What is a VPN and How business users see it

Virtual private networks (VPNs) are security measures for private networks that use the internet to communicate with each other.

Businesses often implement them to allow remote workers to connect securely with company servers, allowing employees to access the company’s system from a remote location.

VPNs protect data by providing a secure tunnel through which to transmit it, and they provide authentication so only approved users can enter the tunnel.

The benefits of using a VPN include enhancing security, ensuring that only authorized users have access to protected information, allowing employees to work from their homes or other locations, and preventing unauthorized users from accessing business data.

How does a VPN Work?

VPN technology helps you to securely connect to remote servers and encrypt your data.

A VPN works by creating a virtual encrypted connection between two points over the internet: one point on the Internet, where you’re sitting; and another point on the Internet somewhere else (the destination).

A VPN encrypts your computer data using 128-bit or 256-bit key encryption technology which is unbreakable.

This VPN software also protects your IP address to prevent hackers from stealing your data while you’re connected to the Internet.

You can secure your traffic and hide your location so you cannot be spied on by others.

So as far as anyone snooping around is concerned it looks like those bits of data are traveling to and fro in mid-air.

No one can decrypt them until they reach their destination, because only you have the encryption code for your secure connection.

Who uses a VPN?

A number of different types of users benefit from using a VPN.

Remote workers: Most businesses have some employees who work from remote locations, including telecommuters and traveling businesspeople.

A VPN allows them access to the company servers so they can communicate with co-workers and perform company tasks from a remote location.

Mobile users: Another type of user that benefits from using a VPN are mobile users, including many types of freelancers and business people.

Because mobile devices such as smartphones and tablets can use data services without the user having to get a separate phone service for them, adding a VPN service to that plan allows these users access to company resources from anywhere they get an internet connection.

Users in countries where the internet is censored: In some countries, the internet is censored, or access to certain types of websites is not allowed. 

In those cases, a VPN allows users to “tunnel” into the country through another location – for example by making it look as if the user’s computer is in a country where access to the site isn’t banned – and get around any restrictions.

Businesses often use VPNs to allow employees to access company resources remotely.

Businesses benefit from VPNs in the following ways:

Enhanced security:

A VPN enhances security by providing a secure tunnel that makes it impossible for unauthorized users to access data or information.

Only authorized users: Using authentication and authorization protocols only authorized users can enter the VPN. This ensures that no one who does not need access to specific information can gain access to it.

Enhanced privacy: A VPN is also used to enhance privacy. It ensures that personal and business data is safe and secure on shared networks.

Increased flexibility: A VPN also allows employees the flexibility to work from home or other remote locations, which increases productivity and reduces operational costs for employers.

Remote control:

Remote workers often use VPNs to connect with the company network and allow for remote control of other computers.

This can simplify tasks that might otherwise need attention from co-workers, such as printers needing new print cartridges or broken document scanners needing repair.

Share files:

Some VPNs include the ability to share files across networks. This functionality would be useful, for example, if two employees both needed access to a file stored on a server. They could each use their own laptop with an installed VPN client to gain access to their company’s network and the shared file.

Online anonymity

Many VPNs include features designed to allow users to remain anonymous. This is especially important for online gamers, as they can be recognized by their network address and sometimes tracked as a result.

Unblock websites & bypass filters

Some VPNs also allow users to access sites that are blocked in their area. For example, some companies block personal social networking sites on business networks, but employees who use a VPN could bypass the filter and gain access to those sites.

Change the IP address

Many businesses use a static IP address for their business internet connection. A static IP would be problematic, however, if multiple employees wanted to access an online resource or service through a VPN at the same time. In this case, a dynamic IP address that changes every few days would help ensure that no one else is using it.

Better performance:

VPNs can also improve performance by handling the encryption and decryption of data, which online security protocols require. This means that employees can access resources faster and with fewer interruptions.

 

Reduce costs:

Finally, a VPN can help reduce costs. Since employees can access resources remotely and often don’t need to be added to the company’s network, businesses only have to pay for a single internet connection rather than several.

Conclusion:

A VPN is a private network connection that allows authorized users to access resources remotely, which enhances security and privacy and offers other benefits such as increased flexibility and reduced costs.

A VPN can be used by businesses to allow employees to access company resources remotely across shared networks and the internet, for example by employees who want to work from home or need remote access to company resources.
