Do I need a VPN at home?

It depends on your threat model. A VPN can add encryption against ISP visibility and local network risks, but HTTPS already protects much web traffic. Many users prioritize VPNs for travel and public Wi-Fi.

Is a VPN the same as antivirus?

No. Antivirus detects malicious software. A VPN encrypts network traffic. Both solve different problems.

What Is a VPN and What Does It Actually Protect?

By DexterVPN Editorial Team

A virtual private network (VPN) routes your internet traffic through an encrypted connection to a remote server operated by a VPN provider. This helps protect data on untrusted networks and hides your home IP from websites you visit, but it does not stop account logins, malware or all forms of tracking.

VPN stands for virtual private network. When you connect to a VPN, your device builds an encrypted tunnel to a server run by the VPN provider. Traffic exits to the public internet from that server, so websites and apps typically see the server's IP address instead of your own.

What a VPN protects

Traffic content between your device and the VPN server while the tunnel is active
Some metadata visible to your local network operator on public or shared Wi-Fi
Your real home IP address from sites that only see the VPN endpoint

What a VPN does not protect

Phishing emails or fraudulent login pages
Malware already on your device
Identity you reveal by signing into Google, banking or social accounts
All third-party trackers — especially after you authenticate on a site
