Signal vs. Telegram: What s the Difference?

Signal and Telegram are both reliable and secure messaging apps. Neither app is owned by a major tech company. Signal is managed by Open Whisper Systems, a non-profit organization.

Security and Privacy

In terms of security and privacy, Signal is your best bet. All signal messages are, by default, end-to-end encrypted, which means no third party can access your conversations. In comparison, Telegram expands the data shared limit, which leaves other messages to be potentially visible to other third parties, as end-to-end encryption is done to messages in the secret chat option only.

Signal s encryption protocol (formerly known as the TextSecure protocol) is open-source and available for anyone to see and examine, meaning any security flaws can be quickly identified and fixed. Telegram uses MTP 2.0 protocol, an upgrade from MTProto 1.0, to encrypt its secret chat option messages, which is open-source on the client side. Telegram s encryption method, through security experts, is said to have more limited track records than Signal. This results from the latest protocol being more secure than the MTProto 1.0 version.

Also, Signal collects less data on users than Telegram. Signal only stores the date and the phone number used to sign up, as well as your last connection time. Comparably, Telegram s metadata provides your IP address which links to your location, who you are in contact with, and when.


Signal and Telegram both support the most popular platforms, including Linux, Windows, MacOS, iOS, and Android. They also offer a Chrome browser extension to allow web-based access.

Also, Telegram supports Windows OS and allows universal access to unencrypted messages through a website access portal from the servers. It is worth noting that Telegram s secret chat option is available only through the mobile application and not through web-browser access.

A notable difference between Signal and Telegram is that Signal service depends onGoogleservices for notifications. Practically, this only applies to devices with custom Android OS.

Usability and Installation

Both Signal and Telegram are relatively easy to use and install. Download the software through the platform of your choice, and you ll only need to sign up using your phone number and verify using an SMS or a call with a code in the case of Telegram.

In both services, you can anonymously configure your account if necessary. Telegram has detailed options to set up for user experiences, such as themes and colors, whereas Signal has similar but basic ones. This makes Signal an easy app to use and set up.

Telegram focuses more onsocial mediamessaging and broadcasting, while Signal focuses on secure messaging. Telegram supports sending uncompressed images, making it a better messaging app when compared to Signal for sharing photos. However, Signal has a face-blur feature installed by default for use when sending images.

In terms of support, both apps rely on online help or a volunteer to address specific issues, as they both operate on a non-commercial basis. Signal has the upper hand in providing a more secure messaging app, as it also supports visually impaired users.

User Experience

You can customize Telegram to enhance the user experience by adjusting several settings, from themes, font sizes, colors, emojis, animations, and notifications. The app can create a playlist when sent a list of songs and launch them in its in-built media player. You also can conduct surveys and quizzes, edit images and videos, and view other individuals within your proximity with the People Nearby feature (though it may raise privacy concerns).

On the other hand, Signal is a simple application that has a focus on sending text, audio, and video messages securely. Recently, Signal has introduced animated stickers as part of its available emojis. Comparably, Signal is easy to use and requires minimal customization for a top-notch user experience.

Data Storage

Unless the secret chat option is enabled, Telegram collects and stores its messages in a cloud-based platform. Telegram claims to store its data across distributed databases, and the encryption keys are stored in the server, thus allowing them to decrypt messages. Similarly, if Telegram is a target for attack, the rival can access all user data, including chat information. This makes Telegram a threat to companies that actively archive messages with intentions to meet mobile company compliance.


Signal wins on privacy and security due to its robust encryption measures. However, we need to find out which messaging app is better for users operating within the confines of mobile compliance guidelines.

Telegram offers optional end-to-end encryption and protects messages only in the secret chat option. Consequently, users communications on Telegram remain vulnerable to cyber threats in unsecured environments. Contrary, Signal, by default, offers end-to-end encryption, making it a more secure option for your communications. For companies running in highly regulated sectors, such as banking and finance, education, healthcare, and pharmaceuticals, encryption in messaging is crucial for mobile compliance.

Therefore, it s recommended that businesses use Signal to Telegram. However, this practice becomes effective in enterprise messaging solutions and when companies archive text messages. Regardless of the platform you are using, companies must emphasize the coverage of all communications between employees and stakeholders to maintain mobile compliance.
