Your Shield, Our Promise:
The Three Rings of IP Phone Security
Core Ring: Device Integrity
With Trusted Execution Environment, secure boot, integrity verification, firmware encryption and signature
certificate, it ensures integrity from startup to operation.
TEE:
Hardware-Trusted, Threat-Proof
Security Isolation
TEE provides a hardware-isolated environment that keeps sensitive data separate, invisible, and strictly access-controlled.
Data Encryption
TEE auto-encrypts data with hardware-protected keys, preventing decryption if intercepted.
Secure Storage
Sensitive data and keys are securely stored within the TEE with hardware encryption. For enterprise-grade protection, critical keys can also be managed and safeguarded by a Hardware Security Module (HSM), ensuring that data remains protected both locally and in centralized systems.
