# Exostar Launches Secure CUI Collaboration

On October 6, 2026, Exostar launched Secure Exchange, an encrypted messaging and file-sharing capability for defense suppliers exchanging Controlled Unclassified Information (CUI) across organizational boundaries. The product is included in Exostar’s CMMC Ready Suite, runs in a Microsoft 365 GCC High environment described as meeting FedRAMP Moderate equivalency, and is not offered as a standalone product or government contract. Contractors remain responsible for authorized sharing and their assigned security controls; one signal also reports that CMMC Phase 1 self-assessment requirements remain in force while Phase 2 is under review.

- Defense contractors can evaluate Secure Exchange for cross-company CUI workflows and confirm that its stated environment and capabilities meet the requirements of their specific contracts.
- The product’s inclusion in the CMMC Ready Suite means organizations interested in it should assess the suite offering rather than expect a standalone purchase.
- **Why this matters:** The launch offers defense supply-chain organizations another commercial option for secure collaboration, but it does not transfer customers’ responsibility for information handling or security controls.

**Jurisdictions:** federal
**Industries:** Defense & Military, Information Technology
