State & Local Government DNS Filtering | Municipal Network Security

Why State & Local Governments Need DNS-Layer Security

Municipal networks serve thousands of employees across departments ranging from public works to law enforcement. Each department operates different applications, handles sensitive citizen records, and connects to external agencies. Without DNS-level filtering, a single compromised device in the parks department can become a pivot point into the finance system or criminal justice databases.

Government agencies are the number one target for restricted content attacks, with an average remediation cost exceeding $2 million per incident. DNS filtering stops these content risks at the earliest stage by preventing connections to known malicious domains before any payload is delivered.

Our service integrates with existing government IT infrastructure, supporting Active Directory group policies, DHCP-based deployment, and agent-based filtering for remote government workers.

Government Cybersecurity by the Numbers

Understanding the web landscape facing state and local agencies

2,300+ Government restricted content attacks annually

$2.07M Avg. breach cost for public sector

58 Web content categories filtered

90M+ Domains in our content risk database

Government Compliance & Regulatory Challenges

DNS filtering helps meet critical regulatory requirements across multiple frameworks

CJIS Security Policy

Government agencies accessing FBI criminal justice information must comply with CJIS security requirements. DNS filtering provides the network access controls and audit logging mandated by CJIS Policy sections 5.5 and 5.10.

Election Infrastructure Security

CISA directives require election systems be isolated and protected. DNS filtering prevents voter registration databases and tabulation systems from communicating with unauthorized external domains.

State Privacy Laws

State-level data protection regulations require safeguarding citizen PII in government databases. DNS filtering blocks data leakage channels and prevents access to known restricted content infrastructure targeting government credentials.

NIST Cybersecurity Framework

Federal and state mandates increasingly require NIST CSF alignment. DNS filtering directly supports the Protect and Detect functions, providing continuous monitoring and access control at the network layer.

Acceptable Use Enforcement

Government networks must enforce acceptable use policies for both employees and public access points. Our 58 content categories enable granular policy enforcement across departments without complex proxy configurations.

Inter-Agency Data Sharing

When agencies share network resources or data feeds, DNS filtering ensures each connection meets the security baseline required by inter-agency agreements and state IT security policies.

Government DNS Filtering Use Cases

Real-world scenarios where DNS filtering protects municipal operations

Municipal restricted content Prevention

1

A county clerk workstation receives a fraudulent email with a link to a restricted content dropper domain. DNS filtering blocks the resolution before any unsafe content is downloaded, preventing a potential shutdown of all county services.

Library Public Access Filtering

2

Public library terminals provide open internet access to residents. DNS filtering enforces CIPA-compliant content restrictions on public devices while allowing library staff unrestricted access for research and cataloging operations.

Election System Isolation

3

During election season, voter registration and tabulation systems must only communicate with authorized state and federal endpoints. DNS filtering enforces strict allowlists, blocking all unauthorized outbound connections from election infrastructure.

Water Treatment SCADA Protection

4

Operational technology networks controlling water treatment and utilities require DNS filtering to prevent compromised SCADA systems from beaconing to restricted servers, protecting critical infrastructure from cyber-physical attacks.
