Packet capture can be used to fulfill a warrant from a [[law enforcement agency]] to [[wiretap]] all network traffic generated by an individual. [[Internet service provider]]sproviders and [[VoIP]] providers in the United States must comply with [[Communications Assistance for Law Enforcement Act]] regulations. Using packet capture and storage, telecommunications carriers can provide the legally required secure and separate access to targeted network traffic and can use the same device for internal security purposes. Collecting data from a carrier system without a warrant is illegal due to laws about interception. By using [[end-to-end encryption]], communications can be kept confidential from telecommunication carriers and legal authorities.<!--[[User:Kvng/RTH]]-->
