Think VPNs are only used for privacy? This is not entirely true. We invite you to read this article to discover 10 reasons to connect to a VPN, which you may never even know existed.
After blocking social networks and instant messengers, many users started using VPN (Virtual Private Network technology). This helps to connect to servers as if from another point in the world, which, in fact, makes the entrance to blocked resources possible. At the household level, these VPN functions are sufficient. But for more difficult operations, the OpenVPN system was developed. We will talk about this technology and its applications.
OpenVPN is a new open source implementation of VPN technology. The purpose of using OpenVPN is to create encrypted point-to-point, site-to-site channels.
What is OpenVPN used for? The technology makes it possible to establish communication between computers behind a NAT-firewall (the function of changing the IP address) without changing the system settings.
OpenVPN was introduced in 2001 by J. Yonan. The technology is released under a free license and is used on such operating systems: GNU / Linux, Apple Mac OS X, QNX, Microsoft Windows and others.
OpenVPN provides flexible VPN solutions to protect your data, whether it's online privacy, remote employee access, data security, or networking in cloud data centers.
Most often, OpenVPN is used to protect a private network. The technology allows you to encrypt data between computers on the same network.
The main factors affecting security are the OpenSSL library (although PolarSSL is already in use today) and the Transport Layer Security protocol. The encryption mechanisms associated with the OpenSSL libraries enable data to be encrypted and securely connected to servers.
There are several more reasons why OpenVPN is practical and safe to use:
Despite its undeniable advantages, OpenVPN has disadvantages. They mostly consist in the fact that manual configuration on some platforms takes a lot of effort and time. The internet speed also slows down due to strong encryption. Some may find it inconvenient to work with this system, since third-party applications are used to work.
