive Yotam Segev said large enterprises want to trust “what AI agents can see and do” before scaling them.
Cyera has also been buying. Its announcement cites the acquisition of Oasis Security, which added management of non-human identities such as service accounts and agent credentials. SecurityWeek reported that the Oasis deal, in July 2026, was valued at $1 billion. Named customers include Paramount, Chipotle and Valvoline, and SecurityWeek said Cyera serves 20% of the Fortune 500 and employs more than 1,500 people.
Existing investors listed by the company include Accel, Blackstone, Cyberstarts, Georgian, Lightspeed and Sequoia. Cyera did not disclose revenue, and Calcalist reported that the Goldman Sachs Alternatives extension came without a new valuation, leaving the price where the June round set it.

Why CEOs should care
For CISOs, the message from Cyera and its investors is that data security and identity management are merging as agents multiply. If your company tracks human access in one tool and data sensitivity in another, ask whether either can answer a basic question: which AI agents can read regulated data right now, and who approved that access. Vendors in this space, including Cyera, should be able to demonstrate that inventory on your own environment during a proof of concept.
For CFOs and procurement leads, a flat-valuation extension is worth reading carefully. It suggests strong investor appetite but not necessarily a new growth milestone, and Cyera has not disclosed revenue. Buyers negotiating multiyear contracts with any fast-acquiring security vendor should seek price protections, clarity on which acquired products will be merged or retired, and service commitments that survive product consolidation.
Boards and audit committees can ask vendors whether a federal push like Cyera's will bring new compliance certifications or security reviews, and whether those extend to the products commercial customers use. Ask your security team whether vendor due diligence now covers how each tool handles agent identities, not just employee logins. Directors should also ask how quickly the company could revoke every credential held by a single misbehaving agent, and who would make that call outside business hours.
The bigger picture
Two days after Cyera's announcement, on September 24, 2026, enterprise browser company Island announced a $400 million Series F at a $6.4 billion valuation. Island's round was led by Evolution Equity Partners, which also led Cyera's June Series G, and its pitch has a similar focus on controlling what agents can do. Calcalist's tally shows Cyera's valuation climbing from $3 billion in 2024 to $12 billion by June 2026, a pace that puts pressure on established data protection vendors to show comparable agent-focused features.
What’s next
The next signals to watch are product and procurement ones: whether Cyera wins federal authorizations tied to its new push, how it folds Oasis Security into a single platform, and whether it discloses revenue or customer counts that support a higher valuation in its next round. Customers should expect continued acquisitions, given the company's stated plan to build a unified platform.
What “Fact-checked” means
Fact-checking means testing a story’s facts against the evidence before it is published. This story went through at least two separate checks before this version was published.
- What we checked
- Its names, figures, dates, job titles, quotes and who said what were checked against the story’s sources, including its main source where it could be opened. The headline was checked for accuracy and overstatement.
- How
- A first check reviewed the whole story. If it passed, a second, skeptical check went back to the sources to look for mistakes in the most important facts. If a check flagged the story, it was edited to fix the problems found, and a separate re-check then reviewed the whole story again.
- Who
- The checks are made with our newsroom’s technology tools, as steps kept separate from the writing, under rules set by our editor, Hussein Mukhtar. A story the checks still flag is not published automatically; it is held for the editor, who decides whether it is fixed, published or dropped.
- If something is wrong
- “Fact-checked” does not mean error-free. If a material error is found after publication, we correct the story and add a note saying what changed. Report an error
