A VPN connects a Private Network to a Public Network, allowing users to send and receive data as if they were directly connected to the private network. A VPN provides increased functionality, security, and control of the private network. It offers remote employees access to resources not available on the public web. Although encryption is standard, it is not required for a VPN connection. A VPN is built by establishing a virtual point-to-point connection over existing networks using dedicated circuits or tunneling techniques. A VPN accessible over the public Internet can offer some advantages of a Wide Area Network (WAN). The resources provided within the private network can be accessed remotely by users.

How does a VPN function?
A VPN disguises your IP address by passing it through a VPN host’s specially configured remote server. If you use a VPN to access the internet, the VPN server becomes your data source. This means that your ISP and other third parties cannot know which websites you visit or what data you send and receive online. A VPN functions as a filter, transforming all your data into “gibberish.” Even if someone had your data, it would not be mandatory.
Now, let’s discuss some of the Advantages and Disadvantages of VPN:
ADVANTAGES:
- Protect Your Network
The advantages of utilizing a VPN are numerous. One of the most significant is the ability of enterprises to safeguard their network adequately. Without your knowledge, software or website can track your internet habits. They can then analyze the data they’ve obtained and try to target you with adverts. Without a VPN, you may see an invasion of pop-up advertising, disrupting your surfing experience and being generally annoying.
A VPN can block people, software, and web browsers from accessing your connection. This preserves the security and anonymity of the information you submit and receive.
- Protects your Personal Information
Websites and applications may continuously monitor and analyze your internet activities. A VPN can prevent web browsers and others from viewing your connection, allowing you to send and receive information anonymously and securely. Some VPNs additionally provide military-grade 256-bit data encryption.
- Secure Encryption
To check the information, an encryption key is a must. In the case of a brute force assault, it would take a computer millions of years to decipher the code. With the use of a VPN, your online activities are disguised even on public networks.
- Effectively Prevent Date Throttling
When you have used up a certain amount of data, your internet service provider (ISP) may choose to slow down your connection. If you have a VPN, you’ll immediately find that one of its perks is the ability to bypass a data cap, mainly because your ISP can see how much data you’re using. This might be especially handy for employees who need to use data plans on their smart devices to access the internet while on the road.
DIS-ADVANTAGES:
- Reduced Internet Speeds
The encryption procedure that a VPN uses to safeguard your data takes time, impacting your online experience. The issue is more apparent with specific VPNs than others; thus, it is critical to review the specs before agreeing to use the service.
- Some countries consider it illegal
VPNs are prohibited or strongly controlled in some countries, so always check the local laws.
CONCLUSION:
A VPN does not make your broadband connection “private.” Even if your IP address is concealed, you can still be followed via tracking cookies and device fingerprinting.
A VPN does not protect you from hackers.
