We've launched an update which now provides IP address access control on accounts, notebooks and idea portals. This new feature allows you to control who can access your Aha! account based on IP addresses and is available specifically for Enterprise+ customers. This new feature is available in Account settings, under the Security and single sign-on page.

Note that you can already require that users enter a password before viewing a notebook by using the Enhanced Notebook Security control under Settings -> Account -> Security and Single Sign-on.
