Project Sentinel, identified under solicitation number 26-A008, is a Department of the Navy initiative led by NIWC Atlantic to develop and validate an enterprise-grade software capability that enforces Two-Person Integrity with Multi-Factor Authentication in disconnected, high-threat tactical environments. The solution must enable concurrent, hardware-validated dual-operator authorization for privileged actions—such as data deletion, privilege escalation, and network configuration changes—without reliance on cellular or internet connectivity. It must operate across heterogeneous systems including Windows and Linux operating systems, VMware vSphere, and Hyper-V hypervisors, using only dedicated physical cryptographic tokens or smart cards, explicitly excluding mobile devices. The prototype must demonstrate a 100% enforcement rate of dual approval under simulated disconnected conditions, with zero dependency on commercial networks, and must provide full documentation of compatibility across all specified platforms, including legacy and modern versions. The solicitation requires a detailed specification of the required physical hardware components and supported OS and hypervisor versions to ensure long-term maintainability and integration within Joint Force operational networks. The response deadline is August 13, 2026, and the contract falls under NAICS code 541715 with no set-aside classification. Primary point of contact is Jessie Rehwoldt at NIWC Atlantic in North Charleston, South Carolina.

Full Description

In highly contested Joint All-Domain Command and Control (JADC2) environments, tactical systems cannot rely on external network reach-back or cellular signatures for authentication. Project Sentinel will validate an enterprise-grade software capability that enforces concurrent, hardware-validated dual-operator controls locally—ensuring that critical, single-point-of-failure actions cannot be executed single-handedly in disconnected space.


The Department of the Navy requires a prototype to demonstrate and validate an enterprise-level software capability for Two-Person Integrity (TPI) combined with Multi-Factor Authentication (MFA) for Privileged Access Management (PAM) within highly isolated, disconnected, and heterogeneous operational networks across Joint Force environments. We seek to prototype and scale a unified, non-cellular-reliant dual-authorization mechanisms to safeguard privileged functions—such as critical data deletion, privilege escalation, and network configuration changes—across diverse target systems (Windows, Linux, hypervisors, and network hardware). This effort seeks to evaluate a minimum viable product that enforces concurrent dual-operator authentication using dedicated physical hardware components (such as physical cryptographic tokens or smart cards, excluding mobile devices) in disconnected environments, ensuring critical system changes cannot be executed single-handedly. To ensure long-term supportability and integration, the technical response must explicitly define the physical hardware components required to support the solution, as well as the specific operating system and hypervisor versions supported (including legacy and modern Windows, Linux, VMware/vSphere, and Hyper-V distributions). Success will be measured by a 100% enforcement rate of concurrent, multi-factor dual-approvals under simulated disconnected-state operations, zero dependency on commercial cellular/internet networks, and documented cross-platform compatibility across all specified target systems.
