DeWall
Self-Hosted DNS Firewall & Management Platform
The Problem
Every device in your organization begins every digital interaction with a DNS query — yet in most networks, DNS is unmanaged, unmonitored and unprotected. This creates a massive blind spot that attackers exploit daily for phishing, malware delivery, data exfiltration and command-and-control.
DeWall changes that. It is a single self-hosted appliance that puts your organization in complete control of its DNS layer: securing it, seeing it and shaping it — without hiring a DNS specialist.
Built For
Organizations that need enterprise DNS security with SMB simplicity and full self-hosted ownership.
Key Capabilities
Private DNS
Your own recursive and authoritative DNS with full data ownership. Query logs never leave your infrastructure.
DNS Firewall
Network-wide blocking of ads, trackers, malware, phishing and admin-defined content via continuously updated threat feeds.
Per-User & Per-Location Policy
Rules that follow people, groups and sites — not just IP addresses — with time-based controls.
Full Visibility
Every query logged with user/device attribution. Live dashboards, searchable history and anomaly alerts.
Multi-Region Replication
One master, unlimited replica nodes across offices and regions. Every site resolves locally and keeps working if the WAN drops.
DNSSEC & Built-in PKI
Signed zones plus an internal certificate authority with ACME automation for trusted internal HTTPS — zero manual steps.
Deploys Anywhere
On-premises, cloud or hybrid: bare metal, VM, Docker or Kubernetes. No vendor lock-in.
