QSphere VPN – Quantum-Resilient Remote Access

QSphere VPN, developed by QuantumGate and the Technology Innovation Institute (TII), is a quantum-resilient secure remote access platform for organizations that need strong encryption, strict control of sensitive data, and flexible deployment across AWS, on-premises, and hybrid environments. It is designed for customers that want the convenience of AWS Marketplace procurement without being locked into a cloud-native-only architecture. On AWS, QSphere VPN can be deployed on customer-managed Amazon EC2 instances inside an Amazon VPC, allowing organizations to align remote access with their existing network segmentation, routing, identity, and monitoring practices. Where configured, deployments may use AWS CloudFormation for repeatable provisioning and Amazon CloudWatch for operational visibility, while retaining the option to lift and shift the same secure access model to private data centers or other approved environments. QSphere VPN applies Zero Trust principles by continuously verifying user identity, device posture, and application access before allowing connectivity. Its policy-driven model supports least-privilege access, granular application controls, and reduced lateral movement risk. The platform combines classical and post-quantum cryptography in a crypto-agile design, helping enterprises prepare for evolving cryptographic standards while maintaining interoperability with existing infrastructure. Key Features: • Hybrid cryptography: Combines classical and post-quantum algorithms for long-term resilience. • Crypto agility: Supports adaptation to evolving cryptographic standards and PQC mandates. • Zero Trust access: Enforces identity, device, and application-level verification. • Granular controls: Applies least-privilege policies to help prevent lateral movement. • Session protection: Uses unique, ephemeral keys to protect access sessions. • Device posture checks: Helps block compromised or non-compliant endpoints. • AWS-ready deployment: Runs on Amazon EC2 within Amazon VPC while preserving on-premises and hybrid portability. QSphere VPN helps government, enterprise, and critical-infrastructure customers build post-quantum-ready remote access while keeping operational choice, data control, and deployment flexibility intact.
