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.

Threat Analysis and Prevention

Online ecosystems have an enormous impact on the offline world. Our threat analysis and prevention practice involves monitoring online extremist ideologies, hostile states and other bad actors to identify and mitigate potential threats before they escalate into offline violence or criminal behaviour. Our team of digital analysts and subject matter experts can research and track a range of bad actors – including extremist groups, radicalised individuals and hostile states – to detect and prevent violent threats.

ISD offers a unique rapid response capability: we can provide partners with real-time analysis of incidents (from global conflicts to politically motivated attacks) at nearly any hour. This support helps stakeholders swiftly respond to evolving crises and minimise harm on the ground. Please email us at [email protected] if you would like to learn more about this work.
