Precision Control

1. Intelligent Firewall:

2. Real-Time Monitoring:

• Peer into the background of your device.

• Stay informed with per-app and per-connection analytics.

• Track your mobile and WiFi data usage with precision to see exactly where your bandwidth is being spent.

• High availability is built into our core, so your connection is there whenever you need it.

• Leverage the power of the WireGuard protocol.

• It is the gold standard for speed and security, providing a lightweight, modern way to encrypt your traffic while connecting to any VPN provider of your choice.

Safer Browsing

• Your device should serve you, not the trackers lurking behind your apps.

• Rethink your security, reclaim your privacy, and experience the internet on your own terms.

FAQ

Q: Is Rethink a standard VPN service?

A: While Rethink includes VPN capabilities, it is more accurately described as a versatile local firewall and DNS tool. It uses a VPN tunnel locally to inspect traffic, but it also allows you to configure or connect to any third-party VPN provider of your choice using the WireGuard protocol for enhanced privacy.

Q: Does using Rethink slow down my internet connection?

A: Not at all. In fact, because Rethink blocks ads and telemetry trackers at the DNS level, many users experience faster browsing speeds. Since your device spends less time loading unnecessary background advertisements, you will likely notice a snappier overall experience.

Q: Can I really control which apps are allowed to access the internet?

A: Absolutely. The intelligent firewall feature is designed to give you total command over your device's connectivity. You can easily toggle internet access for any app, ensuring that tools like calculators or file managers cannot send data to the internet without your explicit permission.
