On-Site Security Guards & Asset Protection
We deploy professional on-site security officers to safeguard commercial properties, business facilities, and data centers. Our security guards excel in observation, de-escalation, and conflict resolution, serving as a deterrent against theft, vandalism, and unauthorized entry. For data centers and technology facilities, we establish layered physical security, single-point entry protocols, granular door control, and reception security to isolate intruders and secure sensitive equipment and data.
Construction Site Security
Construction sites face frequent challenges from material theft, tool loss, and trespassing liabilities. We protect active building sites using on-site security officers combined with self-powered camera systems. These self-contained surveillance units require no cabling, capture time-lapse photography, upload footage directly to cloud storage for remote monitoring, and can be easily repositioned as site requirements change.
Active Shooter Training & Risk Consulting
Through Harmon Risk Consultation, we offer active shooter training, crisis management, and proactive intelligence gathering. Our 24/7 analysts evaluate specific organizational threats, conduct risk assessments, and deliver specialized training programs to build resilience and prepare staff to react effectively during emergency situations in high-risk or crowded environments.
Video Surveillance & Hybrid Security
We design cost-saving hybrid security options that pair strategic CCTV video surveillance with physical officer patrols. By positioning digital cameras across strategic access points and archiving footage for investigation, we deliver continuous monitoring and complete asset protection tailored to your commercial facility.
