Online security

ANZ employs a range of security measures to assist in protecting your personal account information. These measures extend from data encryption to firewalls. Firewalls, together with encryption technology help to provide some of the best security available to keep your PIN, password, User ID and account information protected.


Encryption is turning words and numbers into a coded language. Encryption prevents unauthorised users from being able to change or read your data. ANZ encrypts your personal data using 128-bit SSL (Secure Socket Layer) encryption technology. You can identify whether the Internet Banking session is secure or encrypted when you see <https://> in the address bar and/or when you see a padlock in the bottom right corner of the browser window. You can double click on the padlock to examine ANZ’s electronic signature.

ANZ employs a firewall to prevent unauthorised access to and from the network. A firewall acts as a barrier between your computer and the Internet. This helps ensure that only authorised data enter and leave your computer, much like a security guard in front of a building.



Automatic time-outs

Within the ANZ Internet Banking system, a default of 15 minutes has been set as the amount of time your banking session can remain unattended. After this time, the system automatically "logs off" and ends your session.

If you are not using your computer for an extended time, make sure you "log out" completely from the ANZ Internet Banking session so that your banking information cannot be viewed by others.
