The Coming Wave: Post-Quantum Cryptography and the Future of Cybersecurity

Quantum computing represents an existential threat to traditional encryption. Cryptographic standards like RSA and ECC, which form the backbone of digital security, were never built to withstand quantum-level computation. Once quantum machines reach scale, they’ll be able to break them in minutes.

Post-Quantum Cryptography (PQC) offers a drop-in, scalable alternative built to survive the quantum era. Unlike theoretical solutions like quantum key distribution (QKD), PQC is grounded in challenging mathematical problems resistant to quantum attacks, making it the most viable path forward for securing modern infrastructure.

The urgency to adopt PQC is intensifying as "harvest now, decrypt later" threats become more plausible. Adversaries are already collecting encrypted data today, betting they’ll be able to crack it once quantum computers mature, turning delayed action into a future data breach.

Incumbent security vendors and hyperscalers are gearing up for the shift, but few have announced definitive roadmaps. Companies like Palo Alto Networks and CrowdStrike are likely preparing PQC integrations behind the scenes, while NIST and NSA are actively shaping standards that will govern global adoption.
