What is PPTP? Webopedia.
A VPN is a private network of computers that uses the public Internet to connect some nodes. Because the Internet is essentially an open network, the Point-to-Point Tunneling Protocol PPTP is used to ensure that messages transmitted from one VPN node to another are secure.

Which is the Best VPN Protocol? PPTP vs. OpenVPN vs. L2TP/IPsec vs. SSTP. Facebook Icon. Instagram Icon. Twitter Icon. LinkedIn Icon.
The traffic must be converted into L2TP form, and then encryption added on top with IPsec. Its a two-step process. In Summary: L2TP/IPsec is theoretically secure, but there are some concerns. Its easy to set up, but has trouble getting around firewalls and isnt as efficient as OpenVPN. Stick with OpenVPN if possible, but definitely use this over PPTP. Secure Socket Tunneling Protocol was introduced in Windows Vista Service Pack 1. Its a proprietary Microsoft protocol, and is best supported on Windows. It may be more stable on Windows because its integrated into the operating system whereas OpenVPN isnt thats the biggest potential advantage. Some support for it is available on other operating systems, but its nowhere near as widespread. It can be configured to use very secure AES encryption, which is good. For Windows users, its certainly better than PPTP but, as its a proprietary protocol, it isnt subject to the independent audits OpenVPN is subject to. Because it uses SSL v3 like OpenVPN, it has similar abilities to bypass firewalls and should work better for this than L2TP/IPsec or PPTP.
What is the difference between SSL and PPTP and IPSEC VPN? Knowledgebase Server24.
PPTP VPN allows the same secure tunnel but connects using specialized client software on a user's' desktop or dedicated device. PPTP VPN is a great solution for users unable to utilize an SSL connection. IPSEC VPN allows to connect your entire office network to Server24's' private network.
