Private Machines Inc. is a hardware security company that designs and manufactures high-performance Hardware Security Modules (HSMs). Their flagship product, the ENFORCER R2, is engineered to meet NIST FIPS 140-3 Level 4 certification — the highest level of physical and logical security defined by that standard. Unlike traditional HSMs, which are typically limited to cryptographic operations, the ENFORCER is designed with general-purpose x86 processing capabilities. This allows it to run standard off-the-shelf x86 operating systems and applications entirely within its tamper-proof security boundary, effectively extending the security perimeter to encompass full workloads rather than just key management functions. The company also references a "CipherRack" product in its contact forms, suggesting a rack-level secure infrastructure offering alongside the ENFORCER appliance line. Their inquiry forms indicate support for deployments across major cloud providers including Amazon Web Services, Microsoft Azure, Google Cloud, DigitalOcean, and DreamHost, pointing to hybrid and multi-cloud use cases. Private Machines positions its technology under a Zero Trust infrastructure framework, targeting organizations that require strong hardware-rooted trust for sensitive computing workloads. The company operates under the broader Virtalica corporate entity, which handles company information, careers, and legal terms.
