SR2 Communications builds open source systems and processes to support human rights defenders, journalists, community groups and activists. Through the hosting of circumvention tools, including web mirrors and Tor Bridges, they provide free and open access to information to users facing censorship.
Using privacy-preserving techniques, SR2 collects data from these tools to make dynamic deployment decisions, adapting in real time to shifting censorship conditions. This continuous optimisation maximises the likelihood that any user can reach the information they need on any given day.
