Telegram is a cross-platform messaging service that has a focus on speed and security. The messaging platform is supported by the founders of Russia's biggest social networking platform, VKontakte. Standing out in such a crowded space can be difficult, and with existing messaging giants like Whatsapp and Line, Telegram had to act on its promise of being more secure.

The app uses two layers of secure encryption based on 256-bit symmetric AES encryption, RSA 2048 encryption and Diffie–Hellman secure key exchange, in an effort to keep all of your information as safe as possible. Unlike other messaging platforms, Telegram is a non-profit operation, and has committed to remaining completely free for users. This means, no ads, no subscription cost, just revenue from investors. If the time comes where it has run out of money, the company plans to ask users to donate, or add extra options — beyond what is already available — that users can opt to purchase.

Telegram officially launched on the Windows Phone platform back in May 2014, and since then has seen a number of updates. The messenger has added voice messages, Photo Hub integration, document and video sharing, self-destructing messages and much more since its initial release.
