Are You Ready for the Quantum Cyber Threat?

Quantum computing is poised to revolutionize industries, but poses one of the biggest cybersecurity threats. Once quantum systems mature, today’s encryption methods—RSA, ECC, and others—could be cracked in hours using algorithms like Shor’s.

Cybercriminals are already harvesting encrypted data for a quantum future ("Harvest Now, Decrypt Later"), putting sensitive government, financial, and healthcare data at risk.

Forward-looking organizations must start transitioning to Post-Quantum Cryptography (PQC). To address these risks, the U.S. NIST has already introduced quantum-safe algorithms like CRYSTALS-Kyber and Dilithium.

What’s at Stake?

  • Secure web (HTTPS), VPNs, email encryption, and blockchain systems

     

  • National security, intellectual property, and personal records

     

  • Global cyberespionage, economic disruption, supply chain vulnerabilities

     

Key Actions to Prepare:

  1. Conduct a quantum-risk data inventory

     

  2. Implement cryptographic agility in systems.

     

  3. Pilot PQC algorithms early

     

  4. Train your IT/security teams on quantum risks.

     

  5. Update vendor encryption policies.

     

  6. Monitor global quantum developments.

     

Why Act Now?
Quantum threats may be 10–20 years away, but securing your infrastructure and data can take just as long. If you wait until quantum computers arrive, it’s already too late.

quantum-resilient future is not a luxury—it’s a business necessity.
