PKard for Mac

Web, email & VPN with CAC/PIV for Mac

PKard® for Mac replaces the native macOS PKI solution to provide users with a solid product with full, free, U.S. based support. It is the same commercial code used by the Pentagon, all six DoD services, White House, NIH, and DOI across tens of thousands of Mac users since the mid-2000s. Our U.S. engineered PKard for Mac software meets the needs of U.S. DoD and Federal Mac users. PKard for Mac provides two-factor authentication support using a CAC, CAC Dual Persona, PIV, or PIV-I smart card to applications capable of certificate authentication via Apple’s Keychain. Some of these applications include secure websites, web VPN, and secure S/MIME email signing and encryption (with use of 3rd party mailing apps such as Apple Mail or Outlook for Mac). U.S. phone and email technical support is included. Card reader hardware and smart card ID are not included.
