Telegram, Signal, Threema, WhatsApp in comparison: privacy, GDPR, encryption data storage – WhatsApp and Facebook Messenger – are particularly divisive. The two messaging apps from Facebook Inc. When it comes to security, however, there are major prejudices and rigid views instead of facts. Whether Signal App, Facebook Messenger, Telegram, Threema or WhatsApp – messaging apps are used more than any other app. Messaging apps are by far the most popular communication medium of our time. In addition to my experience as CMO, MessengerPeople, this analysis also includes the comments of various experts, researchers, hackers and lawyers who have assessed the topic from the perspective of their respective areas of expertise. That this is far from being the case is what I would like to show in this article. In contrast, Telegram, Signal or Threema are generally considered to be secure. I don’t believe any form of communication short of telepathy is 100% secure.Is WhatsApp secure? Does WhatsApp read my messages? What is end-to-end encryption? Will my data be sold? Which messaging app is really secure? Where is the difference to Telegram? These are questions that I am asked again and again. No encryption should be assumed 100% unbreakable either since the trend historically has shown attacks being discovered long after usage is adopted, eg SSL.įinally finally, please share this around! It’s probably better safe than sorry for all those out there who believe their communications to be 100% secure. Intelligence agencies have interests in developing encryption for national security reasons, so often they fund research and/or employ people connected with such research. NSA has participated in development of AES, DES, SHA and other commonly used encryption. Involvement of intelligence agencies in a crypto company or technology is not evidence that the technology or company is insecure. If you choose to use either of these apps, you are probably much safer than if you merely use unencrypted texting or email. Nor are the concerns about Pavel joining the World Economic Forum. That all said, the evidence above is not conclusive that Signal is a “honeypot” that sells your data or metadata to the US government. It is this author’s opinion that the point is moot, given that users can choose to utilize Telegram’s peer-to-peer mode if they desire.įinally, before we flesh out a few details, a fact that may concern many of us, especially when we care about our personal conversations being shared with governments: This is at the core of complaints that Telegram is “not as secure”. And for Telegram to share your data, if they chose to. Your messages are still encrypted.īut yes, the server in the middle does introduce an added potential for hackers to intercept your messages. The most useful of these extra features provided only by Telegram, being able to start a conversation on your computer, jump in your car, and continue the conversation on your phone, requires a server in the middle. Why does Telegram even provide, peer-to-server-to-peer as an option? If you have played with both apps or looked at the comparison chart above, you may have noticed how many more features Telegram has. Maybe they just like the fact that Signal makes the decision for you and Telegram gives you too many pesky choices? Some sources either do not know this feature exists (always has) or they choose to ignore or misrepresent this fact. Signal’s default (and only) mode is encrypted peer-to-peer, while Telegram’s default is encrypted peer-to-server-to-peer, with an option for encrypted peer-to-peer, which Telegram calls “Secret Chat”. So, given the facts above, why are most mainstream sources reporting that Telegram (a) doesn’t have peer-to-eer (end-to-end) encryption and/or (b) Telegram’s encryption isn’t as “good”? The short answer:
