Outbound-only reverse tunnels improve security by ensuring that no ports are open
to the public internet. Instead of a remote user connecting directly into the network,
a secure connector inside the environment initiates an outbound connection to a 
trusted proxy. This setup effectively hides the network from search engines and 
scanners, eliminates the vulnerabilities associated with inbound port forwarding,
and works seamlessly across network address translation and non-public internet 
protocol environments. Learn more about the [advantages of an outbound-only network](https://www.agilicus.com/compare/).
