Top 4 secure messaging apps for smartphones

It’s impossible to overestimate the importance of security when it comes to business. While most businesses do a good job of securing their premises, teaching employees to use secure passwords, and employing other cybersecurity techniques, most companies forget to secure their communications. Using encrypted and secure messengers for all business-related communications can help protect information related to your customers, employees, contractors, and suppliers. To ensure that nobody except for the sender and recipient of the message can read its contents, it’s best to use a messaging app secured with end-to-end encryption. Here’s an overview of the best encrypted messaging apps:

Signal Private Messenger

This app is the top choice of all cybersecurity experts. This is because the messenger’s code is open source. This means anyone can examine it to make sure that it really is encrypted and secure, which many cybersecurity experts have done. The app is free to use and it’s available on iOS, Android, as as a browser plugin on computers.


If your company still uses Blackberry phones, consider trying Silent. This app costs just $10 per month and it allows users to send and receive messages and files securely, make encrypted voice and video calls, and send messages that disappear after a set amount of time.


With over 500 million monthly active users, this is one of the most popular apps for secure messaging for business and personal matters. The app supports encrypted voice calls, as well as text and voice messages. It also allows users to share files, photos, videos, and location data.


WhatsApp is one of the most popular messaging apps in the world. In 2016, the app was updated to offer end-to-end encryption of text messages, photo and video files, and voice messages.
