Why Cryptographic Discovery Matters for Post-Quantum Security

The success of post-quantum migration hinges on creating comprehensive inventories of cryptographic systems across an organization's infrastructure. However, this task is complicated by the presence of embedded systems, hardware encryption, legacy infrastructure, and third-party dependencies, making it difficult for organizations to accurately identify and track quantum-vulnerable cryptographic assets. Regulatory guidance from prominent agencies such as CISA, NIST, and NSA is increasing the pressure to address this issue¹. The discovery of existing cryptographic systems is crucial for a seamless migration to post-quantum cryptography. As quantum computing developments advance, the timeline for cryptographic migration is narrowing, emphasizing the need for urgent planning. The NSA's recent quantum developments have further accelerated the need for post-quantum cryptography planning, making it essential for practitioners to prioritize cryptographic inventory and migration to ensure the long-term security of their systems. This matters because failing to do so may leave organizations vulnerable to quantum-powered attacks.
