Managed IT Services Newmarket: IT Support & Cybersecurity

We look after Newmarket businesses from our office in Vaughan, with most work done remotely and visits booked when equipment needs hands on it. One team runs the day-to-day support and the security, so there is one party accountable when something breaks.

A managed agreement covers the helpdesk, monitoring and patching, Microsoft 365, restore-tested backups and security on each managed device, scoped per month to your users and devices. Support is 24/7, and serious incidents go to the same 24/7 line, (289) 582-9930.

Along Davis Drive and the Viva rapidway, and around Southlake Regional Health Centre, the mix is clinics, specialists and professional offices. Patient records fall under Ontario's Personal Health Information Protection Act, so access controls, device encryption and tested backups are the baseline.

Clinics also cannot have patching interrupt a day of appointments. We schedule maintenance outside clinic hours and keep the practice-management system on a tested recovery plan. See healthcare IT and dental IT.

The Regional Municipality of York headquarters is on Yonge Street in Newmarket, and many local consultants, engineers and contractors work for public bodies. They get asked about MFA, patching and backup testing in procurement, in writing.

We set up the controls and keep the evidence: dated restore tests, patch reports, an access review and a written incident plan. Public-sector buyers increasingly expect the Cyber Centre's baseline controls or something close to them.

East of Yonge, the business parks off Harry Walker Parkway and the light-industrial units near Highway 404 hold distributors, manufacturers and trades companies with a warehouse or shop floor behind the office.

There the network has to cover a bigger space and keep scanners and production machines apart from accounting. We segment floor devices, extend Wi-Fi to where the work happens, and monitor the ERP or inventory server so a fault is caught before the next shift.

On historic Main Street and in the plazas along Mulock Drive, retailers and small offices rarely need a server. They need a reliable point-of-sale connection, a backup internet line, and someone who has written down how the network is set up.

For those businesses useful IT support is simple: one number to call, devices patched and protected without anyone remembering to, and payment terminals on their own network away from guest Wi-Fi.

Invoice fraud from a spoofed domain is the most common attack we see against small York Region firms. In our August 2026 study of 481 GTA business domains, only 20.6% enforced DMARC, and the earlier July 2026 pilot (118 GTA domains) found only 40% fully protected against spoofing.

Our first checks for every new client: MFA on every Microsoft 365 account, SPF, DKIM and DMARC on the domain, and a backup restore that is tested and dated. Try the email spoof check on your own domain. Not sure what to fix first? The IT risk self-check walks you through your setup in a few minutes, on screen or on paper.

Most Newmarket firms that call us already have a provider. The switch is mostly about getting control of what the old provider holds: admin logins, the domain registrar, the firewall and the backup console.

We move those to accounts you own first and remove the old provider's access last. Our switching guide sets out each step, and our Microsoft 365 clean-up for a GTA fire protection company shows the kind of tidy-up that usually follows.

The agreement is written per month and sized to your users, devices and sites. A ten-person accounting office on Main Street and a sixty-person distributor near Highway 404 get the same list of services, at very different scale. Before you sign, the scope document should name each of these, so nothing is assumed:

• Helpdesk: staff email or call us directly, and every request is logged with a ticket number you can follow.
• Monitoring and patching for servers, PCs and network equipment, with a monthly report of what was patched and what was deferred and why.
• Microsoft 365 administration: new starters, leavers, licences, shared mailboxes, Teams and SharePoint permissions.
• Backups that are restored on a schedule, with the date of the last successful test written down.
• Security on each managed device: endpoint protection, disk encryption and MFA enforced on every account.
• Network and firewall management, including firmware updates and the change log.
• A planning review, usually quarterly, covering hardware ages, renewals and what to budget for next year.

Most Newmarket offices we see were set up by whoever installed the internet. The router the provider supplied is doing the job of a firewall, the guest Wi-Fi shares a network with the reception PC, and nobody has the admin password written down.

The fix is not expensive and it is not exotic. A business firewall that is patched and logged. Separate networks for staff computers, payment terminals, cameras and guests. Remote access through a VPN or Microsoft's own tools with MFA, never an open remote-desktop port. For clinics, exam-room PCs locked to the practice software and nothing else.

The Canadian Centre for Cyber Security publishes a short list of baseline controls for small and medium organizations. We use it as the checklist because it is free, Canadian, and the same list a public-sector buyer or insurer is likely to hold you to.

That includes a managed email service: Newmarket offices get Microsoft 365 mail, filtering and SPF, DKIM and DMARC looked after as one service.

Hourly work suits a firm with a short, known list of jobs: move the office, replace a server, set up a new site. You pay for the work, and nobody watches your systems between visits.

A managed agreement suits a firm where IT problems interrupt the working day often enough that someone on staff has become the unofficial IT person. The agreement moves that job off their desk and puts patching, backups and account changes on a schedule rather than on memory.

Some firms do both: an internal person handles the day-to-day and we cover security, backups and the projects they do not have time for. That arrangement is co-managed IT, and it works well for Newmarket firms that grew past twenty staff with a capable office manager still running the computers.

A good provider answers these in writing without hesitation. A vague answer to any of them is useful information.

• Who owns the admin accounts, the domain and the backup console? It should be you, with the provider holding delegated access.
• When was a backup last restored as a test, and can we see the record?
• What is the written reply commitment, and what happens after hours?
• What is in the monthly scope, and what is billed separately?
• How do we leave? Ask for the exit process before you sign, including how long handover takes.
• Which security controls will be on by default for every user?

An assessment goes faster, and costs you less of your own time, if a few things are gathered first. Most offices have all of it, just in different drawers.

Make a list of staff and the devices each person uses, including phones that get company email. Find the login for the domain registrar (where you bought the web address) and the Microsoft 365 or Google admin account. Note who supplies the internet, phones, printers and any line-of-business software, with account numbers. Write down anything that has broken more than twice this year.

If a previous provider holds some of those logins, say so at the start. Recovering access is routine, and it is better done calmly than in the middle of a problem. Our switching guide covers how that handover is usually arranged.

Most Newmarket offices we take on already use Microsoft 365, set up years ago by whoever was available. The tidy-up is predictable: give every shared mailbox an owner, remove licences from people who left, switch on MFA and block legacy sign-in, and check what has been shared outside the firm from OneDrive and SharePoint. Microsoft's external sharing settings are usually the surprise. None of it is glamorous, and all of it closes the gaps that attackers actually use.
