The PPP is a “regular” data link layer communication protocol that connects two routers without hosts. Initially, PPTP was designed as an improvement over PPP (Point-to-Point Protocol). The protocol was developed by a vendor consortium comprised of Microsoft, Ascend Communications, 3Com, and others. The PPTP protocol came into public use in 1999, while the beta version was available as early as 1997. If your questions are “What is PPTP exactly?” “What made it great?” and “How did we abandon it?” here’s a rundown of the veteran protocol’s history and use cases. Nonetheless, PPTP is still offered by practically every VPN provider. On the other hand, the PPTP VPN protocol comes with some glaring security vulnerabilities, making it less than ideal in a world of already fleeting privacy and anonymity. The now-22-year-old protocol is still among the fastest, plus it’s incredibly easy to set up even for the least tech-savvy of users. While rarely used nowadays, PPTP still has a bunch of perks some other protocols lack. It’s so old that it was originally designed to tunnel dial-up connections just like dial-up connections, PPTP is now considered obsolete, and has been replaced by modern, more advanced protocols like OpenVPN and WireGuard. PPTP (Point-to-Point Tunneling Protocol) is the oldest VPN protocol for general use.
