Sentra raises $150m led by Capital One Ventures for AI data security

4 November 2026: Sentra, a data security company based in New York and Tel Aviv, says Capital One Ventures has led a $150 million strategic investment in it, joined by existing investors Bessemer Venture Partners, Zeev Ventures, Standard Investments, Munich Re Ventures and Key1 Capital. A Capital One representative will join Sentra's board, and the company says its business grew more than 300% over the past year.

Not yet independently verified. Sentra's release calls the round a strategic investment; only its CTO's blog post calls it a Series C. No valuation is given, and the growth figure is the company's own. We will update this when it can be confirmed, and remove this note.

Four security categories in one product

Sentra sells a single platform that covers what are usually four separate purchases: data security posture management (DSPM), which finds and classifies sensitive data across cloud and on-premises stores; data detection and response; data access governance; and data loss prevention. The company stresses that it analyses data in place, inside the customer's own environment, rather than copying it out to its own cloud.

Sentra was founded in 2021 by Yoav Regev, its chief executive, Asaf Kochan, Ron Reiter, its chief technology officer, and Yair Cohen. Its release quotes Lyft's chief information security officer, Chaim Sanders, as a customer.

Agents as the new heavy users of data

The round is framed around AI. "AI agents are now the busiest consumers of enterprise data," Regev says in the release. The product work the money pays for is aimed at that: showing which agents, copilots and models touch which data, enforcing least privilege continuously for both human and non-human identities, and containing an agent that reaches data it should not.

The rest goes to growth: field and channel programmes, brand, and new geographies. Reiter's blog post adds that Sentra will scale engineering and product teams globally and deepen its presence in North America and Europe.

A bank's venture arm on the board

The lead investor is worth noting. Capital One was one of the early large banks to move its core systems to the public cloud, and a seat for its venture arm on the board of a data security vendor signals the kind of customer Sentra is selling to: regulated firms with very large data estates and a growing number of internal AI tools reading from them.

For buyers comparing DSPM tools, the practical questions are whether scanning really stays inside their own accounts, which data stores and SaaS applications are covered today, and how agent and service identities are discovered and mapped to the data they can reach. The release does not give a valuation, and only Reiter's blog post calls the round a Series C.
