Cybersecurity services · Toronto & Canada-wide
Most attacks on a Canadian business start with one leaked password, one fake invoice or one laptop missing its updates. We watch the logins, the email and the devices around the clock, and when something happens the same engineers own it until it is fixed.
Sun IT Solutions is a Toronto and Markham based managed IT and security provider. Our security operations centre runs 24/7 for businesses across the GTA and Canada, with senior engineers who already know your environment.
The baseline we start from
Not sure where you stand? The twelve-question self-check below scores your setup in about two minutes.
How attacks actually land
Artificial intelligence has not invented new attacks. It has made the old ones faster and far more convincing, so the fake invoice reads well and the fake voice on the phone sounds right. These are the openings we close first.
The cheapest way into a business is a password that has already leaked, or a session token stolen by a phishing page. Nothing needs to be hacked and no alarm goes off.
Payment redirection still works because it is polite, well written and arrives when you are busy. The email looks like your supplier, because attackers study the real one first.
An unpatched machine is the easiest door in a small network, and a stretched team always patches last. Ransomware starts on one device and spreads to the file server.
A link shared for one client meeting stays live for years. Client records, payroll and contracts sit open to anyone who has the URL.
What we run for you
One line of defence is not enough. Each control below is set up, watched and reported on by our team, so a gap in one layer is covered by the next rather than becoming the way in.
A security operations centre watches your endpoints, email and logins every hour of every day, triages what it finds, and escalates to your Sun IT team to remediate. You are not relying on someone noticing.
Security Operations Centre (SOC)
Every laptop, desktop, server and phone is watched for malware and odd behaviour. If ransomware starts on one machine, that device is quarantined before it reaches your shared files.
EDR and managed antivirus
An AI-assisted email gateway scans links, attachments and sender history before mail reaches staff. Impersonation attempts and fake invoices are stopped at the gateway, not in someone's inbox.
Email security gateway
Multi-factor authentication on email, Microsoft 365 and every admin account, plus session and sign-in monitoring that blocks a stolen password before it becomes a breach.
MFA and identity threat detection
Malicious and newly registered websites are blocked at the network level, so a wrong click on a phone or laptop cannot reach the page that would have installed something.
Web and DNS filtering
Short, current modules and simulated phishing campaigns, with reporting that shows you who is clicking and who needs help. Staff who click get a quick lesson, not a telling off.
Phishing simulation
Tenant hardening, conditional access, third-party app review, retention and device policy — the settings most breaches walk straight through because nobody ever changed the default.
Microsoft 365 security hardening
Fifteen recommended controls working together, so when one layer misses something another intercepts it. Infected emails, compromised admin accounts and stolen laptops are each handled separately.
Defence in depth
PCI DSS for retail and payments, PHIPA for Ontario health records, PIPEDA for personal information, SOC 2 and insurer questionnaires. We prepare the evidence, not just the tools.
Compliance readiness
A named team, a written plan and tested backups. If an attack lands, we contain it, rebuild, and hand you a record of what happened for your insurer and your clients.
Incident response
Eyes on it, overnight
Most attacks land outside business hours because that is when nobody is looking. Our security operations run around the clock, and a person — not just an automated alert — decides what happens next.
What it costs
Protection is built into our managed plans rather than sold back to you as add-ons. Complete adds round-the-clock monitoring, endpoint detection and quarterly phishing training.
Essentials
$70/user /mo
Core support and protection for smaller teams that mostly need things to keep working.
Complete
$95/user /mo
Our most common plan: full monitoring, security operations and a named engineer.
If it happens today
Most of the damage in a ransomware or account takeover case happens before anyone reacts. Here is exactly what we do, in order, so nobody is making it up during the worst day of the year.
Under attack right now?
Call rather than email — the phone reaches an engineer immediately.
416-479-0505Ring 416-479-0505. If a device looks infected, unplug its network cable or switch off Wi-Fi, but leave it powered on so the evidence survives.
We reset credentials, revoke active sessions and tokens, enforce MFA, and block the sender and any malicious mailbox rules.
Sign-in logs, mailbox rules, file shares and device history tell us what was read, changed or taken, and whether anyone else is still inside.
Anything untrustworthy is rebuilt rather than cleaned up, and data comes back from a backup taken before the attack. We test that it opens.

Compliance and proof
Bigger clients, government tenders and cyber insurers now ask for evidence, not assurances. We run one control set and map it to the framework you are being asked about, so the work is done once and the paperwork follows.
Ask about compliancePIPEDA
Canada's federal privacy law for personal information held by private businesses.
Controls, retention and a breach record that stand up to an OPC enquiry.
PHIPA
Ontario health privacy law for clinics, dentists and health service providers.
Access controls, audit logs and staff training that health audits expect.
PCI DSS
The card networks' standard for anyone taking or storing card payments.
Network segmentation and evidence for the annual self-assessment.
SOC 2
Requested by enterprise clients and tenders when they review a supplier.
Control mapping and the written evidence an auditor will ask for.
ISO 27001
International information security management standard, for larger or exporting firms.
Gap analysis, policy set and a roadmap to certification readiness.
Cyber insurance
Insurers ask how you protect sign-ins, devices, backups and staff.

Cybersecurity FAQ
Still unsure? Ring 416-479-0505 and you will get an engineer's answer, not a sales script.
Managed cybersecurity means someone else runs your protection day to day: 24/7 monitoring, endpoint detection and response, email and phishing filtering, multi-factor authentication, managed patching, DNS filtering, security awareness training and a written incident response plan. With Sun IT Solutions the security team and the help desk are the same people, so when something is detected it is fixed, not just reported.
