Microsoft is now using Transport Layer Security (TLS) encryption for both outbound and inbound email on Outlook.com.
In addition to the TLS, Microsoft has enabled Perfect Forward Secrecy (PFS) encryption support for sending and receiving mail between email providers and in its OneDrive service, according to a news release. The new security announcements follow Microsoft's December statement that it would be expanding its encryption across services and reinforcing customer data protections.
Not only is the company increasing its virtual security, but it also opened its first physical “Transparency Center” earlier this week in Redmond, Wash. The center will assist governments with reviewing source code for its products and proving their integrity, as well as the fact that no back doors exist.
