Challenges for enterprises: The NCSC’s roadmap underscores the urgency of transitioning to PQC, but businesses may face significant challenges in meeting the proposed timelines.The migration process could be complex, costly, and disruptive, requiring organizations to overhaul encryption protocols embedded in critical infrastructure, financial systems, and cloud services.Kawoosa pointed out that while enterprises typically have basic cybersecurity measures in place, only certain industries such as banking and financial services have invested in more advanced protections.”In general, cybersecurity is only given serious attention when something happens,” Kawoosa added.This reactive approach could pose risks as quantum threats grow more imminent. Waiting too long to begin migration could leave critical systems vulnerable to emerging threats.However, on the plus side, both quantum computing and PQC are still in the early stages of development.”I think we are still in the infancy stage when it comes to quantum computing in action,” Kawoosa said. “The same applies to post-quantum cryptography. We have to bear in mind that NIST only established standards for it in 2024, so the actual work on developing solutions is just beginning.”
