## How it helps

No firewall changes at the customer’s site before you can help.

## What it does

Status: **Available** · For your team · Sessions: Support, Access · Plan: Included in Blink Core and Blink Pro

Every connection starts from the computer being helped, so the customer’s site opens nothing inbound and needs no VPN. Blink needs only a direct outbound secure connection to your Blink address, so it works through most restrictive firewalls. Networks that force traffic through a web proxy or inspect secure traffic need an exception for your Blink address.
