Messaging firm Viber is adding end-to-end encryption for 711 million of its users, becoming the latest tech firm to embrace encryption on an massive scale. Making the move even more provocative is the fact Viber is owned by a Japanese conglomerate and operates out of Israel – making it immune to existing and any upcoming U.S. encryption laws.

Viber is not the first messaging company outside the U.S. to offer encryption, but it is the largest by a long shot, said Ed McAndrew, a cyber security attorney with the law firm Ballard Spahr and former federal cybercrime prosecutor.
