Organizations work on various procedures, work processes, and strategies that manage who gets and sends delicate messages and information. Office 365’s default security settings don’t automatically protect your business. You have to configure them to fit your association.

Set up a user-by-user premise, multi-factor authentication supplements a strong password policy. It checks their login, whether clients are signing in from the workplace IP address, or their local Starbucks.
