VPN is a connection between one network and another network privately through a “public” Internet network. It is called a Virtual Network because a VPN uses the Internet network as an intermediary medium, aka the connection is not direct. So that when you use a VPN, the security of your data will be guaranteed and one of the most trusted VPNs is best vpn and proxy.
And it is called a Private Network because VPN is private, meaning that only certain people can access it. The data sent through a VPN is encrypted so that it is quite safe and the secret is still maintained, even though it is sent over the internet, that is the definition of a VPN.
Pros and Cons of a VPN
1. Advantages of VPN
– Remote Access, with a VPN we can access a computer or office network, from anywhere as long as it is connected to the internet
– Security, with a VPN connection we can surf safely when using public internet access such as hotspots or internet cafes.
– Save on network setup costs, VPN can be used as an alternative technology for connecting large local networks at a relatively small cost, because VPN technology data transmission uses existing public network media without the need to build a private network.
– There is no dependence on having to have a Public IP which is expensive. It is enough to just use a dynamic IP in other words as long as your PC can surf the internet.
– You can transfer data or remote view to control your home/office computer anywhere
– Does not require additional equipment/hardware that functions as an IP forwarder / Port Forwarder which adds to your investment.
– Wherever you are like you are in an internet cafe or when you are traveling abroad, you can connect with a PC at your office, for example by utilizing software that works on LAN networks such as Citrix, Windows Terminal Server 2003, VNC, Radmin, VOIP, etc.
– By using software that works on the LAN network you can exchange data directly, Printing, Remote Viewing, Managing your PC administration, all of which can be done wherever you are as long as you can connect to the internet
– Can access blocked access
– Surf safely when on public internet access/hotspots
– If the company wants to optimize costs to build its extensive network. Therefore, VPN can be used as an alternative technology to connect large local networks at a relatively small cost, because VPN technology data transmission uses existing public network media.
2. Disadvantages of VPN
– Internet connection (public network) that we cannot predict. We can understand this because we are just “join” a connection to the other party’s network so that automatically we have no control over the network.
– More attention to safety. Again, due to the use of public networks, we need to pay more attention to prevent unwanted things such as wiretapping, hacking, and cybercrime on VPN networks.
– prone to wiretapping
– No Main User Controls
– Device Mismatch
– Absence of Compliant Standards
