cyan AG and the Global Voice Group S.A. (GVG) have agreed on a long-term cooperation. cyan and GVG will work together to offer national cyber-security solutions to African governments and authorities with the aim to protect and increase payment flows and government revenues based on cyan's cyber-security intelligence. The first country will be Tanzania where cyan will provide a modified version of its cyber-filter for GVG solutions. GVG will be responsible for implementing the joint solution with the government and respective authorities. The functionality is based upon specific cyber-security services implemented into mobile and fixed broadband telecommunication networks. These help to determine suspicious or illegal content queried by subscribers for operators. These requests are continuously filtered in order to minimize cyber-attacks on end customers and prevent negative financial impact.
