Use of the Internet is now essential to global business, from shopping to banking to medicine to entertainment. SSL VPNs use public key cryptography to securely exchange encryption keys. IPSec connections use pre-shared keys on clients and servers in order to encrypt and send traffic back and forth. Two of the best-known and most popular secure network protocols used in VPN technology are Internet Protocol Security (IPSec) and secure sockets layer (SSL). Now that you know the answer to "What is VPN protection?" you might be curious about where it is most frequently used. The encryption process prevents anyone who may intercept the data between you and the server, such as a government agency or hacker, from being able to decipher its contents. Different VPNs use somewhat different encryption processes, but the general process includes tunneling and your data is encoded as it travels between your device and the server, which then decrypts the data and sends it on to your destination, such as a website. A VPN routes your device’s connection through a private server rather than the ISP, so that when your data reaches the Internet, it’s not viewable as coming from your device.Ī virtual network keeps your data private using encryption, which turns your information into unreadable gibberish only decipherable using a key, which is known to your device. VPNs use virtual connections to create a private network, keeping any device you connect to a public wi-fi safe from hackers and malware, and protecting sensitive information from unauthorized viewing or interception.

In the context of this VPN meaning, a VPN solution helps to protect against nefarious activities by creating an encrypted tunnel for all data you send and receive, unobserved by others. Data security can also be enhanced through VPN split tunneling, which enables users to route some traffic through their VPN and enable other traffic to retain direct access to the internet.īut in some cases, organizations may choose to install a VPN blocker to prevent employees from accessing sites that may hinder their productivity, such as social networking or shopping sites. A VPN solution helps to protect against these activities by creating an encrypted tunnel for all data you send and receive, unobserved by others.

What is a VPN capable of? A VPN hides a lot of information, including your browsing history, your IP address, your location, your endpoint devices (whether you're on a Windows computer or an an Android smartphone), and your overall web activity. Using a Wi-Fi network, especially one that is unsecured, means potential exposure of personal information to third parties, some of which may have malicious intentions. A VPN is one of the best tools for privacy and anonymity for a user connected to any public internet service because it establishes secure and encrypted connections. A VPN, meaning a virtual private network masks your Internet protocol (IP) address, creating a private connection from a public wi-fi connection.
