Glow, an Israeli startup that has been operating in stealth mode, announced it has raised $180 million at a $1 billion valuation. The company builds AI-native endpoint security designed to address risks from unsecured AI agents.
What Glow does
As organizations increasingly deploy AI agents — autonomous software that can act on behalf of users — the security industry has struggled to keep up. Traditional endpoint protection tools weren't built for AI-driven workflows. Glow's platform is built from the ground up to monitor and secure these agents, catching malicious behavior that older systems might miss. The company says its technology is native to the AI stack, meaning it can see what agents are doing and block threats in real time.
The funding round
The $180 million round values Glow at $1 billion, making it one of the better-funded cybersecurity startups to come out of Israel this year. The company did not disclose its investors, but the size of the raise signals strong confidence in its approach. For a startup that only now revealed itself, the capital gives it a long runway to develop its product and go after customers.
Why stealth?
Glow chose to stay quiet until now, likely to avoid tipping off competitors and to refine its technology without public scrutiny. Emerging from stealth with a nine-figure valuation is a bold move. It means the company believes it has a product ready for the market and that the timing is right. The rise of generative AI and autonomous agents has created a new attack surface, and Glow is betting that enterprises will pay for dedicated protection.
The company now faces the challenge of delivering on its promise as it moves from stealth to the public eye. With $180 million in the bank, it has the resources to hire, scale, and win customers — but it also has to prove that its AI-native approach actually works against real threats.
