Insurance DNS Filtering | Policyholder Data Protection

Why Insurance Needs DNS Filtering

Insurance companies are custodians of some of the most valuable personal data in any industry. A single policyholder record can contain Social Security numbers, medical histories, financial account details, property information, and beneficiary data. This concentration of sensitive information makes insurance carriers, brokers, and managing general agents prime targets for sophisticated cyberattacks.

The insurance industry's distributed workforce amplifies the challenge. Independent agents, field adjusters, underwriters working from home, and third-party administrators all access core policy administration systems from diverse network environments. Each connection represents a potential attack vector that traditional perimeter security cannot protect.

DNS filtering addresses these challenges by intercepting malicious domain requests at the network layer, regardless of where users are located. Whether an agent in a remote office clicks a restricted link disguised as a carrier portal or restricted content on an adjuster's laptop attempts to phone home, DNS filtering blocks the connection before damage occurs. With 90 million domains categorized across 58 categories, content risks are identified and neutralized in milliseconds.

Insurance Regulatory Compliance

DNS filtering supports compliance across state insurance regulations and data protection frameworks

NAIC Model Law Compliance

The NAIC Insurance Data Security Model Law (MDL-668) requires insurers to implement a comprehensive cybersecurity program with access controls, system monitoring, and content filtering. DNS filtering provides a documented technical control that satisfies multiple sections of the model law, particularly requirements for network monitoring and malicious code prevention.

State Insurance Department Requirements

Over 20 states have adopted cybersecurity regulations based on the NAIC model. New York DFS Regulation 500, which applies to many insurance entities, requires specific cybersecurity controls including monitoring and filtering of web traffic. DNS filtering directly addresses these requirements across all applicable state jurisdictions simultaneously.

SOC 2 Audit Support

Insurance companies increasingly undergo SOC 2 audits to demonstrate security controls to partners and clients. DNS filtering provides evidence for Trust Service Criteria related to logical access controls, system monitoring, and risk mitigation. Our audit-ready reports map directly to SOC 2 control objectives.

Policyholder Privacy Protection

GLBA and state privacy laws require insurance companies to protect the confidentiality of policyholder information. DNS filtering prevents data leakage through DNS tunneling and blocks access to domains known to host credential harvesting pages targeting insurance industry platforms and carrier portals.

Insurance-Specific DNS Filtering Features

Tailored capabilities for protecting the insurance industry's complex technology ecosystem

Agent Network Protection

Extend DNS filtering protection to independent agent offices and captive agent locations. Agents accessing carrier portals, quoting systems, and policy administration platforms are protected from restricted content and unsafe content regardless of their network environment or internet provider.

Claims Processing Security

Protect claims adjudication systems by blocking connections to fraudulent domains. Prevent claims adjusters from accessing compromised websites during investigations. Secure the data flow between insurers, TPAs, and claimants throughout the claims lifecycle.

Fraud Prevention Intelligence

Block access to domains associated with insurance fraud operations, including fake medical provider portals, staged accident coordination sites, and fraudulent repair shop networks. DNS-level blocking disrupts fraud rings before they can submit fabricated claims.

Remote Underwriter Protection

Secure underwriters working from home or satellite offices with DNS filtering that follows their device. Prevent access to malicious sites while allowing full access to rating engines, actuarial databases, and reinsurance platforms that underwriters need daily.

InsurTech Integration Security

As insurance companies integrate with InsurTech platforms and API partners, DNS filtering ensures that only approved third-party domains can communicate with your systems. Block unauthorized API callbacks and prevent compromised InsurTech partners from affecting your infrastructure.

Risk Assessment Dashboards

Visualize your organization's DNS web landscape with industry-specific dashboards. Track blocked restricted content attempts, unsafe content connections, and policy violations across your entire insurance operation. Generate reports for board presentations and regulatory filings.

Insurance DNS Filtering Use Cases

How insurance organizations deploy DNS filtering to protect operations and policyholders

P&C Carrier Protection

A national property and casualty carrier deploys DNS filtering across its home office, 30 regional offices, and 5,000 independent agent locations. After a spear-restricted content campaign targets agents with fake policy renewal notices, DNS filtering blocks the credential harvesting domains within minutes of detection, preventing any agent credentials from being compromised and protecting access to the carrier's policy administration system.

Health Insurance Claims Security

A health insurance company processes millions of medical claims containing protected health information. DNS filtering prevents claims processing workstations from connecting to data leakage endpoints, blocking attempts to tunnel PHI out through DNS queries. The insurer uses DNS logs to demonstrate HIPAA compliance to auditors and satisfies the NAIC model law's requirement for monitoring data leaving the network.

Auto Insurance Fraud Defense

An auto insurance company uses DNS filtering to block access to known fraud coordination websites and fake repair shop portals. When the SIU (Special Investigations Unit) identifies domains linked to organized fraud rings, those domains are added to custom block lists immediately. DNS filtering also prevents adjusters from inadvertently visiting compromised appraisal sites used to deliver unsafe content.

Reinsurance Network Security

A reinsurance broker secures its network connecting multiple carriers and cedents. DNS filtering ensures that treaty data, loss runs, and premium bordereaux are only transmitted through approved channels. By blocking unauthorized cloud storage and file sharing domains, the broker prevents sensitive reinsurance portfolio data from being accidentally or maliciously uploaded to unapproved services.
