100 Million Brazilians Disconnected from WhatsApp – Network Intelligence to the Rescue!

I was abroad this week when Brazilian court has ordered mobile operators in the country to block WhatsApp for 72 hours due to a dispute over access to encrypted data (the decision was reversed and service restored a day later). WhatsApp refused to turn over chat records related to a drug investigation to the courts, claiming these records are not accessible following the newly implemented end-to-end encryption capabilities.

Although there are many alternatives out there I can use for communicating with my family, as a regular “WhatsApper” I felt somewhat disconnected, and even strangely despaired. What I could not understand is why am I being “punished” as obviously it was not my messages that they were after. Working for Allot, I also knew that it is possible to precisely block individual WhatsApp subscribers even though the traffic is encrypted. The issue is that not all operators in Brazil have the ability to effectively filter app traffic.For more information about Network Data Source.

Deep Packet Inspection (DPI) allows mobile operators monitor and granularly analyze and filter app traffic. DPI became popular among operators with the increasing growth of mobile data as a mean to relieve network congestion by intelligently adjusting the bandwidth to each subscriber individually. It allows individual applications to be prioritized, leading to improved quality-of-experience (QoE) for every subscriber in the cell.
