The Defense Information Systems Agency (DISA) is seeking information from commercial vendors regarding a Cloud-Based Internet Isolation (CBII) service aimed at enhancing cybersecurity for the Department of Defense (DoD). The primary objective is to identify a managed service that can effectively isolate non-government internet traffic for approximately 3.6 million Non-classified Internet Protocol Router Network (NIPRNET) users, thereby mitigating cybersecurity risks and alleviating bandwidth constraints. This initiative is critical for securing DoD networks by offloading non-mission essential web traffic to a cloud environment, which will enhance overall cyber protection and streamline network operations. Interested vendors are encouraged to submit white papers detailing their proposed solutions, including training, implementation processes, and cost estimates, to the primary contact, Vanessa McCollum, at disa.scott.ditco.mbx.ps84-other-transaction-authority@mail.mil. This Request for Information (RFI) is not a solicitation for proposals and is intended solely for market research purposes.
