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. Included in its work countering antisemitism is monitoring criticism of Israel. 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. (run by interfaith organisation Faith Matters), with which it now works closely.
Research The CST has recorded antisemitic incidents in the UK since 1984 and publishes an annual Antisemitic Incidents Report. The organisation does not release details of its methodology. The CST's work countering antisemitism includes Anti-Zionism which it views as a euphemism for “Jewishness” and “Jew”. In its most recent report on antisemitism 43% of incidents involved Anti-Zionism. In the same report the CST recorded 355 instances "wherein the phrase “Free Palestine” was used for antisemitic purposes." The CST also published
Terrorist Incidents against Jewish Communities and Israeli Citizens Abroad 1968-2010, a definitive report of terrorist attacks against Jewish communities around the world. In 2003, the charity worked with the
Board of Deputies of British Jews to submit a report concerning
Iran and antisemitism to the
Foreign Affairs Select Committee. In 2023, the CST recorded 4,103 antisemitic incidents in the United Kingdom, the highest reported in a calendar year, and an increase of 147% compared to 2022. The figures spiked after the
2023 Hamas-led attack on Israel. In the first half of 2024, 1.978 antisemitic incidents were reported.
Online abuse The CST has been active in monitoring and attempting to combat extremist activity online. In 2019, the CST recorded 1,805 incidents of antisemitic abuse, 697 of which were online. During the
COVID-19 pandemic, the CST reported in 2020 that it had recorded a drop in physical assaults on Jewish people in the UK, but had noted an increase in online abuse, including
antisemitic conspiracy theories accusing Jewish people of
engineering the pandemic as a "hoax" or spreading COVID-19, among other antisemitic content. The charity had also said that it noticed far-right commentators online discussing spreading COVID-19 to synagogues.
The Guardian reported that CST's analysis discovered posts on
Telegram which "...celebrat[ed]
Thomas Mair and
David Copeland, and other far-right terrorists." In early 2021, the CST reported the website BitChute to
Ofcom for content it considered antisemitic, hateful, and extremist. The CST has scrutinized other platforms such as
Facebook and
Twitter for antisemitic content. The charity was among the groups that worked with
TikTok to develop a
Holocaust education initiative launched in early 2021. After the
storming of the Capitol in the United States in January 2021, the CST warned that calls for similar events to take place in the United Kingdom, including a proposed storming of
Parliament or
Downing Street, were appearing in far-right spaces online. ==Funding and finances==
