Q & A

What is a VPN?

A VPN, or Virtual Private Network, is a tool that encrypts your internet traffic and hides your IP address and virtual location, ensuring better online privacy and security.

How does a VPN improve online security?

A VPN encrypts your internet traffic, making it difficult for third parties, including your ISP, to monitor your online activity. It ensures your data stays secure, even when accessing unsecure websites or apps.

Can a VPN help you bypass internet censorship?

Yes, a VPN allows you to access blocked websites by routing your internet traffic through a remote server, making it appear as though you're browsing from a different location.

When should I use a VPN?

You should use a VPN when you need to secure your online data, access blocked websites, use unsecure public Wi-Fi, avoid government surveillance, or use peer-to-peer file-sharing services.

What are the risks of using unsecure websites or apps?

Unsecure websites or apps can leak your personal data to cybercriminals or other third parties. Without a secure connection, your data is vulnerable to theft or unauthorized access.

How does a VPN protect you on public Wi-Fi?

Public Wi-Fi networks are inherently insecure. A VPN encrypts your traffic, preventing cybercriminals from intercepting or injecting malicious software into your device while you're connected to public Wi-Fi.

What is an IP address, and how does a VPN hide it?

An IP address is a unique string of numbers that identifies your device on the internet. A VPN hides your real IP address by redirecting your traffic through a remote server, making it appear as though you're browsing from a different location.

What is a VPN protocol, and why is it important?

A VPN protocol is a set of encryption standards that ensure secure communication between devices. Different protocols offer varying levels of security and speed, with popular options including OpenVPN, IKEv2, and WireGuard.

What is the difference between OpenVPN and WireGuard?
