Barracuda Sentinel, Office 365, and Azure AD

Barracuda Sentinel monitors licensed Office 365 mailboxes.

Note that in hybrid email deployments, Barracuda Sentinel only monitors Office 365 mailboxes; Barracuda Sentinel does not monitor mailboxes that are part of on-premises solutions.

For Account Takeover suspicious sign-in data, Barracuda Sentinel requires full Azure AD (Active Directory) tenants. It does not always receive sign-in data from hybrid environments that include both on-premise active directory and Azure AD. 


Connecting Your Office 365 Account to Barracuda Sentinel

This process requires Office 365 global tenant administrator credentials.

Complete the following steps so Barracuda Sentinel can protect your Microsoft Office 365 account:

  1. Sign up with your username and password at If you already have a Barracuda Cloud Control account, you can use the same credentials to sign in to Sentinel.
  2. When Office 365 opens, log in as a global tenant administrator. 

  3. Review the permissions required by Barracuda Sentinel and click Accept.

    After signing up, Barracuda Sentinel will take anywhere from several hours to several days (depending on the size of your account) to fully learn your environment. Once the initial learning phase is completed, you will receive an email notifying you that your Barracuda Sentinel dashboard is now available.

Note that if you add mailboxes to your Office 365 account at a later date, Barracuda Sentinel requires up to 72 hours to learn about these new mailboxes and begin monitoring and protecting them.
