The Online Harms Foundation implements the UN-supported public-private partnership Tech Against Terrorism in partnership with the Global Internet Forum to Counter Terrorism (GIFCT). In 2020 we relaunched as the Online Harms Foundation in order to broaden the practical support we offer to smaller tech platforms to include countering the terrorist use of the internet, child sexual abuse material (CSAM), online scams, and disinformation whilst respecting human rights. Through our work in implementing Tech Against Terrorism since 2017 we have pioneered an effective public-private partnership model that brings together experts from the tech community, academic, civil society, and government to provide practical support to platforms. The Online Harms Foundation currently receives no funding for its own work, however Tech Against Terrorism is funded by Public Safety Canada (for the development of the Terrorist Content Analytics Platform – the TCAP), by the GIFCT to provide free Mentorship services to smaller tech platforms in need of support to tackle terrorist use of their services, and by other platforms on ad hoc basis to provide Open Source Intelligence (OSINT) expertise. Our preference is to receive 50:50 funding from the public and private sectors to reinforce the principle of independence and reinforce the importance of public-private partnerships as recognised by the UN Security Council. The GIFCT is backed by Facebook, Microsoft, Google, Twitter, Amazon, and others. Previously we have received funding from the Government of Switzerland, the Republic of Korea, and the Government of Spain.
