OT Security & IT–OT Segmentation
Protect production systems while keeping a clear, controlled boundary between IT and operational technology.
Explore the scopeA CLEAR BOUNDARY
One business. Two different operating rhythms.
Business systems need frequent updates, while production equipment follows different maintenance and downtime constraints. A controlled boundary keeps essential connections in place, and ongoing monitoring helps identify traffic that no longer needs to cross it.
IT–OTControlled connection
- Approved data flows
- Firewall & ongoing monitoring
OT network
- Production machines and controllers
- Limited, planned maintenance windows
- Operational continuity and safety first
ABOUT THIS SERVICEBack to all services in this area
OT Security & IT–OT Segmentation
Production equipment often stays in service for years. Its controllers and software may be difficult to update because a change requires vendor validation, carries a cost, or means stopping machines and interrupting work. When these systems share unrestricted access with the regularly updated IT network, an incident in either environment can spread across the other. OT security addresses this exposure while respecting the availability and safety needs of production.
A practical boundary between IT and OT
We assess production assets, data flows and the connections required by operators, vendors and business systems. We then design separate network zones and controlled paths between them, using firewall policies, access rules and monitoring that suit the site. The objective is to let essential information move without giving either network unrestricted reach into the other.
Monitoring after segmentation
The work continues after the boundary goes live. Together with the client’s network administrator, SITEC monitors traffic crossing between IT and OT, reviews the connections against the agreed rules and investigates flows that are unnecessary or unexpected. This ongoing visibility helps keep the permitted paths aligned with real production needs as the environment changes.
Firewalls chosen for the environment
Depending on the existing infrastructure and operational requirements, we can implement the separation with FortiGate, Sophos, SonicWall or Palo Alto Networks firewalls. We coordinate policy changes and validation with the production team so protection is introduced without overlooking the connections on which the machines depend.
Experience on factory floors
SITEC brings long-standing hands-on experience applying IT–OT separation in more than one factory. We shape the design around actual production constraints, including equipment that cannot be stopped or patched on a routine IT schedule, and work with the site team on a phased implementation.
