  • •Compliance with new regulations like the EU Cyber Resilience Act is critical for affected sectors.

As quantum computing poses a significant threat to current cryptographic systems, organizations are urged to transition to post-quantum cryptography (PQC). Cisco's CNSA 2.0 blueprint aims to safeguard WAN infrastructures against harvest now, decrypt later (HNDL) attacks, with a full transition mandated by the NSA by 2031. The EU Cyber Resilience Act also introduces new reporting obligations starting September 2026, emphasizing the urgency for compliance. Traditional hardware root of trust (HRoT) systems are inadequate against quantum threats, necessitating a shift towards cryptographically agile solutions. Cisco's IOS XE software now integrates NIST-standardized algorithms like ML-KEM to enhance data protection in transit. Organizations in finance, healthcare, and utilities are particularly affected due to the long-term nature of their data confidentiality needs. The transition to quantum-safe systems is critical as the timeline for quantum threats accelerates.
