There are numerous VPN types providing different levels of online protection.. VPN types are differentiated by the tunneling protocols used, such as PPTP, L2TP, IPSec and SSL. Let’s first address what VPN is.
VPN (Virtual Private Network) is a private network that is established over an existing public infrastructure by creating a tunnel secured by various tunneling protocols. Upon subscribing to a VPN subscription, the user’s system is connected to a remote VPN server based in another country. The tunnel is secure because all information is encrypted before it is routed through the tunnel. Moreover, accessing the tunnel requires authentication. It is secured by using various VPN protocols like IPSec, L2TP, etc. Using encrypted tunnel is what sets VPN apart from all other online protection tools.
Furthermore, a new IP address is generated from a distant server and the real IP address is masked. It enables users to surf anonymously because no one can identify the generated IP address. Users living in Internet-censoring countries like China, Saudi Arabia, Kuwait and Syria would also be able to bypass restrictions imposed by local firewalls. VPN can also allow users to access Geo-restricted streaming sites like Hulu and Netflix.
Various Types of VPN in Nutshell
Now, we would discuss various VPN types with their characteristics so that it would be easier for you to decide which type of VPN meets your requirements completely.
This is an acronym for Layer 2 Tunneling Protocol. It offers no encryption by itself but instead uses the encryption of protocol. Being an OSI Session Layer protocol, it is used as a layer 2 Tunnel. It makes use of Cisco’s Layer 2 Forwarding (L2F) and also uses various features of Point-to-Point Tunneling Protocol (PPTP) VPN.
IPSec has become one of the most used VPN types. Functioning on a Layer 3 of OSI Model, it offers fabulous end-to-end security. Though it offers impenetrable security, third-party hardware or software must be used. Installation of an IPSec client software application also is required. It is imperative for you to configure the application before using IPSec VPN.
SSTP (Secure Socket Tunneling Protocol) VPN offers a high level of online security. It has improved and fixed the flaws present in Point-to-Point Tunneling Protocol (PPTP) or Layer 2 Tunneling Protocol (L2TP). Using SSTP, one can easily beat firewalls and web proxies as there will is no port blocking. It offers better security because of using stronger tunneling protocol. It is the preferred choice for users looking to unblock sites in Internet-censoring countries.
This is the most commonly used VPN and is used in all windows and smart Phones. Having got fine authentication features which can PPP-based protocols like PAP, EAP and CAP, it is the reason for being so popular amongst users. Though it is known to have certain problems with security yet it is widely used. However, it is recommended that you should prefer PPTP for streaming services rather than sensitive data transfers.
