With mobile phones and computers always connected, digital communication is now the norm. This has made security and privacy more important than ever, as cybersecurity threats continue to grow.
For those who prioritize private and secure messaging, Signal and Telegram are two of the most popular choices. The debate between them mainly revolves around differences in security, data handling, features, and usability. We’ll analyze each app’s strengths and weaknesses, focusing on security and transparency, so you can make an informed choice.
Signal and Telegram are popular privacy-focused alternatives to WhatsApp and Facebook Messenger. Telegram offers more features and cloud storage, while Signal is simpler, more transparent, and highly secure. But which app is better at keeping personal data safe?
Safety and Security
Signal and Telegram are among the most secure messaging apps. They are praised for their strong privacy and security features, making them top choices for safe communication. The Signal vs Telegram debate comes down to key differences in ease of use, data handling, and security. In this article, we compare both apps’ security, pros, and cons to help you make an informed decision.
What is Signal?
The Signal Foundation, a non-profit organization, created the Signal messaging and communication app. The app prioritizes privacy, encrypting all messages, calls, and media by default. Known for its humble design and strong security, it uses the Signal Protocol—an open encryption system also used by WhatsApp.
Main Features of Signal:
- End-to-End Encryption: Signal encrypts all communications by default so only the receiver and sender can see the content.
- Minimal Data Retention: Signal doesn’t retain metadata but retains only the phone number you use to sign up for an account.
- Self-Destructing Messages: Users themselves can set timers for messages to disappear automatically, adding security.
- Open-Source Code: Signal’s codebase is fully open-source. Security professionals worldwide regularly audit it in order to detect potential vulnerabilities.
With its dedication to transparency and user privacy, Signal has become a go-to app for activists, journalists, and anyone prioritizing privacy and security in their communication.
What is Telegram?
Released by Pavel Durov in 2013, Telegram is a cloud messaging platform with configurable privacy features and great user experience. With over 700 million active users, Telegram stands out for its rich features, including file sharing and group chats for up to 200,000 members.
Key Features of Telegram:
- Multiple Chat Types: Telegram features standard cloud-based chats and end-to-end encrypted “Secret Chats.”
- MTProto Protocol: Telegram uses its own encryption protocol for cloud-storing messages, though not end-to-end by default.
- Cross-Platform Sync: Telegram’s cloud-syncing storage facilitates data across devices.
- Custom Features: Telegram provides features such as bots, channels, and rich customization options for user engagement.
Though Telegram users like it for its versatility, the security-conscious would be horrified at the cloud-based default system it has to provide.
Security Features Comparison: Telegram vs Signal
Encryption standards, privacy terms, and Signal’s message self-destruction enable us to compare its security with that of Telegram. We present you a detailed comparison below.
Encryption Standards
One-on-one messages, group chats, and voice/video chats – Signal employs end-to-end encryption (E2EE) by default. That means no third party – including Signal – gets to see the content of your communication. Signal’s encryption is powered by the Signal Protocol, known as the gold standard in cryptographic security.
Meanwhile Telegram’s cloud-based chats are encrypted by default with MTProto, protecting data in transit and at rest. E2EE is only offered through its optional “Secret Chats” feature. MTProto has been criticized for not being as open or battle-tested as Signal’s protocol, though it does offer strong encryption.
Verdict: Signal offers better encryption since E2EE is always enabled; Telegram requires opting into “Secret Chats” for the same protection.
Privacy and Data Collection
Signal treats privacy in a revolutionary manner. The app stores just your phone number for account registration and minimal information. Signal servers store no logs, metadata, or chat history, and the users have complete control over data.
Default Telegram chats store messages, media, and data in the cloud, and syncing to devices is easy. This is convenient for the users at the cost of Telegram gaining access to your data, which is encrypted.
Verdict: Signal stores data only on your device, making it the top choice for privacy-conscious users. Telegram’s cloud storage may raise concerns for those wary of third-party data access.
Self-Destructing Messages
Signal provides the feature of sending self-destructing messages in all chats. The feature is highly customizable, allowing users to set messages to expire anywhere from seconds to weeks.
Telegram permits self-destructive communications in its “Secret Chats.” Users can set timers from seconds to days, ensuring sensitive messages are automatically deleted after a set time. Normal cloud chats do not permit this functionality.
Verdict: Both applications are excellent at sending self-destructive messages, but Signal is a narrow victor since it can enable every chat.
Open Source and Transparency
Signal has an open-source codebase, allowing the public to inspect and audit its software. Such openness generates trust in users and enables security researchers to detect vulnerabilities early.
- Telegram is half open-source. Nonetheless, its server-side code and MTProto protocol are proprietary, limiting outside scrutiny despite its open client-side code.
- Signal’s commitment to open-source concepts makes it more open and believable than Telegram’s half-open concept.
Table of Comparisons: Signal vs Telegram Security Measures and Dynamics
| Feature | Signal | Telegram |
| Default Encryption | End-to-End Encryption (E2EE) | MTProto (Cloud Chats) |
| Optional E2EE | Enabled by Default | “Secret Chats” Only |
| Data Storage | On User Devices | In the Cloud |
| Self-Destructing Messages | Available in All Chats | “Secret Chats” Only |
| Open Source | Fully Open Source | Partially Open Source |
Signal vs Telegram: Which Messaging App Is More Secure?
Recent data shows that Signal is the most secure messaging app, thanks to its strong encryption, minimal data storage, and commitment to privacy. Its open-source design and default end-to-end encryption make it the gold standard for secure messaging.
Telegram, on the other hand, is more of a general-purpose app for users who value features like cloud sync, bots, and large group chats. However, due to its reliance on optional E2EE and cloud storage, it is not as appealing to privacy-focused consumers.
Who should use Signal?
- People who are looking for maximum security and privacy.
- Professionals working with sensitive materials, activists, and journalists.
Who should use Telegram?
- People who are looking for feature-rich communication devices.
- Recreational users who prioritize absolute security second to convenience.
