Microsoft has released a preview of their new security analytics service called the Office 365 Secure Score. The Secure Score is a security analytics tool that will help administrators understand what they have done to reduce the risk to their data in Office 365, and show them what they can do to further reduce that risk. Think of this as a credit score for security. This feature is available for all multi-tenant customers in preview as of the 10th October 2016.
The Office 365 Secure Score is designed to help administrators quickly evaluate and communicate about their risk across all Office 365 services and to help them take incremental action to improve their overall security. Administrators don't have to do anything to enable it. The service collects and analyses the configuration for automatically, and allows administrators to quickly evaluate their options, then take the action most appropriate for your organisation.
