True Zero-Trust vs A Walled Garden
True Zero-Trust vs A Walled Garden
Most enterprise communication platforms—including those branded as "secure"— assume the internal environment is trusted, and security is enforced primarily at the network boundary. Even "secure" communications systems often rely on TLS and SRTP encrypted tunnels to encrypt data in transit, but only within a trusted perimeter.
These protocols terminate at servers or gateway devices, exposing session keys, messages, or media to inspection and compromise. This model, known as the Walled Garden, assumes everything inside the fence is safe.
But what if the garden is already breached? Or worse, what if the breach is invisible?

Cellcrypt's architecture does not stop at transport encryption (TLS/SRTP). Instead, it establishes application-layer tunnels that wrap encrypted payloads in a secondary, end-to-end encrypted envelope.
These tunnels are anchored by:
Unique session keys derived per call/message
Authenticated key exchange using ECC and post-quantum KEMs
Encryption that never terminates at the server
The Result: Even if the network, VPN, or Cellcrypt’s own infrastructure are compromised, the payload remains encrypted, unreadable, and non-replayable.
