Zscaler Moves to Quantum-Safe Cryptography to Protect Against Future Threats

Quantum-safe cryptography replaces algorithms that can be broken by quantum computing with new ones built to withstand it. These include lattice-based, hash-based, and multivariate polynomial systems. Zscaler is integrating quantum-resistant protocols into its cloud-native security platform to protect data in transit and at rest against future quantum attacks.

Current encryption like RSA and ECC rely on problems that quantum computers can solve in seconds once they reach scale. The National Institute of Standards and Technology (NIST) is standardizing next-generation algorithms, and Zscaler is aligning its architecture with these standards. This ensures encrypted tunnels, SSL inspection, and Zero Trust applications remain secure even when quantum decryption becomes practical.

Deploying quantum-safe cryptography at scale is not trivial. It requires re-engineering authentication flows, updating libraries across distributed systems, and testing for performance regressions. Zscaler’s approach focuses on seamless migration within their security fabric so customers are protected without disruption.

The urgency is real. Adversaries can harvest encrypted data now and decrypt it later when quantum capabilities mature. Zscaler’s adoption of quantum-safe methods blocks this “store now, break later” strategy, safeguarding sensitive communications across public and private networks.

Migrating early means securing your infrastructure against both present and future threats. Don’t wait until the breach is unfixable. See quantum-safe cryptography in action and launch secure systems yourself—visit hoop.dev and start building in minutes.
