  • The percentage at which to alert if login percentages fall under

Problem: This alert is triggered when the total number of successful logins to your tenancy falls below a pre-set percentage.  This may be due to your team members failing to authenticate in a non-malicious manner, or it could also be an attempt from an external party to gain unauthorised access.

Suggested steps: Engage a technician to confirm that the alert is accurate, and if so then the technician should suggest and undertake any possible authentication and authorisation hardening improvements.
