Best antivirus for Canadian small businesses

A Smithville shop does not need a security-operations floor. It needs an agent that is actually on, an honest CAD or USD sticker, and a clear line between the Windows toggle and a paid console. US “best antivirus 2026” lists skip the part that changes the bill: GST/HST on Norton, Microsoft, or a USD Falcon seat, and the fact that built-in Defender may already be enough.

This comparison is the set shops actually open: Bitdefender GravityZone (en-ca calculator, taxes not included), Norton Small Business (C$ cards), Microsoft Defender for Business (built-in Windows vs a CAD seat), CrowdStrike Falcon Go (public USD SMB SKU), with SentinelOne only where the official list is public, and ESET as the Canadian sales-office option. Antivirus and endpoint prices checked against public vendor pages, 6 September 2026. This is not a lab bake-off and not a threat forecast.

Who this page is for

• A Canadian SMB quoted Norton or Bitdefender who already has Windows Security on.
• A shop mixing a household Norton 360 login with five staff PCs — those are different SKUs.
• Anyone told Falcon Go prints CAD, or that SentinelOne’s web list is the invoice.
• Not a hands-on lab. Not a SOC-as-a-service RFP. Not invented detection scores.

Snapshot (public pages, 6 September 2026)

Bitdefender GravityZone — endpoint calculator, no static CAD card

Official bitdefender.com/en-ca GravityZone Small Business Security is the SMB endpoint SKU: 1 to 100 devices (laptops, desktops, file servers), online purchase only, prices based on endpoint count (up to 30% can be servers). Auto-renew unless you cancel. The official en-ca page is a device calculator. This retrieve printed “Taxes not included” / “VAT not included” and no static CAD list. Confirm the live widget. Do not paste a blog’s $324.99/10-device figure as Bitdefender’s Canadian card. Source: https://www.bitdefender.com/en-ca/business/products/gravityzone-small-business-security.

GravityZone is the cloud console path. A consumer Total Security box is not a shop dashboard and not this SKU. Buy GravityZone when the shop wants one console for Windows / Mac endpoints and will confirm the live total. Do not treat a household Bitdefender download as that console. The café hop is still VPN for Canadian small businesses.

Norton Small Business — C$ cards, consumer-grade console honesty

Official ca.norton.com/products/small-business (6 September 2026): Norton Small Business C$124.99 first year (6 devices), C$174.99 first year (10), C$274.99 first year (20). Cards say plus applicable sales tax. Confirm the live widget — first-year intros move. Official trial line on the same page: payment method required; when the trial ends, paid subscription starts at C$79.99/first year and automatically renews at C$124.99/year unless cancelled. Price is subject to change. Source: https://ca.norton.com/products/small-business.

Norton Small Business Premium on the same compare table: C$269.99 first year (10 devices) and C$349.99 first year (20), plus applicable sales tax. Premium adds 500 GB cloud backup, Secure VPN, and Driver Updater. Standard includes Device Security, 250 GB backup, Private Browser, Software Updater, Utilities Ultimate, and Password Manager.

Official FAQ: Norton Small Business provides essential endpoint protection for small businesses that do not require a business dashboard and remote management. Norton 360 is the household SKU (5–20 devices). This is not GravityZone and not Defender for Business. The included Password Manager is not a shop vault. Premium’s Secure VPN is not the dedicated-IP path on VPN for Canadian small businesses. Confirm sales tax at checkout.

Microsoft Defender — built-in Windows vs a CAD Business seat

Official Microsoft Defender for Business FAQ: Microsoft Defender Antivirus is next-generation protection built into Windows. It helps protect those devices from viruses, malware, and potentially unwanted applications. That is the Windows Security toggle — not a SaaS seat. Official FAQ: Defender for Business includes Defender Antivirus capabilities and extends them with cyberthreat and vulnerability management, attack surface reduction, endpoint detection and response, and automated investigation and response. Built-in Windows antivirus is not that console. Source: https://www.microsoft.com/en-ca/security/business/endpoint-security/microsoft-defender-business.

Official microsoft.com/en-ca Defender for Business card: CAD $4.10/user/month paid yearly, plus applicable tax. Price does not include tax. Up to 300 users and up to five devices per user, no minimum device count. 30-day trial listed. Windows, macOS, iOS, and Android. Defender for Business is included in Microsoft 365 Business Premium (CAD $29.80/user/month paid yearly, plus tax) and Business Premium (no Teams) at CAD $25.50. Confirm the live CAD widget. Source: https://www.microsoft.com/en-ca/security/small-medium-business/pricing.

Tax is determined by the business address, or the shipping address if it is different. North/Central/South America section: in Canada, various tax rates apply depending on the product and your location. Canada is listed as a Limited Risk Distributor market. Tax-exempt path: Certificate of Exemption (or equivalent) via a service request. Not tax advice. Source: https://learn.microsoft.com/en-us/microsoft-365/commerce/billing-and-payments/tax-information.

