Sky ECC is built on a zero-trust security model. We don’t rely on other’s assurances of security, so we protect Sky ECC from threats inside and outside of the device.

Security Layers

Multi-layer app protections leveraging hardware, OS, app security, and password layers
Deploying on devices with tamper-resistant hardware and operating systems
Managing and locking down devices with Bluetooth, cameras, and other features disabled
Impenetrable brute force protection
No data stored on messaging servers
Private keys remain on the device and never stored or sent to our servers
Secure gateway automatically encrypts, protects, and anonymizes network traffic
Users cannot log into Sky ECC over insecure networks
Apps outside of the Sky ECC container have no access to Sky ECC data (and vice versa)
AES 256 encrypts message headers and metadata
Messages and Vault items are encrypted with 521 bit elliptic curve cryptography
Message and Vault employ separate passwords for access and separate brute force protections.

Sky ECC operates on a secure global communications network supporting tens of thousands of users in over 150 countries.
