ENTERPRISE EMAIL SECURITY GATEWAY (EEMSG)

PRINT PAGE Add This

The Enterprise E-mail Security Gateway (EEMSG) capability is one of several critical NIPRNet Hardening capabilities deployed by the Defense Information Systems Agency (DISA). EEMSG simultaneously meets USCYBERCOM requirements for defense of the DoD Information Networks (DoDIN) while providing multiple operational communities and end users the mission assured environment required to execute Net-Centric Warfare. EEMSG is a USCYBERCOM planned/directed mandatory capability that provides defense-in-depth protections to existing service-level and enclave-level email systems. All components on the NIPRNet will be required to have inbound e-mail traffic routed through EEMSG. EEMSG is being deployed in three capability phases:

  • Phase 1 - Inbound (Internet-to-NIPRNet) e-mail protection-Current
  • Phase 2 - Outbound (NIPRNet-to-Internet and NIPRNet-to-NIPRNet) e-mail protection - Future
  • Phase 3 - Inbound encrypted e-mail inspection - Future

STANDARD FEATURES


EEMSG provides the following services for the protection of DoD Email Domains:

  • Antivirus
  • Spam Filtering
  • Content Filtering
  • Sender Spoofing Detection
  • Spear Phishing Detection
  • DLP/PII policy
  • 30 MG message limit

OPTIONAL FEATURES


The EEMSG provides a standard DoD-wide email security policy.  No optional features are available.

VALUE TO OUR MISSION PARTNERS


The deployment of EEMSG potentially allows enclaves to consider eliminating e-mail scanning systems that duplicate the capabilities of EEMSG and may be neutered to some extend (e.g., sender IP reputation) with EEMSG in the path.
