For 20 years, ISD has delivered field-leading threat detection, analysis and real-world strategies to combat terrorism, extremism and authoritarianism - in all their ideological forms.

Islamist Extremism

Islamist Extremism presents a politicised supremacist vision of Islam that is antithetical to democracy and human rights. Since the Islamic State (IS) and Al Qaeda’s high water mark a decade ago, Islamist Extremist movements are in a state of flux, spreading across a broad range of violent and political groups globally. We track and respond to these evolving threats using a range of tools and approaches, as well as trying to reach an increasingly young cohort of digital supporters.”
