PPTP is a VPN protocol released by Microsoft in 1995. For many years, PPTP was the industry standard, and most modern systems still support it. It’s quick and easy to set up and comes pre-installed on most operating systems. PPTP sets up a tunnel between two points through TCP port 1723. It then encrypts all your data with 128-bit encryption and encapsulates it in an IP envelope. Today, it has many known security vulnerabilities. Buy CyberGhost VPN to defend your digital castle.
