Our Story

Why We Started

Too many small businesses were getting the same poor IT experience: slow support, reactive firefighting, and security treated as an afterthought. Or worse, they were paying enterprise prices for cookie-cutter solutions that didn't fit their needs.

After over 15 years working in IT and 5 years specialising in cybersecurity, we saw firsthand how proper security and proactive IT management could transform a business. We also saw how often smaller companies were underserved, left vulnerable while larger firms got all the attention.

"Every business deserves IT that just works, and security that actually protects, not just a checkbox exercise."

Blue Icon was founded to bring enterprise-grade expertise to London's growing businesses, without the enterprise price tag or complexity. We believe that security shouldn't be a luxury reserved for large corporations. It should be the foundation every business builds on.

Our Principles

What We Believe

These aren't corporate buzzwords, they're the principles that guide every decision we make and every service we deliver.

Security First

Security isn't a bolt-on service, it's built into everything we do. From day one, we design systems with protection in mind. It's why we hold CISSP certification, and why we won't cut corners on security to save time.

Proactive, Not Reactive

We don't wait for things to break. Through monitoring, maintenance, and planning, we prevent problems before they affect your business. You shouldn't have to think about IT, that's our job.

Plain English

Technology doesn't have to be confusing. We explain things clearly, without jargon, so you can make informed decisions. If we can't explain it simply, we don't understand it well enough.

Partnership, Not Vendor

We're not here to sell you things you don't need. We succeed when you succeed, so our advice is always in your best interest, even if that means recommending against a purchase.

Right-Sized Solutions

Enterprise tools aren't always right for growing businesses. We find the right fit for your size, stage, and budget, solutions that scale with you without overcomplicating today.

The Team

Who You'll Work With

When you work with Blue Icon, you work directly with experienced professionals, not a rotating cast of junior support agents.

Founder & Technical Director

CISSP

After 15+ years in IT and 5 years specialising in cybersecurity, I have learned that security gaps often appear in the places we least expect. Many well-meaning IT teams simply are not trained to spot every vulnerability, and that is not a criticism, it is the nature of an ever-evolving threat landscape.

Blue Icon was born from a simple moment of honesty: a friend in the MSP world admitted his own tech team could not handle a client's security needs and asked if I could step in. That first contract became the foundation for everything Blue Icon does today.

My focus is on seeing the full picture: understanding where systems connect, where they are exposed, and how to strengthen them before problems arise. Rather than routing you through layers of support, I work directly with clients so nothing gets lost in translation.

I hold the CISSP certification, the globally recognised gold standard in cybersecurity. It is a credential trusted by defence, finance, and enterprise security teams worldwide, and it reflects the rigorous, security-first approach I bring to every engagement.

Many of my clients are growing businesses in London who have hit a familiar wall: they are pitching for larger contracts, but prospects want to see proper security credentials first. I help them get there, not just ticking boxes, but building the foundations that let them compete and win.

My approach is simple: relationships first, honest advice, no hidden agendas. I am vendor-agnostic because I have seen too many MSPs turn into licence mills, pushing subscriptions for the commission rather than the client's benefit. I care about privacy and I favour open-source thinking wherever it makes sense. If there is a better, leaner solution, I will tell you.

Outside of work, you will find me at the boxing gym, behind the wheel of something fast, or deep into a Total War campaign. Chelsea matchdays remain non-negotiable. I have always been drawn to strategy, speed, and systems, whether that is on screen, on the road, or protecting client networks.

Co-Founder & Customer Success Director

CanonGoogle

Julien brings over a decade of experience in customer relationships, with roles at Canon and Google shaping his approach to client success. He understands that technology is only valuable when it genuinely serves the people using it, and that great service means more than just solving tickets.

He joined Blue Icon to complement the technical side of the business with the skills that keep it growing: sales, marketing, and client relationship management. While Marc focuses on security and infrastructure, Julien ensures the business runs smoothly and that every client feels looked after from first conversation through to renewal.

His focus is on building lasting partnerships, not transactional support. Julien takes the time to understand each client's business, their goals, and the challenges they face. That understanding allows him to provide guidance that is strategic, not just reactive.

At Blue Icon, Julien ensures every client receives personalised attention tailored to their unique situation. Whether it is onboarding a new team, navigating a complex project, or simply being a reliable point of contact, he is dedicated to making the experience as seamless as possible.

Outside of work, you will find Julien on the football pitch or glued to the F1. Despite Julien's questionable loyalty to Arsenal, we manage to keep the partnership running smoothly.
