Antisemitism

Threats to Jewish communities and weaponised antisemitism are on the rise, driven by extremists, hostile governments and conspiracy theorists. Combining our best-in-class digital research techniques with in-depth subject matter knowledge of extremist movements, ISD tracks antisemitism at scale and informs policymakers globally. We also build capacity amongst civil society groups through initiatives such as our Coalition to Combat Online Antisemitism (CCOA).
