Security on Messaging Apps

Security on Messaging Apps
Demi B | 15-03-21
Security on messaging apps is coming to the forefront of the tech industry as people begin using them for business transactions and even storing business data or essential work apps on their phone.
There are a lot of messaging apps in the market. Some people prefer to converse on messaging apps, as the back and forth of messages are much more real time compared to emails and more secure compared to SMS.

With the issues that came up about the security and privacy policy of WhatsApp, people have been turning to other messenger apps such as Signal and Telegram. Let us look at some of the security and privacy features of the three:


One of the biggest issues people have with this messaging app is the long list of data links, which is information that WhatsApp is allowed to retrieve from you. This app is also one of the first to offer end to end encryption in the market. This ensures that only the sender and recipient will be able to read the messages exchanged. This app is free and funded by Facebook. It is not open source, except for the end-to-end encryption.

In January 2020, Jeff Bezos, CEO of Amazon, was hacked through a WhatsApp video message. There was also an incident where a spyware vendor hacked 1,400 devices with software, that led to a lawsuit from Facebook.

Generally, WhatsApp presents more of privacy problems rather than security issues. WhatsApp is also available across different devices and platforms. Their chat backups are stored in the device and messages are deleted on their own after some time.


This messaging platform only takes about four linked data from users, which include names, phone numbers and contacts. What is great about Telegram is it puts in the effort to have a social network kind of environment for users. It also has a sender to user encryption feature, but you must turn it on manually as it is not the default set up. 

A feature that Telegram offers that is not in most messaging apps is the “secret chats”, which has an extra layer of security. It notifies the sender if a screenshot of the conversation on secret chat was taken. It gets rid of the forwarding option. And you can set a time for each message to disappear after being read by the receiver.

Telegram has been exposed to many breaches from 2016. A massive breach was linked to Iran, which happened again in 2020. There was also a case where a deep fake (seemingly realistic edited photos and videos) bot created forged nudes of women that came from their regular photos.


Signal only collects user’s phone number for information. It is fully open-sourced. It sends fully encrypted messages, videos, images, and audio clips to individuals or a group. It also has app-specific locking features, onscreen privacy options, and even disappearing messages (much like Telegram’s secret chats).

Even with Signal’s superb security details, it will be useless if the person you send it to is not using Signal. It is available for windows, macOS, Linux, iOS, and Android.

One of its unique vanishing messages feature is the option to choose how long the message can be viewed before it is automatically deleted.
