Quantum Cyber Threats Are Coming—Is Your Encryption Ready?

Are You Ready for the Quantum Cyber Threat?

Quantum computing is poised to revolutionize industries, but it also poses one of the biggest threats to cybersecurity. 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 in anticipation of a quantum future ("Harvest Now, Decrypt Later"), placing sensitive government, financial, and healthcare data at risk.

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

What’s at Stake?

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

National security, intellectual property, personal records

Global cyberespionage, economic disruption, supply chain vulnerabilities

Key Actions to Prepare:

Conduct a quantum-risk data inventory

Implement cryptographic agility in systems

Pilot PQC algorithms early

Train your IT/security teams on quantum risks

Update vendor encryption policies

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.

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