Data Delivery SLA
- Scheduled refresh deliveries, quarterly, monthly, weekly or daily depending on your plan
- About 300,000 new domains categorized every day, each checked again after a week and after a month
- Weekly delta files with the week's new and changed domains, daily delta files on request
- The whole database is refreshed every month, so changes in topic or status are picked up
- Delivery via secure download link (HTTPS), with no FTP and no unencrypted transfers
- Re-download available at any time during the license period
- Email notification sent when new updates are available
- File integrity verification via SHA-256 checksums provided with each delivery
The full rhythm is explained in update schedule and data freshness, and file fields and formats in database specification and delivery.
Data Quality
High
Categorization Accuracy
We recommend checking categorization quality against your own traffic patterns

The 20 million most visited domains cover 99.99% of web traffic and usage
Continuous
Quality Monitoring
Ongoing quality monitoring between scheduled releases, with every domain refreshed monthly

Availability & High Availability
Unlike API-based categorization services, the URL Categorization Database is deployed locally on your infrastructure. Once imported, your filtering operates with zero external dependencies.
- ✓ 100% uptime: determined entirely by your own infrastructure
- ✓ Zero network latency: all lookups are local
- ✓ No API rate limits: query as fast as your hardware allows
- ✓ No single point of failure: works even if our company is unreachable
- ✓ No data leaves your network: domain queries stay on your servers
- ✓ Predictable performance: no variable API response times
