ISD resources for Law Enforcement

ISD supports law enforcement officials (LEOs) at all levels, ranging from on-the-ground officers to top-level personnel involved in matters of national security. We offer real-time intelligence to counter threats from across the ideological landscape to protect public safety. Our team includes former LEOs who combine a deep understanding of law enforcement systems with subject matter expertise.

Threat detection, research and analysis

Support for LEOs includes real-time threat detection for key stakeholders and coordination with security providers. We equip law enforcement with the insights needed to meet the challenges of an increasingly complex threat environment.

Training and capacity building

We provide tailored trainings for LEOs and help develop their internal capabilities to understand and address the ever-changing threat landscape. We also offer advisory support for law enforcement and other government agencies facing threats against their own institutions or personnel.
