VPNs: What You Need to Know

A virtual private network (VPN) is a secure tunnel that connects two or more computers on the internet, allowing them to access each other as if they were on a local network. VPNs were formerly used by businesses to securely connect remote branches or connect roaming personnel to the office network, but they are now an important service for consumers as well, safeguarding them from assaults when they connect to public wireless networks. Given their significance, here’s everything you need to know about VPN for Linux. Here is something about free vs. paid VPNs

• While businesses set up their own VPNs using sophisticated network gear, consumers have a wide range of commercial and free VPN services to choose from.

• Free VPN services typically display advertisements, have a more limited range of servers, and connection speeds are slower due to overcrowding.
• Another disadvantage of free VPN servers is that the IP addresses they use are more likely to be blacklisted or filtered by numerous websites: Free VPN services are frequently misused by hackers, spammers, and other malicious individuals.
• Commercial VPN services operate on a subscription basis and are distinguished by the absence of download speed or data limits. Some of them also take pleasure in not keeping any logs that may be used to identify users.
• A few antivirus providers also provide VPN for Linux services, which could serve as a middle ground between free and more expensive commercial solutions, as consumers may be able to get better deals if they also have antivirus licences from such vendors.
