What SMEs Can Learn from the M&S Attack

In April, Marks & Spencer suffered a ransomware attack that encrypted critical servers, bringing contactless payments, online orders, and click-and-collect services to a standstill. Recovery took 15 weeks and even a company of that scale felt the impact.
Key Takeaways for SMEs:
1. Prevention is cheaper than recovery
- Invest in endpoint protection and maintain regular, tested backups.
- A breach for a small business could mean permanent closure.
2. Time is the real cost
- Early detection and proactive threat monitoring limit downtime and financial loss.
3. Incident response isn’t optional
- Have a clear, tested response plan:
- Key contacts (internal & external)
- Steps to isolate affected systems
- Communication plan for customers, suppliers and staff
4. Cybersecurity is a team sport
Social engineering caused the initial breach. Staff training, awareness, and strict password policies are critical to stopping attacks before they spread.
SME Takeaway:
Even the biggest brands need weeks to recover from attacks. SMEs can’t afford that delay. Prevention, preparation and lightweight, scalable defenses are key to survival.
