Mobile phones are so small that it's almost impossible to track a person conducting a conversation and to spot such misuse. C-Guard can eliminate this problem.
Many cellular phones dial the last number called by simply hitting the SND key.
In many instances, people press the SND key by mistake and thereby initiate a call unintentionally. Such incidents may lead to transmission of confidential information over the air and the party receiving the call may listen to the conversation taking place. With C-Guard, these accidents will no longer happen. Various cellular protocols enable a skilled technician to remotely activate a specific cellular phone as a bugging device and listen to all conversations taking place in the vicinity of the cellular phone's microphone. C-Guard easily prevents this.
