Digital Certificates

ECA Certificates for DoD Communication & Authentication

IdenTrust’s digital certificates are trusted by the Department of Defense (DoD) and ensure the identity of government system users

ECA certificates are required to access many online government websites and applications. Each government agency establishes guidelines pertaining to the "assurance level" that is required to access the agency system. Certificates issued under the ECA program provide the mechanism for entities to securely communicate with the DoD, authenticate to secure DoD information systems and for protection of confidential emailed communications.
