Sentra Funding Reaches $150 Million Series C Led by Capital One Ventures

Sentra, the New York- and Tel Aviv-based data security firm, closed a $150 million Series C round on November 4, 2026. Capital One Ventures led the round and took a board seat, bringing total funding above $250 million.

Sentra Funding Details and Investor Participation

The round included participation from existing investors Bessemer Venture Partners, Zeev Ventures, Standard Investments, Munich Re Ventures, and Key1 Capital. A small secondary portion allowed employee liquidity. Valuation reportedly tripled from the prior round, positioning the company near unicorn status though exact figures remain private. The Series B of $50 million closed in April 2025 under Key1 Capital leadership.

Sentra reported more than 300 percent year-over-year revenue growth and serves roughly 100 large enterprise customers in the United States and Europe. Revenue sits in the tens of millions. The company employs about 130 people, with 65 based in Tel Aviv. Funds will support product expansion for agent and copilot visibility, continuous least-privilege enforcement for both human and non-human identities, and data-at-rest protection with rapid containment features.

Plans include scaling field and channel programs, opening a London office, and entering the U.S. federal market around late 2027. Growth targets point toward $100 million in annual recurring revenue, with potential team expansion that could double headcount over the next two years.

Platform Capabilities for AI Data Governance

Sentra’s platform discovers and classifies sensitive data across IaaS, PaaS, SaaS, data warehouses, on-premises, and hybrid setups without moving customer data. It maps access rights held by both human users and AI agents, including inherited permissions, then enforces least-privilege policies at machine speed. The system also supplies remediation workflows and visibility into what agents, copilots, and models can reach inside corporate environments.

Traditional perimeter defenses fall short when AI agents become the busiest consumers of enterprise data, according to CEO Yoav Regev. The platform addresses this gap by securing data where it resides rather than relying solely on network controls. Lyft CISO Chaim Sanders noted that organizations need clear insight into agent data reach before deploying new AI workloads.

Founders Yoav Regev, Asaf Kochan, Ron Reiter, and Yair Cohen established the company in 2021 after experience in Unit 8200. The initial focus on cloud data security posture management has evolved into a unified agentic data security offering that supports compliance requirements while scaling inside customer environments.

Enterprise Implications and Next Steps

Enterprises adopting AI agents face ungoverned data access risks that can slow deployment or create compliance exposure. Sentra’s approach supplies mapping and control layers that allow security teams to maintain oversight without blocking AI initiatives. Practical use cases include identifying over-privileged service accounts tied to copilots and triggering automated containment when anomalies appear.

Competitors in the broader cloud data security space have focused mainly on discovery and classification. Sentra differentiates through explicit support for non-human identities and inherited permission chains that AI agents often exploit. Organizations evaluating similar tools should assess coverage across their full stack of SaaS and data warehouse environments plus integration with existing identity providers.

The company will next prioritize deeper agent visibility features and geographic expansion. No timeline has been set for a subsequent funding round or IPO. Security leaders can review Sentra’s public documentation on mapping AI data access to determine fit with current governance programs.
