Quantum Security Spending Set to Exceed 5% of IT Budgets by 2026

Last Updated: November 17, 2025By

Shifting IT Budgets Towards Quantum Security

With quantum computing on the horizon, companies are increasingly turning their attention—and funds—toward post-quantum cybersecurity measures. A recent Forrester report points to a significant trend: investments in quantum security could make up more than 5% of total IT budgets by 2026. But why the urgency? Quantum computers are expected to potentially crack current encryption standards within a decade, prompting swift action.

The U.S. National Institute of Standards and Technology (NIST) isn’t waiting for this eventuality. It has already laid out plans to phase out certain cryptographic methods like RSA and ECC, starting as early as 2030, with a full ban by 2035. In response, companies are re-assessing their cryptographic frameworks and leaning more on consultants to craft robust post-quantum strategies.

Building a Quantum-Ready Future

As we look to the future, it’s not just banking and defense sectors that need to prioritize quantum security—it’s becoming crucial for businesses of all stripes. For Chief Information Security Officers (CISOs), this means taking proactive steps to safeguard data, assets, and the all-important digital credibility.

As organizations reevaluate their cryptographic libraries and vendor relationships, they’re also eyeing cryptographic discovery tools and agile solutions with increased interest. Procurement and risk management professionals are on the front lines, tasked with ensuring their partners’ readiness for the quantum leap and adherence to new compliance standards.

The time to prioritize quantum security is now, and it seems everyone’s getting on board to ensure a seamless transition into a secure, quantum-ready world.
