A VPN, or Virtual Private Network, is used to create a secure, encrypted connection between your device and another network over the internet[1]. This technology is designed to protect data transmission, keep online activities private, and allow access to restricted or region-locked content[2].
- Security on Public Networks: VPNs protect your data when using public Wi-Fi by encrypting your communications, making it much harder for hackers to intercept your information[3].
- Privacy and Anonymity: By routing your traffic through a VPN server and masking your IP address, a VPN makes it difficult for third parties, such as ISPs or websites, to track your online activities[3].
- Data Encryption: VPNs use encryption protocols (such as IPsec or TLS) to scramble your data, which prevents unauthorized access and enhances the confidentiality of your internet traffic[2].
- Bypass Geo-Restrictions: VPNs enable users to access global content by changing their apparent location. This feature is frequently used to access streaming services or websites that are blocked in particular countries[4].
- Remote Access to Networks: Businesses use VPNs to allow employees to securely access corporate networks and resources from remote locations, preserving both confidentiality and productivity[2].
- Prevention of Bandwidth Throttling: Because a VPN encrypts your traffic, ISPs are less likely to monitor your activity and reduce your internet speed based on usage type[4].
- Protection Against Censorship and Surveillance: In areas with limited internet freedom, VPNs help users communicate and access information securely without government or corporate monitoring[4].
