Barracuda Email Security Service (ESS) now allows end-users, to access their message log without entering the password or even going to the ESS UI.
Many companies have a portal where their end users go to see all the authorized app. Now ESS can be added to that portal page by a company. The documentation for that is https://campus.barracuda.com/product/essentials/doc/91980697/how-to-configure-the-barracuda-email-security-service-app-in-azure-ad
Once the admin adds the ESS app to their portal page, end users can just click ESS in their portal page and they will be taken to their ESS message log without having to log in!! Right now, this is supported for Azure AD. We are looking into Okta integration. We are calling this feature password-less login for ESS end users instead of SAML integration since SAML is a technology and does not explain the benefit.
Here is a screenshot of how the portal will look for an end user – note ESS in the picture below.