Already on Microsoft 365 Business Premium: Defender for Business is on that card. Do not buy Norton or Falcon Go for the same Windows seat unless someone can name the extra console. Seat math: Google Workspace vs Microsoft 365 in Canada. Built-in antivirus on a single PC is still $0.

CrowdStrike Falcon Go — public USD SMB SKU

Official crowdstrike.com Falcon Go: US$7.99 per device billed monthly, or US$59.99 per device billed annually. Official note: all prices in US dollars. Purchases limited to a maximum of 100 devices. Same official page, annual: Falcon Pro US$99.99/device; Falcon Enterprise US$184.99/device. Monthly: Pro US$14.99; Enterprise US$19.99. Go is next-gen antivirus + device control + mobile. EDR sits on Enterprise on that compare table. Official cards print USD. No published CA$ Falcon SKU on that retrieve. Confirm tax at checkout. Do not convert US$59.99 into loonies. Source: https://www.crowdstrike.com/en-us/pricing/falcon-go/.

Falcon Go is the self-serve SMB row: next-gen antivirus, USB device control, and mobile, capped at 100 devices. Official compare table: EDR is on Falcon Enterprise, not on Go. This page does not convert US$59.99 into loonies and does not repeat vendor lab scores as a NorthOffice test.

SentinelOne — public USD list, partner quote controls

Official sentinelone.com/platform-packages: Singularity Complete US$179.99/year per endpoint; Commercial US$229.99/year per endpoint; Enterprise is contact-sales. Official note: prices in US dollars and may not include taxes; displayed for 5–100 workstations. Official same page: all purchases go through an authorized third-party partner. Displayed prices do not reflect final pricing. Partner quote controls if it conflicts. Source: https://www.sentinelone.com/platform-packages/.

Include SentinelOne only if you will take a partner quote. The web list is a starting number for 5–100 workstations, not a Canadian CAD SKU. A five-person shop should price Defender for Business or GravityZone before a US$179.99/endpoint card.

ESET — Canadian sales office, official calculator

Official eset.com/ca/about/contact: ESET Canada Sales & Marketing Office, 125 Commerce Valley Dr West, Suite 601, Thornhill, ON L3T 7W4. Small-business licences up to 100 devices are listed as a sales path on that page. Source: https://www.eset.com/ca/about/contact/.

Official eset.com/ca Small Business Security: 5–25 devices (PC, macOS, smartphones, tablets, and Windows Servers). First-term prices; if a savings amount is shown it is first term vs official list. Confirm the live widget — this retrieve did not print a static CAD sticker. ESET PROTECT is the IT-admin / growing-business console path on the same CA site (5 to unlimited devices). That is a different SKU from the HOME set-and-protect Small Business Security pack. Official CA store is a device calculator. Do not paste a reseller CAD figure as ESET’s card. Confirm currency and tax at checkout. Source: https://www.eset.com/ca/home/small-business-security/.

ESET is here because official CA pages name a Thornhill sales office and a small-business licence path — not because this page invented a CAD sticker. Confirm the widget. The included VPN on Small Business Security is still not the shop tunnel comparison on VPN for Canadian small businesses.

When Microsoft Defender is enough

• One Windows laptop, Windows Update on, no file server: built-in Defender Antivirus. No SaaS line. The box itself is laptops for Canadian small businesses.
• Five staff on mixed Windows / Mac / phones and you already pay Microsoft 365 Business Premium: stay on Defender for Business. It is on that CAD card.
• Same mix, no Premium yet: standalone Defender for Business at CAD $4.10/user/month yearly plus tax — confirm the widget — before Norton or Falcon Go.
• Household phones plus a till PC and no remote dashboard: Norton Small Business C$ cards, if you accept first-year vs renewal.
• One cloud console for endpoints, including a file server share: Bitdefender GravityZone or ESET PROTECT — confirm the calculator, not a blog CAD figure.
• Café Wi-Fi is still VPN for Canadian small businesses. Shared passwords are still password managers for Canadian small businesses.

A practical pick

1. Solo Windows PC: leave built-in Defender on. Buy nothing for the same scan.
2. Already on Microsoft 365 Business Premium: stay on Defender for Business. Do not stack Norton on that seat.
3. Need a paid console and you want a printed CAD seat: Defender for Business at CAD $4.10/user/month yearly, plus tax.
4. Mixed devices, no dashboard, printed C$: Norton Small Business. Price the renewal line, not only first year.
5. Endpoint console and you will confirm a calculator: Bitdefender GravityZone or ESET (Thornhill sales office). No invented CAD.
6. You accept USD per device and a 100-device cap: CrowdStrike Falcon Go. SentinelOne only with a partner quote. Hotel Wi-Fi is still the VPN page; the vault is still the password-manager page.
