Virtual Private Networks or VPNs are not only important for the IT security of private users, but also and especially for the security of company networks. We tell you what you need to know.If there is a VPN connection, the data is transmitted between two or more computers on the Internet via a secure tunnel. The computers can access each other as if they were in a local network. You can choose the best ones from the Top 10 VPN services. They are Nord VPN, 5 Euro VPN, Surfshark, ExpressVPN, IPVanish, Private Internet Access, ProtonVPN, CyberGhost VPN, Ivacy VPN and PureVPN. You can choose any of them. But before that you will need to know what to expect from the VPN options.

VPNs for business and consumers

In the past , virtual private networks were primarily used by companies, for example to securely network specialist departments with one another or to provide field service employees with access to the company network. Today VPN is also an important service in the consumer sector, which is mainly used to protect itself against attacks in public WLAN networks.

And because the VPN service connection will certainly not lose its importance in times of increasing cyber threats , we have summarized the most important facts about the Virtual Private Network.

Virtual Private Networks: Advantages for data protection & IT security

Unsecured WLANs set for users Security risk why? Because the attackers who are in the same network “sniff traffic” or “hijack accounts” with the help of various techniques that do not run via the https protocol. Some WiFi providers also purposely inject ads into traffic, which in turn can lead to unwanted tracking.

Not to forget the governments, which in many parts of the world have taken over to systematically monitor users, to block visits to certain websites or to uncover attempts at “high treason”.There are practices that threaten freedom of expression and thus human rights.

After setting up a VPN connection, all traffic is via a secure server somewhere in the world directed. This protects your computer from local tracking attempts as well as from hacking attacks and also ensures that your actual IP address is not visible to the websites and services you visit.

VPN connections: not all are created equal

There are different VPN technologies with different encryption types. The Point-to-Point Tunneling Protocol (PPTP), for example, is very fast, but not as secure as IPSec, OpenVPN and other protocols that rely on SSL / TLS. With TLS-based virtual private networks, the type of encryption algorithm and the key length also play a decisive role.

It is worth knowing that the stronger the encryption, the greater the impact on the connection speed. Which VPN technology or encryption strength is the best varies from case to case and essentially depends on which one Data should be exchanged over the connection.

Geo blocking and firewalls bypass VPN

In the consumer area, VPN tunnels are also regularly set up to circumvent geo-blocking measures. They are there to limit online access to certain content to defined regions. The VPN service providers usually operate server farms all over the world, which in turn allows users to jump back and forth between the “required” IP addresses.
