From Breaches to Best Practices: Cybersecurity Lessons for SMEs
Cybersecurity threats to small and mid-sized businesses have fundamentally changed. AI-powered attacks surged by 442% in 2024 alone, with criminals using sophisticated tools to impersonate executives, bypass security systems, and exploit human trust at unprecedented scale.
The barriers that once protected smaller businesses such as limited visibility, basic security measures, trusted suppliers are now the very vulnerabilities attackers target.
This whitepaper analyses five major security breaches that made headlines around the world, including:
- The £300 million Marks & Spencer ransomware attack
- Samsung's AI data leak, and
- The £20 million Arup deepfake fraud.
Through detailed case studies and expert analysis from FLR Spectron’s security team, we break down exactly how these attacks succeeded, what went wrong, and what smaller businesses can learn from these high-profile breaches.
The analysis reveals four critical truths
Supply chains are your biggest vulnerability
Attackers don't break in anymore, they log in
AI has dramatically lowered the skill barrier for cybercrime
Basic security is no longer sufficient
Moving beyond technical jargon, this report provides SME leaders with a practical three-step framework for building cyber resilience: understanding your risks, implementing modern defences, and preparing your people for AI-enhanced threats. Each case study includes clear, actionable lessons directly applicable to businesses operating under real-world constraints of limited budgets and resources.
