Choose the security support your business needs
Managed cybersecurity combines ongoing threat monitoring, investigation, response and control improvements. Fusion Computing delivers a CISSP-led program for Canadian businesses, usually with 15 to 200+ users, that need outside security capacity or a partner beside their internal IT team.
The choice depends on who will own the work after the first assessment. A defined project can answer a specific question; an ongoing program carries agreed monitoring and response duties. For a personal account problem, use our cybersecurity help for individuals guide.
Which security model fits your business?
On a phone, swipe the table sideways to compare the options.
| Decision | Fusion Computing managed cybersecurity | Defined assessment or project | In-house security team |
|---|---|---|---|
| Primary job | Fusion Computing carries the security operations in your ongoing scope. | A specialist delivers the work and findings agreed for that engagement. | Your employees own the security program. |
| Alerts after the project ends | 24/7 monitoring and response responsibilities are defined in the program. | Ongoing monitoring requires a separate arrangement. | Your team investigates or arranges outside cover. |
| Fit | You need continuing security capacity, with or without an internal IT lead. | You need an assessment, incident exercise or a specific improvement. | You can staff and manage the required security work. |
| Buying basis | Per-user subscription, with systems, licensing and responsibilities agreed. | A written scope, deliverables and project price. | Staffing, tools and outside support you choose. |
Indicative managed cybersecurity cost
CAD $180 to $250+ per user per month, depending on scope and requirements. MSSP Advanced starts at $180. The CIS-Aligned package is about $230 and includes Microsoft 365 Business Premium or an equivalent licensing arrangement. The written proposal identifies covered systems, response duties, licensing and any separate project work.
Already have an IT lead? A co-managed IT engagement can carry agreed security and escalation work beside your team. vCISO advisory supports strategy and reporting. For a defined project, request a cybersecurity risk assessment or incident-response discussion.
What managed cybersecurity services include
The program is built around the systems and response responsibilities in your scope. These are the functions Fusion Computing can carry, with documented handoffs to your internal staff. For the broader IT function, see managed IT services.
24/7 MDR and EDR Monitoring
Endpoint detection and managed threat response cover the devices in the agreed scope. An analyst investigates alerts and escalates confirmed findings under the response plan.
Email Security and Phishing Protection
Most breaches start with an email. We block phishing, spoofing, and fake links with DMARC, DKIM, and SPF plus real-time scanning. Email security is part of every engagement.
Identity and Access Management
Multi-factor authentication on every account. Conditional Access for Microsoft 365. KeeperSec for password and secrets management. When someone leaves, their access ends that day. No orphaned accounts sitting open.
Network Security
Fortinet firewalls, network monitoring, and DNS filtering that blocks bad domains before they reach your team. VPN, remote access, and cloud security for Azure and Microsoft 365. Reviewed at onboarding and again each quarter.
Vulnerability Management and Pen Testing
Regular scanning inside and out. Findings rank by what an attacker could actually use, then get fixed and verified. Maps to CIS Controls v8.1, NIST CSF, and CyberSecure Canada. Run it standalone or as step one of a managed program. See what a network penetration test finds and what it costs.
Incident Response
When something goes wrong, you need a plan that already exists. Our incident response services spell out who does what, how fast, and what gets escalated. After an incident, we run forensics, find the root cause, and close the gap. See it in action: ransomware recovery case study.
Compliance and Reporting
We map your controls to CIS Controls v8.1, NIST CSF, CyberSecure Canada, SOC 2, PIPEDA, and PHIPA. Monthly security reporting covers what changed, what we fixed, and what is next. Client and insurer security reviews keep raising the bar, so being ready now saves you later.
Backup and Disaster Recovery
Immutable, air-gapped backup infrastructure with documented recovery procedures and periodic restore testing. When ransomware hits, the question is not whether you have backups. It is how fast they restore and whether the attacker can reach them.
Compliance evidence belongs beside the controls
Fusion Computing uses CIS Controls v8.1 to organize security work and supports documentation for NIST CSF, PIPEDA, Ontario PHIPA and SOC 2 readiness where relevant. Your privacy, legal and audit advisers determine the obligations and assessment decisions that apply.
Why Canadian businesses choose Fusion Computing for cybersecurity
“Most Canadian SMBs don’t fail at cybersecurity because they bought the wrong tool. They fail because MFA wasn’t fully rolled out, patch cadence had drifted, and no one had rehearsed the incident response plan. We engineer those three fundamentals first, before anyone pays us for threat detection.”
CISSP Leadership
Your program is led by a CISSP who knows what auditors, insurers, and regulators expect. Mike sets the CIS Controls v8.1 baseline every Fusion Computing client inherits and signs off on every incident response plan.
Canadian-owned and Canadian-operated
Fusion Computing is Canadian-owned and Canadian-operated. We have served Canadian businesses since 2012, with regional offices in Toronto, Hamilton and Metro Vancouver.

“The assessment found an admin account with domain-level rights that had been inactive for four years but was still open. One phishing email away from a full breach. We never would have caught that on our own.”
Mark S., CFO, professional-services firm
“I’ve done post-incident reviews for six companies this year where the breach started with a compromised vendor credential. Not a zero-day, not a sophisticated attack. A vendor whose password hadn’t been rotated in three years. That’s what we fix first.”

How managed cybersecurity works
The engagement moves from discovery to a scoped assessment or an agreed security program. Timing follows your environment and change plan.
30-Minute Discovery Call
We discuss your business need and existing security coverage. Request a call here.
Security Assessment
A separately scoped, paid assessment maps evidence from your environment against CIS Controls v8.1 and identifies agreed areas for improvement.
Ongoing Protection
After the scope is signed, we configure the agreed tools, monitoring and escalation procedures. Activation dates depend on the environment and change plan. Reviews track incidents and control improvements.
Security signals from the systems in scope reach the monitoring team for investigation and escalation. Confirmed threats follow the agreed containment and recovery procedures. Fusion Computing targets a one-hour acknowledgement of critical incidents; the proposal defines response responsibilities and on-site arrangements across Toronto, Hamilton and Metro Vancouver.

IBM’s 2026 Cost of a Data Breach report reports a CA$7.11 million average for Canadian organizations in its study. The global study examined breaches at 602 organizations between March 2025 and February 2026. That average provides context, not an estimate of what a particular small business would lose. Prioritization still starts with your systems, data and ability to recover.

Common questions about managed cybersecurity
Answers from our CISSP-led security team. Need more detail? Request a discovery call and we’ll walk through your specific situation.
What is the difference between MDR, EDR, and a SOC?
EDR is endpoint detection and response software on devices. A SOC is the security operations team that investigates alerts. MDR is the managed service that combines monitoring, investigation and response. Fusion Computing brings those functions together under CISSP-led oversight, with covered systems and response actions defined in the engagement scope.
How fast do you respond to a security incident?
Fusion Computing targets a live human acknowledgement of critical incidents within one hour. The engagement defines monitoring coverage, escalation contacts, containment authority and on-site arrangements. Our reported 93% first-contact resolution applies across support tickets; it is not a promise that a security incident will be fully contained or recovered within that time.
Which compliance frameworks do you support?
Fusion Computing uses CIS Controls v8.1 to organize security work and supports documentation for NIST CSF, PIPEDA, Ontario PHIPA and SOC 2 readiness where relevant. The engagement defines policies, technical controls and evidence to prepare. Your privacy, legal or audit advisers determine the obligations and assessment decisions that apply to your organization.
