MatrikonOPC DMZ Agent™

Secure Data Access Across De-Militarized Zones



Download Datasheet

MatrikonOPC DMZ Agent™ provides a secure, standardized solution for accessing real-time and archived control automation data across De-Militarized Zones (DMZs) using off the shelf MatrikonOPC products.

Problem: Corporate IT departments implement DMZs to protect network assets by layering and isolating secure zones from those that are considered less secure. Network traffic is restricted between these layers via multiple firewalls and a common PC between them. While DMZs work to secure the automation environment from the dangers present in the outside world, they prevent necessary operations and business applications from accessing key data using traditional methods.

Solution: DMZ Agent™ overcomes DMZ related control data sharing issues by providing engineers and system integrators with two time-tested OPC architectures depending on design and corporate security policies.

  • The DMZ Agent Pull solution enables permitted enterprise applications to     securely initiate requests for OPC data located within a secure network.


  • The DMZ Agent Push solution allows permitted enterprise applications to     receive secure network data pushed from within a DMZ (one way firewall     configuration).

  • Enabling Technologies

  • MatrikonOPC Tunneling Technology
        Matrikon OPC Tunneller provides an easy, reliable and effective way to
        communicate between networked computers. It does away with the headaches
        typically associated with the configuration of DCOM. No longer are different
        protocols, security settings or locations a factor when sharing data between
        computers. This is achieved by simply installing Matrikon OPC Tunneller on
        the OPC client and OPC server nodes. From that point it is only a matter of
        stipulating a computer name or IP address and the port setting. Learn more!

  • MatrikonOPC Security Gateway
        MatrikonOPC Security Gateway secures all real-time OPC architectures. Unlike     OPC solutions that rely only on DCOM security, Security Gateway controls who     can browse, add, read and/or write to a tag on a per-user-per tag basis on any     OPC DA server. Fully standards-based for maximum compatibility, the Security     Gateway implements the OPC Foundation’s OPC Security specification.

  • MatrikonOPC HistoryLink
        The MatrikonOPC HistoryLink is built upon the MatrikonOPC Tunnelling
        technology. HistoryLink enables two OPC HDA capable process historians to
        share historical data. HistoryLink can move data on an ongoing schedule
        (ScheduleLink), or be triggered via some process variable (MonitorLink).
        Historical data management has never been easier. HistoryLink is also iC!
        Enabled, thus remote configuration is possible. Learn more!

  • MatrikonOPC Buffer
        MatrikonOPC Buffer is an off the shelf solution for remote data collection,
        buffering, and with the optional History-Link module; historical data transfer
        to a central process historian. This product is great for engineers and project
        managers who need guaranteed data collection and delivery from
        geographically remote sites. Learn more!

  • MatrikonOPC UA Proxy
        The MatrikonOPC UA Proxy enables existing OPC Classic client applications to     connect and communication with Unified Architecture (UA) servers and devices.     This allows users to integrate emerging UA products into existing OPC Classic     infrastructure. Learn more!

  • MatrikonOPC UA Wrapper
        The MatrikonOPC UA Wrapper for COM OPC Servers provides OPC UA clients     with access to legacy COM OPC DA and HDA, OPC Servers using OPC UA     Specifications. The UA Wrapper exposes COM OPC servers as folders in the     OPC UA server’s address space. Learn more!
