Israeli Cybersecurity Startup Glow Reaches $1.2 Billion Valuation Within One Year

Israeli cybersecurity startup Glow announced the completion of a $180 million funding round, valuing the company at $1.2 billion and making it a unicorn less than a year after its founding. Since its establishment last year, Glow has completed three funding rounds: a $20 million seed round, a $60 million Series A, and now a $100 million Series B. The latest round was led by Sequoia Capital, Cyberstars, Greenoaks, and Redpoint Ventures, with participation from Index Ventures, Omri Casspi's Swish, Lux Capital, and Holly Ventures. The funds will be used to expand sales and marketing, hire new employees, and continue investment in research and development.

Glow was founded by Roy Tigger, former VP of Engineering at Meta and co-founder of Onavo, alongside Omer Zinger, ex-Head of Cyber Strategy at Snowflake, and Ofir Aryeh, former R&D VP at Claroty and a 8200 unit alumnus. The company’s leadership recently expanded to include Arnon Yosef, a former senior product executive at Meta, and Emily Heath, former Chief Information Security Officer at United Airlines and DocuSign. Glow employs nearly 100 people, about 70 of whom are based in Israel, operating from offices in Israel and the United States.

Glow focuses on endpoint security, protecting the computers and devices employees use to access organizational systems. The company highlights how AI adoption has transformed cybersecurity, shifting threats from servers and networks to employee devices. Attackers now use AI to identify and exploit vulnerabilities faster, reducing the response window from days or weeks to hours. Glow’s AI-driven platform continuously learns an organization’s environment, security policies, and user behavior to identify safe AI tools and block risky ones, aiming to reduce threat exposure without limiting AI usage. The platform also addresses software risk management, supply chain security, and device management.

Roy Tigger emphasized the need for a preventative approach in the AI era, moving away from traditional reactive security models. He also noted a market shift toward fewer, broader cybersecurity vendors rather than many specialized solutions. Glow currently serves dozens of enterprise clients, including Fortune 500 companies in healthcare, retail, and financial services, with paying customers and others in deployment phases. Tigger stated the company’s goal is to build a significant, independent player in cybersecurity rather than pursue a quick exit, leveraging Israel’s matured cyber ecosystem to target long-term market leadership.
