Cyber security top tips for small businesses

Cyber security is no longer just an issue for large organisations. Small businesses are increasingly targeted by cyber criminals, and many lack the time or resources to recover if something goes wrong. In a connected world, protecting your data, systems and customers is a core part of running a resilient, investable business.

According to the Cyber Security Breaches Survey 2025, UK businesses experienced an estimated 8.85 million cyber crimes in the last 12 months. Nearly half of all businesses reported at least one cyber security breach, with small companies firmly in the firing line.

Why cyber security matters for your business

Everything in your business is connected. Customer data, payment systems, supplier relationships and reputation all rely on digital tools. If trust is broken through a cyber incident, it can be extremely difficult to rebuild.

There is also a legal and ethical responsibility to protect data properly. Beyond fines, a breach can damage customer confidence, disrupt operations and put off future investors or partners.

Importantly, the biggest cyber security risk is often people. A single careless click, weak password or convincing scam email can undo even the best technical systems.

Common cyber threats facing small businesses

Cyber attacks are usually an attempt to damage, disrupt or gain unauthorised access to your systems. The most common threats include:

• Phishing: Scam emails, texts or phone calls designed to look legitimate and trick staff into clicking links or sharing information. This is the most common attack affecting SMEs.
• Malware: Malicious software such as viruses, trojans and ransomware. Ransomware can lock you out of your systems or data until a payment is demanded. Official advice is not to pay, as this often leads to further attacks.
• Insider threats: Disgruntled or careless staff who accidentally or deliberately compromise security.
• AI-enabled scams: Generative AI is making phishing emails, fake voices and videos more convincing. Impersonation of suppliers or senior staff is a growing risk.

No sector is immune. Cyber criminals are opportunistic and often see small businesses as easier targets.

Practical cyber security tips you can act on now

1. Train your people
   Staff awareness is one of the most effective defences. Short training on spotting phishing emails, using strong passwords and handling data safely can dramatically reduce risk. Free 30-minute training resources are available via the National Cyber Security Centre.
2. Use strong passwords and two-step verification
   Encourage unique, complex passwords and consider using a password manager. Enable two-step verification wherever possible to block many common attacks.
3. Keep software up to date
   Outdated software is a major weakness. Install updates and patches promptly, as many attacks exploit known vulnerabilities that already have fixes available.
4. Back up your data regularly
   Regular offline or cloud backups mean you can recover quickly if ransomware hits, without paying a ransom. Make backups automatic where possible.
5. Think about your supply chain
   An attack on a supplier can affect your business too. Ask key suppliers how they manage cyber security and data protection, especially if they access your systems.
6. Monitor and prepare for incidents
   Make sure you know how to spot unusual activity and what to do if something goes wrong. Even a simple incident response plan can save valuable time during an attack.
