The Cybersecurity Stack That Processes Data Without Ever Seeing It

Encryption at Rest Is Not Cybersecurity. Encryption During Computation Is.

Every cybersecurity vendor encrypts data at rest and in transit. Then they decrypt it to process it. That decryption window is the attack surface.

H33 eliminates the window entirely. Four FHE engines process sensitive data without decryption:

  • BFV: 2,209,429 auth/sec — biometric matching on encrypted templates
  • CKKS: 1,574 TPS — ML inference on encrypted features, 333ms dot product
  • TFHE: 768 TPS — encrypted threshold decisions
  • FHE-IQ: <500ns automatic routing between engines

What This Means for Cybersecurity

Breach yield drops to zero. If an attacker breaches the server, they get FHE ciphertexts. No key. No plaintext. No PII. The database never contains decryptable data.

Every computation is attested. H33-74 produces cryptographic proof of what computation ran, on what data, with what authorization. Three PQ signature families. Independently verifiable.

Continuous verification, not periodic audits. HATS monitors security controls continuously and produces cryptographic attestation — not questionnaire responses.
