>Q. What level of security and compliance does Microsoft Teams support?
>A. Microsoft Teams is expected to be Office 365 Tier C compliant at launch. This broad set of global compliance and data protection requirements includes ISO 27001, ISO 27018, EUMC, SOC 1 Type I & II, SOC 2 Type I and II, HIPAA and FERPA. Microsoft Teams also enforces two-factor authentication, single sign on through Active Directory and encryption of data in transit and at rest.
The last time I'd looked into it, Slack was explicitly not HIPAA-compliant and therefore a non-starter for my team. We've basically had to stick to a combination of Hangouts for general chat and internal email for any HIPAA-covered data, so this would be a big win for us.
