Feature
DNS Policy Engine
Block or allow access at the DNS layer, before a connection is ever made.
Quick Summary
The DNS Policy Engine is the technical mechanism that enforces policy decisions at the DNS layer — blocking or allowing access before a connection is ever made — using encrypted DNS-over-HTTPS or DNS-over-TLS, without inspecting traffic content.
Business Problem
Enforcing policy by inspecting traffic content requires a VPN-style proxy that can see everything a device does — a level of technical access most organizations shouldn't need to grant just to govern internet access.
Feature Overview
The DNS Policy Engine is the technical mechanism that enforces the decisions made by the Policy Engine — it blocks or allows access at the DNS layer, before a connection is ever made, using encrypted DNS-over-HTTPS or DNS-over-TLS. It is the enforcement point; the Policy Engine (Site, Shift, Break, and Department Policies) decides what should be allowed.
Business Benefits
No traffic content inspection
Enforcement happens at DNS resolution, before a connection exists — there's no traffic content to inspect.
Encrypted, not plaintext
Enforcement runs over DNS-over-HTTPS or DNS-over-TLS, closing the plaintext gap most filters leave open.
Fails closed by default
If a device can't reach the policy engine, access fails closed rather than silently opening.
How It Works
DNS-layer enforcement
Policy is enforced at the DNS layer using encrypted DNS-over-HTTPS or DNS-over-TLS, closing the plaintext DNS gap most filters leave open.
Fails closed
Enforcement fails closed by default — if the device can't reach the policy engine, access fails closed rather than silently opening.
Isolated per tenant
Each customer runs on an isolated, dedicated tenant server — never shared compute or shared logs.
Deployment
No client-side proxy
There's no VPN-style client inspecting traffic — enforcement happens at DNS resolution.
Per-tenant infrastructure
Each customer's enforcement runs on dedicated, isolated infrastructure.
Works with every policy type
Enforces whatever the Policy Engine decides — Site, Shift, Break, or Department policy — without separate configuration.
At a Glance
Privacy
Like every Cyber Pulse capability, DNS Policy Engine runs inside the same privacy architecture: no message content, call logs, GPS location, photos, files, or keystrokes are ever collected — only domain-level enforcement metadata.
FAQ
What is the DNS Policy Engine?
It's the technical mechanism that enforces policy decisions at the DNS layer, blocking or allowing access before a connection is made.
Why enforce at the DNS layer?
Because it doesn't require inspecting traffic content — a policy decision can be made at domain resolution, before any connection exists.
Who benefits?
Organizations that want enforcement without granting a tool deep visibility into device traffic.
How is this different from the Policy Engine?
The Policy Engine decides what should be allowed, based on Site, Shift, Break, and Department rules. The DNS Policy Engine is how that decision is technically enforced.
When is this relevant?
On every enforcement decision — it's the mechanism behind every policy type Cyber Pulse supports.

- Runs over encrypted DNS-over-HTTPS or DNS-over-TLS, closing the plaintext DNS gap.
- Fails closed by default if a device can't reach the policy engine.
- Each customer runs on isolated, dedicated tenant infrastructure.
