Quantum-Resilience Communications Infrastructure
Designed for governments and regulated organizations – Sovereign implementation possible – European infrastructure
The infrastructure behind secure communication
Long-term protection in a post-quantum reality
Communication intercepted today may be decrypted in the future.
KeyPact develops quantum-resilient communication infrastructure for organizations with public and societal responsibility.

Post-Quantum Cryptographic Architecture
KeyPact integrates post-quantum cryptography at the core of the infrastructure. Data is protected before it reaches external systems or cloud environments. This ensures confidentiality remains intact even under legal pressure, cloud access, or future quantum threats. The cloud transports data, but has no cryptographic control over the content.

Forward Secrecy as a structural principle
Each session uses temporary keys, ensuring that historical communication cannot be decrypted if long-term keys are compromised. This structurally strengthens confidentiality and aligns with compliance requirements in governments and critical infrastructure.

Sovereign implementation
KeyPact can be fully deployed on-premise or within private cloud environments. Data, keys, and policies remain under the direct control of the organization. This makes digital sovereignty not only possible, but technically enforceable — even in highly regulated sectors.

Layered cryptographic protection
The infrastructure combines post-quantum key exchange, strong symmetric encryption, and forward secrecy. This layered approach ensures that confidentiality is preserved even if one layer fails.

Secure communication as an application
The KeyPact infrastructure supports applications such as secure email. Communication is cryptographically protected before it reaches mail servers or cloud environments. The infrastructure ensures that external parties have no technical access to the content.

Integration without behavior change
KeyPact can integrate with existing email environments such as Outlook and Google Workspace. Users retain their familiar way of working, while the underlying communication is protected with quantum resilience — without extra actions or complexity.
KeyPact PQ-Mail Proxy: From trust to cryptographic control
Joop van Veen, directeur Veen & Zn.
Sector-specific designed for high-trust environments
Structural digital resilience for organizations with heightened compliance requirements KeyPact supports organizations that must comply with NIS2, governance requirements, and sectoral regulations. The infrastructure automates cryptographic protection without losing control or auditability.
By fully automating complex security, KeyPact finally makes cybersecurity accessible to all types of businesses.

The cryptographic world can roughly be divided into three paradigms: classical cryptography, post-quantum cryptography (PQC), and quantum cryptography. Each of these paradigms has its own mathematical assumptions, implementation requirements, and role in the migration strategy toward quantum-safe security. Classical cryptography (pre-PQC) Classical public-key cryptography forms the basis of the current Public Key Infrastructure (PKI). Post-Quantum cryptography (PQC) Post-quantum cryptography […]
Why KeyPact sets the new standard for secure journalistic communication Source protection forms the foundation of independent journalism. Without the certainty that sources can communicate securely and, if necessary, anonymously, investigative journalism will inevitably dry up. In the current digital media landscape, however, that certainty is far from self-evident: cloud platforms, email services, and chat apps are primarily designed for accessibility and […]
Quantum-proof email as the foundation for digital sovereignty Technology, law, and geopolitics in conjunction Why this topic is policy-relevant now The confidentiality of government communication is structurally under pressure. Not primarily due to current cyber attacks, but due to a strategic time effect: communication intercepted today can be stored and later decrypted once quantum computers have sufficient computing power […]
