Provided are methods, including computer-implemented methods or methods implemented by a network device, devices including network devices, and computer-program products for an active deception system. The active deception system can separate execution of services from deception mechanisms on a network. In particular, the active deception system can include a sensor on the network. The sensor can establish a two-way connection with a remote server executing the services. The sensor can receive communications from client devices and forward the communications to the remote server. While this forward can happen, the client devices might not be aware of the forward. In fact, the client device might only be aware that the sensor receives a communication and responds to the communication.
