Sentra, a data security company with offices in New York and Tel Aviv, has raised $150 million in a funding round led by Capital One Ventures. The round is one of the largest this year for a company focused on protecting enterprise data in the age of AI.
The round was announced on Wednesday, November 4, and has been described as a Series C. Capital One Ventures, the venture investment arm of the US bank, will take a seat on Sentra's board. Existing and new investors including Bessemer Venture Partners, Zeev Ventures, Standard Investments, Munich Re Ventures and Key1 Capital also took part.
Sentra has now raised more than $250 million in total. The company says it has grown by more than 300% year on year.
Securing data for the AI era
Sentra's platform helps organisations find, classify and protect sensitive data across their cloud environments, software applications and on-premises systems. The category is often known as data security posture management (DSPM).
As companies store growing volumes of data across many systems, it has become harder for security teams to know where sensitive information is located, who can access it and whether it is properly protected. Sentra's platform scans an organisation's data to identify sensitive information, such as customer records, financial data and intellectual property, and flags risks.
The rise of AI has made that challenge more urgent. Companies are deploying AI tools and agents that access large amounts of internal data to answer questions, automate tasks and make decisions. If those agents can reach sensitive data without appropriate controls, the risk of leaks and misuse increases.
AI agents as data consumers
Co-founder and chief executive Yoav Regev has framed the company's mission around this shift. "AI agents are now the busiest consumers of enterprise data," he said.
AI agents are software systems that can carry out tasks on behalf of users, often by accessing multiple applications and data sources. Unlike human employees, they can process vast amounts of information very quickly, and they may not always respect the data access boundaries that organisations intend.
Sentra's platform is designed to give organisations visibility into what data their AI systems can access and to enforce policies that keep sensitive information protected.
Why a bank is leading the round
Capital One's decision to lead the round is significant. Banks handle enormous amounts of sensitive customer data and face strict regulatory requirements for protecting it. They are also among the largest adopters of AI in the corporate world.
Capital One has a reputation as one of the most technology-focused US banks, having moved much of its operations to the cloud. Its venture arm invests in companies whose technology is relevant to the bank's own needs, as well as to the wider financial services industry.
A strategic investor of this kind can bring more than capital. It can provide insight into the needs of large, highly regulated organisations and may help Sentra build relationships with other financial institutions.
Munich Re Ventures' participation also stands out. As the venture arm of one of the world's largest reinsurers, it brings an insurance industry perspective on cyber risk, an area in which insurers have significant exposure.
Customers and competition
Sentra's customers include companies such as Lyft, which uses the platform to manage data security across its systems. The company serves organisations across industries including financial services, healthcare and technology.
The data security market is competitive. One of Sentra's main rivals is Cyera, another Israeli-founded data security company that has also raised large sums from investors. Major cybersecurity vendors and cloud providers also offer data security tools.
Sentra's rapid growth suggests demand for these tools is strong. As AI adoption accelerates, organisations are increasingly concerned about data exposure, and many are looking for specialised solutions.
Israel's cybersecurity ecosystem
Sentra is part of Israel's large and successful cybersecurity industry. The country has produced many leading security companies, built on a deep pool of technical talent, much of it with experience in military intelligence units.
Israeli cybersecurity startups have continued to attract significant funding in 2026, despite regional geopolitical tensions. Investors see the sector as particularly well placed to benefit from AI-driven changes in security needs.
Several Israeli security companies have been acquired by large technology firms in recent years, often at high valuations. That has reinforced investor confidence in the sector's potential.
Why data security matters for India
Data security is an increasingly important issue for Indian businesses and regulators. India's Digital Personal Data Protection Act sets out rules on how organisations must collect, store and protect personal data. Companies that fail to comply can face significant penalties.
Indian enterprises are also adopting AI rapidly, from banks and insurers to IT services companies and retailers. As they do so, they face the same challenges that Sentra addresses: knowing where sensitive data is, who can access it and how AI systems use it.
India's large IT services industry is another point of connection. Indian companies manage data and technology systems for clients around the world, and data security tools are an important part of the services they provide.
For the Indian diaspora working in cybersecurity, AI and enterprise software in the US and Israel, Sentra's growth highlights the opportunities in a sector that is becoming central to AI adoption.
What the funding will support
Sentra is expected to use the new capital to expand its platform, grow its sales and customer support teams, and invest in research and development. Strengthening its capabilities around AI agents and data access will be a priority.
The company may also expand its presence in new markets and industries. With financial services investors such as Capital One and Munich Re on board, financial institutions are likely to be a key area of focus.
The broader trend
Sentra's funding round reflects a broader trend in cybersecurity. As AI transforms how businesses operate, it is also changing the threats they face and the tools they need to protect themselves.
Investors are backing companies that address AI-specific security challenges, including protecting data from misuse by AI systems, securing AI models themselves, and defending against attacks that use AI. Security spending is expected to keep growing as organisations deploy more AI.
Outlook
With more than $250 million raised, growth of more than 300% and backing from strategic investors, Sentra is well positioned to compete in one of the most important areas of enterprise security.
The key challenges will be keeping pace with rapid change in AI, competing with well-funded rivals, and showing that its platform can protect data across increasingly complex environments. As AI agents become more common in the workplace, the demand for the kind of protection Sentra offers is likely to keep rising.
