Description— Fourth Estate Network Optimization (4ENO)
Department of Defense Network (DoDNet) is a common information technology (IT) environment, network consolidation effort directed by the Deputy Secretary of Defense in the memorandum, "Fourth Estate Network Optimization Execution Guidance" on 15 August 2019. The Defense Information Systems Agency (DISA) has been designated as the Department of Defense's (DoD's) Single Service Provider (SSP) for DoDNet. The DISA is working to consolidate the commodity IT local area networks and service desks associated with 14 Defense Agencies and Field Activities (DAFAs). The goal is to migrate disparate, separate organizational networks onto a single DoDNet. Following migration, each DAFA will use the DoDNet as their primary network in a common IT environment. Migration to DoDNet promotes Zero Trust compliance as migrating DAFAs will have Thunderdome Zero Trust capabilities from Day One. Beyond FY 2026, DISA will look to bring additional DAFAs and Combatant Commands onto DoDNet. Migrating the entire DoD to a common IT environment supports the Priority of Rebuilding the Military by ensuring maximum efficiency and effectiveness, removing redundancies and reducing waste within the Department. The entire migration process is iterative with several stages that span across fiscal years, including virtual and physical site surveys, planning and design (determining the equipment needed based on surveys), equipment purchase, installation, and integration. Each DAFA migration to the DoDNet begins with a site survey and technical assessment of the legacy network. DAFAs possess varying quality of IT infrastructure, and connection to the DoDNet requires modern equipment. Following a site survey, during planning and design, the DoDNet PMO identifies the network equipment requiring replacement prior to migration. The DoDNet PMO then purchases, receives, and installs replacement equipment. DISA spends procurement only when DISA is ready to purchase equipment for the DAFA. Migration involves integrating the new equipment and existing standardized equipment into DoDNet and then migrating users. Once successful migration occurs, the DAFAs require recurring technical refresh to keep the networks operating effectively and securely. DISA is beginning tech refresh on equipment purchased in FY 2021 for DISA, Defense Prisoner of War/Missing in Action (POW/MIA) Accounting Agency (DPAA) and the Defense Technical Information Center (DTIC). Ongoing tech refresh is necessary for a seamless user experience. In addition to agency migrations, the DoDNet PMO must procure equipment to operate and secure the DoDNet Service Centers. DoDNet Service Centers connect various DoD Agencies to the DoDNet interface. Whenever personnel use a Virtual Private Network (VPN) or onsite connection, they connect to DoDNet via a DoDNet Service Center. Upgrades and build-out ensure that the DoDNet Service Centers can handle additional workloads; otherwise, user experience for DoD personnel would be dramatically compromised. The DoDNet Service Centers enable user access to the DoDNet and require up to date servers and IT infrastructure. Equipment at DoDNet Service Centers enables DAFAs to connect to DoDNet Service Centers and requires periodic refresh. Phase I (FY 2021 – FY 2026) covers the migration of an initial 14 DAFAs to DoDNet. As of May 2025, three DAFAs have completed DoDNet migration: DISA, DPAA, and DTIC, connecting 22,370 users to DoDNet. Phase I was originally supposed to conclude in FY 2025. However, DISA experienced schedule delays. Originally, these delays emanated from a protest on the award of the main Leidos contract. This delayed work due to delayed contract negotiations and agency agreements. Then, DISA was expecting customers to provide significant contributions to migration costs and was planning to supplement customer contributions with appropriated funds. Customers often had difficulty identifying sufficient funds and delayed entering into Memoranda of Agreements (MOAs) with DISA. In response, DISA developed a new strategy to expedite migrations in coordination with OSD. The DoD will not meet Zero Trust targets without DoDNet migrations. DoD is allocating significant appropriated funding to DoDNet (O&M to support planning and design, migration coordination and procurement to purchase and install hardware), migrating user end points prior to migrating network IT, and achieving Zero Trust compliance immediately following migration. DISA has re-baselined