How We Secure Charleston
Unique Charleston Security Challenges
The Charleston metro area—including Charleston, North Charleston, Mount Pleasant, Summerville, Goose Creek, and surrounding Lowcountry communities—presents a security environment shaped by port operations, tourism, military installations, and rapid residential growth. As one of the Southeast’s fastest-growing coastal regions, Charleston requires security programs that balance public accessibility with protection of high-value assets and critical infrastructure.
- Port & Maritime Operations: The Port of Charleston and surrounding industrial zones face risks related to cargo theft, unauthorized access, perimeter breaches, and supply-chain disruption.
- Tourism & Hospitality Density: Historic downtown Charleston, hotels, resorts, beaches, and entertainment districts experience heavy visitor traffic, increasing theft, disorderly conduct, and crowd-management challenges.
- Military & Defense Presence: Joint Base Charleston drives heightened security expectations for adjacent commercial properties, contractors, housing, and logistics operations.
- Property & Vehicle Crime: Retail centers, parking garages, and multifamily communities face ongoing issues with vehicle break-ins, trespassing, and after-hours incidents.
- Multifamily & Suburban Expansion: Rapid growth in Mount Pleasant, Summerville, and North Charleston creates security gaps around access control, parking enforcement, and nuisance behavior.
- Industrial & Logistics Corridors: Warehouses, rail-adjacent properties, and trucking routes near the port require perimeter security and overnight protection.
- Construction & Development Activity: Continuous residential and commercial development increases vulnerability to equipment theft, vandalism, and unsecured job sites.
- Weather & Coastal Risk: Hurricanes, flooding, and storm surge create additional exposure during evacuations, closures, and post-storm recovery periods.
- Liability & Duty-of-Care Pressure: Property owners must demonstrate documented security programs and proactive risk mitigation to meet insurance and regulatory expectations.
