Everything is founded by the Signal Technology Foundation (Signal Foundation), a fully independent non-profit organization, and, might we add, with no links to major tech companies. The platform was founded in 2013 by Matthew Rosenfeld, founder of Open Whisper Systems. Signal is a secure and open-source messaging with a strong inclination towards privacy protection enforced by one of, if not the best encryption algorithms out there called Signal Protocol. Nowadays, there are a couple of good options when it comes to highly secure messaging apps, but probably none more popular than Signal. The thing is, all those advantages come at a great cost usually in the form of our privacy and personal data. Be that as it may, they're still not widely used, since we all know what advantages other, more mainstream platforms bring to the table.
Privacy-focused and secure messaging applications are not a novelty.
