Multi-perimeter firewall in the cloud
Systems and methods for providing multi-perimeter firewalls via a virtual global network are disclosed. In one embodiment the network system may comprise an egress ingress point in communication with a first access point server, a second access point server in communication with the first access point server, an endpoint device in communication with the second access point server, a first firewall in communication with the first access point server, and a second firewall in communication with the second access point server. The first and second firewalls may prevent traffic from passing through their respective access point servers. The first and second may be in communication with each other and exchange threat information.

an endpoint device in communication with the second access point server;
a first perimeter firewall in communication with the first access point server, wherein the first perimeter firewall performs stateful packet inspection to prevent at least some traffic from passing from the first access point server to the second access point server using a first firewall mechanism; and
a second perimeter firewall in communication with the second access point server, wherein the second perimeter firewall performs deep packet inspection to prevent at least some traffic from passing from the second access point server to the end point device using a second, different firewall mechanism,
wherein at least one of the egress ingress point device, the first access point server, the second access point server, the endpoint device, the first perimeter firewall, or the second perimeter firewall comprises hardware,
wherein the deep packet inspection is performed on a cloned copy of traffic that flows through the second perimeter firewall.
