Protect your business online

10 cyber security tips to protect your business online

Guide

Cyber attacks threaten all businesses. A recent government survey found that many organisations, including small businesses and charities, have experienced cyber incidents. Larger businesses face more frequent attacks, but any business without proper defences can be vulnerable.

How to protect your business online

The National Cyber Security Centre (NCSC) recommends these actions:

  • Back up data regularly. Keep copies of your data off-site and test that backups work.
  • Update software promptly. Apply security patches on all devices used in your businesses. Enable auto-updates where possible.
  • Use anti-virus and anti-malware software. Keep it up to date.
  • Choose strong, unique passwords. Change them regularly and use two-factor authentication.
  • Encrypt sensitive data. Never send passwords or sensitive details via unencrypted email.
  • Be cautious of phishing and ransomware. Avoid clicking on suspicious links in emails or social media.
  • Use firewalls and keep router firmware updated.
  • Secure Wi-Fi with encryption (e.g. WPA2). Change Wi-Fi passwords regularly.
  • Use a VPN when connecting over public or external networks.

For detailed guidance, check the NCSC's cyber security advice for small and medium-sized businesses.
