Prime contractors on Teams GCC High. DoD program offices on Webex DoD (FedRAMP High, IL4/IL5). Engineering teams on Slack. SyncRivo bridges the commercial versions of Slack, Teams, Google Chat, Webex and Zoom for unclassified collaboration. SyncRivo is not FedRAMP authorized and is hosted in a commercial US Google Cloud region (us-central1); it does not support GCC High, Webex DoD, CUI or ITAR workloads.
Defense and aerospace organizations operate across three distinct messaging layers — corporate/program coordination, CUI-compliant DoD communication, and engineering collaboration — each with different platform requirements driven by authorization level, security clearance, and tool integration.

Cisco Webex DoD
FedRAMP High · DoD IL4 / IL5 Authorized
Webex DoD is Cisco's FedRAMP High-authorized, DoD Provisional Authorization IL4/IL5 platform — hosted in dedicated GovCloud infrastructure separate from commercial Webex. It is one of the few messaging platforms authorized for DoD Controlled Unclassified Information at IL4, making it mandated for some DoD program offices, DCSA interactions, and certain agency-prime contractor communications. This creates a third communication layer in many defense organizations — separate from Teams GCC High and commercial Slack.
DoD program offices (Air Force Life Cycle Management Center, Naval Air Systems Command, Army PEO offices) may operate on Webex DoD while the prime contractor's program management office runs Teams GCC High. SyncRivo does not bridge these government environments: it is not FedRAMP authorized and connects only to the commercial versions of each platform. Where both sides also use commercial platforms for unclassified coordination, SyncRivo can bridge those channels.
Systems engineers and DevSecOps teams on Slack need to communicate with program managers, contracts staff, and executives on Teams. On commercial Slack and Teams, SyncRivo bridges the human discussion in engineering channels to the appropriate Teams coordination channels — without exposing the full Slack workspace to Teams users or vice versa. Build and test alerts posted by bots or apps are not relayed.
Defense programs span prime contractors, Tier 1 systems integrators (L3Harris, DRS Technologies, SAIC, Leidos, Booz Allen), and Tier 2 specialized subcontractors — each on a different enterprise tenant and messaging platform. For unclassified work on commercial platforms, SyncRivo partner connections bridge specific channels between organizations and can be disabled when the program phase ends. No guest accounts required.
Defense M&A — Raytheon merging with UTC, L3 merging with Harris, private equity acquisitions of defense technology companies — creates immediate cross-platform communication challenges. The first channel bridge is typically live during onboarding, once your Slack/Teams admins approve the app. Both sides continue on their native platforms while integration and IT consolidation progresses. No forced platform migration before organizational decisions are made.
Defense and aerospace messaging bridges often must satisfy CMMC 2.0, ITAR, FedRAMP and DoD data requirements. SyncRivo is not FedRAMP authorized, has not been assessed for CMMC 2.0, and is hosted in a commercial US Google Cloud region (us-central1). Here is what SyncRivo does and does not provide.
SyncRivo has not been assessed against CMMC 2.0 and is not designed to carry Controlled Unclassified Information. Use it only for unclassified, non-CUI collaboration.
Message content is not stored on the normal relay path; only message IDs are kept. An optional retry queue temporarily holds undelivered messages. SyncRivo is not designed for ITAR-controlled communications.
SyncRivo is not FedRAMP authorized. It is hosted in a commercial US Google Cloud region (us-central1) and connects to the commercial versions of each messaging platform, not Teams GCC High or Webex DoD.
SyncRivo does not currently hold a SOC 2 report; we provide a security questionnaire and architecture review on request.
Messages flow only between the channels you bridge. Admins control which channels are connected, and connections can be disabled or deleted at any time.
