Company Overview

QuantaSeal is a post-quantum cryptography middleware company headquartered in Adelaide, South Australia. The company provides a universal bidirectional quantum-safe security platform that protects enterprise data, APIs, and credentials against current and future quantum computing threats.

QuantaSeal's platform implements NIST FIPS 203/204/205 post-quantum cryptography standards (ML-KEM-768, ML-DSA-65, SLH-DSA) in a hybrid mode with AES-256-GCM, providing enterprise-grade security that is quantum-safe today.

The platform serves regulated industries including financial services (APRA CPS 234, DORA), healthcare (HIPAA), government (CMMC 2.0, NIST SP 800-171), and any enterprise facing compliance obligations for data protection and cryptographic security.

Founding Story

QuantaSeal was founded in Adelaide in 2025, motivated by a clear and present threat: within 5–15 years, cryptographically relevant quantum computers will be capable of breaking RSA-2048 and ECDSA-256 - the algorithms securing virtually all enterprise data today.

The “harvest now, decrypt later” (HNDL) attack pattern means that adversaries are already collecting encrypted data to decrypt retrospectively. For enterprises with regulated data (PII, PHI, financial records, IP), the window to act is now - before the quantum threat materialises.

QuantaSeal was built to solve this problem in a way that enterprises could actually adopt: a SaaS middleware layer that adds post-quantum cryptography to existing systems without requiring organisations to rebuild their infrastructure. The bidirectional proxy model means QuantaSeal can be deployed in weeks, not months.
