Matrikon OPC Security Gateway secures 3rd party, real-time and historical, OPC Classic architectures. Unlike
regular OPC solutions, which provide coarse DCOM-based security, OSG offers granular control over who can
browse, add, read, and write to each OPC item on a per-user and per-tag basis on any OPC server.
OSG is based on the OPC Foundation’s OPC Security specification for maximum interoperability, making it an
open standards-based solution. Use OSG to transform your OPC architectures from a security liability to an
effective part of your defense-in-depth strategy.
