Controls access per user and per tag rather than relying on DCOM security alone, closing the gaps in distributed OPC architectures.
Matrikon OPC Security Gateway secures real-time OPC architectures end to end. Unlike solutions that rely only on DCOM security, it controls who can browse, add, read and write a tag on a per-user, per-tag basis on any OPC DA server. It implements the OPC Foundation's OPC Security specification for standards-based compliance, and the same protection applies to compliant third-party servers. HDA support extends coverage to historical data servers, and applying it together with the data encryption of Matrikon OPC Tunneller is the strongest way to harden a distributed OPC architecture.
Control that reaches down to the individual tag, where DCOM permissions could not.
Specify exactly which users may browse, add, read or write each tag, controlling access at individual granularity.
Moves past the limits of relying on DCOM configuration alone by applying security directly at the OPC layer.
Implements the OPC Foundation's OPC Security specification, enforces role-based security and leverages existing Windows security.
Compatible with all OPC DA clients and servers regardless of vendor — including clients that do not support the OPC Security specification. Existing systems can be secured without going offline, and OPC servers stay hidden from unauthorized users.
Extends protection to historical data servers, supporting Read Raw, Read Processed and Insert operations.
Applied together with the data encryption of Matrikon OPC Tunneller, it forms the strongest configuration for distributed OPC architectures.
