Application: Browsec

Browsec is a VPN and browser proxying software. It allows users to bypass firewall policies. It is available as both a browser addon (Google Chrome, Mozilla Firefox, etc), and as a smartphone app. It has several modes of operation. The browser addon/extension encrypts your traffic and routes it through an SSL connection to proxy gateways. Alternatively, the smartphone app creates a legitimate IPSec (ISAKMP) tunnel over UDP to protect network traffic from firewall detections. To block Browsec addon/extensions simply enable DPI-SSL CI, or enable the Application Control signatures for Browsec. To block the IPSec VPN over UDP you must enable the ISAKMP Application Control signatures.
