everything you must have to protect our privacy

For more security measures we take, there are always going to be small gaps that will put our privacy at risk when we connect to the Internet. Therefore, if we want to connect safely through the Internet and be sure that no one, not our ISP or any Internet company, has access to our data and follows us through the Internet, one of the best options we can take is make use of a VPN.

How a VPN protects our privacy

A VPN connection it is, broadly speaking, a private and encrypted connection between us and an intermediate server owned by the company that provides this service. The traffic is encrypted before leaving our computer and travels in a fully encrypted way to the VPN server.

As the connection is encrypted at all times, neither our ISP nor any intermediate company can know what the traffic we are sending or receiving contains. This is also very useful (rather, essential), for example, when we connect to the Internet from a bar or an airport; from public networks. Our traffic is encrypted before leaving the PC, so if there is a sniffer capturing the traffic, it will not be able to know what it contains.

When traffic reaches the server, it is decrypted, analyzed, and forwarded to its destination. During this process, the entire identity of the person who sent the package is hidden, such as their IP, their country of origin, etc. The traffic is completely anonymous, and only the data (IP, country, etc.) of the VPN is disclosed.

When the destination server responds, the reverse process occurs. The traffic is sent to the VPN server (since it is who has sent it), and this encrypts it and sends it to us safely to our computer. Without fissures.

Other uses of a virtual private connection

In addition to protecting our privacy when connecting to the Internet, VPN networks have many other uses. For example, one of the best known is the possibility of hide our country of origin and to be able to supplant it by the one that we want. In this way we can skip any geographical restriction and visit any website without problems.

In the same way we can skip any other restrictions. For example, if our network or our ISP is blocking P2P traffic, thanks to the VPN we will be able to download safely and without problems from this network. As the traffic is encrypted, it will not be known that it is P2P traffic. The same happens when any other port or protocol is blocked.

Finally, as we have already explained, these connections help us to protect our security when we connect to the Internet from public networks, in bars, airports, etc. Traffic encryption prevents any sniffer from tracking us.

What a good VPN should have

Today we can find a large number of VPN services on the net. However, not all of them protect our security in the same way, and using some of them can be even dangerous.

A Reliable VPN and sure, like Surfshark, it must have a series of characteristics that allow us to be sure that our traffic travels safely through the Internet.

One of these characteristics is that it is a service of payment. More or less cheap, but paid. This secures a source of income for the company and ensures that it will not use our data to profit by selling it to third parties, something that free VPNs often do. Furthermore, a good VPN must be compatible with all types of operating systems, browsers, and devices so that our traffic is always assured.

Privacy is very important. Therefore, the more countries our server has to go online through them, the better. The encryption of point-to-point connections is very important as well, so we must look for algorithms that are impossible to break, such as AES-256-GCM that Surfshark offers us. The use of secure protocols, such as IKEv2 / IPsec, it is also essential to preserve our privacy.

The more security measures the VPN offers, such as Private DNS and safe, Multi-hop to make it difficult to track or the possibility of using your network for P2P downloads, we will be more secure and private when we browse the Internet through this server.
