Encrypts network traffic
People sharing a local network cannot casually read traffic traveling through the VPN tunnel.
Protect your connection.
Understand the limits.
A VPN encrypts traffic between your device and its servers and replaces your public IP. It can improve privacy on shared networks, but it cannot make every website or account safe.
Three useful protections
Changes the IP websites see
Sites normally see the VPN server’s public IP instead of your home connection’s IP.
Reduces reliance on public Wi-Fi
A VPN adds a protected tunnel when you must use a hotel, airport or café network.

VPN FAQ
Do I need a VPN at home?
It depends on your privacy needs and who you trust with connection data. A VPN changes who can observe parts of your traffic; it does not remove the need to trust a provider.
Does a VPN stop viruses?
No. A VPN protects a network connection. Device security, safe downloads and antivirus protection address different risks.
Are free VPNs safe?
Some may be limited but legitimate; others use unclear data practices. Check ownership, funding, limits and a clear privacy policy before installing one.
