Many people are looking for encrypted messaging apps to communicate with their coworkers, friends, and family safely. While there are other ways to protect your data, end-to-end encryption has become a standard security feature in both consumer and business messaging apps.

🗝️ Find out what are the best encrypted messaging apps today, how encryption works, and how else you can ensure highest security standards while texting.

What are encrypted messaging apps

As their name says, encrypted messaging apps are solutions that support the transmission of encrypted data. Encryption ensures that the only parties that can access the message content are the ones that hold the decryption keys – usually the sender and the receiver.

Therefore, encrypted messaging apps are enforcing one of the most popular and high-standard data protection protocols. Although many people know about encryption through their private messaging providers, it is also one of the most frequently used data protection protocols in business messaging apps.

Moreover, the need for safe communication and encrypted messaging apps only increased with the abrupt adoption of hybrid work policies. As such, encrypted messaging apps are now a norm in digital workplaces around the world. For example, more than 50% of IT leaders say that mitigating cybersecurity risks is their priority when it comes to digital transformation.

How do encrypted messaging apps work

As described above, encrypted messaging apps use the process of encoding information to prevent anybody viewing the content of them. As data privacy is becoming an increasingly important topic, end-to-end encryption became known as a standard data protection protocol.

However, end-to-end encryption does not equal data privacy and protection. Yes, it does prevent the message from being read if intercepted, but encrypted messaging apps ensure that messages are encrypted only in transit.

What does that mean? This means that the provider of the service can still access the data and read the data – unless they say they don’t. Some encrypted messaging apps explicitly say they don’t store data nor metadata on their servers, or sell them to third parties.

Moreover, encrypted messaging apps cannot guarantee data protection if endpoints are compromised. This is why there are many new technologies and initiatives aimed at increasing endpoint security.

In any case, encrypted messaging apps are becoming the standard when it comes to safe communication. Communication industry is the leader when it comes to using encryption, but 60% of employees say their organizations transfer confidential data to the cloud whether or not it is encrypted.
