Teams is a part of Office 365, which means it has met certain compliance commitments. There are four levels of security standards within Office 365 - Tier A, B, C, and D which all have different controls for enabling and disabling services. Teams is a Tier D-compliant product, which means it has stringent compliance measures enabled by default. This is an essential security precaution for a tool that is typically installed at the team or departmental level without the intervention of an IT department. Sometimes, Teams is installed at the individual level, such as on personal mobile devices or computers.
Speaking of devices, Microsoft has also built mobile app management into Teams via settings in the Office 365 Security and Compliance Center. There, managers can use Microsoft Intune for advanced data configuration on devices used by employees and partners.
Once again, data can be stored in several locations when in Teams, so another important data protection measure includes two-factor authentication for everyone in the organization from within Active Directory – another benefit of Team’s status as a member of the Office 365 family. Data is encrypted at rest and in transit, and stays in the region where your headquarters are located or, more precisely, where your Office 365 tenant is registered. There are region-specific data storage services for a number of countries and regions, detailed here on the Microsoft website.
One default security measure that comes enabled by default is limited access to guest users. Within this context, a guest user is someone who does not have an email address that’s hosted with your company (firstname.lastname@example.org). And even if someone wants to enable guest access, only an administrator can do this.
Despite all this, you still need to secure data that’s spread out in many different areas of the cloud, and accessed by many different classes of users – which is an undertaking on its own.
