A VPN is supposed to protect your privacy. But many VPNs log your data, leak your DNS requests, or are owned by companies that sell your information.
How do you know which ones actually protect you?
We analyzed the privacy policies, technical implementations, and corporate structures of major VPNs. Here's what we found.
Watch: How VPNs actually protect (or fail to protect) your privacy:
The VPN Privacy Problem
What VPNs Promise
Hide your IP address
Encrypt your traffic
Prevent ISP tracking
Bypass geographic restrictions
What Many Actually Do
Log your browsing activity
Sell data to advertisers
Leak DNS requests
Share data with authorities
Owned by privacy-hostile companies
Key Privacy Metrics
1. Logging Policy
No Logs vs. No Logs
Many VPNs claim "no logging" but keep:
Connection timestamps
Bandwidth usage
IP addresses (even "temporary")
Browsing destinations
Session duration
What to Look For:
Proven no-log claims (court cases)
RAM-only servers (no disk)
Third-party audits
Jurisdiction considerations
2. DNS Leak Protection
DNS requests reveal your browsing even when using a VPN. Without proper protection:
Your ISP sees your DNS queries
DNS providers log your requests
Traffic can be traced
What to Look For:
Built-in DNS leak protection
Private DNS servers
IPv6 leak protection
WebRTC leak blocking
3. Corporate Ownership
Many VPNs are owned by companies you'd never trust with your data:
ExpressVPN: Owned by Kape Technologies (malware/adware company)
NordVPN: Owned by Nord Security (surveillance concerns)
Hotspot Shield: Owned by Aura (advertising company)
PureVPN: History of logging for FBI
What to Look For:
Independent ownership
Non-profit status
Open-source clients
Privacy-respecting parent companies

Testing Your VPN
DNS Leak Test
Connect to VPN
Visit dnsleaktest.com
Run extended test
Verify results show VPN server, not your ISP
IPv6 Leak Test
Disable IPv6 in system settings
Or use VPN with IPv6 leak protection
Test at test-ipv6.com
WebRTC Leak Test
Visit browserleaks.com/webrtc
Check for local IP exposure
Some leaks are normal; persistent leaks are problem
Kill Switch Test
Connect to VPN
Force disconnect VPN
Verify internet is blocked
Should auto-reconnect when VPN returns
VPN vs. Other Privacy Tools
When a VPN Helps
Using public WiFi
Hiding browsing from ISP
Basic geographic spoofing
Preventing targeted ads
When a VPN Doesn't Help
Against government surveillance (use Tor)
Against determined adversaries
If VPN itself is compromised
Against browser fingerprinting
Against account tracking
Complementary Tools
Tor: For maximum anonymity
HTTPS Everywhere: For encrypted connections
Privacy-focused DNS: For DNS privacy
Browser extensions: For tracker blocking
Setting Up Your VPN
1. Choose a Provider
Based on your needs from our analysis above.
2. Enable Security Features
Before connecting:
Kill switch: ON
DNS leak protection: ON
IPv6 leak protection: ON
Auto-connect on startup: Consider

The Honest Truth About VPNs
What VPNs Can Do
Hide browsing from ISP (if no leaks)
Encrypt public WiFi traffic
Mask IP for basic privacy
Prevent local network attacks
What VPNs Can't Do
Make you anonymous (use Tor)
Hide you from government (with warrant)
Prevent all tracking (browser fingerprinting)
Protect against all threats
VPN Limitations
Even the best VPN:
Sees your traffic (can log it)
Knows your IP when connected
Can be subpoenaed
May have vulnerabilities
Can't encrypt after exit node
Conclusion
A VPN is a useful privacy tool, but it's not a silver bullet. The privacy of your VPN depends on:
Company trustworthiness - Do they log?
Technical implementation - Do they leak?
Jurisdiction - What laws apply?
Your threat model - What are you protecting against?
For maximum privacy: Mullvad VPN or IVPN
For balance of privacy and features: Proton VPN
For simplicity: Mozilla VPN
Remember: The best privacy tool is the one you'll actually use correctly. Configure it properly, test it regularly, and understand its limitations.
Your VPN should protect you—not become another threat.
