http://cyberblogue.com/tag/convert/ VPN protocol plays an important role in providing speeds, security and privacy. VPNs and VPN protocols are different. VPNShazam is a VPN service that lets you choose from a variety of VPN protocols depending on your needs. VPNs transmit our online data through tunnels that are highly encrypted to VPN servers. VPN protocols are a set of programs that determine the tunnel’s formation. All protocols provide a different solution to security and privacy. Let’s review some main VPN protocols so that you can choose the one which suits you the best.

OpenVPN

OpenVPN is a highly secure VPN protocol that is used by many VPN providers and individuals as well.

Pros:

Open VPN has an open source code which leads to a variety of benefits, out of which transparency is its most important asset. OpenVPN can be configured for different purposes as per the need of the user including different encryption and traffic protocols. OpenVPN is very secure.

Cons:

It has a complex setup i.e. people with less technical knowledge cannot set up their own OpenVPN. Luckily, VPNShazam can set up OpenVPN and  also can manage it for you.

L2TP/IPSec

L2TP only creates a connection between the user and other servers of his VPN, it doesn’t provide any encryption. Although L2TP has few convenient features, few issues prevent it from being the recommended protocol.

Pros:

L2TP does not offer any security hence it actually could be highly secure as it can accept a wide variety of encryption protocols making it lightweight. All modern consumer systems have L2TP and getting it running is no at all a trouble.

Cons:

L2TP is potentially compromised by NSA. It usually uses IPSec and NSA could probably break 66% of IPSec VPNs. L2TP is much slower as compared to other protocols as encapsulation in L2TP is done twice. L2TP cannot easily clear through firewalls but with VPNshazam configured there are ways to get through these firewalls.

IPSec/IKEv2

IKEv2 is a security protocol that establishes an authenticated and encrypted VPN connection between two systems. Developed by Cisco and Microsoft it is fast and secure. Its important asset is it stability. IKEv2 uses IPSec tools to provide a wide VPN coverage.

Pros:

IKEv2 is the most dependable as well as stable protocol fro mobile devices. Mobile users often move from one connection to another and IKEv2 with IPSec tools ensures that VPN stays connected. It is one of the most secure VPNs with most leading algorithms for encryption. It is very efficient as it takes only a little bandwidth in its active state.

Cons:

IKEv2 isn’t compatible with many systems. But with VPNShazam it works on systems with proper version upgrades. Just like L2TP, IKEv2 as it uses IPSec tools is compromised by NSA as well. During leaks slides in NSA presentation showed that they might have a way to break the key exchange procedure. Although patches for these have been updated, vulnerabilities could still exist.
