![]() This also depends on the company’s local jurisdiction. Historically, it is common for VPN providers to keep basic connection logs (user’s IP address and VPN connection timestamps) for a period ranging from 2 days to 6 months or more. Genuine VPN providers should never keep traffic logs, however it is possible that when their service is misused, certain technologies may and do occasionally get used to identify the most malicious users. Most VPN providers officially claim that they do not keep traffic logs, however it’s always important to check the company’s privacy policy and location of their headquarters (in terms of jurisdiction). On the other hand, proprietary protocols are often supported well by their corporations, but because of their confidential nature they may be vulnerable to unforeseen security flaws.įor a more in-depth comparison, have a read of our guide to VPN protocols. This public review process has proven to create a more secure product. Open protocols are subject to peer review by the greater public. SSTP is also very secure and is difficult to block, though usually it is fairly slow. What’s more, OpenVPN uses multiple ports and is capable of avoiding port blocking, though it may be slow due to opposing factors. OpenVPN is regarded as the most secure and is the most widely implemented protocol it is often modified/enhanced by providers and can be very fast depending on encryption level and server response. Technically, L2TP/IPSec is secure, though it was allegedly compromised by the NSA and is often blocked by robust firewalls. PPTP is known for being fast, though it is very insecure and easy to block. PPTP and SSTP are proprietary protocols, while L2TP/IPsec and OpenVPN are open source protocols. ![]() Bear in mind that not all VPN providers support all of these protocols, SSTP and IKEv2 being the notable exceptions, but most will support the other three. ![]() Currently, there are several protocols in use today, including the most popular OpenVPN, along with PPTP, L2TP/IPsec, SSTP and IKEv2. The main facets to consider are reliability, security, performance, and ease of use. Choosing a protocol depends on what you would like from your VPN.
