# Symmatrics Launches Quantum-Safe VPN to Combat Modern Security Threats
Symmatrics has unveiled its Quantum Protected Network (QPN), a next-generation VPN designed to counter both today’s credential-based attacks and tomorrow’s quantum computing threats. Rather than relying on traditional password-based authentication, the QPN uses device verification and single-use symmetric encryption keys—a method inspired by decades of intelligence community practices.
The platform addresses critical vulnerabilities in legacy VPNs: stolen credentials, long-lived session keys, and predictable encryption patterns. By rotating encryption keys continuously at the session level and eliminating credential dependency, the QPN protects against current breaches while safeguarding encrypted data from potential future quantum decryption attempts.
Built for enterprises managing distributed workforces and private cloud infrastructure, the QPN integrates seamlessly into existing networks without requiring application changes or major redesigns. It supports all TCP and UDP traffic while enforcing device-based access controls—ideal for regulated industries like finance and government.
