Sentra, an agentic data security company, has secured $150m in a strategic investment led by Capital One Ventures. The firm is betting that enterprises must lock down sensitive data before autonomous AI agents can reach it.
Capital One Ventures leads the investment, and Sentra’s existing backers have also returned: Bessemer Venture Partners, Zeev Ventures, Standard Investments, Munich Re Ventures and Key1 Capital. Under the terms of the deal, Capital One will take a seat on Sentra’s board. The capital arrives after a year in which Sentra’s growth exceeded 300% compared with the previous year.
Sentra argues that data security was designed around human users, and that three pressures have now converged. Businesses are pushing copilots, assistants and cloud AI services into production faster than governance frameworks can adapt. Sensitive records are spread across cloud, SaaS and on-premises systems, which leaves older visibility tools unable to track where the data sits or who can reach it.
Each AI agent also acts as a new identity, pulling data continuously with no central point of control. Large organisations expect their agent numbers to multiply sharply, yet few say they have governance in place to restrict agent access.
Sentra’s approach focuses on data at rest rather than inspecting each agent request in real time. Before deployment, the platform locates and classifies sensitive data, maps which people, service accounts and agents can reach it, enforces least privilege for non-human identities and deletes obsolete or high-risk data.
When an agent behaves unexpectedly, data-aware detection flags the activity and automated remediation revokes access, escalating serious issues to data owners. Afterwards, Sentra reconstructs what an agent could have accessed, giving security, legal and compliance teams evidence they can defend.
The company plans to use the funding to broaden visibility into agents, copilots and models, maintain continuous least privilege and speed up containment. It will also scale its field and channel programmes, invest in brand and marketing, and expand into new regions.
Sentra combines data discovery with identity mapping, linking every human and machine identity to the sensitive data it can access. Its analysis runs inside the customer’s own environment, so data is never copied out.
The company says this avoids the retention, residency and compliance burdens that come with rival tools that replicate customer data. It adds that the design lets it scale across clouds, SaaS, warehouses and on-premises systems at lower cost. The firm reports consistently high ratings in data security posture management on independent peer review platforms.
Sentra co-founder and CEO Yoav Regev said, “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. Traditional perimeter controls weren’t built for agents moving at machine speed. What organizations can do is make sure the data those agents reach is already secured.
“Sentra protects data where it lives and controls which identities, human and AI, can reach it, so organizations can deploy AI more quickly while staying in control. This investment lets us bring agentic data security to every enterprise putting agents to work.”
