Toronto Cybersecurity Services

Managed cybersecurity aligned to CIS Controls v8.1, delivered by a CISSP-certified team protecting Toronto and GTA businesses since 2012.

Toronto Businesses Can’t Afford to Leave Cybersecurity to Chance

Fusion’s managed cybersecurity services identify real risk, close gaps in your defences, and give Toronto businesses a defensible security baseline — aligned to CIS Controls v8.1 and backed by CISSP-certified leadership.

  • Our Toronto-based team delivers 24/7 managed detection and response (MDR) from a local SOC — no offshore outsourcing, no delays.
  • Endpoint detection and response (EDR, MDR, and XDR) across all devices — with identity threat detection and response (ITDR) to catch credential compromise before damage spreads.
  • Our CEO holds the CISSP certification — the industry’s most respected security credential. Senior-level security judgment guides every engagement, not just junior technicians.
  • PIPEDA compliance and Canadian data sovereignty built into every service. Your data stays in Canada, managed by Canadians, and meets Bill C-26 regulatory readiness requirements.
  • Multi-factor authentication enforcement (MFA), conditional access policies, and email security hardening (DMARC/DKIM/SPF) to shut down phishing and unauthorized access.
  • Secure configuration hardening based on CIS Benchmarks, with quarterly security posture audits and vulnerability scanning to ensure your defences stay current — not just set and forgotten.

Want to see where your security gaps are? Book a free 30-minute cybersecurity assessment — we’ll review your current controls, recovery gaps, and immediate priorities. No pressure, just clear next steps.

What managed IT support should actually cover

Managed IT support combines responsive help desk with proactive monitoring, patching, vendor coordination, endpoint protection, and operational planning. The goal is not just to close tickets. The goal is to keep your team productive, reduce recurring issues, and give the business a more stable IT baseline.

30 Days to Remediate Critical Gaps | Unpatched Servers Found in Week 1 | Security Baseline Rebuilt Without Business Disruption

“We’d been with our previous IT provider for six years and thought everything was running well enough. Within the first week of Fusion’s onboarding, they found unpatched servers, no working backups, and admin credentials that hadn’t been changed since 2019. It was genuinely alarming.”

Testimonials

See why top employers and small business leaders say Fusion is the Best IT Company in Toronto

"I got the call no business owner wants - our systems were locked and there was a ransom demand on every screen. I called Fusion in a panic at 9pm on a Friday. They had someone working on it within the hour. By Monday morning our team walked in, sat down, and got back to work like nothing happened. Every file recovered. No ransom paid. I don't even want to think about where we'd be if we'd been with our old provider when that happened."

Sandra M.

"One of our staff had their credentials phished through a fake Microsoft login page. Fusion's monitoring picked up the suspicious login - from overseas, at 2 in the morning - and locked the account before whoever had the password could do anything with it. They called us first thing to walk us through what happened, reset everything, and added extra protections. If that had gone undetected even a few hours longer, they would have had access to our client files. I sleep better knowing someone's actually watching."

Thomas W.

"We went from 35 employees to 70 in under a year after landing two major contracts. Every new hire needed a laptop provisioned, accounts set up, security configured, and access to our project management stack - usually within 48 hours of the offer letter going out. Fusion handled every single onboarding without us having to micromanage it. Our HR team just sends them the details and it's done. That kind of responsiveness let us focus on growth instead of wrestling with IT logistics."

Priya R.

"We'd been with our previous IT provider for six years and thought everything was running well enough. Within the first week of Fusion's onboarding, they found unpatched servers, no working backups, and admin credentials that hadn't been changed since 2019. It was genuinely alarming. Fusion fixed all of it in the first 30 days and built us an actual security baseline. Looking back, we were one bad click away from a catastrophe and didn't even know it."

Derek K.

"We've been with Fusion since 2019 and the thing that still surprises me is how much they remember about our business. I don't have to re-explain our setup every time I call. They know our systems, they know our team, they know our busy seasons. Last year they proactively recommended we migrate a legacy server before it became a problem - saved us from what would have been a very expensive emergency. That's not a vendor relationship. That's a partner who's paying attention."

Michael T.

"We'd been to three different vendor presentations about AI and Copilot and every single one assumed we had a dedicated IT team, a data lake, and a six-figure budget. We have 40 people and a bookkeeper. Fusion came in, looked at what we actually do every day, and found three processes where automation would save us real hours every week. No jargon, no massive investment. They deployed Copilot for our leadership team and built a simple workflow automation that cut our month-end reporting from two days to four hours. That's the kind of AI that actually matters."

Rachel D.

"It is refreshing to work with a technology vendor that is reactive in an expedient manner to our needs as a business. Fusion takes the time to learn what your current and future goals are, offers options to help you achieve them, and make you feel like your business is valued. This partnership has allowed us to reinforce the security of all our operations, protect our customers, and increase our overall efficiency. What a great TEAM!"

Naomi Clarke

Idea Factor

"I have worked closely with Fusion over the past year and I have to say that these guys are great. They manage our Infrastructure, Virtual Machines, Backups, Security, implemented our Cloud Solution with O365 and are our IT Support for staff and desktops. They came highly recommended so I am doing the same for you."

Judie Law

"Fusion Computing has been the best IT Services provider we’ve ever had. Their managed IT services offering covers all 4 of our JP Motors locations bumper to bumper. They take the time to work with us to help us understand our budget and provide solutions from help-desk through to IT Strategy. Highly recommended!"

Why Toronto Businesses Choose Fusion Cybersecurity

Managed Cybersecurity Built Around CIS Controls

Fusion Computing delivers managed cybersecurity services aligned to CIS Controls v8.1 for Canadian businesses. We harden identities and endpoints, improve backup and recovery readiness, reduce ransomware exposure, and help you respond confidently to cyber insurance and vendor security questionnaires.

Unlike most Toronto MSPs that bolt on basic antivirus and call it cybersecurity, Fusion builds your security posture from the framework up. CISSP-certified leadership, 24/7 SOC monitoring by local analysts, and a defensible baseline — not a patchwork of disconnected tools.

24/7 Security Operations from Our Toronto SOC

Our security operations team is based in Toronto — not outsourced offshore. When a threat is detected at 2 AM, the analyst responding knows your environment, your business, and your industry. Our CISSP-certified leadership means every escalation gets senior judgment, not a script.

Stop Ransomware, Phishing, and Endpoint Threats Before They Spread

We deploy layered endpoint protection — EDR, MDR, and XDR — combined with AI-powered DNS filtering, email security hardening (DMARC/DKIM/SPF), and identity threat detection to neutralize threats before they reach your users.

Quarterly security posture audits and continuous vulnerability scanning ensure your defences evolve as the threat landscape changes. When we find gaps, we close them — not just report on them.

Recovery-Ready Infrastructure for Toronto Businesses

Ransomware doesn’t just encrypt files — it shuts down operations. Fusion’s backup and recovery architecture is designed to get your Toronto business back online within 60 minutes of a critical incident, with tested restore procedures and immutable backups that ransomware can’t touch.

Multi-factor authentication, conditional access enforcement, and least-privilege access controls ensure that even if credentials are compromised, lateral movement is contained before damage spreads.
