Small Business Cybersecurity Checklist for BC Businesses
Small business cybersecurity is the set of practical controls that protect a company’s data, email and systems from attack — without the budget or staff of a large enterprise. Most successful attacks on small businesses do not involve sophisticated techniques. They involve a password reused across sites, an email nobody questioned, or a backup that turned out not to work.
This checklist covers what genuinely reduces risk for a business of five to fifty staff in British Columbia, in rough order of importance.
1. Turn on multi-factor authentication everywhere
If you do one thing, do this. MFA blocks the overwhelming majority of account takeover attempts, because a stolen password alone stops being enough.
Enforce it on email first, then remote access, then any system holding client data. “Available but optional” does not count — staff will skip it. Use an authenticator app rather than SMS where you can.
2. Get email security right
Email remains the entry point for most incidents. Two things matter:
Filtering that catches phishing and malicious attachments before they reach anyone. The protection built into basic email plans is weaker than most owners assume.
Authentication records — SPF, DKIM and DMARC — which stop criminals sending mail that appears to come from your domain. Without these, someone can impersonate your business to your own clients. Proper email security covers both.
3. Replace antivirus with endpoint detection
Traditional antivirus recognises known threats. Modern attacks are built specifically to avoid that. Endpoint detection and response watches for suspicious behaviour rather than known signatures, and can isolate a compromised device before it spreads.
Critically, endpoint protection only works if someone reviews what it reports. An alert nobody reads is not protection.
4. Test your backups by restoring them
Ask a simple question: when did someone last restore a file from backup to check it worked?
For most small businesses the honest answer is never. Backups fail silently — a service disconnects, a drive fills, a folder gets excluded — and nobody notices until the day it matters.
Your backups should also be isolated from the network they protect, because ransomware deliberately seeks out and encrypts reachable backups. Cloud backup with tested restores is the practical answer for most businesses this size.
5. Keep software updated
Most breaches exploit vulnerabilities that were patched months earlier. Enable automatic updates for operating systems and browsers, and make sure someone is responsible for the things that do not update themselves — firewalls, network equipment, line-of-business software.
Equipment past end-of-life stops receiving security updates entirely. If a device no longer receives patches, it is a liability regardless of whether it still works.
6. Remove access people no longer need
Two habits cause most of this problem: accounts for former staff that are never disabled, and everyone having access to everything because it was simpler at the time.
Keep a list of who has access to what. Disable accounts the day someone leaves, not the month after. Give people access to what their role requires, rather than to the entire file store.
7. Train your staff, briefly and regularly
Security training does not need to be lengthy. Short, regular sessions work better than an annual presentation nobody remembers.
Cover the things that actually happen: how to recognise a phishing email, why a supplier suddenly changing bank details is always worth a phone call, and who to tell when something looks wrong. That last point matters most — staff who fear blame report incidents late, and late reporting is what turns a contained problem into a serious one.
8. Secure your network properly
A business-grade firewall, properly configured and kept updated, does real work. So does separating guest Wi-Fi from the network your business systems run on — visitors should never be on the same network as your servers and workstations.
If staff connect remotely, that access needs to be secured and monitored. Network security is where a lot of small businesses have gaps they cannot see.
9. Write down what you would do
An incident response plan for a small business can be one page: who to call, in what order, who decides whether to pay, who contacts clients, where the backups are and who can restore them.
The value is not the document. It is having made the decisions before you are making them at 2am under pressure.
10. Know what data you hold
If you hold personal information about BC residents, you have obligations under BC PIPA and PIPEDA — including notifying affected people about breaches that pose real risk of significant harm.
You cannot protect data you have not identified. Knowing what you hold, where it lives and who can reach it is the foundation everything else sits on. For clinics and healthcare practices specifically, our BC PIPA IT security checklist goes into more detail.
Where to start
If this list feels like a lot, start with the first four: MFA, email security, endpoint detection and tested backups. Those four address the majority of realistic risk for a business this size, and the rest can follow.
