A VPN encrypts your browsing behavior, which can be decoded with the assistance of a key. Only your computer and the VPN know this key, so your ISP cannot perceive where you are browsing. Different VPNs use different encryption processes, but generally follow a three-step process: (Best vpn for gaming)
When you connect to the Internet, the VPN becomes active, working as a tunnel between you and the Internet. This tunnel cannot be identified by anyone, not even your ISP or any other third party.
Your device is now on the VPN's local network, and its IP address can be changed to an IP address provided by the VPN server.
You can now browse the Internet quietly as the VPN protects all your personal information.
There are various types of VPNs, but you're likely familiar with the three most significant types:
SSL-Based VPN
Often, not all employees of an organization have access to a computer that they can use to work from home. During the Covid crisis in the spring of 2020, many organizations faced the issue of not having sufficient hardware for their employees. In these cases, the use of a personal device (PC, laptop, tablet, mobile phone) is often employed. In such situations, organizations rely on an SSL-VPN solution, which is implemented through a corresponding hardware box.
The primary method typically involves an HTML-5 browser, used to request an organization's login page. HTML-5 browsers are available for almost any operating system. Access is secured with a username and password.
Site-to-Site VPN
A site-to-site VPN is essentially a private network designed to obscure private intranets, while allowing users of those secure networks to access each other's resources.
A site-to-site VPN is useful if you have multiple locations in your business, each with its own local area network (LAN) connected to a wide area network (WAN). Site-to-site VPNs are also useful if you have two separate intranets between which you need to send files without users on one intranet having to explicitly access the other.
Site-to-site VPNs are primarily used in large organizations. They are complex to implement and do not offer the same flexibility as SSL VPNs. However, they are ideal for ensuring communication within and between large divisions. (download best vpn for pc)
Client-to-Server VPN
Connecting through a VPN client is akin to connecting your PC to the company with an extension cord. Employees can access the company network from their home office through the secure connection and operate as if they were physically in the office. However, you need to have the VPN client installed and configured on your computer.
This means that the user does not connect to the Internet through their own ISP but rather establishes a direct connection through their VPN provider. Essentially, it allows you to bypass the initiation phase of the VPN process. So instead of using the VPN to create an encryption tunnel to hide the existing Internet connection, the VPN can automatically encrypt data before delivering it to the user.
This is an increasingly common type of VPN that is proving particularly useful for unsecured public Wi-Fi providers. It prevents access from third parties who may compromise network connections and encrypts data all the way to the provider. It also prevents ISPs from accessing data that, for some reason, remains unencrypted, and circumvents any restrictions on Internet access that the user may encounter (for example, if the government of that country restricts Internet access).
The advantage of this type of VPN access is greater efficiency and universal access to a company's resources. As long as an appropriate phone system is available, the employee can, for example, connect to the system with a headset and operate as if they were in the office at your company. For instance, an organization's clients cannot discern whether the employee is working at the company or from their home office. (Best vpn for android)
