Quantum Proof Trust

Here's a scenario worth thinking about. Somewhere right now, an adversary is collecting encrypted data, diplomatic cables, health records, financial transactions, your company's intellectual property with no ability to read any of it, and they don't need to. They're betting that within a decade or two, quantum computers will crack it open like an envelope. This strategy is named Harvest Now, Decrypt Later, and it's the single biggest reason a once academic topic called quantum-proof trust is suddenly becoming a boardroom conversation.

Most of the digital trust that we rely on, like the padlock on your browser, the signature on your software updates, and the key protecting your bank login, depends on math problems that classical computers cannot solve in any reasonable time. Quantum computers eventually can. Quantum-proof trust is a multi-year project of rebuilding that foundation. The National Institute of Standards and Technology finalized three post-quantum encryption standards, the first real defense against quantum attacks.

Now, Cloudflare says that most human web traffic on its network already use post-quantum encryption. Cisco, Zscaler, and others are rolling it out too, aiming to protect a future generation that may be susceptible to evolving technology. Quantum computing is coming. The question is whether our data is ready.
