[Mumken PQC Platform](https://cybersectools.com/tools/mumken-pqc-platform) Mumken is a company homepage presenting a suite of post-quantum cryptography and digital sovereignty solutions for governments and enterprises. The offerings are organized around three missions: protecting information, protecting borders, and protecting identity. For protecting information, Mumken provides a post-quantum cryptographic engine that combines classical and post-quantum algorithms, offering crypto-agility so organizations can change algorithms without redesigning systems. This engine underpins additional products: quantum-resistant encrypted communication tunnels for interconnecting networks, sites, and data centers, and a proxy that adds a post-quantum protection layer in front of existing services without requiring changes to those applications. For protecting borders, Mumken offers automated border-control posts combining biometrics, document verification, and configurable rules, along with a central management platform that coordinates border posts, biometric systems, and passenger flows with dashboards and alerting. For protecting identity, the company provides a document and identity verification platform aimed at reducing fraud, a platform for secure issuance of identity and travel documents compliant with ICAO 9303 using cryptographic chips, and a platform for issuing high-density QR codes with cryptographic verification, optionally integrable with facial biometrics. The page addresses the "harvest now, decrypt later" threat from quantum algorithms such as Shor and Grover, which threaten RSA, ECC, AES, and SHA-2 based systems, and references NIST PQC, ENISA, and ETSI standards. Target sectors mentioned include public administration, security, defence, critical infrastructures, banking and finance, fintech, healthcare, telecommunications, and industry.
