VPN Security Explained: How It Protects Your Data Online
A plain-language look at the security features that keep your connection private.
When you connect to a VPN, your device negotiates an encrypted session using protocols like OpenVPN or WireGuard. These protocols scramble packets with modern ciphers, making them unreadable to anyone intercepting the connection.
Most reputable VPN services also run their own DNS servers and include features such as a kill switch, which cuts internet access if the VPN drops. That prevents accidental leaks that could expose your real IP address or browsing history.
Choose providers that operate a strict no‑logs policy and undergo independent audits. Transparent privacy practices and up‑to‑date encryption ensure your VPN adds protection instead of risk.
