Virtual Private Network (VPN) allows users to securely access remote networks and resources as if they were locally connected. It works by encrypting data in transit and tunneling internet connections to maintain integrity and confidentiality. VPNs offer benefits like remote access to files/devices, connecting branch offices globally, and accessing restricted websites by changing the IP address. There are different types of VPN connections that use various encryption protocols at different layers. VPN services are an easy and flexible way for businesses and individuals to securely access networks from anywhere at any time on any device.

1. Virtual Private Network(VPN) Feature
and Benefits

2. Virtual Private Network(VPN)
 A virtual security appliance is a computer appliance that runs inside virtual
environments. It is called an appliance because it is pre-packaged with a hardened
operating system and a security application and runs on a virtualized hardware.
 Virtual security appliances are playing a significant role in meeting your expectation
today and will continue doing the same in the future.

3. How Does VPN Function
 As soon as you connect to the VPN, the VPN client interface is launched on your
computer. This in turn will require you to fill in your credentials with a remote
server.
 This helps both the systems in verifying each other. What’s more, as the Internet
communication is encrypted, it ensures that the integrity of data is maintained
throughout its path.

4. Why YourBusiness Needs A VPN
 A VPN service changes the IP address assigned to the computer. This enables you
in accessing sites which may be banned in your country. This can prove to be of
great help if your business requires specific data. For example, you are a player
operating in the media industry and are working on a certain story. It is quite
possible that during the course of your research, you may need some information
which has been censored by the state. This problem will be taken care of if you are
using a VPN.
 Using a VPN helps you to provide the much needed access to your employees to
remote devices such as files, printers, applications, etc. via the Internet. You also
do not need to take any extra measures in order to secure the network.
 Using a VPN will also help you in connecting multiple networks, hence, making it
possible for you to connect your branch offices located across the globe (if this is
the case).

5. Types Of VPN
 IP security protocol or IPsec is one of the types of VPN connections that is
available. IPsec uses Layer 3 of the OSI model to encrypt the data.
 The second type of VPN connection available is Layer-2 Tunnel Protocol or L2TP.
A point to point tunnel protocol along with Cisco Layer-2 is used for this. Secure
Socket Layer or SSL is the third type of VPN connection that is used. SSL depends
on certificates to verify the identity of a server or a computer.

6. Who Does VPN Work?
 Most people don’t have a clear idea about how VPN works. A general perception is
that when you connect through a VPN, your data is secured and cannot be
accessed by anyone else. However, if you look into the technical side of it, VPN
uses the technique of tunneling. When data is sent through internet, it is divided
into packets. The data is further divided into ‘bite sized’ pieces to send with ease
and convenience. VPN uses tunneling protocol and encryption to secure your data.
 In order to prevent your data from being accessed by someone else, the data will
be encrypted. Encryption is a process where the encoded data can be decrypted
only by an authorized computer. Anyone who tries to intercept the data on public
network will not be able to read it. Public-key and symmetric-key are the two main
types of encryptions that are used.

 Assured VPN connectivity, hence higher security levels
 Anywhere, Any Time, Any Device VPN connectivity
 Flexible options
 Eliminates the need to install VPN clients over individual devices

8. Selecting the Right VPN Service
 Businesses with offices and presence across the world feel the need of connecting
with their employees at different locations through a fast, secure and reliable way.
This is where a Virtual Private Network (VPN) comes into picture. It is a group of
computers or discrete networks connected to each other over a private network
which is the Internet. While businesses can connect remote datacenters through
VPN, individuals can use it to access network resources without being physically
present on the same LAN.

9. Advantages Associated With Using A VPN
Service
 The data that you send and receive is encrypted. Hence, Using a VPN network
ensures that your communications are not picked up by any unauthorized party.
This also helps in maintaining the integrity and confidentiality of the data.
 You do not need to be an expert in order to set up and use a VPN system. These
systems are user friendly and easy to understand.
 Service providers have come up with various flexible plans like a monthly or an
annual subscription plan. You can choose from among these options the plan best
suited to meet your business needs. This has also helped the providers to cater to
the varied needs of their VPN clients.

10. Disadvantages of VPN
 VPNs require an in-depth understanding of public network security issues and
proper deployment of precautions.
 The availability and performance of an organization's wide-area VPN (over the
Internet in particular) depends on factors largely outside of their control.
 VPN technologies from different vendors may not work well together due to
immature standards.
 VPNs need to accomodate protocols other than IP and existing ("legacy") internal
network technology.
