Sentra raises $150 million to secure data for AI agents

Securing the AI workforce

Sentra, a data security company based in New York and Tel Aviv, has secured $150 million in new capital. This investment was led by Capital One Ventures and includes participation from several other firms, including Bessemer Venture Partners and Munich Re Ventures. The funding is intended to accelerate the company's development of an agentic data security platform.

The company is responding to a massive surge in enterprise demand for security tools that can handle artificial intelligence. As organizations adopt AI more broadly, they face new risks regarding how sensitive information is handled by automated systems. Sentra reported more than 300% year-over-year growth, highlighting the urgency of this problem for large businesses.

A representative from Capital One will join Sentra's board of directors as part of this deal. The company plans to use the capital to expand its global operations and grow its customer base. They are specifically targeting the security challenges created by AI agents, which act as independent digital identities capable of executing tasks at machine speed.

Beyond the network perimeter

Traditional security tools often focus on network boundaries or monitoring what individual human users do. Sentra takes a different approach by focusing on the data itself. Their platform identifies, classifies, and governs sensitive information across various environments, including cloud systems, software-as-a-service applications, and on-premises infrastructure.

The platform integrates four distinct security capabilities into a single unified approach. These include data security posture management (DSPM), data detection and response (DDR), data access governance (DAG), and data loss prevention (DLP). By combining these, the system provides a comprehensive view of where sensitive data lives and who has the keys to it.

One of the core strengths of the technology is its ability to map access for both humans and non-humans. This includes employees, service accounts, and AI agents. The system helps organizations enforce least-privilege access policies, which ensure that any identity only has the minimum level of access required to do its job.

Privacy-first architecture

A critical feature of Sentra's technology is how it processes information. The platform analyzes data within the customer's existing environment rather than moving that data to external infrastructure. This design choice is specifically intended to reduce risks related to data residency, retention, and compliance for highly regulated industries.

By keeping the data in place, businesses can maintain tighter control over their information. The system continuously identifies sensitive details and evaluates the permissions associated with them. It can also detect unusual interactions with that data and automatically revoke access or remove risky sharing configurations when it spots a problem.

This architecture allows companies to stay compliant while still utilizing advanced security features. It addresses the need for visibility without the security risks of data migration. The goal is to provide a clear picture of the data landscape while keeping the information behind the company's own digital walls.

Real-world AI deployment

The company is already working with major organizations to solve these problems. For example, Lyft uses Sentra to evaluate data access and support the secure rollout of its own AI technologies. Chaim Sanders, the Chief Information Security Officer at Lyft, noted that the tool helps the company move fast with AI by providing answers on what data agents can reach.

The platform helps security teams act as enablers rather than roadblocks. Instead of slowing down the adoption of new tools, Sentra provides the visibility needed to turn them on safely. It identifies inherited permissions that might otherwise be overlooked, which is a common issue when deploying complex AI systems across a large enterprise.

Sentra's CEO, Yoav Regev, stated, "Sentra protects data where it lives." This focus on identity-based data control allows organizations to deploy agents more quickly while maintaining oversight of their most sensitive assets.

The road ahead

With the new funding, Sentra intends to deepen its visibility into AI agents, copilots, and various models. They plan to advance their capabilities in continuous access governance and automated threat containment. The company will also focus on expanding its marketing efforts and building out its sales and channel partnerships.

The investment positions Sentra to take a larger role in the enterprise AI security market. As more companies move toward autonomous agents, the need for tools that can govern information at machine speed will likely increase. Sentra is positioning itself as a primary solution for this specific technical hurdle.

Looking forward, the company will continue to invest in international expansion to reach a global audience. They aim to help every enterprise that puts agents to work by providing a secure foundation for those agents to operate. The focus remains on making sure the data those agents reach is already secured and governed.
