Are you Minimizing your Risk by using the Next Generation of Opt In Email Encryption?

September 11, 2015

We have long held that leaving it to each sender/employee to properly enable encryption for each sensitive message (a.k.a “Opt In Encryption”) is too risky.  Why?

This is especially important for customers who need to be HIPAA-compliant, as email transport encryption over TLS is sufficient for HIPAA-compliant communications to end-users, so long as the TLS is configured to be sufficiently strong. While it is possible to tell who supports […]
