Essential Security Features

Kill Switch

Automatically blocks internet access if VPN connection drops, preventing data leaks. Always enable this feature for maximum security.

DNS Leak Protection

Prevents your DNS queries from being sent outside the VPN tunnel, which could reveal your browsing activities to your ISP.

No-Logs Policy

Ensures the VPN provider doesn't store records of your online activities, connection times, or other identifying information.

Security Best Practices

Do:

  • • Always enable the kill switch
  • • Use two-factor authentication on your VPN account
  • • Regularly update your VPN app
  • • Test for DNS and IP leaks periodically
  • • Choose servers closer to your location for better speed

Don't:

  • • Use free VPNs for sensitive activities
  • • Log into personal accounts on public networks without VPN
  • • Disable security features for convenience
  • • Use VPNs based in surveillance alliance countries
  • • Share your VPN account credentials

Testing Your VPN Security

Regular Security Checks:

IP Leak Test: Visit whatismyipaddress.com to verify your IP is masked
DNS Leak Test: Use dnsleaktest.com to check for DNS leaks
WebRTC Leak Test: Test for WebRTC leaks that can expose your real IP

Advanced Security Considerations

Multi-Hop VPN

Routes your traffic through multiple VPN servers for enhanced anonymity, though this may impact speed.

Tor over VPN

Combines VPN with Tor network for maximum anonymity, ideal for journalists and activists in restrictive regimes.

Split Tunneling

Allows you to route some traffic through VPN while keeping other traffic on your regular connection.
