In a world where privacy is under increasing pressure, more and more people are looking for alternatives to WhatsApp. Signal is often cited as the safe choice. But how secure is Signal really? And isn’t centralization a risk in the long run?
Signal’s promise: privacy and encryption
Signal is known for its end-to-end encryption and minimal metadata storage. It is a nonprofit that takes privacy seriously and does not use ads or tracking. This makes it an excellent choice for people who want to keep their conversations private.
But there is one major drawback: Signal is centralized. All messages go through the Signal Foundation’s servers. This means that if these servers go down, get blocked or are pressured by governments, the entire service is vulnerable.
Centralization: a risk in the long run
Signal’s success is both a strength and a weakness. As the app grows exponentially, problems may arise:
- Outages: When Signal’s servers go offline, no one can send messages. This has happened before during major outages.
- Censorship: Governments in countries such as Iran and China have already blocked Signal, showing how vulnerable a centralized system is.
- Government pressure: Signal may face legal requirements to build in backdoors or collect metadata.
Moreover, Signal still uses Big Tech services such as Amazon Web Services (AWS) and Google Firebase for push notifications. This begs the question: how independent is Signal really?
Are there better alternatives?
For those who really want control over their data, there are decentralized alternatives such as:
– Element (Matrix protocol): A completely open-source and decentralized platform. Users can host their own server or choose a public one.
– Session: Uses a network of decentralized nodes and does not require a phone number.
– Briar: Works without central servers and even without the Internet via Bluetooth or mesh networks.
These alternatives eliminate the risks of centralization and better fit the Web4 vision of an Internet where the user is in control.
Conclusion: Signal is good, but not perfect
Signal is a big step up from WhatsApp, but it is still a centrally managed system with some risks. If you’re looking for true independence and privacy, decentralized networks like Element or Session are a better alternative.
At HostService, we believe in an Internet where users are in charge of their own data. That’s why we offer certified nodes and solutions that contribute to a truly decentralized Internet. Because privacy shouldn’t depend on one organization – it should be in the foundation of the Internet itself.
