The technology that provides a secure connection of the logical network over private or public, which is closed from external access, is called VPN. In other words, it is a private virtual network, a network connection that overlays on top of other networks. Connecting a VPN device to a computer or smartphone changes the IP. In addition, the VPN technology uses encryption tools for encrypting authentication of the public key infrastructure to protect data from repetitions and changes in messages transmitted over the logical network. A VPN connection is commonly used for:
- anonymous work on the Internet;
- safe work in a corporate environment from a remote place;
- protection in public networks Wi-Fi cafe stations restaurants and unsecured networks;
- creating a secure channel without hacker attacks;
- circumvention of geographical and legislative restrictions, it is worth noting that these actions are illegal. First of all, it is worth paying attention to those VPN functions that will help protect yourself when using public Wi-Fi and will allow you to bypass the blocking of certain resources. VPN is useful for those who often go online through open Wi-Fi networks from cafe restaurants or the metro. An unencrypted signal is very easy to intercept and access personal data logins passwords card numbers. And if you use a VPN, your data will be encrypted and the attacker will not be able to use it. Of course, if the criminal needs your data and he has sufficient time and equipment qualifications, then your data will be decrypted sooner or later. But this is rather an exceptional case than a mass one. The second feature that VPN users often use is to bypass geographic restrictions, which is often illegal. For example, while in China, we turn to some service, we want to listen to music or watch videos, but we regret to find that this service is not available in our country. In this case, the use of VPN will help access to the Internet will be organized through the VPN server of another country in which the service of interest to us is available. We can say that VPN is a useful and necessary technology that copes well with a certain range of tasks. But the security of your data depends on the integrity of the VPN service provider as well as your common sense of care and discretion.

All things considered, some additional safety measure can't do any harm. "Ensure your Wi-Fi organize is secret word secured, and consistently utilize the most grounded secret word conceivable," he includes. For example, don't utilize evident decisions like "secret phrase," your birthday, or "123456." Also, oppose the compulsion to transfer the screen feed to the Web so you can impart it to every one of your companions and family. baby camera apps by Technical Explore

Thanks to the integration of a VPN with a remote access program, you can get secure access and work on a remote computer from anywhere, whether from a hotel or airport home. All your application files and mail are just a click away from you wherever you go.

VPN technology is used to provide secure access to the corporate network and its resources through the public Internet. This is especially true when using a public Wi-Fi hotspot or other unsafe connection methods to connect to the Internet.

The information exchanged between the two VPN endpoints is encrypted and therefore no interference can occur when the information is transmitted over the public network. Depending on the protocols used and the destination, the VPN can provide connections in different ways.

Finding free VPNs is easy, it’s harder to choose reliable services from them without hidden fees and charges.
Most free VPN classic cheese mice. Limited traffic volume, trimmed speed and no choice of server locations.
Sometimes it’s still more serious and a free VPN directly threatens your privacy on the Web. Therefore, we always advise you to work with full versions of services.

Protected virtual network is able to provide reliable transmission of encrypted data over the Internet. Examples include PPTP, OpenVPN, and IPSec. If the transmitting environment is considered sufficiently reliable and security issues are resolved within the basic local infrastructure, you can configure and use trusted TopVPN connections (usually used in tandem with IPSec) or MPLS.

Triple DES is the most commonly used encoding algorithm. It provides 168-bit encryption with three different keys. This gives a one-hundred-percent guarantee that only the user who has the appropriate rights can read the data. There are no effective algorithms for cryptographic attacks on this symmetric cipher, which means that the probability of its decryption even by a professional hacker tends to zero.

VPN is mainly used in two cases:
1. Ordinary users, in order to bypass site blocking or to hide the real IP address assigned by the provider. For this, either a browser with built-in VPN technology or a specialized service is used.
Suitable for this TopVPN
2. Organizations - to build a virtual local area network to provide encryption of the transmitted data between computers on the network and to avoid data leakage. The provision of such services is carried out by more serious companies than for ordinary users.
