Israeli cybersecurity startup Glow emerged from stealth on Wednesday with $180 million in funding at a $1.2 billion valuation, launching an AI-powered platform designed to prevent security threats from reaching corporate devices.
Glow focuses on endpoint security, which protects the laptops, desktop computers, and other devices through which employees connect to corporate systems.
The platform uses specialized AI agents to continuously map an organization’s digital environment, analyze risks in real time, and automatically enforce security policies. The system determines which software should be permitted and which should be removed, seeking to prevent threats before they enter an organization.
The company was founded in 2025 by CEO Roi Tiger, who previously worked at Meta; CTO Omer Singer, formerly head of cybersecurity strategy at Snowflake; and vice president of research and development Ophir Arie, who previously held the same role at Israeli cybersecurity company Claroty.
Glow’s leadership team also includes chief product officer Arnon Joseph, who spent eight years at Meta, and chief operating officer Emily Heath.
Glow is already signing clients, addressing security threats
Heath previously served as chief information security officer at United Airlines and DocuSign and was a partner at Cyberstarts. She was also a member of Wiz’s board of directors through its acquisition by Google.
Glow said it had already signed enterprise customers in the healthcare, retail, and financial services sectors. The company said these customers were using its platform to adopt AI technology while strengthening, rather than weakening, their security systems.
“I sat in the CISO seat for a long time, and I can tell you the tools available to us were never built for what enterprises face today,” Heath said.
“Every enterprise wants to move faster with AI. The question isn’t whether they’ll adopt it; it’s whether security can keep up. That’s the challenge Glow is solving.”
The company argues that the rapid adoption of AI tools has transformed devices, such as computers and desktops, into an increasingly significant security vulnerability, as employees introduce new applications and AI agents into the workplace faster than security teams can examine and authorize them.
Verizon’s 2026 Data Breach Investigations Report found that regular use of AI tools on corporate devices, whether authorized or not, had risen from 15% to 45% in a single year.
Glow receives $180 million in funding
The funding was led by Sequoia Capital, Cyberstarts, Greenoaks and Redpoint Ventures, with participation from Index Ventures, Swish Ventures, Lux Capital and Holly Ventures.
Glow plans to use the funding to expand its go-to-market team in the United States and grow Glow Labs, the company’s research division.
The launch further highlights the outsized importance of cybersecurity to Israel’s technology sector and the country’s position as a global cyber power.
Israel had more than 500 active cybersecurity companies in 2024. Although those companies represented only 7% of the Israeli technology ecosystem, they attracted 38% of all tech investment, according to Startup Nation Central.
Israeli cybersecurity companies raised an additional $4.1 billion in 2025, with a median funding round size of $20 million.
The sector has also produced two of the largest deals in Israeli technology history: Google’s $32 billion acquisition of Wiz and Palo Alto Networks’ $25 billion acquisition of CyberArk.
