What should you look for in the PQC Advisory or Support Service? 

It is no longer breaking news that the National Institute of Standards and Technology (NIST) has officially selected five post-quantum cryptographic algorithms, a long-anticipated move that marks a crucial step in the cryptographic shift toward quantum resilience. Additionally, NIST has also made it clear that by 2030, widely used algorithms such as RSA, Elliptic Curve Diffie-Hellman (ECDH), MQV, Finite Field DH, ECDSA, and EdDSA (at 112-bit security strength) will be deprecated. 

Let us quickly recap the five algorithms selected by NIST:  

Current Specification Name	Initial Specification Name	FIPS Name	Parameter Sets	Type
ML-KEM-1024	CRYSTALS – Kyber	FIPS 203	Kyber512 Kyber768 Kyber1024	Lattice-Based Cryptography
ML-DSA-87	CRYSTALS – Dilithium	FIPS 204	Dilithium2 Dilithium3 Dilithium5	Lattice-Based Cryptography
SLH-DSA	SPHINCS+	FIPS 205	SPHINCS+ – 128s SPHINCS+ – 192s SPHINCS+ – 256s	Hash-Based Cryptography
FN-DSA	FALCON	FIPS 206	Falcon – 512 Falcon – 1024	Lattice-Based Cryptography
HQC	HQC (Hamming Quasi–Cyclic)	Pending Standardization	HQC – 128 HQC – 192 HQC – 256	Code-Based Cryptography

So, what does this mean for us? In simple terms, by adopting these algorithms, we are not just preparing for the future, we are building a security net before quantum computers become a real-world threat.  

While quantum computers are still in the developmental phase, experts agree that it is only a matter of time before they become powerful enough to break today’s encryption. What’s even more concerning is that attackers are not sitting idle. They are already capturing encrypted data today and storing it until quantum technology is advanced enough to decrypt it. This approach, known as “harvest now, decrypt later,” poses a growing threat to governments, enterprises, and anyone handling sensitive information. 

The impact, however, extends far beyond that. Quantum attacks could also break the PKI systems used to issue digital certificates, shaking the foundation of trust in secure communication, email security, and online transactions. Without crypto agility, replacing vulnerable algorithms will require major system overhauls, causing operational downtime, compatibility issues, and high costs. There is also the risk of forged digital signatures, allowing attackers to impersonate trusted identities. And perhaps most critically, traditional encryption algorithms like RSA and ECC will no longer be able to protect data, making confidential information vulnerable to decryption by quantum computers. 

So, what is the risk of waiting? Delaying the transition to quantum-safe cryptography could leave sensitive data such as PHI, PII, and PCI exposed in the years to come. That is why governments, financial institutions, and tech giants have already begun working with PQC advisory partners to assess risks, plan migrations, and integrate quantum-safe strategies into their critical infrastructure and supply chains. 

The time to act is now. But making the shift to post-quantum cryptography (PQC) is not just about urgency, it is about doing it right. Organizations need guidance from experts who understand the complexities of cryptographic environments. Specialized PQC advisory services can help assess existing systems, identify potential risks, and design a smooth, secure roadmap for adopting quantum-safe algorithms.  

Why Do You Need a PQC Advisory or Support Service? 

Making the shift to PQC requires understanding what is at risk, auditing existing cryptographic systems, identifying where vulnerable algorithms are used, and planning how to migrate the legacy infrastructure without causing service disruptions. That involves updating protocols, keeping systems compatible, and making sure everything continues to run smoothly during the shift. Therefore, organizations need dedicated PQC advisory services to carry out comprehensive assessments, develop customized strategies, and build a phased roadmap that supports a secure and efficient migration to quantum-safe cryptography. 

Here is why having a PQC advisory or support team by your side makes all the difference: 

• Comprehensive Risk Assessment is Needed

  Before you can start planning a migration, you need to understand where your systems are most vulnerable to quantum threats. This begins with a thorough risk assessment to identify vulnerabilities, outdated algorithms, weak cryptographic implementations, and potential gaps that quantum computers could exploit. The insights from this analysis help you focus on the most critical areas first and allocate your resources efficiently for a smooth and secure transition.

• One-Size-Fits-All Strategies Don’t Work

  Every organization has its own infrastructure, risk profile, and business priorities. Relying on a generic migration plan can lead to inefficiencies or leave important assets unprotected. That is why it is important to assess your specific environment and build a customized PQC roadmap. A tailored approach ensures you strike the right balance between your operational needs and long-term security goals.

• PQC Migration Is Complex

  Migrating to PQC is not just another technical upgrade, it is a structural change across your entire cryptographic infrastructure. Everything from key exchange mechanisms and digital signatures to internal APIs and protocol layers needs to be reviewed and updated for quantum resilience. On top of that, securely migrating existing cryptographic keys and assets adds another layer of complexity. To make this process more manageable, a systematic approach is needed, one that helps identify risks, prioritize changes, and enable cryptographic agility without disrupting existing operations.

• Specialized Expertise Is Essential

  Specialized expertise is essential when it comes to post-quantum cryptography. With new algorithms, evolving standards, and complex implementation challenges, navigating this shift requires deep, up-to-date knowledge. Rather than expecting internal teams to master this rapidly changing space, it makes sense to rely on PQC experts who bring the latest knowledge of PQC algorithms, NIST recommendations, performance trade-offs, industry best practices, and deployment strategies.

