Regrettably, there is no ideal free VPN add-on for Chrome — utilizing a complimentary service carries privacy concerns, regardless of positive feedback. The majority of free VPNs offer weak security, impose usage restrictions, and slow down your connection. Certain free VPN services even generate income by selling your information to unreliable third parties, jeopardizing your safety.
Reputable VPNs for Chrome like OneVPN also offer additional features that might be useful. For example, the OneVPN Chrome extension automatically
blocks WebRTC — a protocol that could leak your IP. Another neat feature is Threat Protection — it blocks ads and protects you from entering malicious websites. You can control both in the settings panel of the extension.
