What the post-quantum executive order really demands of CISOs

The executive order on post-quantum cryptography (PQC) establishes deadlines for federal systems to transition to PQC by 2030 for key establishment and 2031 for digital signatures. It emphasizes urgency due to 'Harvest Now, Decrypt Later' attacks, where adversaries collect encrypted data for future decryption via quantum computing. CISOs must shift from awareness to structured ownership, involving cross-functional teams to address embedded cryptographic risks across enterprises.
