Cybersecurity Tips for Small Businesses (From People Who Used to Cut Corners)

Start with the boring stuff. It stops most attacks.

Most small teams work that way. Ship first, lock it down later. Later rarely comes.

We've since learned that small businesses aren't too small to target. They're just easier. So here are the tips we wish someone had drilled into us, written for owners, not IT departments.

• Turn on two-factor login everywhere. Email, banking, payroll, your app store and cloud accounts. If you do one thing today, do this.
• Use a password manager. Reused passwords are the open window. A manager makes every login unique without you remembering any of them.
• Update everything. Phones, laptops, routers, plugins. Most break-ins use holes that already have a fix.
• Back up, then test the backup. A backup you've never restored is a guess, not a plan.
• Remove old access fast. When someone leaves, their accounts leave the same day.

Watch the human side

Most attacks today start with a message, not a hack.

• A fake invoice from a "supplier" with new bank details.
• A text that looks like it's from your bank, your courier or the tax office.
• A voice call that sounds like your boss. AI voice cloning makes this easier than ever.

One rule fixes a lot: any request to move money or change payment details gets confirmed by phone, using a number you already have. Not the one in the message.

If you're building an app or adding AI

This is where we see small companies, and our younger selves, slip.

• Don't hard-code secrets. API keys in an app's code can be pulled out. Keep them on a server.
• Collect less data. Data you never store can't leak. Ask what you truly need.
• Treat AI like a new employee. Limit what it can see and do. Don't paste private client data into a free chatbot account.
• Test the unhappy paths. What happens when someone types something weird, or uploads the wrong file? Attackers start there.
• Know your rules. In Canada, PIPEDA applies to personal data, and Québec's Law 25 adds stricter duties, including reporting certain breaches.

The honest trade-off

Security costs time, and time feels expensive when you're small. We get it. We made that trade for years.

But we've also seen the other side of the ledger: lost customer trust, app store reviews you can't erase, and days spent cleaning up instead of building. A few hours of prevention is the cheapest insurance you'll ever buy.

How Apprika Labs can help

We're a Canadian AI, app and software studio. Our background is consumer apps; we're newer to business clients, with Skolr, an education platform, as our first B2B contract. Schools hold sensitive data, so security there isn't optional, and it has sharpened how we work everywhere.

We bake security into every build:

• Apps and software with sensible defaults from day one.
• Private AI that keeps your data where it belongs.
• Forward deployed engineers who can review how your team actually works and close the gaps.
• AI Training, including how to spot AI-powered scams.

We'll also tell you when you need a dedicated security firm instead of us.

Questions people ask

What is the most important cybersecurity tip for a small business?

Turn on two-factor authentication for every key account. It blocks a large share of account takeovers.

Are small businesses really targeted?

Yes. Attackers often prefer small firms because their defences are weaker.

Is it safe to use AI tools with company data?

Use business plans with clear data terms, limit what you share, and never paste sensitive client data into free consumer accounts.

What does Québec's Law 25 require after a data breach?

Organizations must report breaches that pose a risk of serious injury to the regulator and to affected people, and keep a register of incidents.
