Quantum Sentinel Limited notes that the United States Executive Order 14412 requires federal high-value assets and high-impact systems to use post-quantum key establishment by the end of 2030 and post-quantum signatures by the end of 2031.

Quantum Sentinel is the Enterprise Cryptographic Exposure Management (ECEM) platform that helps organisations discover enterprise cryptography, understand cryptographic exposure, and confidently prepare for the transition to post-quantum cryptography (PQC). While most organisations understand their cyber vulnerabilities, very few understand their cryptographic exposure. Quantum Sentinel bridges that gap by combining Enterprise PQC Discovery, cryptographic inventory, exposure assessment, and migration planning into a single platform. Our agentless, on-premises platform provides read-only discovery across enterprise environments to build a comprehensive cryptographic inventory (Enterprise CBOM), assess cryptographic exposure, prioritise migration efforts, and deliver actionable intelligence for security teams and executives. Built by cybersecurity practitioners with more than 23 years of enterprise security experience, Quantum Sentinel was created to help organisations move beyond cryptographic discovery and turn visibility into confident business decisions. Our Focus: • Enterprise Cryptographic Exposure Management (ECEM) • Enterprise PQC Discovery • Cryptographic Discovery & Inventory • Enterprise CBOM • Cryptographic Exposure Assessment • Quantum Readiness • PQC Migration Planning • Cryptographic Risk Intelligence Know Your Cryptographic Exposure.
