H33, Inc. will provide free post-quantum cryptographic conversion for the first 1,000 companies requesting it, with CEO Eric Beans personally overseeing each transition. This move addresses a significant barrier to adoption: cost and complexity. Gartner estimates post-quantum migration for large enterprises ranges from 10 million to 50 million, with costs exceeding $100 million for Fortune 500 companies with complex systems. “The gap between the deadline and the current state of adoption is not a technology problem, it is a cost and complexity problem,” says Eric Beans, CEO of H33 ai, Inc. H33’s conversion will utilize three independent, NIST-standardized post-quantum cryptographic families, FIPS 203 (ML-KEM), FIPS 204 (ML-DSA), and FIPS 205 (SLH-DSA), to secure existing infrastructure.
A full cryptographic inventory of your environment is the first step in the migration plan, designed to map existing cryptographic dependencies within an organization’s infrastructure. Comprehensive inventories, previously a laborious and expensive undertaking, are becoming increasingly vital given the accelerating timeline for quantum-resistant cryptography adoption. Detailed cryptographic inventories will transition from being a reactive measure to a continuous process, integrated into standard security protocols.
Hybrid mode deployment (classical + PQ running in parallel)
H33 is implementing a hybrid mode that runs classical and post-quantum cryptography simultaneously, ensuring zero downtime during transitions and minimizing disruption to existing systems. This strategy addresses a core challenge identified by the company; the gap between looming quantum threats and current adoption rates is not a technological hurdle, but rather a matter of cost and complexity. The implementation centers on ML-KEM key exchange, directly replacing RSA and ECDH protocols without requiring extensive overhauls of established infrastructure. Industry leaders predict that this parallel approach will become increasingly common as organizations seek to mitigate risk without incurring the substantial financial burden associated with full-scale migrations. Experts anticipate that this diversification will become a standard practice, bolstering resilience against potential future vulnerabilities in any single algorithm and ensuring long-term security for critical data.

ML-DSA signatures replacing RSA/ECDSA
This multi-layered approach offers a robust defense against potential attacks from quantum computers, which pose an existential threat to current encryption methods. The inclusion of SLH-DSA as a hash-based backup family demonstrates a commitment to redundancy and resilience, providing an alternative should unforeseen weaknesses emerge in the primary ML-DSA implementation. Production validation has been completed. Experts anticipate that detailed cryptographic inventories will become increasingly crucial as organizations prepare for the full-scale deployment of these new standards, ensuring a smooth and secure transition to a post-quantum future.
KAT validation against NIST test vectors
Increased scrutiny of post-quantum cryptographic implementations is expected as organizations move beyond theoretical readiness and begin practical validation against established standards. H33 has completed Key Agreement Test (KAT) validation against NIST test vectors, a critical step demonstrating the reliability of its post-quantum algorithms in real-world scenarios. This validation process confirms the correct implementation of key exchange mechanisms, ensuring secure communication even against attacks from future quantum computers. This proactive approach aims to accelerate the adoption of post-quantum cryptography, protecting sensitive data from emerging threats and ensuring long-term security for businesses of all sizes.
Industry leaders predict a significant shift in post-quantum cryptographic adoption this year, moving beyond initial assessments toward practical implementation, and H33 is positioning itself to accelerate that transition with a unique offering. The H33 infrastructure team has processed 2.29 million attested sessions per second. Eric Beans and the team will personally oversee each transition, ensuring a robust and verified migration, emphasizing that “Every day without post-quantum protection is a day of harvest-now-decrypt-later exposure.”
