Glow Emerges from Stealth with $180M to Redefine AI-Native Endpoint Security

As AI rapidly transforms the enterprise, endpoint security is facing one of its biggest challenges yet. The emergence of Glow from stealth with $180 million in funding at a $1.2 billion valuation marks one of the largest cybersecurity seed and Series A rounds in recent years, and a strong signal that investors believe AI will fundamentally reshape endpoint security.

Congratulations to Roi Tiger, Omer Singer, Ophir Arie, Emily Heath, and the entire Glow team on this remarkable milestone.

Led by Sequoia Capital, Cyberstarts, Greenoaks, and Redpoint, with participation from Index Ventures, Swish Ventures, Lux Capital, Operator Collective, and Holly Ventures, the funding reflects exceptional confidence in Glow's vision for the future of enterprise security.

Why This Funding Matters

The way employees use enterprise endpoints has changed dramatically. AI assistants, copilots, autonomous agents, and third-party AI applications are now becoming part of everyday workflows, often faster than security teams can evaluate and govern them.

AI usage on corporate devices has grown rapidly over the past year, creating new risks that traditional endpoint security solutions were never designed to address.

Glow believes that defending modern endpoints requires a prevention-first approach, in which AI continuously identifies risks before they can be exploited, rather than responding after an attack has already occurred.

Rethinking Endpoint Security for the AI Era

Traditional endpoint security has focused on detecting threats and responding once suspicious activity is identified.

However, AI-powered attackers now operate at machine speed, making reactive security increasingly difficult to sustain.

Glow is building an AI-native endpoint security platform powered by intelligent agents that continuously:

• Map the endpoint environment
• Analyze risk in real time
• Enforce security policies automatically
• Control applications and AI activity without disrupting users

Rather than adding friction to the employee experience, the platform is designed to help organizations maintain security while enabling business productivity.

A Founding Team Built for Enterprise Scale

Glow's leadership team brings together deep expertise from some of the world's most influential technology and cybersecurity companies.

CEO Roi Tiger spent nine years as Vice President of Engineering at Meta, while CTO Omer Singer previously led Cybersecurity Strategy at Snowflake. VP of R&D Ophir Arie helped build Claroty's research and development organization, and COO Emily Heath served as CISO at both United Airlines and DocuSign while also sitting on Wiz's board during its growth journey.

That combination of engineering, cybersecurity, and enterprise leadership gives Glow a strong foundation as it enters an increasingly competitive market.

What This Signals for Cybersecurity

Glow's funding reflects a much broader trend across the cybersecurity industry.

It follows several major investments in AI-native security companies, reinforcing that investors and enterprise buyers increasingly view AI as the foundation of next-generation security architecture.

For CISOs, this shift is equally significant. As AI adoption accelerates, organizations will need endpoint security platforms capable of understanding, governing, and protecting AI-powered environments at enterprise scale. The future of endpoint security will depend less on reacting to attacks and more on preventing them through continuous intelligence and automation.

Looking Ahead

Glow enters the market at a time when enterprises are rapidly redefining how endpoint security should operate in an AI-driven world.

With $180 million in funding and an experienced leadership team, the company is well positioned to help organizations move beyond traditional detection models toward proactive, AI-native endpoint protection.

Glow's emergence from stealth highlights a growing reality in cybersecurity: protecting endpoints in the AI era requires security platforms built for prevention, automation, and real-time decision-making from the ground up.

Execweb congratulates Glow on this milestone. The $180M funding round reflects growing confidence in AI-native endpoint security and the industry's shift toward prevention-first security architectures designed for the next generation of enterprise threats.
