Cyber security can feel like one of those things that only big businesses need to worry about.

But the reality is that every business relies on technology in some way. Whether it’s email, Microsoft 365, online banking, customer information, cloud applications or simply the laptops your team uses every day, there’s plenty worth protecting.

And you don’t need to be doing anything obviously “wrong” to leave gaps in your security.

Here are five common cyber security mistakes businesses can make without even realising.

1. Relying on passwords alone

Passwords are still essential, but they shouldn’t be your only line of defence.

If a password is weak, reused across different accounts or compromised elsewhere, it could potentially give someone access to important business systems.

That’s where multi-factor authentication (MFA) comes in. It adds another layer of verification when somebody signs into an account, making a stolen password alone less useful to an attacker.

It’s a relatively simple change that can make a big difference to your overall security.

2. Putting off software updates

We’ve all done it.

You’re halfway through something, an update notification pops up and you click “Remind me later.”

The problem is that software updates aren’t just about getting new features. They can also include important security fixes for known vulnerabilities.

Keeping operating systems, applications, browsers and devices up to date should therefore be part of your everyday approach to cyber security, rather than something that gets left until there’s a problem.

3. Forgetting that your people are part of your cyber security

You can invest in security technology, but your employees still play an important role in keeping your business safe.

Phishing emails and other social engineering attempts are designed to look convincing. They may appear to come from a colleague, supplier or organisation your team recognises and encourage someone to click a link, open a file or share information.

Regular cyber awareness training can help your employees recognise the warning signs and, importantly, know what to do when something doesn’t feel right.

The aim isn’t to make your team suspicious of every email they receive. It’s to give them the confidence to stop, check and ask.

4. Assuming your business is too small to worry about cyber security

It’s easy to think:

“Why would anyone target us?”

But cyber security isn’t only about someone deliberately choosing a particular company. Many threats are widespread and opportunistic, meaning businesses of all sizes need sensible protection in place.

Rather than asking whether your business is big enough to be targeted, a better question is:

If something did happen tomorrow, how prepared would we be?

Do you know how important data is protected? Who has access to your systems? What would happen if a device was compromised? And who would your team contact if something suspicious happened?

Having those conversations before there’s an incident can make all the difference.

5. Treating cyber security as a one-off job

Perhaps the biggest mistake is thinking cyber security is something you can simply tick off the list.

Technology changes. Your team changes. New devices are added, employees join and leave, software is introduced and new threats emerge.

That means your cyber security needs to evolve alongside your business.

Regularly reviewing your systems, access controls, devices, software, backups and security measures can help you identify gaps before they become bigger problems.

Cyber security doesn't need to be intimidating

You don’t need to become a cyber security expert overnight.

For most SMEs, it’s about getting the fundamentals right, understanding where your potential vulnerabilities are and putting sensible protection in place.
