Signal vs Telegram in 2025: Which Messaging App is Truly Private & Secure?

With rising cyber threats and government surveillance, picking a secure messaging app is critical. Signal and Telegram lead the privacy debate, but their security models differ drastically. Lets break down “Signal vs Telegram in 2025: Which Messaging App is Truly Private & Secure? “

🔍 Key questions answered:

• Does Telegram have end-to-end encryption? ( best when using private chat)
• Is Signal really the most private app? (Yes, and here’s why)
• Which one should you use in 2025?

1. Encryption Showdown: Signal’s E2EE vs Telegram’s “Secret Chats”

Signal: Unbreakable Encryption by Default

✅ All chats encrypted (1-on-1, groups, calls)
✅ Signal Protocol (used by WhatsApp, Skype, and Facebook Messenger in “private mode”)
✅ Post-quantum encryption (2025 update resists future hacking)

Telegram: Encryption Only If You Enable It

⚠️ No default E2EE (except “Secret Chats”)
⚠️ Cloud chats stored unencrypted (accessible to hackers or governments)
⚠️ MTProto protocol (criticized by cryptographers for potential flaws)

Winner: Signal (Telegram’s opt-in encryption is risky for most users).

2. Privacy: Who Sells Your Data?

Signal’s Privacy Perks

• No meta data stored (can’t see who you talk to or when)
• Anonymous usernames (2025 feature: no phone number needed)
• Non-profit, no ads, no tracking

Telegram’s Privacy Red Flags

• Stores contacts, IPs, and chat metadata
• Phone number required (no anonymity)
• Monetization risks (ads in public channels, premium features)

Champion: Signal (Telegram collects data like most social networks).

Biggest 2025 Update:

• Need secure video calls and group chats

Choose Telegram If You…

• Prefer features over security (1M-member groups, bots, channels)
