What is Direct?
Launched in March 2010 as a part of the Department of Health and Human Services Nationwide
Health Information Network, Direct is a peer to peer messaging standard that has been rapidly
adopted as a secure, scalable, standards-based way for providers to send authenticated,
encrypted health information directly to known, trusted recipients over the Internet. Direct uses
SMTP, S/MIME, and X.509 certificates to securely transport health information over the
Internet. Direct uses standard e-mail addresses associated with X.509 certificates. Providers are
using Direct secure messaging today to comply with Meaningful Use requirements for incentive
payments from Centers for Medicare and Medicaid Services (CMS).
