The Security Office is an office under the General Services Office tasked to ensure the safety and security of the Lasallian community within De La Salle University-Dasmariñas.
It also actively initiates measures to complement the University's disaster risk reduction management efforts. In 2017, the University deployed a emergency response vehicle and medical first responders as well as stationed a fire truck at the motor pool for quick response in the event of natural disasters and emergencies.
DLSU-D also embarked on the deployment of a K9 unit to patrol the university and installed walk-through metal detectors at Magdalo and Madiwang Gates.
