Private Machines ENFORCER is a physical secure server platform certified to NIST FIPS 140-2 Level 4 standards. Originally developed for US Department of Defense and Department of Homeland Security applications, it is also available for commercial use. The ENFORCER SRX1 is the core server unit, incorporating multiple ENFORCER R1 tamper-proof compute blades. Each R1 blade functions as both a high-performance compute engine and a cryptographic Hardware Security Module (HSM) built to FIPS 140-2 Level 4 specifications. Key security properties include: - Physical and logical protection of all running computation and data - Access controls that prevent unauthorized parties — including insiders and administrators — from accessing data or computation, even under physical compulsion - Remote attestation capabilities that allow dynamic, remote verification of hardware, firmware, and software stack integrity - Anti-tamper defenses with support for remote zeroization or physical self-destruction of the module The platform is designed to address security gaps in conventional commercial infrastructure, including supply chain vulnerabilities, lack of confidentiality controls, code integrity risks, and physical access threats. ENFORCER is intended for deployment across data centers, private/public/hybrid cloud environments, edge locations, and specialized sectors including oil/gas, smart grid, payment networks, avionics, and defense/intelligence. The system runs standard x86 operating systems and software within its secure computation environment and is described as price-competitive with standard enterprise server hardware.
