Cyber threats are no longer just a concern for large corporates. Small and medium-sized enterprises (SMEs) are increasingly finding themselves in the firing line, with phishing, ransomware, and supply chain attacks becoming more frequent and damaging.

As the threat landscape evolves at speed and digital dependence continues to grow, many SMEs remain unprepared, lacking both the in-house expertise and the strategic support to build wide-scale cyber resilience against cyber attacks and data breaches.

Beazley, the leading specialty insurer, is urging SMEs to take proactive steps now to protect their businesses and build an ecosystem of cybersecurity. Drawing on its experience in managing and mitigating cyber exposures globally, Beazley shares its top five cyber tips – and one mistake no business can afford to make.

Five things SMEs should do:

1. Train your team – regularly.

While your people are your greatest asset, human error remains the weakest link. Equip employees with the tools to spot and report phishing and social engineering attempts through regular, simulated training.

2. Update, patch, repeat.

Outdated software is a cybercriminal’s dream. Keep systems, applications and security tools up to date with scheduled patching and end-of-life assessments.

3. Embrace multi-factor authentication (MFA).

Strong, unique passwords aren’t enough. Use MFA across all systems to protect against credential theft and unauthorised access.

4. Know your weak spots.

Commission regular vulnerability scans, port testing and threat assessments to uncover and fix gaps before attackers exploit them.

5. Plan for the worst.

A robust incident response plan, backed by specialist cyber insurance, means you’re not alone in a crisis – and can recover faster.

One thing SMEs should never do:

Rely on IT providers to do it all.

Outsourcing doesn’t outsource risk. Make sure you understand your responsibilities, scrutinise cloud provider agreements, and verify their security and monitoring practices.

Sam Franks, Country Manager & Head of Partner Engagement UK & Ireland at Beazley, commented:

“The cyber threat landscape is evolving rapidly – and SMEs are right in the firing line. Cybercriminals are becoming more organised and opportunistic, using increasingly sophisticated tools to exploit even the smallest vulnerabilities. The rise of remote working, digital payments, and cloud-based systems has expanded the attack surface for businesses of all sizes.”

“There is a full spectrum of cyber risks and for SMEs, the risks are especially high – from business email compromise and malware infections to third-party software vulnerabilities and insider threats. Without an effective defence and policy in place, a single incident can lead to severe financial loss, operational disruption, and reputational damage.”
