Our information system provides a highly secure connection, with government-level security on Cryptosmart PC. ERCOM's Gateway is integrated to enhance security, while ERCOM's CyberSIM offers additional hardware protection. Encryption keys are managed by the customer/administrator, ensuring total control. For users, security is transparent: all you need is a USB key with the CyberSIM and a PIN code.


Secret Management

A single software package, CardManager, allows you to use your own cryptographic keys from your Key Management Infrastructure (KMI) in Cryptosmart Gateway and PCs.

It enables devices to be managed remotely.

Redundancy and increased capacity are easily implemented.



In addition to the VPN, Cryptosmart PC can be installed on any PC running Windows or Linux, and allows you to manage parameters in line with your security policy (USB, Bluetooth, Wi-Fi...).

Fully deployable and manageable remotely, the solution offers flexibility for mobile workers.
