It’s now a well-established fact that ICT companies have major power over users’ ability to enjoy and exercise their human rights - online as well as “in real life.” As a result, more and more civil society actors are researching the inner workings of companies and developing advocacy campaigns to influence them. However, researchers often face obstacles including lack of corporate transparency, legal issues, and difficulty developing a collaborative relationship with companies, and the strategies that have served us well in engaging with government actors don’t always translate to working with the private sector. For example, executives of many companies are not familiar with the connection between privacy, data protection, security and human rights. Other company officials may be familiar with transparency as a tool to fight corruption, but do not see the connection between transparency, human rights, and the business operations of an ICT company, even though these issues are well-understood at other levels of the same company. In this session, seasoned researchers and advocates will discuss how they use various tools to understand what's going on inside companies, and share their insights on to conduct company-oriented advocacy in a way that company representatives will actually engage with.
