Systems and methods for website and application monitoring and testing inside from a private network are presented. An agent module resident on an agent device inside the secured network periodically sends an HTTP message to a controller server and receives an HTTP response. The agent module parses out a set of instructions from the content of the HTTP response and executes the instructions. The agent module collects and compiles responsive information resulting from the instructions being executed and sends the compiled information to the controller server for storage and reporting.
