Signal vs TeleMessage

Signal uses an advanced end to end encryption protocol that provides privacy for every message every time.

Signal is free and open source software, enabling anyone to verify its security by auditing the code. It's the only private messenger that uses open source, peer-reviewed cryptographic protocols to keep your messages safe.

Signal can be your default SMS/MMS text messenger. Encryption is not possible when sending SMS to your contacts, however.

Signal supports: emoji, pictures, videos, audio, contacts, any location and GIF.

Edward Snowden uses this messenger and recommends it to everyone who is concerned about his privacy.

Signal Desktop is a Chrome extension that allows you to mirror messages from your phone, including replying.

You can easily view all media shared in the chat without scrolling back to when it was shared.

Allows you to "send: messages to yourself and sync to desktop so you can use Signal as a kind of encrypted Pushbullet alternative

Unlike most messenger apps, Signal works reliably in all countries by securely circumventing internet censorship.

The sender credentials can be encrypted with the rest of the message, leaving only the recipient address readable by the Signal server. Even if Signal wanted they couldn't see who is talking with who by this mean.

They've been in the messaging business for over 15 years. Not a start-up, and use carrier-grade infrastructure.

They offer a bunch of APIs that you can integrate with own apps to automate messaging.

While the solution includes an app, messages can also be sent from a computer or Outlook. It can send data messages, text messages, voice messages, etc (as long as there are enough message credits).

An organization's mobile messaging can be managed by an administrator. That means admins can add, delete or suspend users and enforce messaging policies.

TeleMessage uses end-to-end encryption, with an additional encryption layer while data is in transit. It also offers a bunch of other security features such as PIN lock, time limited messaging and forward locking.
