Phishing, business email compromise, and credential harvesting cost enterprises tens of billions a year — and every email a human can click is a potential breach. Symmatrics secures email at the protocol layer: encrypting content with one-time symmetric keys and eliminating the credential theft that makes email-based attacks so effective. Mathematically Unbreakable Encryption™, NIST-aligned.
Email is breached two ways at once: the content is interceptable in transit, and the credential that protects the account is harvestable. Awareness training can’t fix a structural vulnerability in credential-based authentication, and standard TLS only guards against passive interception. In a post-quantum world, traffic captured today becomes readable tomorrow.



Symmatrics addresses email at two layers simultaneously. The SDK wraps message content — and the API traffic behind email platforms — with one-time symmetric keys; even if traffic is intercepted, the key no longer exists to decrypt it later. AuthAM replaces the account password entirely, so there’s no credential to phish, stuff, or reset. Together they close the surface that makes email the most productive breach vector in the enterprise.

Symmatrics is a team of SaaS encryption pioneers, who have developed a suite of products designed to raise the standard of encryption now, and in the quantum future. We accomplish this goal by delivering the most secure symmetric keys at scale.
Traditional encryption relies on public or shared keys that can eventually be broken as computing power increases. Symmatrics uses a new symmetric-key delivery model that eliminates those dependencies, offering a simpler, more resilient, and future-ready approach to secure data exchange.
Yes. By avoiding public key cryptography entirely and relying on ephemeral symmetric keys, Symmatrics is inherently resistant to quantum attacks. This is also how we can guarantee 'Mathematically Unbreakable Encryption'.
While Symmatrics is ideal for any organization that manages sensitive, regulated, or mission-critical data that needs to be encrypted securely, we find the most immediate value and response from financial institutions, cloud security offerings, as well as the urgently growing casino/gaming space.
The Software Development Kit (SDK) enables integration of Symmatrics technology into existing applications or infrastructure. It provides a secure, standardized way to facilitate key distribution to authorized devices for quantum secure encryption.
