Quantum Computing and Cybersecurity: Why Corporations Must Act Now

By Cyber Knowledge Partners

Quantum computing is no longer science fiction.  Even if your business will not need quantum computing capacity, not understanding how quantum will impact your cyber security and business is frankly irresponsible. Q-day, the day when quantum computing advances to the point it can break current encryption methods, is fast upon us. For corporations, this means one thing: the time to prepare is now.

The Quantum Threat to Encryption

Most of today’s encryption, including RSA and ECC, relies on the difficulty of solving large mathematical problems—something classical computers struggle with. However, quantum algorithms like Shor’s algorithm can break these cryptographic schemes in minutes, rendering decades of cybersecurity investments ineffective.

A growing concern is the “harvest now, decrypt later” tactic. Cybercriminals are already collecting encrypted corporate data with the intent of unlocking it when quantum capabilities become available. Sensitive customer records, trade secrets, intellectual property, and even historical financial data could all be compromised retroactively.

Regulatory and Industry Response

Organizations like the National Institute of Standards and Technology (NIST) are actively working to standardize post-quantum cryptography (PQC)—new encryption methods designed to withstand attacks from both classical and quantum computers. However, migration to PQC will take years, and cyber threats aren’t waiting.

Forward-thinking enterprises must not only embrace PQC but also adopt technologies that radically reduce exposure to breaches.

How Xiid Is Changing the Game

Cyber Knowledge Partners believe that one of the most promising platforms addressing these emerging threats is Xiid, a cybersecurity company pioneering a model known as Zero Knowledge Networking (ZKN).

Unlike traditional security architectures that still rely on passwords, inbound ports, and central credential storage, Xiid eliminates these vulnerabilities entirely. Here’s how:

   •       Outbound-Only Communication: Xiid removes the need for open inbound ports, drastically reducing the attack surface.

   •       SealedTunnel™ Technology: Communications are encrypted in a triple-layered tunnel, ensuring that even if a network is compromised, the data remains protected.

   •       Post-Quantum Encryption: Xiid integrates algorithms like Kyber and Dilithium, both part of NIST’s PQC candidates, making data transmission secure even in the face of quantum decryption power.

   •       Zero-Knowledge Authentication: Xiid uses one-time codes and zero-knowledge proofs, meaning no passwords are stored or transmitted—eliminating credential theft risk entirely.

By combining quantum-resistant cryptography with a completely reimagined access and transmission model, Xiid offers corporations a powerful way to future-proof their cybersecurity infrastructure.

A Call to Action

Quantum computing’s evolution is not a distant concern—it’s an active threat that will soon reshape cybersecurity forever. Corporations must begin transitioning to quantum-resilient systems today or risk catastrophic breaches tomorrow. Solutions like Xiid are not just innovative—they are essential. 

This is why it is imperative that Boards educate themselves on the risks around Cyber Security today and tomorrow.  Those who act early will not only protect their data but also gain a competitive edge in a new digital era defined by quantum risk.  Let Cyber Knowledge Partners work with you to keep your Board informed of the potential risks so you ensure good governance is in place.
