Why Most Tokenization Still Depends on Plaintext

Every compliance check in tokenization is a data exposure event. H33 makes the decisions private while keeping compliance verifiable.

Why We Built an AI That Classifies Documents It Can't Read

A purpose-built encrypted classifier that tags documents under FHE without reading them. Not an LLM. Customer-trained. Deterministic. Post-quantum attested…

Why We Ship 2,216,488 Auth/Sec — Not 2,209,429

We measured 2.2M auth/sec. We ship 1.67M. Here's exactly why the number went down, what three contended-lock bugs we found, and why the production number.

Why Your KMS Isn't Post-Quantum

Most enterprise key management systems rely on classical algorithms vulnerable to quantum computers and need upgrading now.

Why ZK Proofs Are Not Enough — You Need Attested ZK | H33 Blog

Zero-knowledge proofs prove statements. They don't prove who generated the proof, when, or under what authority. Attested ZK adds accountability.

Your Data Should Tag Itself — Without Anyone Reading It

Encrypted documents automatically classified and tagged using FHE inference. No one reads the data. No manual tagging. Policy tags drive access control.

Congratulations to Zama on Sub-Millisecond TFHE | H33 Blog

Zama broke the 1ms TFHE bootstrap barrier at 945µs on H100 GPUs. We benchmark H33's full post-quantum pipeline at 38.5µs per auth on ARM CPUs — 24x faster.
