Sentra, a data security company based in New York and Tel Aviv, has raised $150m in a strategic investment led by Capital One Ventures. The company announced the round on 4 November 2026, and a Capital One representative will join its board.
Existing investors Bessemer Venture Partners, Zeev Ventures, Standard Investments, Munich Re Ventures and Key1 Capital are named in the announcement as backers. The release did not give the round a series name or disclose a valuation.
Chief executive Yoav Regev told Calcalist that the valuation has tripled since the previous round. Calcalist reported estimates that it is now close to $1bn but has not reached that mark, and that Sentra has raised more than $250m in total. A small part of the new money goes to employees through a secondary sale, according to Calcalist, with most of it going to the company.

What Sentra does
Sentra's software finds sensitive data across a company's systems and controls which people and which AI identities can reach it. The platform combines several categories of data security tools: posture management, detection and response, access governance and data loss prevention.
The company's pitch is that AI agents and copilots now move through corporate data at a pace older security controls were not designed for. "Traditional perimeter controls weren't built for agents moving at machine speed," Regev said in the release.
Lyft is a named customer. Its chief information security officer, Chaim Sanders, said in the release that his teams need to know what data their agents can reach before switching them on. Sentra said it grew more than 300% year on year over the past year. Calcalist reported that it has about 100 large enterprise customers in the US and Europe and revenue in the tens of millions of dollars.
What the money is for
Sentra said it will add features aimed at AI agents, including visibility into agents and models, least-privilege access for non-human identities and faster containment of incidents. It also plans to expand sales and channel programmes, marketing and its presence in new countries.
Regev told Calcalist that the company plans to double its workforce in Israel and the US, open a London office and enter the US federal market, with government sales expected to begin in the second half of 2027. He also said Sentra could buy a company to speed up its work on data loss prevention and agent security. Calcalist reported that Sentra has 130 employees, 65 of them in Tel Aviv.
The funding so far
Sentra was founded in 2021 by Regev, a former commander of Unit 8200's cyber centre; president Asaf Kochan, also a former Unit 8200 commander; chief technology officer Ron Reiter, who previously headed Oracle's Tel Aviv development centre; and Yair Cohen, who worked at Microsoft and Datadog.
In April 2025 the company raised a $50m Series B led by Key1 Capital, according to SiliconANGLE, which reported at the time that it had raised more than $100m in total. SiliconANGLE also reported an earlier $30m round in January 2023.
