Our Mission

We build bridges between our Clients and our collaborative team of experts to remove the inefficiencies and threats of inadequate IT and cybersecurity, thereby liberating our Clients to focus on what matters most to them.

We believe technology should be a liberator for our Clients, not a threat.

The Power of TEAM

We are a collaborative team of highly-trained IT and Security professionals with over a millennium of combined experience providing solutions for Small and Mid-sized Enterprises.

Every red NerdMobile, and every red shirt comes with the combined security first, SME-focused experience and expertise of the entire worldwide collaborative team of Nerds. You hire one, you get us all. Whatever IT issues you come up against, you can bet there is a Nerd who’s seen it before and devised a solution for it.

Turning the Model Upside Down

Traditional IT companies have always looked at security as an add-on, one of the pieces of the puzzle. We know that with the current state of the internet landscape, and the dangers it contains, security needs to be your top IT priority, the very first piece of the puzzle. We use our experience and leading-edge technology to ensure your valuable systems and data are as secure as they possibly can be. Then, combined with the strength of our strategic and industry-leading partners, we take care of the rest.

Nerds in the Community

We understand the importance of giving back to the communities in which we serve and encourage every Nerd to do so. Among their charitable efforts is the annual “Fill the Beetle to Feed the People” food drive. To date, this event has collected over 100 tonnes of food to donate to local food banks.

Our Beginnings

In 1995 in London, Ontario, Canada, two self-proclaimed nerds (John Harbarenko and David Redekop) joined forces with the aim of solving people’s “tech-aches” by helping them turn their technology from a burden to an asset. And these guys came right to your door to do it. Back when monitors weighed 80lbs, this was a big deal!

This type of dedicated support service allowed people to concentrate on what matters most to them, which resulted in warm and positive Client feedback.

A Brief History: How Nerds On Site Grew Up

From a handful of guys driving around in the first NerdMobile servicing residential clients, we grew by adding Charlie Regan, our CEO (Capability Expansion Orchestrator), who facilitated the addition of passionate and experienced IT professionals to make us a global TEAM of experts. Through this expansion and our collaborative nature we evolved to become a trusted Cybersecurity and IT Solutions company for SMEs.

We continue to add Nerds who possess the experience, technical expertise and vision that allow us to proactively address your needs, ensure the security of your critical data and systems, and keep your networks running safely and efficiently.

Don’t let the cute cars fool you. We are serious about IT – even more so about security – with the tools and technology to protect your business that nobody else has.
