5 Things an SME Can Implement to Improve Their Cybersecurity

As outlined in last week's blog, cybersecurity is no longer a “nice to have” for SMEs; it’s a business survival requirement. The potential risks of a cyberattack are catastrophic for an SME. With phishing, ransomware, and data breaches on the rise, and with SMEs increasingly targeted due to weaker security controls, taking proactive steps can drastically reduce your risk exposure.

Here are five essential, high‑impact actions every SME should prioritise:

1. Train Your Staff

Human error remains the number‑one cause of cyber incidents. Staff are your first line of defence, but only if they’re properly trained.

Your internal cybersecurity training content highlights key risks, including phishing, ransomware, malware and social engineering, noting that 74% of account takeover attacks start with phishing.

Effective training should include:

• Recognising phishing emails, spoofing, and suspicious attachments

• Understanding social engineering tactics

• Knowing how to report suspicious activity

• Regular micro‑learning and simulated phishing exercises

Modern security awareness programmes, which use behavioural analytics and continuous training, significantly reduce the likelihood of a successful breach.

2. Deploy Endpoint Protection Software

Endpoints (laptops, desktops, mobiles) are prime entry points for attackers. Your organisation’s messaging emphasises the importance of endpoint and network protection, combined with multi‑layered security including firewalls, cloud protection and continuous threat monitoring.

Tools such as Microsoft Defender offer AI‑based threat detection, vulnerability management, and unified security operations, all key to protecting modern SME environments.

Endpoint protection should include:

• Antivirus / anti‑malware

• Endpoint Detection and Response (EDR)

• Device encryption

• Threat monitoring and alerting

  
  

3. Enforce Multi‑Factor Authentication (MFA) Everywhere

If SMEs implement only one change immediately, it should be MFA.

Industry research shows MFA stops the vast majority of automated account breaches, and your internal guidance reinforces MFA as a core control within Cyber Essentials.

Apply MFA to:

• Email accounts

• Microsoft 365 and cloud services

• Remote access tools

• Admin logins

• Banking and financial systems

MFA adds a critical additional layer of protection even if passwords are stolen or leaked.

4. Keep Systems Updated

Out‑of‑date systems are one of the biggest contributors to successful cyberattacks. Attackers frequently exploit known vulnerabilities that organisations simply haven’t patched.

Cyber Essentials emphasises Security Update Management as one of its core controls, ensuring software is kept up to date to eliminate vulnerabilities before cybercriminals can exploit them.

Your SME should:

• Enable automatic updates on all devices

• Patch operating systems, applications, browsers and plugins

• Replace unsupported hardware and software

• Regularly review vulnerability reports

Staying updated is simple but extremely effective.

5. Perform Regular Data Backups

When ransomware or data loss strikes, backups are often the difference between quick recovery and total business shutdown.

Your internal messaging heavily stresses secure backup and recovery solutions as a critical cybersecurity pillar for SMEs.

Follow best practices such as:

• The 3‑2‑1 rule (3 copies, 2 different media types, 1 off‑site)

• Encrypting all backups

• Using immutable cloud backups where possible

• Testing data is restored regularly. A backup that hasn’t been tested is a backup you can’t rely on

Backups ensure business continuity even in the worst‑case scenario.

Final Thoughts

SMEs don’t need enterprise‑level budgets to significantly improve cybersecurity. By focusing on staff training, endpoint protection, MFA, patching and robust backups, you can close the most common attack pathways and greatly increase your resilience.
