Protecting Our Nation’s Most Vulnerable Spaces

Established at Northeastern University in 2021, the Soft Target Engineering to Neutralize the Threat Reality (SENTRY) Department of Homeland Security Center of Excellence addresses the many challenges of protecting soft targets and crowded places in our homeland.

SENTRY SUCCESSES

A Homeland Security Center of Excellence

The Department of Homeland Security Centers of Excellence bring together leading experts and researchers to conduct multidisciplinary research and workforce development for homeland security solutions. Authorized by Congress and chosen by the Department’s Science & Technology Directorate, each center is led by a university in collaboration with partners from other institutions, agencies, laboratories, and the private sector.

ABOUT DHS COES
