Empowering Smart Infrastructure with Secure and Resilient OT Networks
Operational Technology (OT) networks are the foundation of smart buildings and industrial environments. From energy management to real-time automation, OT systems connect the physical and digital worlds, driving efficiency, safety, and sustainability.
What is Operational Technology?
OT refers to the hardware and software systems that monitor and control physical processes. These include:
- SCADA systems
- Programmable Logic Controllers (PLCs)
- Building Management Systems (BMS)
In smart buildings, OT networks enable real-time operations, automation, and energy optimisation, making them essential to modern infrastructure.
OT vs IT: Key Differences
Feature
Architecture
Protocols
Priorities
Usage
OT Networks
Device-centric, often legacy systems
Modbus, BACnet (low security)
Availability, safety, uptime
Real-time control of physical systems
OT Networks
Device-centric, often legacy systems
HTTPS, TCP/IP (secure by design)
Confidentiality, integrity, agility
Data processing, communication, business apps
OT networks are built for long-term stability, often running for decades without major updates, making security and integration uniquely challenging.
Securing OT Networks in Smart Buildings
OT environments require a tailored security approach:
Asset Visibility
Know what’s connected and where
Patch Management
Address vulnerabilities in legacy systems
Network Segmentation
Isolate critical systems from external threats
Vendor Access Control
Monitor and limit third-party access
Traditional IT security practices can disrupt OT systems. Instead, we use non-invasive, OT-aware assessments to protect uptime and safety.
