One of the clearest signals we get at Operator Collective is when one of our own Operator LPs decides to go build something instead of just advise on it. Emily Heath, the CISO who sat on Wiz's board through its $32 billion acquisition by Google and ran security for United Airlines and DocuSign, just did exactly that when she joined Glow as COO.
Today, Glow announced it's stepping out of stealth with $180 million in funding at a $1.2 billion valuation led by Sequoia, Cyberstarts, Greenoaks, and Redpoint, with participation from us and others.
The Company
Any device employees work on is the “endpoint”. Laptops, desktops, servers, virtual machines, etc. Securing it is different from securing the network or the cloud perimeter, because the endpoint is where a person actually clicks something, installs something, or connects an AI tool to get their job done. It's the ground floor of the company, and it's also where most of the risk starts. Glow builds a platform that keeps track of everything running on those devices: every user, every piece of software, every AI app included. Then it puts AI agents to work finding the risky stuff and fixing it automatically. The platform currently analyzes more than 90,000 unique software components, flags vulnerabilities and misconfigurations, and ranks them by how much damage they'd actually cause if exploited. Then it takes action instead of filing a ticket for someone to get to later.
Why You Should Pay Attention
The endpoint used to be a fairly straightforward place to secure. Install antivirus, patch things on a schedule, move on. AI changed that. Employees are downloading AI tools, connecting agents, and plugging AI straight into their daily work, often before security teams even know it's happening. According to Glow, regular AI usage on corporate devices jumped from 15% to 45% in just a year. That's tens of thousands of new pieces of software showing up on company laptops, most of it never reviewed by anyone.
Attackers are moving fast too. They now have access to seriously capable AI models of their own, so weaknesses that used to sit around for weeks can get found and exploited almost instantly.
Most endpoint security tools were built for the old version of the problem. Something bad happens, the tool detects it, then someone responds. That model doesn't hold up when the endpoint is changing by the hour. Glow flips the order: it decides what's allowed to run before it gets the chance to cause damage, which is exactly the shift the endpoint security category needs right now.
The Details
Every device, user, and piece of software gets inventoried automatically, so nobody's chasing down spreadsheets to figure out what's actually installed across the company. From there, LLM-powered agents dig into each of those 90,000+ software components, looking for vulnerabilities and misconfigurations specific to each app.
Glow then ranks what it finds by actual business impact instead of a generic severity score, and can act on its own to remove or restrict what shouldn't be there, based on policies your security team sets. The goal is to shrink the attack surface automatically, instead of asking a stretched security team to chase every alert by hand.
Why We're Invested
Glow was founded by CEO Roi Tiger, alongside CTO Omer Singer and VP of R&D Ophir Arie.
Roi's an incredible repeat founder - he built Onavo, sold it to Facebook in 2013, then spent nine years at Meta running engineering for Commerce across the company. He's paired his experience with a team that's lived this problem from the other side. Omer ran cybersecurity strategy at Snowflake, Ophir led R&D at Claroty, and our own Operator LP Emily Heath came on as COO after running security for two major enterprises and sitting on Wiz's board through its acquisition.
Glow has already landed enterprise customers in healthcare, retail, and financial services even before coming out of stealth. Endpoint security is a crowded field, and most of the incumbents are still playing defense after the fact. Glow is betting that prevention at the endpoint becomes the standard way this gets done. If that bet plays out, Glow ends up defining what the endpoint security category is supposed to do next.
What's Next
The funding goes toward growing Glow's go-to-market team in the US and expanding Glow Labs, the company's research arm. If you're heading to Black Hat USA in Las Vegas, Glow will be showing off the platform at the House of Glow, House of Blues Courtyard, from August 3 to 5.
