Transportation security stretches well beyond screening weary air travelers. TSA's security inspectors work to enforce security guidelines developed in collaboration with both private and public sector experts. They are in U.S. communityiesat the local airport, cargo hub or harbor tirelessly watching over facilities and operators to ensure there is no gap in the fence.

Through the Surface Transportation Security Inspection Program, TSA has deployed 100 inspectors, assigned to 18 field offices across the country. These inspectors provide support to our nation’s largest mass transit systems, and perform frequent inspections of key facilities including stations and terminals for suspicious or unattended items, among others potential threats. Inspectors are actively engaged in performing Security Analysis and Action Programs, which constitute a systematic examination of a stakeholder’s operations to assess compliance with security requirements, identify security gaps, develop best practices, and gather information on the system, its operations, and its security resources and initiatives.
