Most small and medium businesses know they should take cybersecurity seriously. After more than 25 years supporting SMEs, we’ve seen the same cybersecurity mistakes appear repeatedly. It’s not that owners don’t care. Usually, these things just feel like a job for “later.” Then later becomes too late.
Recent figures paint a clear picture: more than a third of UK SMEs faced a cyber incident in the past year, while nearly half give no cybersecurity staff training at all. Two thirds haven’t added any new security measures in the last twelve months. These aren’t rare, unlucky businesses; this is the normal picture across the UK right now.
Here are the mistakes that come up again and again, and why they matter more than they seem to at first.
Believing You’re Too Small to Be a Target
This is probably the biggest mistake of all. Many owners assume hackers only go after large companies with deep pockets. It feels logical – why would a criminal bother with a small business?
The truth is the opposite. Criminals often prefer small businesses as they tend to have weaker defences, fewer IT staff and spend less time checking for problems. Most attacks are automated anyway. A scam email doesn’t know or care how big your company is, it just needs one person to click.
Nearly three in ten SMEs say a single attack could put them out of business entirely. That’s not a small risk to shrug off.
Weak or Reused Passwords
Passwords remain one of the easiest doors for criminals to walk through. Simple passwords can be guessed quickly, but reused passwords are worse. If one account gets breached somewhere else online, and your team uses that same password at work, criminals already have a way in.
This mistake is easy to fix, yet easy to ignore. A password manager, plus multi-factor authentication, closes most of this gap without much effort from staff.
Skipping Staff Training
Technology can block a lot of threats, but people make the final call on whether to click a link or ignore it. Without training, staff simply don’t know what a scam email looks like. They don’t know why a strange request for a bank transfer should raise a flag.
Almost half of UK SMEs give their staff no training on this at all – that’s a huge gap! That’s why many attacks rely entirely on tricking a person, rather than breaking through any piece of technology.
Training doesn’t need to be long or dull. Short, regular reminders work far better than one boring session a year that everyone forgets within a week.
Ignoring Software Updates
Software updates often feel like an annoying pop-up you click away without thinking. However, many updates exist purely to close security holes that criminals already know how to use. Delaying an update, even by a few weeks, leaves a door open that didn’t need to stay open.
Businesses without a proper update routine tend to run outdated systems for months. Often, they don’t even realise it. A clear schedule for updates removes the guesswork completely.
Backups That Have Never Been Tested
Many businesses have backups running somewhere. Far fewer have actually tried restoring from them. A backup that quietly fails is almost worse than having no backup at all because you only find out it doesn’t work at the exact moment you need it most.
Ransomware attacks make this mistake especially costly. If your files get locked and your backup doesn’t restore properly, you’re left with very few good options.
Treating Cybersecurity as a One-Off Job
Some businesses set up security once, tick the box, and move on. But threats never sit still. New scams appear all the time and new software vulnerabilities are discovered. A setup that felt solid two years ago may have gaps today that simply didn’t exist back then.
Two thirds of SMEs haven’t added any new security measures in the past year. That’s a long stretch of time for threats to move forward, while defences stay exactly where they were.
No Plan for When Something Goes Wrong
Even well-protected businesses can still get hit. What often separates a manageable incident from a disaster is having a plan ready beforehand:
Who gets called first? What gets switched off? How does the business keep running while it all gets sorted?
Without a plan, the first hour after an attack usually gets spent in confusion, not action. That confusion costs time and often, it costs money too.
Assuming One Tool Covers Everything
A lot of businesses buy one piece of security software, install it, and consider the job done. Yet it’s important to understand that no single tool covers every angle. Antivirus software won’t stop a scam email that tricks someone into handing over a password willingly, and a firewall won’t catch a fake invoice sitting in an inbox. Real protection comes from a few different layers working together, not one product doing all the heavy lifting alone.
Putting Off the Fix Because It Feels Like a Big Job
A lot of business owners know, deep down, that something needs sorting. Maybe it’s the password policy nobody follows, or maybe it’s the backup nobody has checked. These things get pushed down the list, because they feel like a big project with no clear starting point.
In reality, most of these fixes take far less time than expected. Turning on multi-factor authentication across a small team can take an afternoon. Running one short training session can take less than an hour. The hardest part is usually just deciding to start, not the work itself once it begins.
How Cheeky Munkey can help avoid these mistakes
None of this needs a total overhaul overnight. Most businesses make real progress just by tackling the biggest gaps first. Turn on multi-factor authentication. Run one short training session. Test a backup properly, just once, to see if it actually works the way everyone assumes it does.
Cheeky Munkey helps SMEs across St Albans and the wider UK spot these gaps and close them, without piling on extra complexity nobody asked for. If you’re not sure where your business stands right now, get in touch with our team for a straightforward, no-pressure review.
