What is a VPN?
Learn the basics of VPN technology and how it protects your privacy online.
VPN basics explained
VPN stands for Virtual Private Network. It creates an encrypted tunnel between your device and a VPN server, hiding your online activity from your ISP, hackers, and websites you visit.
How encryption works
When you connect to a VPN, your data is encrypted using protocols like AES-256 (military-grade encryption). This scrambles your data so it's unreadable to anyone who intercepts it.
IP address masking
A VPN replaces your real IP address with the VPN server's IP. This hides your location and makes it appear you're browsing from the server's location, enabling access to geo-restricted content.
When to use a VPN
Use a VPN on public WiFi (coffee shops, airports), when accessing sensitive information, when streaming geo-blocked content, or whenever you want to maintain privacy from your ISP.
VPN limitations
VPNs don't make you completely anonymous. They can't protect against malware, phishing, or account compromises. They also don't hide activity from websites where you're logged in.
Warning: A VPN is one tool in your privacy toolkit - not a complete solution.
Setup Complete!
Your VPN should now be configured and ready to use. If you encounter any issues, check the FAQ below or contact your VPN provider's support team.
Frequently Asked Questions
Is using a VPN legal?
VPNs are legal in most countries, including the US, UK, and EU. However, some countries like China, Russia, and UAE have restrictions on VPN use. Always check local laws.
Will a VPN slow my internet?
Some speed reduction is normal due to encryption overhead and server distance. Quality VPNs minimize this impact - expect 10-20% speed reduction with top providers.
Can my ISP see I'm using a VPN?
Your ISP can see you're connected to a VPN server but cannot see what you're doing online. Some VPNs offer obfuscation features to hide VPN usage entirely.
