From Ron Deibert:

The LGBTQ news website, “Gay Today,” is blocked in Bahrain; the website for Greenpeace International is blocked in the UAE; a matrimonial dating website is censored in Afghanistan; all of the World Health Organization’s website, including sub-pages about HIV/AIDS information, is blocked in Kuwait; an entire category of websites labeled “Sex Education,” are all censored in Sudan; in Yemen, an armed faction, the Houthis, orders the country’s main ISP to block regional and news websites.

What’s the common denominator linking these examples of Internet censorship? All of them were undertaken using technology provided by the Canadian company, Netsweeper, Inc.

In a new Citizen Lab report published today, entitled Planet Netsweeper, we map the global proliferation of Netsweeper’s Internet filtering technology to 30 countries. We then focus our analysis on 10 countries with significant human rights, insecurity, or public policy issues in which Netsweeper systems are deployed on large consumer ISPs: Afghanistan, Bahrain, India, Kuwait, Pakistan, Qatar, Somalia, Sudan, UAE, and Yemen. The research was done using a combination of network measurement and in-country testing methods. One method involved scanning every one of the billions of IP addresses on the Internet to search for signatures we have developed for Netsweeper installations (think of it like an x-ray of the Internet).

National-level Internet censorship is a growing norm worldwide. It is also a big business opportunity for companies like Netsweeper. Netsweeper’s Internet filtering service works by dynamically categorizing Internet content, and then providing customers with options to choose categories they wish to block (e.g., “Matrimonial” in Afghanistan and “Sex Education” in Sudan). Customers can also create their own custom lists or add websites to categories of their own choosing.

Netsweeper markets its services to a wide range of clients, from institutions like libraries to large ISPs that control national-level Internet connectivity. Our report highlights problems with the latter, and specifically the problems that arise when Internet filtering services are sold to ISPs in authoritarian regimes, or countries facing insecurity, conflict, human rights abuses, or corruption. In these cases, Netsweeper’s services can easily be abused to help facilitate draconian controls on the public sphere by stifling access to information and freedom of expression.

While there are a few categories that some might consider non-controversial—e.g., filtering of pornography and spam—there are others that definitely are not. For example, Netsweeper offers a filtering category called “Alternative Lifestyles,” in which it appears mostly legitimate LGBTQ content is targeted for convenient blocking. In our testing, we found this category was selected in the United Arab Emirates and was preventing Internet users from accessing the websites of the Gay & Lesbian Alliance Against Defamation (http://www.glaad.org) and the International Foundation for Gender Education (http://www.ifge.org), among many others. This kind of censorship, facilitated by Netsweeper technology, is part of a larger pattern of systemic discrimination, violence, and other human rights abuses against LGBTQ individuals in many parts of the world.

According to the United Nations Guiding Principles on Business and Human Rights, all companies have responsibilities to evaluate and take measures to mitigate the negative human rights impacts of their services on an ongoing basis. Despite many years of reporting and numerous questions from journalists and academics, Netsweeper still fails to take this obligation seriously.
