Every organization relies on encryption to protect its most valuable data. However, quantum computing is advancing quickly, creating new risks that traditional methods can’t withstand. Post-quantum encryption offers a path forward. In this piece, you’ll learn what it is, why it matters now, and the practical steps you can take to start preparing with confidence.
Every time you send an email, log into a bank account, or connect to a website, encryption protects your information. These tools have worked for decades, but quantum computing is changing the equation. Around the world, researchers are advancing machines powerful enough to break today’s most trusted security methods in seconds. Yesterday’s encryption won’t withstand tomorrow’s threats. Post-quantum encryption offers a way forward, but only for organizations that prepare now.
Every organization depends on encryption to protect what matters most — from patient health records to trade secrets and government data. Encryption locks this information behind mathematical puzzles that are nearly impossible for classical computers to solve.
Two of the most common systems in use today are RSA and ECC. These are different types of cryptography that have safeguarded sensitive data for decades. With current technology, breaking their codes would take centuries, which is why they’ve been considered secure.
Quantum computing changes that assumption. By applying the principles of quantum physics, these machines can solve in seconds what would take classical computers billions of years. That means RSA and ECC, once trusted for decades, could fail almost instantly.
Post-quantum encryption (PQE) is designed for this new age. It uses algorithms resistant to quantum-powered attacks, ensuring that sensitive information remains protected even as quantum breakthroughs accelerate. For leaders, preparing for PQE is less about technology alone and more about safeguarding the trust your organization relies on.
Quantum computing represents a seismic shift in computational power. Unlike classical machines, which rely on brute force to break encryption, quantum systems use principles like superposition and entanglement to solve problems exponentially faster. And, the result is simple, encryption methods that were trusted for decades are no longer future-proof.
Here’s why current security may be at risk:
For business leaders, the risk is no longer theoretical. Technology is advancing quickly, and attackers are already preparing. Acting early gives your organization more options and great resilience than waiting until the threat arrives.
Recognizing the risks of quantum computing, governments are already setting expectations for how encryption must evolve.
On June 23, 2025, the Government of Canada released its official roadmap for migrating federal systems to post-quantum encryption. The milestones include:
These deadlines are already influencing how public institutions prepare for the shift. Many are realizing that early preparation is the best way to meet complex, multi-year requirements.
In the U.S., the National Institute of Standards and Technology (NIST) is keeping pace with post-quantum encryption. In March 2025, it was confirmed that today’s common methods such as RSA and ECC, will eventually be retired. In their place, NIST has identified new quantum-safe options such as ML-KEM (also called Kyber) and ML-DSA (also called Dilithium).
Preparing for the quantum era isn’t a quick software update. It requires planning, awareness, and commitment across every part of the organization. Leaders who start early will find the transitions more manageable and protect their organizations from both compliance gaps ad reputational risks.
Here are essential steps to consider:
Begin by identifying where and how encryption is used across your systems, applications, and data flows. Many organizations lack a full picture, especially when shadow IT or older integrations are involved. Without this map, planning a transition is almost impossible.
Not all data carries the same level of risk. Long-lived records, such as health information, financial data, and intellectual property, are prime targets for harvest now, decrypt later attacks. Understanding which assets are most vulnerable allows leaders to prioritize resources effectively.
Moving from classical encryption to quantum-safe algorithms can take years. Break the work into phases so systems can be updated in an orderly way. A roadmap helps avoid last-minute scrambles when new standards take effect.
Leadership often underestimates the pace of quantum progress. Training executives, IT staff, and compliance teams builds awareness and ensures decision-makers understand what’s at stake. Education is also key to overcoming misconceptions, such as assuming vendors will solve the problem alone.
Regulations and cryptographic standards are changing at a steady pace, and organizations need a way to keep up. A quantum risk function is a dedicated process for tracking new developments, assessing vendor claims, and reviewing contractual obligations. Building this discipline ensures your organization can adapt to updates as they happen, rather than of reacting when it’s already too late.
Even with careful planning, several obstacles can delay or complicate progress toward quantum readiness. Recognizing these challenges early is key to building a resilient strategy.
Preparing for quantum computing takes steady progress over time. It involves technology, people, and strategy working together toward the same goal. The journey will look different for every organization, yet the risk is highest for those holding sensitive data such as customer information, financial records, or intellectual property. With experienced guidance, even complex changes can be broken into manageable steps.
The following examples show how a specialized organization can support the process and make readiness more achievable:
Quantum computing will transform cyber security in ways that are only beginning to be understood. Organizations that start preparing now will have more control over the transition and greater confidence in the protection of their most valuable data.
Whether the first step is understanding current readiness, mapping encryption across systems, or planning a migration to quantum-safe algorithms, progress made today reduces risk tomorrow. With expert guidance and steady action, even the most complex challenges can be managed. The result is resilience — a future-ready security posture built to protect both information and trust in the years ahead.
