A Magento Security Extension


What is Alarmbell?

Developed by Nexcess engineers, Alarmbell is a new open source extension that logs and sends notifcations whenever a new admin user is created. Alarmbell logs the IP and account information of any attempt to make changes to admin users, including their creation, deletion, and modification.

We built Alarmbell to work with your organization. Alarmbell offers fully configurable notificaiton emails to help immediately notify the right people about any changes to a store's admin users.


  • All create, edit, and delete actions on admin user records are logged to the standard system.log; IP address and account information of any user making such changes are recorded.
  • All successful and unsuccessful admin login attempts are logged to the standard system.log with that user’s IP address and username.
  • Can be enabled and disabled as needed.
  • Can be configured to send customized email alerts.
