Protect your business technology

It’s important to protect your business devices, like phones, tablets, laptops, and computers . This helps keep them safe from fraud.


  • Make sure you have the latest anti-virus software on your devices and run regular checks on your computers.
  • Always use the latest version of your operating system.
  • Install security updates as soon as they’re available.
  • Back up your data regularly.
  • Turn on the firewall on all your devices.
  • Learn how to spot signs that your computer may be infected, such as:
    • Apps not working right.
    • The last login date not matching your last login.
    • Slow, freezing, or crashing systems.
    • Strange error messages.
    • Changes to your browser toolbar.
    • The system slows down for no obvious reason.
    • More files than you added.
    • Printing issues.
    • Screen looks strange.
    • Files change size for no reason.
  • If you think your device is infected, don’t log into any online banking until the problem is fixed by a security expert.
  • Teach your employees about fraud and how to avoid it.
