A VPN or Virtual Private Network is a tool that grants a safe and secure access to the internet. It starts with encrypting your data before connecting to the web. The data then proceeds to a VPN server, changes your IP address and location (if desired). This updated information is then fed to the online destination. The person who receives this data will not be able to see the source of the data. It is a great tool to protect privacy and stay secure while browsing online. 
Let us consider a few cases where VPN can be used to make life easier:
1. Online Banking
In the current times, when online transactions are a major mode of payment across businesses globally, it is crucial that we take utmost care while making these transactions. It could be your money, employees’ salaries or business payments! Using a VPN will keep the data encrypted during these transactions, thus keeping it safe from hackers. In these times, it is important that we always use VPNs for online banking or other transactions.
2. Defense/Military
VPNs used for military communication purposes need to meet much higher requirements than general VPNs. To adhere to the robustness of the requirements, certain certifications are necessary for military grade VPNs. Both hardware and software VPNs are a good fit for secure military communications. Communication network is also an essential factor to consider while choosing an appropriate VPN for military communication.
3. Hospitality/Traveling
It is not a surprise that while traveling and staying in hotels, we tend to come across hotel WiFi or other public WiFi that might not be secure, hence retrieving sensitive data. Using a VPN encrypts the data between the device and the internet, making the internet usage much safer. While it is tempting to use FREE and high speed WiFi, it is a wiser decision to use it with a VPN for safety and security.
4. Online Shopping
Using a VPN while online shopping is a great idea to avoid country specific sites while traveling abroad. It is also useful while booking flight tickets since the IP address is encrypted and the website cannot get your details to hike the price depending on your searches. 
5. Geo Blocking
Sometimes internet content might be blocked due to a user’s location. One might travel abroad and find out that TV show/movie website is blocked outside of the home country. In such cases VPN servers can solve this issue and allow the streaming of your favourite shows without any issues.
VPNs are great	 for privacy protection and enhanced internet security. A VPN provides an encrypted tunnel for data transmission between the user and the company network. This data can not be read by any third party since it is encrypted and well secured. VPNs protect users from various cyber attacks such as identity theft, or data theft. A VPN hides your IP address, location, browsing history, your web activity and devices, hence enhancing your data security.
There are various encryption protocols for VPN implementation. Let us discuss a few:
SSL/VPN:
It is a secure socket layer VPN that enables users to gain access to an organization’s network, applications and directories without using any software. SSL VPNs are crucial to provide connectivity to employees for the work applications they require and for IT so that only authorized users receive access. SSL VPNs provide safe and secure communication through encrypted connection for every type of device regardless of the type of network.
IPSEC/VPN:
