The Quantum Clock is Ticking: Why Your Business Needs Post-Quantum Cryptography Before It’s Too Late
The cybersecurity landscape is about to face its biggest disruption in decades. While quantum computers capable of breaking current encryption don’t exist today, data that is currently not quantum-safe may be compromised in the future by quantum computers through “harvest now, decrypt later” attacks. This means cybercriminals are already collecting encrypted data today, waiting for quantum computers powerful enough to decrypt it tomorrow.
For businesses in Contra Costa County and beyond, the time to act is now. Some experts predict that a device with the capability to break current encryption methods could appear within a decade, making post-quantum cryptography (PQC) implementation not just a future consideration, but an urgent business priority.
Understanding the Quantum Threat
Post-quantum cryptography is the development of cryptographic algorithms that are currently thought to be secure against attacks by quantum computers. Most widely used public-key algorithms rely on mathematical problems that could be easily solved on a sufficiently powerful quantum computer running Shor’s algorithm.
The threat extends beyond theoretical concerns. The average cyberattack costs a small business $200,000, including recovery costs, lost productivity, legal fees, and regulatory fines. Sixty percent of small companies go out of business within six months of a cyber attack. When quantum computers arrive, businesses relying on outdated encryption will face exponentially higher risks.
NIST Standards: Your Roadmap to Quantum Safety
The National Institute of Standards and Technology (NIST) has provided the cybersecurity community with a clear path forward. In August 2024, NIST finalized its principal set of encryption algorithms designed to withstand cyberattacks from quantum computers, releasing three Federal Information Processing Standards (FIPS).
The three standardized algorithms are:
- ML-KEM (FIPS 203): Module-Lattice-Based Key-Encapsulation Mechanism, based on the CRYSTALS-Kyber algorithm, intended as the primary standard for general encryption
- ML-DSA (FIPS 204): Module-Lattice-Based Digital Signature Algorithm, derived from CRYSTALS-Dilithium, intended as the primary standard for protecting digital signatures
- SLH-DSA (FIPS 205): Stateless Hash-Based Digital Signature Standard, providing conservative hash-based security
NIST expects that these standards will provide the foundation for most deployments of post-quantum cryptography and can be put into use now.
Implementation Challenges and Solutions
Transitioning to post-quantum cryptography isn’t as simple as flipping a switch. A challenge in post-quantum cryptography is the implementation of potentially quantum safe algorithms into existing systems. Organizations face several hurdles:
Legacy System Integration: The replacement of current cryptographic standards with new post-quantum standards presents significant technical challenges due to worldwide interconnectedness and established protocols. Many businesses operate on systems that weren’t designed with crypto-agility in mind.
Performance Considerations: Post-quantum algorithms typically require larger key sizes and more computational resources than current encryption methods. This can impact system performance, particularly in resource-constrained environments.
Compliance and Timeline Pressures: Under the transition timeline in NIST IR 8547, NIST will deprecate and ultimately remove quantum-vulnerable algorithms from its standards by 2035, with high-risk systems transitioning much earlier.
Strategic Implementation Approach
Smart businesses are adopting a phased approach to PQC implementation. Organizations should start testing ML-KEM and ML-DSA in hybrid deployments, as hybrid combinations like ML-KEM + X25519 or ML-DSA with fallback can help validate early compatibility.
The key steps include:
- Cryptographic Discovery: Using cryptographic inventory tools to learn where and how cryptography is being used to protect the confidentiality and integrity of your organization’s important data and digital systems, supporting risk management and prioritization decisions
- Risk Assessment: Identifying which systems handle the most sensitive data and require immediate protection
- Pilot Implementation: Testing post-quantum algorithms in controlled environments before full deployment
- Gradual Migration: Systematically replacing vulnerable algorithms across your infrastructure

Their team understands that every industry faces unique cybersecurity challenges and regulatory requirements that generic solutions can’t address, which is why industry expertise matters when choosing cybersecurity protection.
The Cost of Waiting
While the quantum threat may seem distant, the preparation timeline is compressed. Purchasing post-quantum encryption solutions available on the market today without NIST approval could prove costly and create a more challenging transition to approved standards. However, waiting too long poses even greater risks.
Even though large, code-breaking quantum computers are not here yet, adversaries can harvest now and decrypt later. Moving to NIST-approved PQC reduces that risk. The businesses that begin their quantum-safe transition now will have a significant competitive advantage over those that wait.
Taking Action Today
Post-quantum cryptography implementation represents one of the most significant cybersecurity transitions in modern business history. NIST’s publication of the PQC standards is not an endpoint but rather the beginning of the quantum-safe journey. Adopting a systematic approach with crypto-agility will enable organizations to execute a quantum-safe migration.
The quantum revolution is coming whether businesses are ready or not. Organizations that begin implementing post-quantum cryptography today will protect themselves against future threats while positioning themselves as security leaders in their industries. Those that wait risk becoming victims of the very technology that promises to transform our digital world.
Don’t let your business become a casualty of the quantum revolution. Start your post-quantum cryptography journey today, and ensure your data remains secure in the quantum age.
