The Community Security Trust (CST) is a British charity established in 1994 to ensure the safety and security of the Jewish community in the UK. It follows a history of Jewish defence organisations in the United Kingdom dating back to the 1930s. The CST provides security advice and training for Jewish schools, synagogues and communal organisations and gives assistance to those bodies that are affected by antisemitism. The CST also assists and supports individual members of the Jewish community who have been affected by antisemitism and antisemitic incidents. It advises and represents the Jewish community on matters of antisemitism, terrorism and security and works with police, government and international bodies. All this work is provided at no charge.