the DoDNet migration schedule and extended the migration periods: Migration FY 2021 – FY 2022 Defense POW/MIA Accounting Agency (DPAA): 11 sites; 871 users Defense Technical Information Center (DTIC): 3 sites; 483 users Migration FY 2021 – FY 2024 Defense Information Systems Agency (DISA): 29 sites; 21,016 users Note: DISA completed user account migration in FY 2023 but continued migrating additional endpoints in FY 2024. Some users who already had DoDNet account received the devices to regularly use DoDNet in FY 2024. Migration FY 2023 – FY 2026 Defense Contract Management Agency (DCMA): 342 sites; 11,077 users (Migration and purchases underway as of May 2025) Defense Contract Audit Agency (DCAA): 260+ sites; 4,491 users (Migration and purchases underway as of May 2025) Defense Media Activity (DMA): 28 sites; 1,444 users Defense Threat Reduction Agency (DTRA): 18 sites; 5,166 users Defense Logistics Agency (DLA): 200+ sites; 29,240 users Migration FY 2024 – FY 2026 Defense Finance and Accounting Service (DFAS): 10 sites; 13,100 users Defense Microelectronics Activity (DMEA): 1 site; 300 users Migration FY 2025 – FY2026 Defense Manpower Data Center (DMDC): 12 sites; 2,742 users Missile Defense Agency (MDA): 9 sites; 16,140 users Defense Advanced Research Projects Agency (DARPA): 3 sites; 1,400 users Joint Service Provider (JSP): 31 sites; 65,000 users Totals (Phase I), Sites: 957+; Users: 172,470 Note: Active migrations ongoing / overlapping across multiple fiscal years. Migration activities include site surveys, planning and design and installation / integration (replacement of outdated equipment / migration of users to DoDNet). User counts represent most recent reports. (Phase II) DoDNet PMO will develop a Phase II schedule to begin migrating Combatant Commands (CCMDs) to DoDNet. Phase II will also involve refreshing the equipment used to support initial Phase I migrations on a five-year replacement schedule with 100% replacement by the fifth year. By moving DAFAs to DoDNet, DISA will significantly strengthen the cybersecurity of the Fourth Estate and drive uniform adoption of enterprise services for core IT. DoDNet migration will reduce duplicative IT and simplify network administration with the goal of providing an advanced, safeguarded, and consolidated network (DoDNet) integrating state-of-the-art Zero Trust capabilities. The establishment of DoDNet helps rebuild the military by providing the 4th estate with a common, modern network and reduces duplicative IT infrastructure.
Justification— Fourth Estate Network Optimization (4ENO)
FY 2024: $29.677M: DoDNet Equipment/Agency Migration Support: Tech refresh is a prerequisite for DoDNet migration. Many DAFAs do not have DoDNet compliant infrastructure. The DoDNet Program Management Office (PMO) conducts site surveys to determine the level of tech refresh required at each agency. Costs associated with tech refresh vary due to the size of the DAFA and the quality of the current equipment. FY 2024 included the following activities: • Acquired network infrastructure hardware (HW) to upgrade/tech refresh outdated equipment at multiple DAFA site locations. Modernized infrastructure requirements are determined by the number of DAFAs, site sizes, cabling/integration, design and install of all-new network equipment. After deployment and integration, this effort consolidates multiple networks into a single, centrally managed network. • Completed tech refresh of outdated, end-of-life equipment and provided enhancements to standardize network infrastructure, improve network cybersecurity, and strengthen network resilience across the DoDNet environment. Hardware also supports network monitoring capabilities critical for network discovery and service performance. These capabilities help to identify and mitigate service issues quickly. Deployment of hardware, software, and network monitoring capabilities provide the ability to adjust to changes in DoD/Agency priorities and needs. These tools also reduce the growth of redundant IT systems and increase the visibility of all network-connected devices. • Procured hardware to replace outdated equipment with updated tools that can be integrated into the DoDNet environment. According to the rebaselined schedule, the DoDNet PMO started the migration process for two new Agencies in FY 2024 for a total of eight active migrations. The DoDNet PMO purchased network hardware and software to migrate Agencies to DoDNet securely and safely. DoDNet Service Centers: • Purchased hardware to