Security guidelines that inSync uses for remote backup

The following features makes inSync secure and ready for deployment for your WAN and VPN users :

  1. 256-bit SSL network encryption

  2. 256-bit AES storage encryption

The client triggered architecture ensures that backup and restore requests are always initiated by the inSync clients. The inSync server (just like the e-mail and HTTP servers) never initiates an outbound request. This facilitates secure deployment in your DMZ, with just one-way inward (ANY to 6061) port forwarding in your firewall.
