About Secure DNS & Firewall

DNS Firewall encrypts all DNS queries across all networks to ensure secure DNS queries and protect your privacy. With customized rules, it also helps protect against certain phishing and malware attacks, blocks ads and trackers, and provides a safer and cleaner network environment.

## Features

### Security

DNS Firewall offers a DNS over HTTPS (DoH) service to immediately protect your DNS privacy and safeguard against DNS manipulation, a cyber attack that can block access to news sites, social media platforms, and messaging apps.

### Customizable Firewall

You can add domains to the block list, including subdomains, and customize it to fit your needs.

### Predefined Blocked Categories

We maintain and update predefined blocked categories, such as known malicious and phishing domains, several times a day to keep the block list data up-to-date.

### App/Service Blocking

You have the option to block selected apps and services.

### Your DNS query history

- Offers clear insights into your network queries. You can block or allow domains with a single tap.
- Displays the domains you're visiting, the blocked domains, and the reason for the block (e.g., ad, malicious).
- Shows the most recent DNS queries on your device via a timeline.
- DNS query history is private and can only be accessed by you.
- Can be turned off, in which case the server won't save any query data.
