pQCee Arms Windows for the Quantum Era with New Security Tool

SINGAPORE – March 23, 2026 – As the world braces for the disruptive power of quantum computing, Singapore-based cybersecurity innovator pQCee today launched a critical new tool designed to protect the ubiquitous Microsoft Windows operating system from future threats. The company announced its crypto-agile Cryptographic Next Generation (CNG) provider, a solution engineered to help organizations navigate the complex and urgent transition to post-quantum security.

The software acts as a flexible bridge, allowing enterprises, governments, and regulated industries to integrate a wide array of next-generation encryption standards directly into their Windows environments, preparing them for an era where today's security protocols could become obsolete overnight.

The Race Against the Quantum Clock

The launch arrives at a pivotal moment in cybersecurity. The "quantum threat" is no longer a theoretical concern confined to academic papers. It refers to the immense power of future quantum computers, which are expected to utilize algorithms like Shor's algorithm to break the public-key encryption, such as RSA and ECC, that currently protects virtually all digital communications, financial transactions, and sensitive data.

While a "Cryptographically Relevant Quantum Computer" (CRQC) capable of this feat may still be several years away—with some estimates placing its arrival in the early to mid-2030s—the danger is immediate. Adversaries are already engaging in "harvest now, decrypt later" (HNDL) attacks, where they steal and store vast amounts of encrypted data today, confident they can unlock it once a powerful quantum computer becomes available. This makes any data requiring long-term confidentiality—from government secrets to intellectual property—vulnerable right now.

In response, government bodies have been racing to establish new safeguards. The U.S. National Institute of Standards and Technology (NIST) recently finalized its first set of post-quantum cryptography (PQC) standards, including ML-KEM, ML-DSA, and SLH-DSA. NIST has mandated a full transition to PQC by 2035, urging organizations to begin the complex, multi-year migration process immediately.

Crypto-Agility: A Flexible Defense for a Shifting Landscape

pQCee's solution is built on the principle of "crypto-agility," the capacity for a security system to be rapidly updated to handle new cryptographic algorithms and protocols without requiring a complete system overhaul. In a world of evolving standards and emerging threats, this flexibility is paramount.

“Crypto-agility is the cornerstone of post-quantum security,” said Dr. Teik Guan Tan, CEO of pQCee. “At pQCee, we’ve built our CNG provider to give organizations flexibility and confidence—whether they need to adopt global standards, meet national mandates, or integrate cutting-edge quantum technologies. Our mission is to make quantum-safe security practical, adaptable, and future-ready.”

By integrating with Microsoft's native Cryptography API: Next Generation (CNG) framework, the provider allows Windows applications to seamlessly use a variety of post-quantum algorithms. This includes not only the new NIST standards but also other algorithms like XMSS and LMS, as well as hybrid approaches that combine the proven strength of classical cryptography with the future-proof security of PQC. This allows for a phased, managed transition rather than a disruptive, all-at-once switch.

Bridging Global Standards and National Mandates

A key differentiator for pQCee's provider is its ability to look beyond the NIST standards and accommodate a growing patchwork of national cryptographic requirements. As nations seek to establish their own "cryptographic sovereignty," they are developing unique, country-specific PQC standards.

The pQCee tool explicitly supports these national mandates, including:
* Malaysia’s MySEAL: A national trusted algorithm list designed to support the country's National Cryptography Policy.
* South Korea’s KpqC: A set of nationally standardized algorithms, such as the HAETAE digital signature and SMAUG-T key encapsulation mechanism, which will begin pilot deployments in 2027.
* China’s NGCC: The national cryptographic standards being developed and mandated within China.

This global-minded approach provides multinational corporations, software vendors, and hardware manufacturers with a single, unified tool to ensure their products are compliant across different regulatory jurisdictions, significantly simplifying the challenge of global PQC adoption.

Forging Alliances for a Quantum-Resistant Future

Tackling the quantum threat requires a collaborative, ecosystem-wide effort. Recognizing this, pQCee has forged strategic partnerships with other leaders in the security space to deliver a comprehensive, end-to-end solution.

The company is working with PQShield, a prominent PQC specialist, to integrate its FIPS 140-3-certified cryptographic library. This collaboration ensures that the algorithms running within pQCee's framework are not just theoretically sound but have been rigorously tested and certified to a high government standard.

Johannes Lintzen, Global Director of Business Development at PQShield, highlighted the importance of this integration. “pQCee’s CNG provider creates an important bridge between standards-based implementations of PQC and real-world Windows deployments,” he said. “By collaborating...we’re ensuring that proven post-quantum cryptography can be used through a mainstream system interface...This offers a clear, standards-based way to bring quantum-safe capabilities to Windows environments well ahead of the migration timeline.”

Furthermore, a partnership with Feitian Technologies, a global provider of security hardware, ensures the solution can be anchored in physical security. This allows for the integration of PQC with hardware like smartcards, USB tokens, and Hardware Security Modules (HSMs), providing a robust, hardware-based root of trust.

“We are delighted to partner with pQCee to bring hardware-based post-quantum security to the Windows platform,” stated Mr. Geoffrey Li, International Technical Director at Feitian Technologies.

From Theory to Practice: Lowering the Barrier to PQC Adoption

Despite the clear and present danger, many organizations face significant hurdles to PQC adoption. These include a lack of in-house expertise, the complexity of integrating new algorithms into legacy systems, and concerns about performance overhead.

pQCee’s CNG provider is designed to directly address these pain points. By building on top of a standard Windows API, it abstracts away much of the underlying complexity. Developers can call on quantum-resistant cryptographic functions without needing to become PQC experts themselves, dramatically lowering the barrier to entry and accelerating development cycles. While Microsoft has begun integrating some NIST PQC algorithms into Windows, pQCee's offering provides a broader, more flexible layer of agility that encompasses a wider range of algorithms and national standards.

This approach transforms the daunting task of PQC migration from a revolutionary overhaul into a manageable, evolutionary process. Organizations interested in seeing the solution in action can visit the pQCee booth (S-1945) for a live demonstration at the upcoming RSAC Conference 2026.
