Symmatrics is a Vienna, Virginia cybersecurity company building quantum-secure encryption infrastructure based on one-time pad symmetric keys delivered at internet scale. Its platform replaces public-key exchange with continuously delivered, single-use symmetric keys, which the company positions as information-theoretically secure and therefore resistant to future quantum attacks. Products span a developer SDK, a quantum-protected VPN, and an authentication and access management layer. The company, formerly named Matrics2 Inc., opened its Tysons Corner headquarters in 2026 and was founded by scientists with government security backgrounds.
