Protect your information, control access, and ensure secure meetings on a daily basis.

How does Microsoft Teams protect your information?

Microsoft Teams was developed to facilitate collaboration without compromising information security and user privacy. The platform integrates automatic and configurable features that protect data, files, and meetings.

Data protection
Messages, files, and meetings are encrypted in transit and at rest, ensuring the confidentiality of information.
To learn more about compliance and data protection in Microsoft 365, see the official Microsoft documentation here.

Access control
Only authorized users can access teams, channels, and meetings. It is possible to define who can share content, record meetings, or admit participants.

Meeting security
Features such as waiting rooms, participant control, and recording options help keep meetings secure and under control.

Compliance and privacy
Microsoft Teams complies with international security and privacy standards, including GDPR, ensuring responsible use of personal data.
To learn more about privacy and data usage by Microsoft, see the Microsoft Privacy Statement here.
