Sentra Raises $150 Million to Secure Enterprise AI Agent Data

Funding targets data security for AI agents

Sentra said the investment brings Capital One Ventures alongside existing investors Bessemer Venture Partners, Zeev Ventures, Standard Investments, Munich Re Ventures and Key1 Capital. The company said the funding follows more than 300% year-over-year growth as enterprises use its platform to understand their data, control access by human and AI identities, and maintain governance for AI and autonomous agents.

Sentra, which was founded in 2021 and is headquartered in New York and Tel Aviv, describes itself as an agentic data security company. Its platform combines data security posture management, data detection and response, data access governance and data loss prevention.

Protecting data before agents reach it

Sentra’s approach focuses on data at rest, meaning data remains in the cloud, SaaS applications, data warehouses, on-premises file shares and other knowledge stores where it already lives. Rather than inspecting every agent request as it happens, the company says it governs the data and access rights that agents depend on in advance.

Before an agent accesses data, Sentra finds and classifies sensitive information across environments and maps what people, service accounts and AI agents can reach, including inherited access. It also enforces least privilege for non-human identities and removes redundant, obsolete and high-risk data that agents should not find.

During unusual activity, data-aware detection can flag access to sensitive data. Sentra says automated remediation can revoke access and remove risky sharing, while routing high-risk issues to data owners and existing workflows. Afterward, the platform shows what an agent could have reached and provides business context for the affected datasets.

“AI agents are now the busiest consumers of enterprise data,” Sentra co-founder and CEO Yoav Regev said. He added that organizations should ensure the data agents reach is already secured, allowing them to deploy AI while retaining control.

Expansion plans and the enterprise case

Sentra said the investment will support broader visibility into agents, copilots and models, continuous least privilege for human and non-human identities, protection for data at rest, and faster containment when an agent behaves unexpectedly. The company also plans to expand its field and channel programs, grow its brand and marketing, and enter new geographies.

The platform analyzes data inside the customer’s environment, according to Sentra, so sensitive data does not leave it. The company says this approach avoids creating a separate data estate that would bring additional retention, residency and compliance risks, while supporting coverage across clouds, SaaS, data warehouses and on-premises systems.

The announcement reflects Sentra’s view that enterprise security must account for both the data itself and the identities accessing it as AI agents operate at machine speed. Lyft CISO Chaim Sanders said the company uses Sentra to determine what data its agents can reach across its environment before enabling them, helping security support AI deployment.
