Are you feeling confused about choosing the best vpn for pc package for you to use? In this article, we will compare several VPN protocols for you to consider:

OpenVPN (which is an abbreviation of the open-source virtual private network) is the most famous VPN protocol. Its popularity is based on the factor of a strong and high-level encryption system and its open-source code. OpenVPN is supported by all major operating systems, such as Windows, macOS, and Linux. This protocol is also supported by mobile operating systems such as Android and iOS. Of course, one of the main objectives of the VPN protocol is to provide a high-level data encryption system. In this area, OpenVPN works very well. Basically, OpenVPN uses 256-bit encryption through OpenSSL. All this was according to:

The use of TCP ports means that each individual “data packet” must be approved by the receiving party before the new packet will be sent. This makes connections very reliable and secure, but slower.
It is faster than OpenVPN-TCP. All “data packets” are sent without the consent of the recipient. This results in a faster VPN connection, but a reduced level of reliability and stability.

The advantages and disadvantages of OpenVPN
+ OpenVPN is very safe
+ Supported by many software and virtually all modern VPN providers
+ Supported by all operating systems basically
+ Be audited and tested extensively
– Sometimes requires additional software

Point-to-Point Tunneling Protocol is one of the oldest. The NSA has succeeded in exploiting the security flaws of the PPTP protocol. This, and because of the lack of a high-level encryption system, is the reason why this protocol is no longer considered secure. However, the lack of a strong encryption system from PPTP means this protocol has a very fast connection. Because PPTP is very old, the VPN protocol is supported by several different devices and systems. However, firewalls that try to block VPN users, in general, will be fairly easy to recognize PPTP users. This certainly does not make PPTP the best protocol available for the purpose of unblocking (and as for other good security features).

The advantages and disadvantages of PPTP
+ Very fast
+ Simple and easy to use
+ It fits virtually all operating systems
– Only offers basic and low-level encryption
– Easy to recognize and block by firewalls and other parties
– Hackers often exploit weaknesses from PPTP security

IKEV VPN protocol2
Stands for IKEv2 is Internet Key Exchange Version 2. As the name suggests, your data traffic will first be encrypted by the IPSec protocol. Then, a secure VPN tunnel will be created as a place for all your (encrypted) data to pass. This means that some firewalls will block IKEv2 users. The use of IPSec as its encryption system makes IKEv2 considered by many to be as safe as the L2TP / IPSec protocol. But there is a note that must be considered here: when using a weak password, IKEv2 is very vulnerable to hackers.

Advantages and disadvantages of IKEv2
+ IKEv2 is very fast
+ encryption is quite a high level
+ able to recover lost connections
+ simple and easy to use
– can be easily blocked by multiple firewalls
– possibility of being exploited by the NSA
– not safe when using a weak password