• Ongoing Support and Compliance Alignment Matters

  Quantum readiness is the ability of an organization to prepare for and adapt to the security challenges posed by quantum computing. It is not a one-time project, but a continuous journey that requires long-term attention and strategic oversight. Without expert guidance, organizations risk falling out of compliance or overlooking critical updates. Long-term advisory support ensures your cryptographic systems evolve with the latest standards, your teams stay informed through training, and your organization stays aligned with a proactive, future-proof, quantum-safe approach.

These are just a few reasons why PQC advisory and support service really matters. The right partner can help you stay ahead of quantum threats without disrupting your current operations.

But with so many options out there, the bigger question is, how do you choose the right services for quantum readiness and impact assessments?

Key Qualities of a Trusted PQC Advisory Partner 

Now that you know why expert help matters, let us explore what to look for when choosing your PQC advisory partner. Here are the key factors to keep in mind when evaluating a Post-Quantum Cryptography (PQC) service provider: 

• Proven Cryptographic Expertise

  Choosing the right services for quantum readiness means working with experts who bring deep knowledge of both classical and post-quantum cryptography. It is essential that they closely follow NIST’s standardization process and understand how each candidate algorithm performs under real-world conditions. Just as importantly, they should be able to evaluate the strengths and trade-offs of each post-quantum approach and align those insights with your specific use cases, system architecture, and performance requirements.

• Experience with Legacy-to-PQC Migrations

  Successful quantum readiness requires experience, particularly in migrating legacy systems. Legacy environments often use outdated protocols and hardcoded cryptographic libraries, making them difficult to upgrade without disrupting operations. These systems were never designed to mitigate quantum threats or even to support crypto agility, which makes upgrades even more difficult. That is why it is critical to work with advisors who can assess your existing cryptographic environment and seamlessly integrate quantum-safe algorithms, all while ensuring minimal disruption and maintaining operational continuity.

• Support for Algorithm Suitability and Cryptographic Agility

  Not all quantum-resistant algorithms are designed to perform equally across different cryptographic environments. That is why it is important to evaluate them based on your specific needs, whether that’s performance, device constraints, or bandwidth limitations.

  For instance, ML-DSA is used for digital signatures. It is all about making sure that the data remains unchanged and authentic. On the other hand, ML-KEM is used for key exchange, much like RSA or Diffie-Hellman, and is perfect for protecting data confidentiality as it moves across networks.

  Also, make sure your partner values cryptographic agility, which is the ability to adapt to new algorithms as standards mature or new threats arise. Any advisory team you engage should prioritize this flexibility, ensuring your systems remain secure and future-ready as quantum technology continues to advance.

• Comprehensive Risk Assessment and Strategy Development

  Effective quantum readiness begins with visibility. You need a partner who can audit your existing cryptographic assets, identifying what is vulnerable, what is urgent, and what can be addressed over time. This begins with creating a clear cryptographic inventory that shows where and how encryption is used across your systems. From there, the advisory team should perform a quantum risk impact analysis to understand which systems are most exposed. A strong partner will go beyond surface-level scans and help you build a crypto-agility profile and a quantum risk heatmap, giving you a clear picture of your overall risk and preparedness.

  Remember, PQC migration is not just about replacing algorithms. It is about understanding your organization’s unique cryptographic environment and executing a focused, strategic plan. The right team will help you carry out a comprehensive risk assessment, define a prioritized action plan, and develop a phased migration and mitigation strategy customized to your needs. They will also support pilot testing, ensure smooth implementation, and keep your systems updated as new standards and threats emerge.

• Integration and Migration Support

  Implementing post-quantum cryptography is not a one-size-fits-all process, especially when your infrastructure spans cloud, on-premises, and hybrid environments. You need a team that can navigate this complexity step by step, starting with pilot tests in controlled environments to identify and resolve issues early. After that, they should be able to smoothly integrate PQC into a production environment. This includes managing cryptographic keys, protocols, and infrastructure across all platforms while making sure the transition to quantum-safe cryptography is smooth, secure, and resilient.

• Ensure Backward Compatibility

  Transitioning to post-quantum cryptography is not about ripping out existing systems, it is about enabling coexistence. To ensure backward compatibility with legacy infrastructure, it is essential to adopt hybrid deployments that combine classical algorithms (like RSA or ECC) with post-quantum algorithms (such as Kyber). An experienced partner should be able to seamlessly integrate these hybrid cryptographic models into existing legacy systems, APIs, TLS stacks, and mobile environments while balancing performance, interoperability, and security.

• Ongoing Monitoring and Support

  Quantum threats are not static, and neither are the standards meant to fight them. You need continual updates, algorithm replacements, and regular security monitoring to stay protected. So, look for a partner that offers long-term support, timely threat intelligence, and the flexibility to adapt your cryptographic posture as new standards and risks evolve.

• Cost-Effectiveness and Value

  Security is non-negotiable but so is staying within budget. That is why it is important to work with a partner who delivers cost-efficient solutions without compromising cryptographic strength. The right team will help you maximize the value of your investment, delivering quantum-resistant protection without overengineering or overspending.

Choosing the right PQC partner is not just about checking boxes. It is about building a trusted relationship with a team that understands the bigger picture and offers hands-on support. PQC is a journey, and the sooner you start with the right support, the smoother and more cost-effective your path to quantum safety will be.
