Features and Security



Cryptosmart secures the connection of mobile devices to your IS and the Internet, using a highly secure, remotely configurable VPN.

All traffic (browsers, applications, email...) is tunneled through the VPN, at any time, on any network (Wi-Fi, 3G, 4G, 5G) and any circumstance.


Secure communications

With Cryptosmart, protect all your sensitive business communications within and between entities:
- End-to-end encrypted calls or encrypted calls to your IS.
- End-to-end encryption of SMS communications*

*A subscription with a mobile operator is required (SIM or eSIM card)


Local protection

Local data encryption is activated as soon as your device is powered, to protect against loss or theft. This local encryption is performed using your own cryptographic keys.

Port control (USB, Bluetooth, Wi-Fi...), application installation and other security policy parameters are also managed by Cryptosmart.



Fleet mode

To meet the challenges associated with agility, you can configure Cryptosmart devices in Fleet mode, so that a single device can be used by several users on the same team, enabling flexibility and availability of mobile devices for the right operational need. Fleet mode provides total, centralized control of mobile devices, limiting access to only the applications needed, while quickly handing the device over to the next user who needs it.

Mobile desktop mode

Cryptosmart is compatible with Samsung DeX and Mirabook, so you can turn your device into a computer. By connecting the smartphone to a monitor or computer, the Samsung DeX platform starts up quickly, allowing you to work securely with your mobile device’s data. Or by using a Mirabook, your data is always safe on your Samsung device with Cryptosmart.
