The Backdoor Problem

Firewalls seal, but most of them leak!

Most of the firewalls and UTM appliances offered in the IT security market provide secret access for external authorities over so-called "hidden backdoors".
That's a fact, see for example "The Communications Assistance for Law Enforcement Act" in the United States, a law applicable to the Internet since 2004, which has been abused and is still abused to spy on companies all over the world.
So, does it really make sense to buy a firewall or UTM if someone still has access to copy all of your incoming and outgoing traffic?
Of course it does ... BUT... make sure to decide for a firewall or UTM appliance WITHOUT BACKDOORS.
