Cyber & Physical Security

In today's connected infrastructure landscape, the line between physical and cyber threats has blurred. Transit networks, airports, correctional facilities, smart buildings, and energy systems are all increasingly vulnerable—not just to physical breaches, but to cyber-attacks targeting OT environments. 

At Tandem Systems Group (TSG), we take a unified approach to security. Our integrated solutions protect both the physical perimeter and the digital core of your infrastructure—ensuring safety, uptime, and compliance across your entire operation.

TSG designs and deploys layered security systems that prevent unauthorized access, detect intrusion, and support real-time situational awareness. These solutions are tailored for environments with high foot traffic, critical assets, and strict regulatory requirements.  

 All components are fully integrated and tested as part of our systems commissioning workflows to ensure readiness from day one. 

• CCTV & Video Management Systems (VMS): High-definition surveillance with intelligent search and recording.
• Access Control Systems: Biometric, RFID, and smart card access management integrated with building systems.
• LiDAR & Smart Sensors: For perimeter protection, flow monitoring, and object classification.
• Fence & Perimeter Intrusion Detection (FIDS / PIDS): Detect and respond to boundary breaches in real time.
• Unified Security Platforms (PSIM): Integrate access control, video, alarms, and analytics into a single command center view.
• Emergency Intercom Systems: Two-way voice systems for secure zones, elevators, and restricted areas.

 OT systems are uniquely vulnerable—often isolated from IT oversight but controlling critical infrastructure like SCADA, HVAC, CCTV, and access control. Our cybersecurity services are designed to protect these environments without disrupting operations. 

 We secure both greenfield and brownfield environments, layering protection onto existing infrastructure with minimal system downtime. 

• Asset Discovery & Network Mapping
• Threat Detection & Anomaly Monitoring
• Firewall Deployment & Rule Optimization
• Endpoint Security & Patch Management
• Zero-Trust Secure Remote Access (Jump Servers)
• Intrusion Detection / Intrusion Prevention (IDS/IPS)

 Security isn’t just a product—it’s a process. TSG offers consulting and technical services to help organizations develop, document, and maintain their cybersecurity programs.  

We meet you where you are—whether you're starting from scratch or maturing an existing program
