Glow Security
AI-native endpoint security that finds and controls every piece of software on your fleet.
Overview
Glow Security: prevention-first security for software you didn't know you ran
Glow Security is an AI-native endpoint security platform built around a blunt claim: existing tools cannot see most of what actually runs on enterprise endpoints. The company's research puts more than 12,000 unique software pieces in an average organization, 67% of them invisible to current tooling, and 30% of AI agents operating without guardrails. Glow continuously discovers all of it, researches and validates each piece automatically, and uses autonomous remediation agents to prevent issues rather than respond to them.
Founded in 2025 by Roi Tiger (previously VP of Engineering at Meta), Omer Singer (former head of cybersecurity strategy at Snowflake), and Ophir Arie (former VP R&D at Claroty), Glow left stealth on July 22, 2026 as a born unicorn: $180M in cumulative funding at a $1.2B valuation, led by Sequoia, Cyberstarts, Greenoaks, and Redpoint, with signed customers including Qualtrics, Fanatics, CAVA, BMC Software, Antares Capital, Xactly, and Hospital Sisters Health System.
Key Features
- Asset Intelligence: continuous discovery of endpoints and every piece of software on them
- Automatic research and validation of each discovered software component
- Autonomous remediation and prevention agents with adaptable policies
- Safe AI Adoption module for visibility and control over shadow AI
- Prevention-first posture — the company cites a 28-day average time-to-zero critical issues
- Glow Labs in-house research arm
Ideal Use Case
A CISO who suspects — correctly, per Glow's numbers — that the endpoint fleet runs thousands of software components nobody inventoried, including AI tools employees adopted on their own, and who wants discovery plus autonomous cleanup instead of another alert queue.
How Glow Security differentiates
Incumbent EDR (CrowdStrike, SentinelOne, Microsoft Defender) detects and responds to threats; Glow's pitch is that these tools miss the majority of endpoint software entirely and do not govern AI agents at all. It pairs asset-intelligence-style discovery (Axonius, Sevco territory) with autonomous prevention in one platform. Production credibility: $1.2B valuation at stealth exit — one of 2026's few security born-unicorns — with named enterprise logos across finance, healthcare, retail, and software before launch day.
FAQ
Is Glow Security an EDR replacement? Glow positions as prevention-first software control rather than detect-and-respond; in practice enterprises run it alongside existing EDR while it takes over software discovery and remediation.
What is the Safe AI Adoption module? A dedicated capability for finding shadow AI — unmanaged AI tools and agents on endpoints — and applying guardrails to them.
Who is behind Glow? Ex-Meta VP Engineering Roi Tiger, ex-Snowflake security strategist Omer Singer, and ex-Claroty R&D lead Ophir Arie, backed by Sequoia, Cyberstarts, Greenoaks, and Redpoint.
How much does Glow cost? No public pricing; enterprise sales via glow.io.
tl;dr
Glow Security launched as a $1.2B unicorn with a sharp thesis: endpoint security's real gap is the 67% of software nobody can see — so discover everything, validate it, and let AI agents fix it before it becomes an incident.
