VPN (Virtual Private Network) in English means “virtual personal network”. In the fullest sense of the word, it is a closed, that is, not open, secure network.
Where are VPNs used?
VPNs are commonly used in practice to encrypt and secure a network between one enterprise and another enterprise, between branch offices, or between a user and a known server.
A VPN actually creates a secure network and encrypts information that is exchanged internally. As already noted, it is mainly used in corporate networks to protect information.
Is it safe to use a VPN?
If it is used for information security purposes on a corporate network and the settings are made by you personally (known to you, understandable), then it is safe.
Unknown or free VPNs are not considered reliable. This is due to the fact that all your information may be disclosed to third parties. For example, when you use a VPN on a mobile phone, at least the following information comes into the hands of the person who created the VPN:
- All websites you visit;
- Information that interests you;
- Payment, card information;
- Your IP address.
In addition, it was recently reported in Internet news that hackers shared personal information, photos, etc. of free VPN users on various Internet sites. You can read more about this on the Internet.
Therefore, it is recommended to maintain information security and use software and technology on the ground of scientific attitude.
