Cyber security doesn’t have to be complex, expensive, or time-consuming. For most small business owners, the biggest risks come from small things being overlooked; outdated software, unused logins, or weak access controls.

That’s where cyber hygiene comes in.

Cyber hygiene is the practice of maintaining good digital habits to keep your business safe online. Just like physical hygiene, it’s not about doing one big clean once a year - it’s about small, regular actions that reduce risk over time.

In 2026, one of the most effective things you can do for your business is commit to a weekly 5-minute cyber hygiene check. Here’s how.

The Weekly 5-Minute Cyber Hygiene Checklist

1. Check for software updates

Software updates aren’t just about new features, they often include critical security patches. Running outdated software leaves your systems vulnerable to known threats.

Each week, take a moment to check that your operating system, apps, plugins and tools are up to date, especially anything tied to payments, customer data or communications.

Why it matters: Updates close security gaps that hackers actively exploit.

2. Log out of unused apps

If you’ve logged into tools you no longer use, especially on shared or public devices - those sessions can become an easy entry point for cyber attacks.

Log out of apps you haven’t used recently and remove access entirely where possible.

Why it matters: Fewer active sessions mean fewer opportunities for unauthorised access.

3. Review who has access to your accounts and tools

Over time, it’s easy to forget who has access to what; former staff, contractors, collaborators or agencies.

Do a quick scan of user permissions across key platforms like email, cloud storage, accounting software and social media.

Why it matters: Limiting access to only the people who need it reduces risk and protects sensitive information.

4. Back up critical files

Backups are your safety net. If something goes wrong; a cyber attack, accidental deletion, or hardware failure, backups can be the difference between a minor inconvenience and a major disruption.

Make sure your most important files are backed up regularly, ideally using an automatic cloud backup.

Why it matters: Backups protect your business continuity and reduce downtime.

5. Ensure two-factor authentication (2FA) is set up

Two-factor authentication adds an extra layer of security by requiring a second step to log in, usually a code sent to your phone or an authentication app.

Check that 2FA is enabled on all critical systems, including email, banking, cloud storage and social media.

Why it matters: Even if a password is compromised, 2FA can stop unauthorised access.

6. Check mailbox spam filters

Spam filters can sometimes block legitimate emails, or let harmful ones through.

Take a moment to review your spam and junk folders, mark legitimate emails as safe, and stay alert for suspicious messages.

Why it matters: Phishing emails remain one of the most common ways businesses are targeted.

Small Habits, Big Protection

Cyber security isn’t about being perfect, it’s about being consistent.

Spending just five minutes a week on cyber hygiene can significantly reduce your risk, protect your data, and give you greater peace of mind as a business owner.

In 2026, working smarter includes protecting what you’ve built. Make cyber hygiene part of your regular routine, your future self (and your business) will thank you.
