Founded in 2012. Still led by the same CISSP-certified engineer who started it.

Fusion Computing started in 2012 when Mike Pearlstein left a career in enterprise IT to build the kind of managed service provider he’d want to hire. The thesis was straightforward: most MSPs serving Canadian SMBs were either too small to handle real security work or too large to give clients direct access to senior people. There was room in the middle for a provider that could do both.

The first few years were a one-person operation , Mike handling everything from helpdesk tickets to firewall configs to quarterly business reviews. Growth was deliberate. Every new client was a commitment to own their entire IT environment, not just the easy parts.

The pandemic changed the math

When COVID-19 sent every office home in March 2020, businesses that had been running on duct tape suddenly needed real remote infrastructure , secure VPNs, endpoint protection, cloud identity management, and someone who would actually pick up the phone. Fusion grew during this period because the model was already built for remote-first support. The team expanded, the client base grew beyond Toronto into Hamilton and Vancouver, and the operating model held under pressure.

CIS as a Service

One of the most commercially successful developments at Fusion has been the CIS-as-a-Service offering , a structured cybersecurity program built on the CIS Controls framework that gives SMBs an auditable, insurer-friendly security posture without the cost of building it internally. It maps directly to client environments, gets implemented by the same team that handles day-to-day support, and produces documentation that holds up when insurers or auditors ask questions. This offering has become a core differentiator.

The team has grown well beyond the founder. Meet the current Fusion Computing team → You can also review the technology partners and certifications that shape the way Fusion builds and supports client environments.

If you’re comparing MSPs, you’re probably trying to answer a simple question: can the people behind the logo actually keep their promises? You don’t need a slick pitch if the team can’t carry the work, and you shouldn’t have to guess who’ll own the next step. Fusion’s approach is to show the leadership, the standards, and the certifications upfront so you can decide whether it’s a fit before you commit.

That matters because businesses don’t buy brochures; they buy continuity. When something changes, you want to know who’ll respond, what they’ll use, and how quickly they’ll move. That’s the difference between a vendor that talks and a partner that stays accountable.

Mike Pearlstein holds the CISSP (Certified Information Systems Security Professional), a widely recognized cybersecurity certification that requires five years of documented professional security experience and ongoing continuing education. ISC2, the organization that administers the credential, maintains strict experience and ethics requirements.

What this means practically: when a client gets a cybersecurity insurance questionnaire, they don’t get handed a template and told to fill it out. When a vendor recommends a new EDR tool, there’s someone in the room who can evaluate whether it actually closes a gap or just adds another dashboard. When a breach happens , and one did, to a client who came to Fusion mid-incident , the response runs under someone with the training and judgment to manage it.
