From Aeronautics to Internet Security - Via MIT and 27 Years of Enterprise Software

Start with the resume and you miss the point. Remko Vos studied aeronautical engineering at Delft - the rigorous, physics-first discipline of people who design things that have to work. Then he got an MBA from MIT Sloan and proceeded to spend nearly three decades building product organizations at companies like Siebel Systems (acquired by Oracle), Intelliden (acquired by IBM), and Trilliant before landing at Comcast's Xfinity division. When he was recruited to lead CUJO AI in April 2022, he wasn't walking into a stranger's house. He had been a CUJO AI customer for years while at Comcast, arguing for the platform from the buyer's seat.

That's a different kind of CEO - one who knows exactly what it's like to be on the other side of a sales call, to fight internal budget battles for your vendor, and to feel the product gaps firsthand. It also means he arrived with no illusions about what CUJO AI actually does well and where it still had work to do.

What CUJO AI Actually Does

The pitch sounds abstract until you think about your own house. Your router sees every device. Your smart TV, your thermostat, your kid's gaming console, your visiting relative's phone - all of it passes through a single chokepoint before hitting the internet. CUJO AI sits at that chokepoint, but not in your home. It sits at the ISP level, embedded inside the network operators who serve millions of customers simultaneously.

The platform identifies devices - not just "there's a connected device here" but which device, what it is, what it normally does, and when it's behaving strangely. That device intelligence feeds security decisions, parental controls, and network optimization in real time. At scale, that means monitoring more than 3 billion connected devices and blocking over 17,000 threats per minute. The 60 million homes the company now protects represent a subscriber base larger than most countries' populations.

Vos inherited a platform already serving nearly 2 billion devices. He's grown it by 50% since taking the chair - and landed Tier-1 carrier wins including T-Mobile USA and EE that signal where the market is heading. ISPs are no longer just selling bandwidth; they're selling security, privacy, and peace of mind as part of the bundle.

The Unusual Career Geometry

Two degrees that don't obviously connect. Aeronautical engineering at TU Delft trains you to think in systems: complex, interdependent, where failure in one component cascades across the whole. An MIT Sloan MBA trains you to think in markets: who buys, why they buy, and how you price what they need. That combination turns out to be precisely the toolkit for enterprise cybersecurity software, where you're building deeply technical platforms for buyers who make decisions in boardrooms, not server rooms.

The 27-year career arc has a quiet coherence once you look backwards. Siebel Systems was enterprise CRM before Salesforce rewrote the category. Intelliden built network configuration management tools. Trilliant built smart grid and smart city infrastructure. Comcast built the broadband experience platform for millions of American households. Each role layered on: telecom understanding, network architecture, product management at scale, service-provider domain knowledge. CUJO AI, at the intersection of IoT security and carrier networks, required someone who had touched every corner of that Venn diagram.

The ISP Security Thesis

Vos has been consistent about where he thinks the future of home network security lives: with the carriers, not the consumers. Consumer security products require installation, configuration, renewal, and attention - the exact behaviors most households don't provide. ISP-level security is invisible, always-on, and doesn't ask anyone to remember a password. The customer doesn't know it's working. The network operator does.

This is not just a go-to-market choice - it's a structural argument about where leverage exists in the security stack. In a world where connected device counts are doubling every few years, the only scalable answer runs through the ISP. And with T-Mobile USA, EE in the UK, and a growing roster of operators across North America and Europe, CUJO AI has placed its bets with the right partners.

The FCC's 2026 decision to add foreign-made home routers to its "Covered List" brought Vos out publicly with a sharp observation: cybersecurity keeps losing to industrial policy. The covered list expansion looks like security action but lands primarily as trade policy. It was the kind of candid policy critique that signals a CEO who has spent enough time in Washington-adjacent rooms to know how decisions actually get made - and who isn't afraid to say so.

The World Stage

You don't get invited to the World Economic Forum by accident. Vos contributed to WEF's "Avoiding Digital Lockdown: Securing Smart Cities" session - the rare kind of topic where aeronautical-engineering-level systems thinking actually helps. Smart cities are, at their base, networks of connected devices operating at urban scale. The failure modes are serious. The attack surface is enormous. The policy frameworks are embryonic.

At MWC 2025, he participated in the Thought Leader Insight Series with his key takeaways from the year's largest mobile industry conference. At the North American Lithuanian Business Forum in 2026, he was on stage discussing AI and entrepreneurship. These aren't just brand-building appearances. For a B2B cybersecurity platform company that sells to telcos, being the CEO who shows up in these rooms matters in ways that no amount of digital advertising can replicate.
