OT Network Segmentation & Security Architecture Design

OT Network Segmentation & Security Architecture Design
At Danguard.net, we know that protecting industrial systems requires more than basic cybersecurity—it demands smart design. Our OT Network Segmentation & Security Architecture Design services ensure your operational technology (OT) and information technology (IT) environments are built to resist attacks, minimize risks, and keep critical operations running. Below, we explain how we tailor solutions for OT and IT, with a focus on OT’s unique needs.

OT Network Segmentation & Security Design

Operational Technology (OT) networks control physical processes—like factory machinery, power plants, or water treatment systems. These systems are high-value targets for cyberattacks, and poor network design can lead to catastrophic downtime, safety hazards, or data breaches.

What We Do for OT:

Network Segmentation: Divide your OT network into isolated zones to contain threats. For example, separate production lines from administrative systems to prevent malware from spreading.
Secure Architecture Design: Build OT networks with security in mind—using firewalls, unidirectional gateways, and industrial DMZs to block unauthorized access.
Legacy System Protection: Safeguard older OT devices that can’t be patched or updated, using compensating controls like traffic monitoring.
Risk-Based Zones: Group devices by criticality (e.g., safety systems vs. non-essential sensors) to prioritize protection.

Key OT Security Principles:

“Secure by Design”: Embed security into every layer of your architecture, not as an afterthought.
Least Privilege Access: Restrict user and device permissions to only what’s necessary.
Continuous Monitoring: Detect anomalies in real time with OT-friendly tools.

Why OT Needs Specialized Segmentation:
OT networks often lack built-in security features and run 24/7, making them hard to patch. Proper segmentation and architecture reduce the risk of a single breach crippling your entire operation.

IT Network Segmentation & Security

While IT systems differ from OT, they still require robust segmentation to protect data and prevent breaches.

Our IT Security Approach Includes:

Network Zoning: Separate sensitive data (e.g., customer info, financial records) from general traffic using VLANs or micro-segmentation.
Cloud & Hybrid Security: Secure connections between on-site IT systems and cloud platforms.
Endpoint Protection: Isolate high-risk devices (like employee laptops) to limit attack spread.
