With FreeShield you can:
- Use unprotected networks (including public wifi hotspots) without compromising your security
- Prevent your mobile carrier or ISP from monitoring your traffic
- Protect your passwords, credit card details, and private messages through an encrypted VPN
- Avoid the annoying and disruptive injection of extra advertising into your internet experience

FreeShield works by directing all data traffic from you mobile device through a secure, encrypted VPN connection. This security layer prevents third parties from intercepting and reading your data. Note that FreeShield may analyze this information for product development purposes.
