What Is a VPN? Protect the User's Identity and Data

The primary purpose of Virtual Private Network or VPN is to help protect a user's identity and data over public networks including wireless hotspots and the Internet. This is done by creating an encrypted tunnel that is then responsible for transporting data most securely. VPN services are also useful for users to gain access to websites that may only be accessed by users in certain countries.

VPN services use various protocols. The list includes PPTP, IPsec, SSL/TLS and SSTP. Corporate users are more likely to use SSL or IPSec VPN protocols. Since the requirements of an average user are not complicated, the PPTP VPN protocol may be adequate.

The most significant advantage of PPTP protocols is its availability or compatibility with major operating systems. It can also be used on smartphones.

Free versus Paid VPN

These VPN protocols may be obtained for free or for a fee. Free VPN services are not always the best choice. Some risks come with it. For one, there is a possibility of being scammed. Two, the security level offered by free VPN is rather low. Paid VPN services on the other hand, offer much higher security levels.

Three, while support is available to paying VPN clients, a user cannot expect help from a free service. Fourth, users who want to avoid annoying ads should opt for a paid VPN. As with other free services, public VPNs are swarming with advertisements. This is an inconvenience for users who prefer efficient connection.

The essential criterion in selecting a good VPN provider is integrity. If a user's main aim is to protect his identity and personal data from online threats, he must find a provider capable of providing security, safety and protection.