equip two DoDNet Service Centers with new servers, which connect various DoD Agencies to the DoDNet interface. New hardware strengthens DoDNet Service Center capabilities to provide seamless connectivity to DoDNet. In addition, continual work is needed to ensure that Service Centers can handle additional user workloads. Otherwise, DoD personnel's user experience will be downgraded significantly. Modern equipment will also facilitate the deployment of the Thunderdome enhanced Zero Trust security capability. FY 2025: $24.482M: DoDNet Equipment/Agency Migration Support: Many DAFAs do not have DoDNet compliant infrastructure. The DoDNet PMO must conduct a Tech refresh for DoDNet migration to occur. The DoDNet PMO conducts site surveys to determine the level of tech refresh required at each agency. Costs associated with tech refresh and replacement vary due to the size of the DAFA and the quality of the current equipment. FY 2025 will include the following activities: • Acquire network infrastructure hardware (HW) to upgrade/tech refresh outdated equipment at multiple DAFA site locations. Modernized infrastructure requirements are determined by the number of DAFAs, site sizes, cabling/integration, design and install of all-new network equipment. After deployment and integration, this effort consolidates multiple networks into a single, centrally managed network. • Tech refresh of outdated, end-of-life equipment and provide enhancements to standardize network infrastructure, improve network cybersecurity, and strengthen network resilience across the DoDNet environment. Hardware will also support network monitoring capabilities critical for network discovery and service performance. These capabilities help to identify and mitigate service issues quickly. Deployment of hardware, software, and network monitoring capabilities will provide the ability to adjust to changes in DoD/Agency priorities and needs. These tools will also reduce the growth of redundant IT systems and increase the visibility of all network-connected devices. • Procured hardware will replace outdated equipment with updated tools that can be integrated into the DoDNet environment. DoDNet PMO has a total of 11 active migrations in FY 2025. With the new strategy, 57,038 NIPR/SIPR users are planned to migrate to DoDNet. The DoDNet PMO is purchasing network hardware and software to migrate agencies to DoDNet securely and safely. DoDNet Service Centers: • Purchase hardware to equip Service Centers with new servers, which connect various DoD Agencies to the DoDNet interface. New hardware strengthens DoDNet Service Center capabilities to provide seamless connectivity to DoDNet. In addition, continual work is needed to ensure that Service Centers can handle additional user workloads. Otherwise, DoD personnel's user experience will be downgraded significantly. This is also facilitating the deployment of the Thunderdome enhanced ZT security capability. Life Cycle Refresh for Migrated Agencies: DAFAs require lifecycle technical replacements to keep the networks operating effectively and securely after successful migration. Replacements are expected to begin in FY 2025 on equipment purchased to support the initial migrations: • Conduct lifecycle technical refresh of agencies already migrated to DoDNet after four years. DoDNet is on a five-year equipment replacement lifecycle that will start four years after the equipment is purchased. Replacements of equipment will begin in FY 2025 for the three agencies already migrated to DoDNet (DISA, DPAA, and DTIC). The first year of tech refresh will average 40% of completion across the board, and 100% by the 5-year lifecycle replacement mark. Explanation of Change from FY 2024 to FY 2025: -$5.195M - The decrease is due to decreased estimates for Agency equipment purchases in FY 2025. Originally, migrations were scheduled to be concluding in FY 2025 so DISA would be tapering DAFA equipment purchases. Under the rebaselined schedule, DISA is conducting site survey on multiple DAFAs in FY 2025, purchasing the equipment it can afford to purchase, and planning to allocate additional FY 2026 funds to DAFA equipment purchases. FY 2026: $75.386M: DoDNet Equipment/Agency Migration Support: Many DAFAs do not have DoDNet compliant infrastructure. The DoDNet PMO must conduct a Tech refresh for the DoDNet migration to occur. The DoDNet PMO conducts site surveys to determine the level of tech refresh required at each agency. Costs associated with tech refresh and replacement vary due