How poor cybersecurity can endanger your small business

Anna Stubbs • September 9, 2025

Digital systems and cloud technology have revolutionised the running of the average small business. But with software systems comes the ever present issue of cybersecurity.

And it’s not just the big league, like Boots and Marks & Spencers, that have to worry about getting hacked.

A recent BBC News article highlighted how one cracked password is all it took for a ransomware gang to destroy a 158-year-old transport company – putting 700 people out of work.

So, what can you do to increase your cybersecurity and keep your business, customer and finance information safe from hackers and malicious software?

Here are five ways to help protect your business

1. Use strong passwords and multi-factor authentication (MFA):

Make it mandatory for your team to use complex, unique passwords for all business accounts and devices. And make sure to enable multi-factor authentication (MFA) (sometimes called two-step authentication) so all software and system log-ins require a second form of verification, This makes it far more difficult for hackers to gain access to your systems.


2. Keep software and security patches updated:

Regularly update all your operating systems, software, apps and security patches, so you’re always using the most up-to-date versions. Cybercriminals will exploit any known vulnerabilities in out-of-date software, so patching these gaps is a critical step in preventing attacks.


3. Train your staff to recognise phishing and poor security:

Your employees are often the first line of defence. Provide regular training on how to spot suspicious emails, texts or calls. And make sure your team-members knows to avoid clicking on malicious links or downloading unverified attachments for example.


4. Secure and Regularly Back Up Your Data:

Make sure to back up your critical business data to a secure, separate location, like an encrypted cloud service or an external drive. With back-ups in place, you can be up and running quickly in the event of a ransomware attack or data breach.


5. Adopt the Cyber Essentials Scheme:

The Cyber Essentials initiative is a government-backed certification scheme that explains five ways to protect your business against the most common online threats. By completing the Cyber Essentials scheme, you demonstrate your commitment to cybersecurity and give the business increased protection against potentially harmful attacks.
