Your data is decrypted every time it's processed.
That's where breaches happen.

Every database query, every AI inference, every API call exposes plaintext. H33 eliminates the plaintext window with fully homomorphic encryption. One API call. No infrastructure changes.

The problem

Encryption fails during processing.

  • Database queries require plaintext — a breach exposes everything
  • AI models process data in GPU memory — unencrypted
  • API calls transmit plaintext payloads
  • Compliance audits can't prove data was never exposed

Every field readable by anyone with access.
The solution

Process data without decrypting it.

H33 wraps your existing infrastructure with post-quantum FHE. Your databases, AI models, and APIs operate on encrypted data. The plaintext never exists on your servers.

  • Databases store and query ciphertext
  • AI models run inference on encrypted data
  • ZK-STARK proofs verify without revealing
  • One REST API call — no crypto expertise needed
