Sentra raises $150 million to secure the data AI agents can reach

Sentra raises $150 million to secure the data AI agents can reach

Money Moves

Capital One Ventures leads the Series C and takes a board seat, betting that governing data access beats monitoring agents in real time.

Yesterday: Sentra announces $150 million Series C

Overview

Updated 1 hour ago

AI agents now read from corporate databases, file shares and cloud storage at machine speed, often with access rights copied from the humans who set them up. Sentra sells software that finds where sensitive data lives, maps which people, service accounts and agents can reach it, and removes access that is not needed. On Wednesday, Capital One Ventures led a $150 million investment in the company and took a board seat.

The round is a bet on a specific approach: secure the data before an agent touches it, rather than inspect every agent request as it happens. Sentra says it grew more than 300% year over year. Israeli press reports put its customer count at about 100 large enterprises and its revenue in the tens of millions of dollars.

Why it matters

Each AI agent is a new identity with access to corporate files. Sentra's round bets companies will pay to govern that access.

Scenarios

1

Sentra reaches $100 million in annual sales

Possible Resolves by End of 2028

Discussed by: Sentra chief executive Yoav Regev, in an interview with Israel Defense

Regev has named $100 million in sales as a target and says the company is investing in sales capacity, a London office and the US federal market. Hitting it would put Sentra in the same revenue band as established data security vendors and make a public listing or large acquisition more plausible.

2

Capital One acquires Sentra

Unlikely Resolves by End of 2027

Discussed by: No public prediction; the board seat and prior Securiti investment make it a live path

Corporate venture arms often invest before they buy. Capital One Ventures already backed Securiti, which Veeam acquired. A Sentra acquisition would give the bank direct control over how its own data access is governed as it deploys AI agents internally.

3

Sentra raises again at a $1 billion-plus valuation

Possible Resolves by End of 2027

Discussed by: Regev told Globes the next round would come 'much closer' because the market is moving faster

Sentra declined to disclose its Series C valuation. Its last disclosed valuation was about $205 million at the Series B. A new round above $1 billion would put it in the same conversation as Cyera, though still well below Cyera's $12 billion mark.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

October 2025

Veeam acquires Securiti (2025)

Veeam, a backup and data protection vendor, agreed to buy data security company Securiti for $1.725 billion. Capital One Ventures and Citi Ventures had invested in Securiti in March 2023.

Then

One of Sentra's direct competitors was absorbed into a larger platform company.

Now

The deal showed that standalone data security products could command billion-dollar exits, and that platform vendors were willing to buy them.

Why this matters now

Capital One Ventures has already invested in this category once and watched that company get acquired. Its Sentra board seat gives it a second look.

January-June 2026

Cyera's valuation run (2026)

Cyera raised $400 million in January and another $600 million in June, reaching a $12 billion valuation. Tech Funding News reported the valuation quadrupled in 18 months and that Cyera grew 3.4x year over year.

Then

Cyera became the most valuable standalone data security startup.

Now

It set the benchmark against which Sentra's growth and valuation are now measured.

Why this matters now

Sentra's $150 million round is smaller and its valuation undisclosed. The gap to Cyera is the central question for investors tracking the category.

August 2026

Zenity and the agent-monitoring alternative (2026)

Zenity raised a $125 million Series C led by Norwest to monitor and control what AI agents do inside company systems.

Then

Investors funded a second approach to the same problem: watch the agent rather than secure the data.

Now

The two approaches may converge, as larger platforms build both data governance and agent monitoring into one product.

Why this matters now

Sentra's pitch is that securing data at rest is cheaper and more reliable than inspecting every agent request. Zenity's funding is the counter-bet.
