With the shocking revelations by Edward Snowden of NSA’s frantic efforts over the years to crack into and to subvert the VPN encryption technologies, and with the latest news from China of complete interference with VPN, it is important to revisit the VPN discussion in the hope that you will interrogate just how well you are placed with securing your networks and your pertinent information. Another point to consider is the fact that most VPN technologies are certified and developed by the by the National Institute of Standards and Technology.
Let us now take a look at the available protocols and what they offer
PPTP
PPTP (Point-to-Point Tunneling Protocol) has been for a long time the standard protocol used for internal businesses as VPN. This is because it was created for functioning as VPN over dialups by a consortium that was founded by Microsoft. It is easy to set-up as it is compatible with almost every platform and device capable of VPN, and it does not need any additional software for one to install.
VPN over PPTP is popular with businesses, people as well as VPN providers because of ease of use and the fact that it is quick as it needs low computational power. Although it is currently found only through 128-bit encryption, there are a number of vulnerabilities that have been found with it to the extent that Microsoft have recommended those using VPN should consider using L2TP/IP sec.
The knowledge that PPTP was not secure only serves to confirm the fears that NSA would almost certainly decrypt current and even historical information encrypted under this protocol.
This can still protect your identity online and change your IP especially if the proper security measures are set and active on the VPN server.
L2TP
Layer 2 Tunnel Protocol offers the highest level of encryption. It also checks the integrity of data before it encapsulates the data twice.
When properly implemented with the complementary use of IP Sec or the use of port forwarding as in the case of use behind a firewall, this protocol has the potential of being on the best protocol. It is however slightly slower than PPTP and it is available on almost all modern platforms. The speed is affected by the server and personal computers power, but the difference is not even noticeable by the eye making L2TP a great option to consider.
There are still concerns that this protocol would likely be compromised or weakened by NSA, but with proper and what we consider standard safety practices, as other protocols, this becomes a great protocol to use and be certain that your information is safe.
OpenVPN
Open VPN also has one of the highest encryption algorithms as it authenticates the data by way of digital certificates. This protocol is the most reliable, most compatible and most stable for all manner of environments. It is also fast, recording the highest performance levels of the three protocols.
All 3 are great for their own reasons and now you have more details about which one might be better for you depending what you use your RapidVPN account for.
