If you feel pain in configuring DCOM between OPC Client and Server, or can't harden your wrapper class due to no access to source code, you really check this solution out.

Simply put this solution can help you retrieve OPC DA/AE/HDA data back without worry using DCOM or DCOM hardening. So it is future-proof for any future Microsoft DCOM vulnerability. Architecturally it is designed to work in such a modern way so you can pick up your favorite language（C/C#/Java/JavaScript/Python/Swift）and receive data in your familiar JSON format. No gateway service installation required and support cross-platform in various clients (desktop/mobile/cloud/edge). Hope it can help protect your investment in Classic OPC for a long time to come.
