Terrorism is a significant concern worldwide. Criminals, jihadists, and terrorists are quick to use technology to protect their anonymity, privacy, modes of operation, and secret antisocial plans. They adapt to new innovations and exploit any technological advantages as means to ends. Clandestine operations are used to raise funds. Criminals, jihadists, and terrorists are working in international cells and rings that contest geographical boundaries and that require large resources and international security cooperation to obstruct their activities. Addressing these cross-country challenges require cross-country cooperation. The aim of this essay is to analyze the role of Internet intermediaries in countering online terror. I argue that Internet intermediaries can and should do far more than what they do to proactively fight online terrorism and that self-regulation is not effective enough. It is time for governments to step in and to protect vulnerable third parties by demanding that Internet intermediaries be vigilant and proactive in fighting terror. The idea of a new browser, CleaNet, is proposed to ensure a safe environment for Net users and for society at large.
