Around 2000, to address safety concerns both on and off-campus, the university instituted a program where students are issued a portable alarm unit (PAL) that pinpoints their position and enables campus security to get to them in under two minutes. This system works immediately on the university campus, and in the neighborhood surrounding campus. Further, the Campus Security Department has 40 unarmed personnel that provide security services 24 hours a day, with both on-foot and on bicycle patrols. The university has received the Jeanne Clery Campus Safety Award for adopting technology and other initiatives to safeguard our students 24 hours a day. In 2018, in the midst of a rapid gentrification in the neighborhood surrounding the campus, the global security firm ADT ranked UB as the safest campus in Connecticut. In 2019, the University discontinued the use of PALs in favor of the LiveSafe app for mobile devices. Bridgeport's seal combines 4 core elements of its traditions and distinct character.
