The افزونه امنیتی بازار سرمایه (Security Extension for Capital Market) is a Chrome add-on developed by مرکز آپا دانشگاه سمنان (Semnan CSIRT) with the aim of identifying fake portals of capital market brokers. It provides validation based on saving the address of the legitimate portal on the server and alerts the user with a warning if a fake portal is detected.

The extension features user-friendly interfaces that allow both ordinary users and experienced system members to easily meet their needs without requiring additional knowledge. By simply installing the extension on their browser, users can automatically initiate the validation and identification process for the legitimate capital market portal, distinguishing it from counterfeit ones.
