Best Messaging Apps for Privacy and Security

Most Secure Encrypted Messaging Apps

Messaging apps are an integral part of modern communication. They keep you in touch with everyone. No matter how far you live, you can easily contact your friends, family, or colleagues.

Though instant messaging apps have many benefits, security-concerned individuals question their promise to keep data safe.

The reason behind the dubiety is the lack of security. Many messaging apps are not secure. Such applications need encryption to hide end-to-end communication.

The encrypted messaging apps are important because of many reasons. For example, marketing companies are increasingly growing and constantly invading users’ privacy. These companies keep accessing users’ chat history.

The main aim is to inspect users’ communication to know their buying interests. Later, these marketing agencies launch targeted marketing campaigns using your data. Therefore, encryption technology is crucial to conceal your data from marketing agents and other prying eyes.

Besides that, some old and new messaging apps save chatting sessions on their server. If a server gets hacked, it publicly exposes the entire chat history.

The only way to keep data privacy intact is through end-to-end encryption. Privacy advocates advise on using the best encrypted messaging apps.

End-to-end encryption allows only the recipient to read the intended message. It means that no middle-man or intruder can invade communication. Therefore, iProVPN is featuring a list of the best messaging apps for privacy and security to try in 2021.

The Best Encrypted Instant Messaging Apps 2021


Telegram comes top on the list of the most secure encrypted messaging apps. With the arrival of 2021, the new privacy policy of the giant messaging app “Whatsapp” disappointed millions of its users. Telegram then came as the best Whatsapp alternative, and many people installed this end-to-end encrypted messaging app.

Telegram messaging app has a slicker interface, and exciting options like chat backup and message disappear feature.

You can set dates for message expiration. Besides that, Telegram also lets you enjoy video calls and group chats.

The only catch is that its end-to-end encryption is not activated by default. Meaning, you and your recipient have to enable encryption to make use of it. In addition, it’s not an open-source app, so no security expert can audit it.


Signal is another most trending secure messaging app. Unlike Telegram, Signal is an open-source messenger that allows security experts to check and update security.

The app’s interface is simple without fancy visuals and graphics. However, it supports all the popular features, including file and photo sharing, group chats, and video calls. 

Signal is also a good alternative for the default SMS app, but we will not advise you to switch the SMS app with Signal. The basic SMS is not protected with encryption. Hence, switching SMS with Signal doesn’t seem like a good idea.

You and your recipient must have Signal installed for end-to-end encryption; otherwise, it will not work the way you want in terms of encryption and security. What’s more? Signal also has a cool feature that automatically disappears your unwanted chat records.


iMessage is the most secure messaging app for iPhone, iPad, and macOS. In terms of features, iMessage doesn’t offer end-to-end encryption only; it also has other enticing features that include AR-based Animoji, Memoji stickers, and on top of everything, a simple user-interface. 

Another top quality of this app is that it allows you to easily add videos from YouTube, Spotify links, videos, photos, and other media forms.

However, iMessage is only available for Apple devices. Since the app is only available for Apple devices, the backup message option is accessible with iCloud. Apple manages the iCloud encryption key, so if your accounts get compromised or hacked, then it might risk your data privacy.


Silence gets you ultimate protection for texts with its powerful encryption support. If you’re looking for the best private messaging app, then relying on Silence won’t let you down.

The app uses Axolotl encryption protection to cover security needs. The best thing is that if your recipient doesn’t have the app, you can still use Silence as a normal SMS application.

Also, the app needs no internet connection to function. It can work without sign-up and server involvement. In addition, Silence is an open source app, so updating security patches is also easy.


Threema doesn’t only protect your texts; it’s a secure messaging app for calls too. Other secure chat messengers protect connection security.  Threema goes the extra mile and ensures security by not saving contact details on its servers.

The data automatically deletes once it reaches the destination. It means that you can only have local files on your phone rather than storing files on third-party servers where anyone can hack or collect sensitive data.

Threema is a secure multi-tasking app that enables you to create chat groups, send files and images. Moreover, you can also create polls to know the views of your friends on anything particular. On top of security, the app never asks you for email or other sensitive information to sign in.


There you have it! The list of the best messaging apps for privacy and security 2021 comes to an end. On the subject encryption, iProVPN’s encryption gives you protection over public Wi-Fi and prevents activity monitoring by the ISP.
