What are the most common cyber threats to UK SMEs in 2026?

Skip to main content

The most common threats are:

  • Phishing: now often written by AI and very convincing.
  • Email account takeover and invoice fraud: criminals get into an email account and redirect payments.
  • Ransomware: your files are locked until you pay.
  • Attacks on unpatched software and remote access.
  • Deepfake voice or video scams: impersonating a director.

Most attacks still start with a stolen password or a clicked link. That’s why MFA, updates, backups and staff training stop the majority of them. To stay ahead, treat security as an ongoing process, not a one-off project. See our cyber security services.
