Network Segmentation for OT Environments
Flat" networks carry a high risk. Netfosys applies intentional segmentation to reduce the attack surface, isolate mission-critical systems, and enhance the overall cyber resilience of your environment
Why Network Segmentation Matters
If there is a compromised endpoint in a flat OT network, attackers can move laterally without restriction - potentially disrupting operations or activating ransomware. Proper segmentation will provide an extra layer of protection and help you comply with regulations
What We Offer
Netfosys develops industrial networks with distinct zoning and secure conduits that are meant for effective OT environments and are mindful of operational impact
Purdue-aligned zoning
We develop layered segmentation that valuable aligns with the Purdue Model Levels 0-5 to help in separating critical OT away from IT systems
Secure zones and conduits
OT zones that are separated by firewalls, VLANs, or data diodes means that we build industrial zones that have all data flows controlled and auditable
Micro segmentation
Micro segmentation allows for asset level isolation within critical zones to not allow for lateral misuse of guest access even when there are segmented layers of security active
Protocol aware filtering
Protocol level filtering represents the most granular policy enforcement for known OT protocols including Modbus, OPC UA, DNP3, and PLC communication
IT/OT DMZ
Also known as "demilitarized zones", industrial DMZs allow for secure staging and migration processes for IT outbound to OT inbound, but fundamentally protects the OT environment from being compromised
