Seamless remediation
Plug-and-play APIs
Available all languages. Easy to integrate into any stack.
True Cryptographic agility
Seamlessly update algorithms as threats evolve, no need to touch your code post integration.
Zero-maintenance
We handle upgrades, patches, and algorithm transitions behind the scenes.
Backed by Research. Certified for Reality.
PQCaaS was built for real-world attack surfaces, not just academic theory. Our architecture is ISO 27001 certified and shaped through technical collaboration with cryptographers at Deakin and RMIT University.
Our approach has been validated through peer-reviewed research and continuous testing to ensure operational security in live environments.

Cloud-Based with PQ-TLS (Most popular)
Most users can get started with our pre-configured PQ-TLS, combining quantum-safe KEMs with ECC for seamless hybrid encryption. Great for application layer security such as end-to-end encryption, digital signing (e.g. doucments) and seamless PQC integration.

Pre-Shared Key Mode
For constrained devices and intermittent networks, we offer a PSK mode that minimizes latency and TLS dependency. Ideal for embedded systems, IoT, drones, and critical infrastructure.
On-Premise for High-Sensitivity Environments
For enterprises with strict compliance or sovereignty requirements, we offer two models:
- API-hosted on client servers: Full ExeQuantum functionality with update control retained by us.
- Code handover: For maximum independence, source or binaries (Python, C, JS) can be licensed. Includes contractual protections for our IP and engineering support as needed.
