Samsung Galaxy Tab is a very popular Android tablet. The first model of the series (Galaxy 7.0) was launched by Samsung in September 2010. Due to the very positive response from customers, several Galaxy Tab models were released including some with larger screens (up to 10.1 inches). The third generation Galaxy Tab 3 is available in three different sizes (7, 8 and 10.1 inches) and features many cutting edge features designed to win the hearts of its customers.
Need a VPN on Samsung Galaxy Tab
The advanced networking and Wi-Fi features that come with the Samsung Galaxy Tab allow you to stay mobile and connected at all times. Be it a mall, coffee shop, hotel or airport; The Galaxy Tab selects wireless signals from hotspot locations and allows you to continue your work without experiencing any kind of interruption. However, the free Wi-Fi available in most commercial establishments is not really secure because the providers use minimum security. This allows hackers and snoopers to steal passwords, banking data, credit card details, and even identity from unsuspecting users.
To protect your privacy and data while using the Galaxy Tab, you should use a secure network solution such as a Virtual Private Network (VPN). VPNs use very high levels of encryption so that your personal and private data remains protected from your ISP, network-based monitoring as well as from unscrupulous elements. VPNs can also help you access services that are not normally available in your country or organization (for example, Netflix, Hulu) by providing an IP address from a different country and even allowing you to bypass restrictions set by your Internet service provider or network.

Setting up a VPN on Samsung Galaxy Tab
To set up a VPN on Samsung Galaxy Tab, there are usually two options available – PPTP VPN and L2TP / IPSec VPN. PPTP is an old VPN protocol that is easy to set up and offers minimal security (maximum 128-bit encryption). On the other hand, L2TP/IPSec is an advanced VPN protocol that offers better security (128+ bit encryption) but is somewhat difficult to configure. There is also a third VPN protocol, known as the OpenVPN protocol, which offers a very high level of security but is not yet compatible with mobile operating systems such as Android. However, it is possible to configure OpenVPN on an Android device, such as the Samsung Galaxy Tab, using applications such as OpenConnect.
In this article, we will explain how to setup PPTP and L2TP/IPSec VPN on Samsung Galaxy Tab.
