Getting started

Welcome to the SSL VPN administration guide for Stormshield SNS firewalls and SSL VPN clients.

In this guide, Stormshield Network Security is referred to as "SNS firewall", and Stormshield Network SSL VPN Client is referred to as "Stormshield SSL VPN client".

SSL VPN allows remote users to securely access an organization's resources - internal or otherwise - via the SNS firewall. An SSL VPN client must be installed on the user’s workstation and/or mobile device before they can set up SSL VPN tunnels with the SNS firewall.

Once the SSL VPN tunnel has been set up, communications between the user and the SNS firewall are encapsulated and protected through an encrypted TLS tunnel, referred to in this guide as an "SSL VPN tunnel".
