What security measures has NAB put in place?

Security for communications and transactions over the Internet is important for both NAB and our customers, and we'd like to let you know that the NAB Internet Banking security system has been selected by our data security experts following extensive research.

To help deliver secure Internet Banking services, NAB has implemented a solution that seeks to provide robust authentication and privacy.

NAB uses TLS (Transport Layer Security) encryption technology to protect your information. To ensure compatibility with our site, please keep your browser up to date.

In addition to our sophisticated cryptographic implementation, robust firewall technology is employed to help to protect NAB's internal systems and customer's information against intrusion from the Internet.

For greater security NAB Internet Banking has the facility to allow you to voluntarily lock your password when logging out from the application. NAB Internet Banking cannot be accessed again until your Internet Banking password is unlocked. To unlock your Internet Banking Password you need to call 1300 651 656 and enter your Telephone Banking Password when prompted.

We also have a special security software offer for all NAB customers. Visit nab.com.au/software for more information.

NAB has introduced these measures to help provide a secure environment for you to complete your banking. Find out more.

Why have you introduced Password lock?

The ability to lock your Internet Banking password has been introduced to provide security aware customers with a tool which offers peace of mind when banking with NAB. Password lock now provides customers with control over the level of protection they wish to adopt.

This feature is ideal for people banking in environments that are outside of their control (e.g. Internet Cafes).
