Why do I receive a security alert when accessing NAB Internet Banking?
NAB Internet Banking uses digital certificates issued by VeriSign to ensure your connection is protected.
From January 2003, VeriSign discontinued support for digital certificates installed in earlier versions of Internet Explorer 5.0 (IE 5.00.2614).
NAB Internet Banking customers using these browsers will be affected. You'll encounter a security alert message whenever you attempt to enter a secure session. You'll have the option to continue and if you choose to do so, your session will still be encrypted.
To avoid the security alert in the future, we recommend that you upgrade your browser to a supported version.
Further information about digital certificates can be found at the VeriSign Australia, digital certificate tutorial page.
