Security advice for small business owners tends to come in two flavors. Either it's so vague it's useless ("be careful online") or so technical it might as well be in another language.
Here's a third flavor: specific things you can actually do, none of which take more than five minutes, none of which require you to know how anything works under the hood. Do these on some kind of schedule and you're ahead of most of the businesses on your street.
1. Run a free scan (today, then quarterly)
Start here because it tells you where you actually stand instead of where you hope you stand. I built Cerberus for exactly this audience: go to cerberusscan.com, enter your website address, and in about a minute you get a plain-English report of what's exposed. No account gymnastics, no jargon wall.
Put a repeating reminder in your calendar for every three months. Sites drift. Certificates expire, software ages, things change. A quarterly minute keeps you current.
2. Look at your own website like a stranger
Once a month, open your site on your phone, in a private browsing window, like a customer would. Check three things: the padlock shows in the address bar, every page loads without warnings, and the contact form actually works when you submit it. You would be amazed how many businesses have a broken form or an expired certificate for weeks and find out from an annoyed customer. Be the first to know, not the last.
3. Update the software (or confirm someone does)
If your site runs on WordPress or similar, log in and look at the updates screen. If there's a number in a red circle, that's a count of open doors with fixes waiting. Apply them. If someone else maintains your site, send them a one-line message: "When were the site and plugins last updated?" A good maintainer answers instantly. A long silence is an answer too.
4. Fix your worst password
You know the one. The password you use in more than one place, or the one that's a pet's name plus a year. This month, change just your website admin password to something long and unique, and turn on two-factor authentication if it's offered. One password, five minutes. The admin login is the single most valuable door your site has, so this is where a strong lock pays best.
5. Check your backups exist
Don't get fancy. Just answer one question: if the site vanished tonight, could someone restore it, and from when? Ask your host or your web person. If the answer is "yesterday's copy, automatically," you're fine. If the answer involves shrugging, that's the most important five minutes on this list.
The habit is the point
None of these make you invincible, and I won't pretend otherwise. What they do is take you out of the "easy" pile, which is where nearly all small business breaches come from. Automated attacks don't defeat defenses. They walk through the absence of them.
Five minutes here and there is genuinely enough to change which pile you're in. Cheddar spends longer than that deciding where to lie down.
Want the once-over done for you instead? Run the free scan at cerberusscan.com, and if anything in the report needs handling, book 30 minutes at ctfdesigns.com/book and I'll take it from there.
