The government of Pakistan has hired a Canadian firm, Sandvine to monitor internet traffic in the country. Sandvine is considered as a “controversial firm” due to the illegal sale of their services to the governments of Turkey, Egypt, and Syria in the past. Despite the controversial background, Pakistan Telecommunication Authority (PTA) signed a contract with Sandvine after failing to build their own suitable technical solution for monitoring, and restraining grey traffic.
Sandvine will provide tools for monitoring and analyzing all incoming and outgoing internet traffic from Pakistan and will use the Deep Packet Inspection (DPI) to monitor every single activity on the internet within Pakistan.
