VPN security and privacy in 2026: logs, DNS leaks, encryption, kill switch
What a VPN actually protects and what it doesn't: no-logs, encryption and protocols, DNS/WebRTC/IPv6 leaks, kill switch, and what to look for.
People often get a VPN "to open sites", but its other half is privacy and security. What a VPN actually protects (and what it doesn't), what no-logs, DNS leaks and a kill switch mean β without the marketing. The basics on choice and protocols are in the VPN-in-Russia 2026 guide.
What a VPN protects β and what it doesn't
It protects: your traffic from the ISP and public Wi-Fi (all inside an encrypted tunnel) and your real IP from sites. It doesn't replace: antivirus, anti-phishing common sense, or password hygiene. A VPN is channel privacy, not a free pass.
Logs and no-logs
The key question for any VPN is what it stores. "No-logs" means no traffic journals. Free services are the worst offenders β why paid is safer: free VPN: why it's risky.
Encryption and protocol
Channel strength comes from the protocol. Modern WireGuard/AmneziaWG use up-to-date cryptography; the difference between them is obfuscation, not protection. Details: protocol comparison, AmneziaWG vs WireGuard and VLESS Reality.
Leaks: DNS, WebRTC, IPv6 + kill switch
Even with a VPN you can leak: DNS queries outside the tunnel, your real IP via browser WebRTC, forgotten IPv6. Fix it with a proper client (DNS inside the tunnel) and a kill switch β it cuts the internet if the tunnel drops so traffic never falls back to the open network. Test at dnsleaktest.
VPN, banks and 2FA
A foreign IP can trip banks' and services' anti-fraud. That's their protection, not a hole β solved with split tunnelling: VPN and banking apps.
What to look for
