Staying safe online

Scams that target businesses

Learn about the main types of scams your staff need to be able to recognise to protect your business.

Steps you and your staff can take

Keep your technology up-to-date

Consider installing:

  • Automatic updates for your software, which often have security features
  • Anti-virus software 
  • Software only from trustworthy suppliers, like the Microsoft Windows Store or Apple’s App Store

Also think about:

  • Limiting admin access on your computers, to control who can install new programs and change security settings
  • Encrypting your hard drives

Secure your office network

You may need professional help to: 

  • Change the default password for your router
  • Hide your office network so people don’t try to log in to your Wi-Fi
  • Create a guest mode for visitors, such as temporary staff, so they can use internet but not other services
  • Turn off features you don’t use to reduce vulnerability
  • List approved network devices, so you can remove access when it’s no longer needed

Keep safe in the cloud

When using cloud services like email or file storage, ensure you:

  • Understand where the service operates, the privacy laws it follows, if it shares data with third parties and how you'll be notified of service outages or security breaches
  • Set controls so staff have appropriate access
  • Confirm your provider encrypts your data, whether it’s sent and stored
  • Create local backups
  • Keep checking your provider is still suitable as your business grows
