Secure Remote Access

A Bidirectional Communication Channel from a Network Operations Center (NOC) to a Remote Site

The Lantronix Secure Remote Access (SRA) solution creates a secure tunnel to provide a bidirectional communication channel from a Network Operations Center (NOC) to a Remote Site. The solution generally does not require configuration changes to the Remote Site Firewall.

The Remote Access Device (RAD) is located at a Remote Site and initiates a connection with the Management Access Portal (MAP) located at the NOC or Host Site. Once the tunnel is established, the Network Administrator at the NOC can connect via VPN over the tunnel to devices in the same network as the Remote Access Device or through Port Forwarding to any device the RAD can address.

SRA provides the capability for a Network Managed Services company or Integrator team to configure and monitor network devices at an end-user customer site with minimal interaction with the remote network.
