Why Do Markham Suppliers Face Tougher Security Reviews?

Because the companies they work with are large and heavily scrutinized. Markham hosts more than 400 Canadian head offices, and big organizations increasingly pass their security requirements down to every supplier through questionnaires, contract clauses, and audits.

The City of Markham lists IBM, AMD, Lenovo, Huawei, Honeywell, Johnson & Johnson, Honda, and Aviva among the organizations with major operations here. A small firm that services, supplies, or consults for any of them can expect questions about MFA, backups, incident response, and who has admin access. Answering those questions honestly is easier when the controls actually exist.

The good news is that the baseline isn’t mysterious. The Canadian Centre for Cyber Security publishes baseline cyber security controls for small and medium organizations, including an incident response plan, automatic patching, strong authentication, employee training, and backups. Most of what a supplier questionnaire asks maps directly to that list.

Not sure where you stand? Our guide to what a cybersecurity assessment actually covers explains what a real review should examine.

Basic Antivirus vs. Layered Cybersecurity in Markham

Many Markham businesses believe they’re covered because every laptop has antivirus. Here’s what that leaves out compared with a layered approach.

Antivirus Only Layered Security (ACT360)
Stolen passwords No protection MFA and sign-in monitoring
Spoofed or lookalike emails Often missed Filtering plus staff awareness training
Ransomware recovery Depends on untested backups Isolated backups with tested restores
Supplier questionnaires Hard to answer Documented controls and evidence
Who responds to an incident Unclear A written plan and a named team

What Does Cybersecurity Cost for a Markham Business?

ACT360 prices cybersecurity work after the free assessment, based on users, devices, and the gaps it finds. Ongoing security is included in managed IT plans at $80 to $150 CAD per user per month, and one-off remediation projects are quoted in writing.

The cheapest security improvements are usually the most valuable. Turning on MFA, removing unnecessary admin rights, and testing a backup restore often cost hours, not months. The things that raise the price are predictable.

  • Number of users, devices, and locations
  • Specific client, insurer, or regulatory requirements
  • Older systems that can’t support modern protections
  • Whether you want ongoing monitoring or a one-time fix

If an insurance renewal is driving the conversation, our guide to cyber insurance requirements in Ontario covers what underwriters typically ask.

Our Approach

A.C.T.I.O.N.

Security recommendations only make sense once we know what you’re protecting and who’s asking. That’s why every Markham cybersecurity engagement follows the same 6 steps.

Get an IT Readiness Assessment
A

Assess

A real review of your accounts, devices, email, backups, and payment processes, not an overnight scan emailed as a PDF.

C

Comprehend

We dig into why things are set up the way they are and where you’re headed over the next few years, so the plan fits your business, not a template.

T

Tailor

The recommendation is built from what we learned, with specifics, reasoning, cost, and what we’re deliberately not recommending yet.

I

Implement

Phased, not big-bang. Critical systems move first and get validated before anything else changes.

O

Optimize

Quarterly reviews cover outcomes, not ticket counts. You get recommendations you didn’t have to ask for.

N

Nurture

We build relationships with your team, not just the owner. Whoever picks up the phone already knows your setup.

How ACT360 Keeps Security Improvements Low-Risk in Markham

Financial

Cybersecurity work is scoped and priced after the free assessment, in writing. The 90-day exit clause belongs to Managed IT agreements, so it applies only if you choose a managed plan.

Switching

Nothing gets ripped out on day one. We document what you have, fix the highest-risk items first, and change the rest in phases.

Political

The Assess step produces a plain-language report you can take to partners or leadership before anyone signs anything.

Operational

A named contact, Adam or Jeffrey, who already knows your environment when you call.

Ownership

Accounts, documentation, and configurations stay yours, with admin access you control.

You won’t be handed off to a rotating helpdesk. Here’s who you’ll actually talk to.

The Team Values Behind ACT360’s Cybersecurity in Markham

Security is where Be a Problem Solver matters most. We look for the cause, not just the alert.

Group 30

Be the Client

We listen to our clients and other team members to understand the full scope of the requirements and goals. We put ourselves in your shoes as we design and build the processes, tools, and infrastructure that will make your team more productive.

Group (1)

Give the 360° Solution

Our goal is to give our clients the full solution, so your technology becomes a profit enhancer rather than a profit hindrance. That’s why we offer more than a service desk or IT support. We bring a vCIO, IT strategy, and process improvement to the table.

Group (2)

Frame

Always Looking Forward

We strive to deal with our mistakes as a team, learn from them, fix them, and then not look back and repeat them. We also aim to provide proactive and forward-facing solutions by identifying issues as soon as they’re spotted.

Group (3)

Working to Live, Not Living to Work

We want our employees to feel supported to take care of family and personal needs. So we believe in creating a flexible, asynchronous, and remote-friendly workplace, as long as the work is getting done well and on time, then we are satisfied.

What Markham Businesses Ask About Cybersecurity

Start with the controls that cover the most questions, which are MFA, endpoint protection, backups, and a written incident response plan. We review what you have, fix quick gaps, and help you answer truthfully with evidence.

Size matters less than access. Attackers often target smaller suppliers because they can lead to larger clients, and most attacks start with a stolen password or a convincing email rather than anything sophisticated.

It depends on users, devices, and the gaps we find. Ongoing security is part of managed IT at $80 to $150 CAD per user per month, and one-off projects are quoted in writing after the free assessment.

The most important fixes, such as MFA and removing extra admin rights, often take days. A full set of controls with documentation usually rolls out over a few weeks in phases, so daily work isn’t disrupted.

Usually, yes. Insurers tend to ask about the same controls, and a recent written assessment makes the application faster and more accurate. It can’t guarantee coverage or a lower premium, since that decision stays with the insurer.

No. We can work alongside your current provider or internal IT person. If you’d like to see what’s involved first, the free IT Readiness Assessment includes a security review.
