Defense Collaboration Services (DCS) enables synchronous communication among the Non-secure Internet Protocol Router Network (NIPRNet) and Secure Internet Protocol Routing Network (SIPRNet). The capability includes Web Conferencing (session management, text messaging, application sharing/broadcasting, audio, presence and awareness, voting/polling, video, multiple sessions, and recording) and Instant Messaging (IM).

DCS supports Common Access Card (CAC) and select hard token holders and unanticipated (select DOD mission partners) users. Anticipated users are issued accounts which authorize privileges to manage/control collaboration sessions, whereas unanticipated users are provided ad hoc guest access without pre-specified roles/permissions.


DCS can scale to handle 10,000 concurrent users with a maximum of 250 participants per web conference. Mission partners requiring collaboration above 250 participants can leverage DISA’s Global Content Delivery Service (GCDS) in lieu of DCS. The DCS Chat service is scalable to support 100,000 concurrent users.

Service Continuity

DCS ensures continuity of operations (COOP) through a fault-tolerant design. DCS can tolerate the failure of one of any type of component. The system is designed to continue operating in the event of a single failure of any one component in the primary site.
