What is DNS Firewall?

A DNS Firewall is a security service that sits between your device and the internet's DNS system. Every time your device tries to resolve a domain name (like example.com), the request passes through our filtering infrastructure first.

Think of it as a security checkpoint for every website you visit. Malicious domains, phishing sites, malware distribution servers, and trackers are blocked before your device ever connects to them.

Malware Blocking

Prevents connections to known malware distribution and C2 servers.

Phishing Protection

Blocks fake websites designed to steal your credentials.

Ad & Tracker Blocking

Stops invasive trackers and ads at the DNS level, system-wide.

Content Filtering

Enforce safe browsing with category-based content blocking.

02

How Does It Work?

RavenDNS operates on a simple yet powerful principle. Here's the journey of a DNS request through our system:

1
You type a URL or open an app

Your device needs to resolve the domain name to an IP address. This is called a DNS query.

2
Query arrives at RavenDNS

Instead of going to your ISP's default DNS, the query is sent to our Anycast infrastructure at the nearest edge node for minimal latency.

3
Real-time threat analysis

The domain is checked against your active DNS profile, custom allow/block lists, and our continuously updated threat intelligence feeds.

4
Allow or Block

If the domain is safe, we resolve it instantly. If it's malicious or blocked by your profile, we return a blocked response — the connection never happens.

DNS Profiles & Custom Lists

Profiles let you define exactly what gets blocked and what gets allowed. You can have multiple profiles and switch between them.

DNS Profiles

A profile is a collection of filtering rules. Each profile has its own allow/block lists and threat categories.

  • Create multiple profiles
  • Switch profiles from dashboard or client
  • Assign different profiles per device
Custom Lists

Define your own allow and block lists with specific domains. Override global rules for individual sites.

  • Block specific domains
  • Whitelist trusted domains
  • Bulk import domain lists
