Signal

New features are continually developed for the secure messaging service Signal. The app is knows for its focus on privacy, with end-to-end encryption powered by the open source Signal Protocol. Every message and call is protected from view, except on the intended receiver's device. Android users have had a built-in backup feature for some time.

Online privacy and security is a constant concern that continues to grow and evolve with new technologies and policies. The government clearly aligns with big business on privacy issues, as evidenced by the recent repeal of the FCC privacy rules that would block ISPs from selling their customers' data without consent. While many turn to VPNs to bolster their online privacy, there are still concerns over call and message privacy.
