AI security platform Cyera has raised $600 mn at a $12 bn valuation to expand what it calls the trust layer for enterprise AI. The round makes Cyera one of the most valuable private cybersecurity companies, with total funding above $2 bn.
The company said enterprise AI adoption has exposed a structural security gap. In 2026, 68% of organisations cannot distinguish between human activity and AI agent activity inside their own systems, according to Cyera.
Without that visibility, companies struggle to trust what AI tools access, change, or act on.
Cyera argues that the AI market has built chips, models, and compute faster than it has built governance infrastructure. Enterprises now need systems that show what AI can see, what it can do, and which risks emerge from those actions.
The latest funding round was led by Evolution Equity Partners. Cyberstarts and Temasek also participated, alongside existing investors including Accel, AT&T Ventures, Blackstone, Coatue, Spark Capital, and other backers.
Over the past year, Cyera has shipped more than 100 product capabilities across Data Security Posture Management, privacy, identity, Data Loss Prevention, and agentic security. The company says those functions now form a broader platform for enterprise AI trust.
Yotam Segev, co-founder and CEO of Cyera, said large enterprise customers want to lead AI transformation at unusual speed and scale. He said trust depends on knowing what AI can see and do inside corporate systems.
Our customers are some of the most sophisticated companies in the world. The one thing they all share is the urgency to lead AI transformation at a scale and speed the world has never seen.

Segev said Cyera has built the infrastructure layer that enterprises were missing. The funding will help the company build that layer faster for organisations deploying AI agents across business processes.
Rich Baich, CISO at AT&T, said Cyera gives the company visibility and context needed to use AI securely at scale. He said the platform helps AT&T accelerate AI adoption by controlling what AI can access and execute.
“Cyera helps provide us with visibility and context to enable secure AI at scale,” Baich said. “It helps us accelerate AI adoption by knowing and controlling what AI can see and do.”
Cyera said its growth reflects the urgency of the market. The company has tripled annual recurring revenue for three consecutive years. Over the past 18 months, its valuation has quadrupled to $12 bn.
“Over 25 years of investing in cybersecurity, it has been our experience that the companies that define infrastructure possess the depth and capabilities that solve problems competitors simply cannot,” said Richard Seewald, Founder and Managing Partner at Evolution Equity Partners. “Cyera has done that – built the layer that informs enterprises what their AI can see, learn from, and act on, at scale with precision. We are thrilled to back Cyera on this exciting journey.”
The company has grown to more than 1,500 employees across 18 countries. It has also completed five acquisitions, including Ryft and Genie, adding technology for governing AI at enterprise scale.
Richard Seewald, founder and managing partner at Evolution Equity Partners, said infrastructure-defining cybersecurity companies solve problems competitors cannot reach. He said Cyera has built a platform that shows enterprises what AI can see, learn from, and act on at scale.
Lior Simon, general partner at Cyberstarts, said enterprise AI adoption has reached a point where companies need stronger control over AI access and behaviour. He said organisations deploying AI at scale face the same barrier: they cannot trust what AI can see and do without deeper data governance.
Cyera says its AI-native platform discovers and classifies exabytes of data with more than 95% precision. The system identifies sensitive records at risk and enforces access controls without disrupting existing data pipelines or workflows.
That foundation supports Cyera’s convergence of DSPM, DLP, identity, and behaviour monitoring. The company positions this as a single platform for governing everything AI systems can access and perform inside an enterprise.
Cyera says the depth of its platform comes from more than 100 product capabilities and five completed acquisitions. The company plans to use the new capital to shorten the time required to bring its trust layer to Fortune 1000 companies.
Enterprises including Paramount, Chipotle, and Valvoline use Cyera to control which data AI systems can reach and what happens after access occurs. The platform secures data at rest, in motion, and in use, whether humans or AI agents touch it.
According to Beinsure analysts, Cyera’s $600 mn raise shows how AI security has shifted from model safety into data control and enterprise governance. The risk for companies no longer sits only in prompts or outputs. It sits in what AI agents can access, combine, retain, and act on across sensitive systems.
