Here’s a stat that may surprise you: 81% of all UK businesses that suffer from a cyber attack are small and medium-sized businesses (source).
A single mistake, like using a weak password or clicking a suspicious link, can put your business at risk. A cyber-attack doesn’t just mean a minor inconvenience, and it can bring your entire operation to a halt.
Imagine losing access to critical files, having your finances compromised, or having your business come to a standstill while you try to recover. The consequences are real, immediate, and can be devastating.
That’s why cybersecurity shouldn’t be an afterthought, especially for small businesses – as it’s often the independent retailers, builders, bookkeepers or other SMEs that are less prepared and less protected.
What are the most common cyber security mistakes small business owners make?
Many small businesses don’t fall victim to sophisticated hacks – instead, it’s the simple, everyday slip-ups that open the door to attackers. Things like reusing weak passwords, clicking on suspicious links, skipping vital software updates, or neglecting a backup plan for critical data.
The good news is that these mistakes are avoidable. By understanding where small businesses typically go wrong, you can take practical steps today to strengthen your defences and protect your business for years to come.
Here are some of the most common mistakes we see time and time again:
Weak passwords: is Password123 protection or invitation?
Let’s be honest, we’ve all done it, picked an easy password or used the same one for every single account. It’s tempting when you see that ‘Choose Password’ page to just go with the most memorable option, but it’s a choice you’ll regret down the line when a cyber attacker breaches not just one, but all your online accounts.
Reusing the same password is like hiding your house key under the doormat. Once someone finds it, they don’t just get into your front door – they can also wander into every room: your office, your bathroom, your garage. In the same way, if a hacker cracks one account where you’ve reused a password, they can often break into all your other accounts too.
In the workplace, one in three employees admit to never changing their work log-in (30%) or email (32%) passwords or only doing so when prompted (source). So, take this as your reminder to prompt your employees!
Phishing links: they’re getting harder to spot
Cyber criminals design emails to look authentic and urgent, often posing as colleagues or well-known businesses. They copy logos, mimic writing styles, and use convincing sender names to lower your guard. Urgent messages like “Your account will be closed” push you to act quickly, while links may appear trustworthy but redirect to fake sites that capture passwords, bank details, or other sensitive information.
Before clicking any link, we suggest you:
- Check the sender’s email address.
- Hover over the link to see the full URL.
- If anything feels off, trust your instincts and delete the message.
Software updates: a simple security must
Keeping your devices and data safe starts with regular software updates. Updates fix security holes that hackers look for, so skipping them can leave your information at risk. When you install updates right away, you help protect your accounts and keep your business running smoothly.
You can make things even easier by turning on automatic updates in your settings. That way, your files and business stay protected without you having to remember to do anything extra.
Ignoring cyber security: the biggest mistake of all
If you’re reading this thinking: “this won’t happen to me”, you’re wrong. A cyber-attack can happen to any business – particularly small to medium sized businesses.
It may feel like overkill to have protective measures in place, but once the attack has been carried out, recovery is nearly impossible. Meaning, if you’re not prepared, your assets are not safe.
