The Defense Counterintelligence and Security Agency (DCSA) Office of the Chief Information Officer (OCIO), intends to solicit and negotiate directly with Microsoft Corporation, 1 Microsoft Way, Redmond, WA 98052-8300, CAGE 60128 for Microsoft (MS) Unified Enterprise Support Services (UESS). DCSA requires these comprehensive, proactive support services for its enterprise-wide Microsoft product ecosystem. This support must include guaranteed response times and encompass all DCSA locations. DCSA seeks to ensure optimal performance and stability of its critical Microsoft infrastructure. Microsoft Corporation is the sole provider of MS UESS and retains exclusive rights to underlying MS intellectual property. Due to this inherent exclusivity, only Microsoft can provide critical functionalities such as direct access to Microsoft engineers, proactive services, official updates/patches, ongoing maintenance/optimization, and dedicated account management. Duplicating these proprietary services with another vendor is technically infeasible and would introduce unacceptable risks, including compromised system stability, security vulnerabilities due to delayed or unofficial patching, decreased performance, and a lack of direct access to Microsoft's expertise for critical issue resolution, potentially jeopardizing mission-critical operations. While this notice of intent is not a request for competitive quotes, interested parties may submit a capability statement demonstrating their ability to provide services identical.to MS UESS, including key functionalities that only Microsoft can provide, e.g., direct access to source code, proprietary update mechanisms, authorized patching, etc. This statement must include detailed technical documentation with specific evidence supporting the claim. Generalized marketing materials will not be considered. Submissions must be received via email no later than 12:00 PM EDT on August 01, 2025. The Government will review all qualifying submissions before proceeding with the sole source award to Microsoft. The Government will not be responsible for any costs incurred in the preparation of responses to this announcement. This is the only notice that will be issued for these items. A determination by the Government not to compete this proposed contract based upon responses to this notice is solely within the discretion of the Government.
