In a nutshell, …
Safing consist of multiple components:
The Portmaster is an application firewall and transparently takes over DNS to ensure your privacy and security. It handles most decisions on its own based on behavioral profiles, intelligent decision making and crowdsourced intelligence. It will only disturb you if necessary. We do not do deep packet inspection, nor do we break TLS - on the contrary, we strenghten it by thoroughly checking it.
Port17 is global high speed mesh network - it allows you to be everywhere, at the same time. It routes your connections to the Internet through multiple hops as close as possible to the final destination to minimize the path in the visible Internet. Every connection is handled and secured seperately.
