Sentra, a data security company with offices in New York and Tel Aviv, said on 4 November 2026 that it has taken in $150 million led by Capital One Ventures, which also gets a seat on its board. Bessemer Venture Partners, Zeev Ventures, Standard Investments, Munich Re Ventures and Key1 Capital, all existing backers, joined in. The company calls it a strategic capital investment, though BankInfoSecurity labels it a Series C.
“AI agents are now the busiest consumers of enterprise data, and many of them inherit access to data that hasn’t been fully classified or governed.”

The money brings Sentra's total funding to roughly $250 million, put at $253 million across four rounds. The company cites growth of more than 300 percent year over year without saying what that measures, and it has not disclosed a valuation. Headcount has climbed to 210, from about 85 when Dealroom counted in April 2025. Its platform combines data security posture management, detection and response, access governance and loss prevention, and it reads data inside the customer's own environment instead of copying it out.
Co-founder and CEO Yoav Regev frames the pitch around AI agents, which now touch more enterprise data than anything else and often inherit access to information nobody has fully classified. His answer is to secure the data before agents reach it. He says Sentra can beat Proofpoint and Cyera on technology, on keeping data in the customer's environment, on cost and on classification accuracy. Unite.AI points out that those scale and cost claims come from the company and have not been compared independently, and Tech Funding News notes that Sentra monitors agents less than some rivals do.

The raise lands in a busy field. Capital One Ventures and Citi Ventures backed Securiti in 2023, and Veeam agreed in October 2025 to buy it for $1.725 billion. Cyera's valuation rose to $12 billion after a $600 million round in June 2026, and Zenity raised a $125 million Series C in August. Wiz, owned by Google Cloud, has used Sentra's data classifications since April 2026.
About Sentra
Sentra is a data security company based in New York and Tel Aviv, founded in 2021 by Yoav Regev, Asaf Kochan, Ron Reiter and Yair Cohen. Its platform scans data inside the customer's own infrastructure across multi-cloud, on-premises and AI environments, using an AI classification engine the company says is more than 95 percent accurate.
The founders are veterans of Israeli military intelligence: Kochan headed Unit 8200 until early 2021, and Regev led its cyber department. Standard Investments led a $30 million Series A in January 2023, and Key1 Capital led a $50 million Series B in April 2025.
Sentra plans to spend on visibility into agents, copilots and models, on least-privilege access for both human and AI identities, and on faster containment when an agent behaves oddly. It also wants more field and channel sales, new markets, and time-limited, on-demand permissions for agents. Regev expects the buyers to widen beyond security chiefs to CIOs and chief data officers. The founders, who come from Israeli military intelligence, spoke to about 200 companies before starting out in 2021. Ron Reiter sold Crosswise to Oracle for $50 million in 2016, and Yair Cohen was a senior product manager at Datadog.
