What’s New

Version 2.2.1

A minor update that fixes a bug that snuck past final testing when trying to export a .mobileconfig or .sswan configuration file.

If you are enjoying Guardian Firewall + VPN, we’d like to encourage you to rate or review our app in the App Store.

New in 2.2:
It’s finally here! Introducing Exceptions; a powerful feature we are proud to bring to the Guardian Firewall experience.

Exceptions: This feature provides even more configuration of our Firewall + VPN service to cater to your specific needs. Can’t re-watch Mandalorian episodes because Disney + doesn’t play well with Guardian? Now, with exceptions, you can!

The Exceptions feature was created to allow users to precisely define what traffic should be excluded from being filtered by our firewall servers while still providing firewall and VPN protection to all other traffic. If you have noticed a website or application on your iOS device is acting up or simply won't load while Guardian is connected, this new feature solves this issue by allowing you to simply add the website URL or application to the Exceptions list. Once added, these specific apps or websites will be excluded from being routed through our firewall to create an uninterrupted experience all while continuing to protect and filter all other traffic as you use your device.

Enter any hostname you wish to exclude or search for the name of an iOS app in our database with over 14,000 analyzed applications. Our app database continues to be regularly updated to ensure the best possible compatibility.

For Pro users, we have completely overhauled the interface to generate additional VPN credentials, and added more sharing capability to share VPN credentials to other mobile OS using a .sswan StrongSwan compatible file.

This update also includes the ability to reset the Alerts menu counts to zero. It is like a day trip odometer for your app allowing you to quickly reset everything, as if you had just downloaded our app for the first time.

The final solution

I’ve tried most of the major VPNs around. Guardian is the o only one you can really forget about. Just turn it on and never goes back to it. It just works. If you’ve tried a few VPNs you know what I’m talking about. There’s no way you don’t have to access it at least once every other day. You also get a firewall for your iPhone. I really recommend it. Can’t wait to have Guardian available to macOS too!!

It’s works Well!

I downloaded the app a few days ago thinking it was some video game. However, when I start the app up I realized it was a VPN. I decided to keep it and it’s safe to say it does work. It blocks every tracking program and tells you who’s been tracking you. It also does a decent job as a VPN. I decided to keep it and I suggest you check it out. The app is neat and easy to use. 10/10!

Uses Legacy VPN Technology

I really love the firewall, but the VPN, which still does not use WireGuard, is way too slow. If you’re paying for a huge connection to wherever it is you use your phone, you don’t want to severely limit it with an outdated legacy VPN. Guardian is a firewall pioneer, it has an incredible firewall for mobile devices that is par none, but it is a VPN dinosaur. I heard Guardian will improvement WireGuard in 2021. Until then, I just won’t use the app. When I can verify that it’s good to go and that the VPN is very fast, I’ll become a happy subscriber.

Developer Response ,

Thanks for your feedback! We are indeed taking some time to do things right when it comes to WireGuard support. Out of the box, some changes are needed in order to deliver a WireGuard-secured experience which also fully respects user privacy.
