The Joint State Threats Assessment Team (JSTAT) is a cross-departmental assessment organisation that provides analysis on the hybrid state threats to the UK and UK interests. We assess the national security threat posed by activities such as espionage, assassination, interference in our democracy, threats to the UK’s economic security and the UK’s people and assets overseas.

JSTAT provides assessment for a wide range of HMG departmental customers, focusing on centrally-agreed priorities as well as direct tasking from policy and intelligence customers.

 


Organisation

JSTAT officers come from a wide range of government departments, bringing a diverse set of skills and understanding. Like other assessment bodies, including the Joint Terrorism Assessment Centre, JSTAT reports to a Governance Board comprising senior officials from across the UK intelligence community and wider policy departments, with the Director General of MI5 having ultimate responsibility for the organisation.


Collaboration and Innovation

Collaboration is at the heart of what we do. JSTAT works across government and beyond to provide timely and impactful assessments.
