Currently VPN services are in significant demand among people who prefer to keep their privacy and online activities secret. VPN services are essential for preventing malicious hackers from credit card payment data. There are numerous commonly known cases when criminals eavesdrop personal data while their unsuspicious victims are connected to a Wi-Fi network either public or home.
Technically VPN is a remote server that routes and encodes all sent and received information. After you pass the VPN server identification and authorization process successfully, its algorithms conceal your identity, online activities and geographic location by encrypting your traffic.
Originally VPNs are corporate networks that ensure a safe encrypted connection between employees’ computers and company's server. These kind of networks give colleagues from different departments and subsidiary branches the possibility to collaborate remotely. VPNs assist office maintenance expense reductions by letting employees work from home or even from other countries.
The application of VPN technologies for individuals commenced by the Chinese who were trying to get around “great firewall” restrictions. Now people even from the most democratic countries evaluate the advantages of protected surfing on the Internet.
VPN operating principle:
- A client connects to a VPN server from his computer then passes identification and authorization.
- The information between remote computers could be swapped securely if computers are interconnected through the VPN server. Transmitted files pass the VPN server before reaching any computer from the network;
- VPN technology routes the traffic over the public channels using the sophisticated encryption.
VPN network security
VPN network security is achieved and maintained through the usage of some extremely important features of the service. Without these basic characteristics an app can’t be called a good VPN. A customer-oriented VPN service provider should make everything possible to equip its clients with topnotch solutions. VPN security depends on the following fundamental features:
- A wide server park
As you know, many filtering systems used by administrations of some geo-restricted websites and resources, as well as companies doing with targeted ads trace back actions to users through their authentic IP addresses. That means that your online confidentiality depends on your address. A good VPN service provides a wide server park with many servers located in different countries worldwide. Having connected to the Internet through one of the servers, your true address is substituted with a server’s one. Therefore, you have a possibility to hide your identity and geo-location to bypass geo-restrictions and avoid eavesdropping.;
- Encryption methods
All the existing encryption methods are focused on making your generated traffic unreadable and unattainable for any unauthorized access. There are many protocols that differ in functions. Some of them are oriented to traffic encryption only, while others fulfill some additional parts like routing the ciphered traffic through a secure tunneling.
- Unlimited bandwidth and speed
Fastest VPN providers make their service limitless in bandwidth and speed. This characteristic gives customers a possibility to watch any streaming content in a high quality, as well as enjoy multiplayer games without any lags and hits.
- NO logging data storage
If you want to get a private VPN, you should pay attention to its provider, whether it stores any data on its customers or not. A highly-anonymous service saves no logging or metadata on its clients, which makes it extremely reliable in terms of confidentiality. In this case no of your personal information can be handed over to some interested third party.
- A free trial version & a money-back guarantee
A well-trusted paid VPN suggests its clients testing its service for free, which gives a chance to see whether the service suits you before subscribing for it. Besides, such services provide a money-back guarantee that allows any customer to get his money back, in case he is dissatisfied with the service.
- VPN add-ons
As soon as there are many VPN outputs on the market today, different companies try to catch customer’s interest through supplying their products with some new stuff. Due to this fact, we can see such add-ons as kill switch, warrant canary, DNS leak protection, sorting servers by speed and etc.
If all the demands are met by a provider, the service will make your network secure and protected from multiple online threats. In any case, choosing a VPN service is a sensitive task that requires basic understanding of the question. Therefore, being a newbie of the sphere you need to learn some data on VPNs in advance.
The conversation occuring today will determine the amount of trust we can place both in the technology that surrounds us and the government that regulates it. Together we can find a better balance, end mass surveillance and remind the government that if it really wants to know how we feel asking is always cheaper than spying.
