Build Serverless DNS Filtering with UDP Gateway

Block malicious domains and secure networks for yourself or your customers without managing servers. DNS clients connect through Proxylity UDP Gateway and make queries handled directly by your AWS serverless resources, delivering enterprise-grade filtering at a fraction of traditional costs.

Proxylity doesn't deliver DNS filtering, but we provide the platform on which it can be built. Our example project on GitHub implements a simple blocking service your can use as-is or customize to meet your needs.

Key Benefits of Serverless DNS Filtering Built on UDP Gateway

🚀 Zero Infrastructure Management

Eliminate servers for hosting DNS software and filtering appliances. Connect DNS traffic directly to Lambda functions and other serverless AWS resources with automatic scaling.

🔐 Enterprise-Grade Protection

Block malicious domains, phishing sites, and unwanted content with customizable filtering policies powered by Lambda and DynamoDB at a fraction of traditional costs.

💪 High Performance

Handles thousands of DNS requests per second with consistent performance, tested with the largest domain blocklists under heavy load.

⏱️ Low Latency

Global architecture with points of presence around the world ensures minimal response times for every DNS query, even under heavy load.

💸 Cost-Effective

Asynchronous batching efficiently processes high query rates, reducing AWS API calls and dramatically lowering costs. Pay only for what you actually use.

🧪 Comprehensive Testing

Thoroughly tested with the largest domain blocklists and under high-load conditions to ensure reliable, consistent performance for enterprise deployments.

DNS Filtering Capabilities

Block Malicious Domains

Protect your organization from phishing, malware, and other threats by filtering DNS requests against comprehensive threat intelligence databases.

Redirect to Custom IPs

Implement sophisticated DNS policies with custom redirects to capture portals, internal resources, or security services.

Content Filtering

Enforce acceptable use policies by blocking access to inappropriate content categories using sophisticated filtering rules.

Custom DNS Rules

Implement organization-specific DNS rules and policies using the full power of AWS Lambda for complete control over DNS resolution logic.

How DNS Filtering Works with Proxylity

Proxylity routes DNS queries to your AWS resources, applying your custom filtering logic before returning responses - all without managing any DNS infrastructure.

Simply connect your DNS traffic to Lambda functions and DynamoDB tables. Configure filtering rules and let Proxylity handle the rest.

Technical Implementation Options

Custom Filtering Logic

Implement sophisticated domain filtering using AWS Lambda (or Step Functions) with full control over the filtering logic, response handling, and network policies.

DynamoDB Integration

Store filtering rules, blocklists, and domain categorizations in DynamoDB for global replication, high-performance lookups and easy updates at scale.

Comprehensive Logging

Destination multiplexing to capture DNS query logs to Firehose for security analysis, compliance reporting, and insights into network behavior patterns.

Real-Time Analytics

Stream DNS query data to analytics platforms for real-time monitoring, threat detection, and advanced threat hunting capabilities.
