Market Dynamics

Growth Drivers: Growing threat of quantum attacks on conventional encryption is accelerating demand for quantum-safe network infrastructure globally

The increasing risk that future quantum computers could compromise widely used public-key cryptographic systems is significantly driving demand for quantum-safe network infrastructure. he quantum-safe technology is created to ensure safety of communication and confidential data not only from classical but quantum-powered attacks as well. The problem of "harvest now, decrypt later" attack is especially pushing organizations to secure their sensitive information before quantum-powered computers become accessible for cryptographic computations. NIST encourages organizations to start implementing post-quantum cryptography right now and has developed ML-KEM, ML-DSA and SLH-DSA standards. It is encouraging enterprises, governmental organizations, telecommunications companies, banks, and other critical infrastructure to upgrade their network architecture by using quantum-resistant cryptography and key management systems.

Restraints: High migration costs and complex legacy infrastructure can limit adoption of quantum-safe network technologies

High migration costs remain a significant restraint for organizations transitioning from conventional cryptography to quantum-resistant network infrastructure. Businesses commonly have many legacy systems that include applications, networking components, certificates, protocols, and cryptography which were not built with quantum-resistant mechanisms in mind. It can cost a lot of money to detect vulnerable cryptography elements and then replace or upgrade them. The NIST migration guidance stresses the importance of developing an exhaustive inventory of the existing cryptography and prioritizing the vulnerable elements during the transition. As a result, a migration process can take a lot of time and be rather costly, especially for those businesses that have a complex distributed network structure.

Opportunities: Accelerating enterprise migration to post-quantum cryptography creates significant opportunities for quantum-safe network infrastructure providers globally

The transition toward standardized post-quantum cryptography is creating substantial opportunities for network security vendors. Organizations require tools that can help to detect vulnerable cryptographic assets, adopt quantum-resistant cryptography, manage certificates and keys, and ensure secure communications. The final NIST standards provide an excellent basis for such a migration, while the institute continues its research to develop tools for migration, testing, benchmarking, and interoperability. There are many possibilities for vendors to use PQC technology in their TLS, VPN, IPsec, gateways, routers, switches, firewalls, network management systems, and enterprise security solutions. Another area of opportunity is crypto-agility that helps to quickly update cryptographic algorithms based on new standards.
