Internet Banking Security

Keep your Internet banking session secure

Check the site is secure

When you visit a website (especially a transaction website) you should look for a padlock in the browser window. The padlock indicates that you are in SSL (secure socket layer) mode, which means that every request or information that you send from the browser to our secure site is encrypted (scrambled and encoded).

FNB uses Entrust Digital Security to encrypt information.

The Entrust Site Seal makes it possible for our Online Banking customers to transact and share information free of worry.

Web browsers

The FNB website is designed to be accessible via all main web browsers and browsing devices. We recommend that you use the latest version of your preferred browser. The most up-to-date version of your preferred browser is normally available as a free download from the relevant browser manufacturer's website.

The latest versions of browsers are more secure than older versions, which is particularly important when doing your banking via the Internet.

Most Windows based PCs are preinstalled with Microsoft Internet Explorer (IE), therefore it is the most commonly used browser. Because of this, IE is the browser most attacked by viruses and spyware.

If you use IE it is particularly important to run a virus scanner regularly and keep it updated with the latest security patches from Microsoft.

Other good browsers for Windows PCs, such as Opera and Mozilla Firefox, are available free of charge.


Internet browsers have the ability to remember a page from a website - this is called caching. This makes Internet surfing quicker because when you return to a web page, the browser can present a stored page without having to request the page from the server again.

For security, all FNB Online Banking pages are delivered with instructions to the browser not to cache (remember) the information. While most browsers obey these instructions, Internet Explorer (IE) ignores them and under certain circumstances you may view a cached page of information.

To prevent this make sure that IE has the following settings:

  • >Tools > Internet Options > Advanced > Do not save encrypted pages;

  • >Tools > Internet Options > General > Settings > Automatically;

  • >Tools > Internet Options > Advanced > Empty Temporary Internet Files folder when browser is closed;
