CProtect DNS Features

Everything you need to run DNS on your own terms.

Ad & Malware Blocking

Block ads, trackers and malicious domains for every device using auto-updating block lists, regex filters and separate rules per client or subnet.

Encrypted DNS

Forward queries over DNS-over-TLS, DNS-over-HTTPS and DNS-over-QUIC to resolvers such as Cloudflare, Google or Quad9.

DNSSEC & Security

DNSSEC validation and zone signing, QNAME minimization, role-based access control and two-factor authentication.

Authoritative + Recursive

Host your own domains and resolve for your clients from one server, with Primary, Secondary, Stub and Conditional Forwarder zones.

Advanced Caching

Serve stale, prefetching, auto prefetching and a persistent cache keep lookups fast and dependable.

Web Console & API

Manage everything from a browser dashboard with live stats and query logs, or automate it through the API.

DHCP & Clustering

A built-in DHCP server, plus multi-server clustering to manage and replicate zones across instances from one console.

Runs Anywhere

Windows, Linux, macOS and Raspberry Pi, with an official Docker image for quick deployment.

Phishing, malware and tracker domains blocked at the DNS layer while safe traffic reaches the network
Cyber Security

Stronger cyber security, starting at the DNS layer

Almost every online connection begins with a DNS lookup. With CProtect DNS running on your own network, we add a protective layer that works before threats ever reach your devices.

  • Blocks threats before they connect. Malware, phishing and tracking domains are stopped at the DNS level using auto-updating block lists, for every device on the network.
  • Defends against DNS spoofing. DNSSEC validation rejects forged or tampered answers, so users are not silently sent to fake sites.
  • Keeps lookups private and untampered. DNS-over-TLS, DNS-over-HTTPS and DNS-over-QUIC protect queries from being read or altered in transit, and QNAME minimization shares less data upstream.
  • Controls who can change what. Role-based access control and two-factor authentication protect the admin console, and separate filtering rules can be set per client or subnet.
  • Gives you visibility. The dashboard and query logs help you spot suspicious lookups and understand what is happening on your network.
  • Keeps your data in your hands. It is self-hosted, so your DNS queries are not handed to a third-party provider.

DNS-level protection is one important layer of a defence-in-depth security approach.

Email Security Features

Multi-layer protection for every mailbox in your organization.

Spam & Virus Filtering

Multi-layer filtering blocks unwanted bulk email and virus-infected messages, and a cloud protection layer pre-filters mail before it reaches your server.

Phishing & Spoofing Defense

Helps prevent spoofed senders, phishing attempts and malicious messages from reaching your staff, along with denial-of-service and directory harvest attacks.

Advanced Threat Protection

With Advanced Threat Protection enabled, behavioral, heuristic and sandboxing technologies help stop ransomware, zero-hour and targeted attacks.

Outbound Filtering & Data Protection

Outgoing email is scanned too, so sensitive information is less likely to leak and your domain's reputation stays protected.

Email Encryption

Built-in email encryption helps keep confidential messages protected, without installing anything on users' computers.

Email Continuity

If your mail server goes down, incoming email is spooled safely in the cloud for up to 96 hours and delivered once service is restored.

Easy to manage: per-user settings and quarantine, granular policy control, and a simple web dashboard with reports.