to the size of the DAFA and the quality of the current equipment. FY 2026 will include the following activities: • Acquire network infrastructure hardware (HW) to upgrade/tech refresh outdated equipment at multiple DAFA site locations. Modernized infrastructure is determined by the number of DAFA sites, site size, cabling/integration, design, and install of all-new network equipment. After deployment and integration, this effort will consolidate multiple networks into a single, centrally managed network. Tech refresh of outdated, end-of-life equipment and provide enhancements to standardize network infrastructure, improve network cybersecurity, and strengthen network resilience across the DoDNet environment. Hardware will also support network monitoring capabilities critical for network discovery and service performance. These capabilities help to identify and mitigate service issues quickly. Deployment of hardware, software, and network monitoring capabilities will provide the ability to adjust to changes in DoD/Agency priorities and needs. These tools will also reduce the growth of redundant IT systems and increase the visibility of all network-connected devices. • Procured hardware will replace outdated equipment with updated tools that can be integrated into the DoDNet environment. DoDNet PMO will have a total of 11 active migrations in FY 2026. 83,062 NIPR/SIPR users are planned to migrate to DoDNet. DoDNet PMO will purchase network hardware and software to migrate Agencies to DoDNet securely and safely. • Install and integrate hardware. With the FY 2026 increase in procurement, DISA will install and integrate procured hardware at the DAFAs using procurement funding. Life Cycle Refresh for Migrated Agencies: DAFAs require lifecycle technical replacements to keep the networks operating effectively and securely after successful migration. Replacements are expected to begin in FY 2025 on equipment purchased to support the initial migrations. Conduct lifecycle technical refresh of agencies already migrated to DoDNet after four years. The DoDNet is on a five-year equipment replacement lifecycle that will start four years after the equipment is purchased. Replacements of equipment will continue in FY 2026 for the first three DAFAs already migrated to DoDNet (DISA, DPAA, and DTIC) to complete their tech refresh to 100% by the 5-year lifecycle replacement mark. Explanation of Change from FY 2025 to FY 2026: $50.904M - The increase is to implement a new migration strategy of DoD funding DAFA migration costs up front. Asking DAFAs to self-fund migration causes schedule delays, so DoD is putting forward the funding for hardware procurement, installation and integration. Previously, DoD only contributed a portion of the funding, which caused DAFAs to delay migration. In FY 2026, DISA plans to focus on equipment purchase and user migration. FY 2026 will be a pivotal year in which DISA will migrate more than 80,000 users to DoDNet and make significant infrastructure upgrades to support ongoing migrations. DISA is making a substantial investment to ensure that DAFAs have the resources to migrate. Increase includes support for the Joint Service Provider (JSP) migration: DISA will now be migrating 65,000 JSP users as well the commodity IT planned for in the FY 2025 PB. Performance Metrics: 1. Number of new (NIPR and SIPR) users migrated to DoD Net. FY 2024: 52,941 Planned out of 111,146 total users / actual 0 users. Note: DISA completed user account migration in FY 2023 but continued migrating additional endpoints in FY 2024. Some users who already had DoDNet account received the devices to regularly use DoDNet in FY 2024. FY 2025: 57,038 Planned out of 172,470 total users FY 2026: 83,062 Planned out of 172,470 total users Note: The number of users represents most recent reports from DAFAs and JSP users and is higher from prior estimates. 2. Number of Active Agency Migrations. FY 2024: 11 Planned / 8 actual; Note: DISA was unable to initiate all planned migrations in FY 2024 due to delays entering into MOAs with customers. Due to issues with customer funded migrations, DISA developed a new DoDNet migration strategy that involves directly funding migrations and migrating end points prior to network IT. FY 2025: 11 Planned FY 2026: 11 Planned Note: Active migrations ongoing / overlapping across multiple fiscal years. Migration activities include site surveys, planning and design, installation / integration (replacement of outdated equipment / migration of users to DoDNet).
