Our filtering databases are regularly refreshed

Around 20% of domains lapse every year, so a static snapshot quickly develops blind spots — threats slip through, and already-gone sites stay blocked. Every database tier includes scheduled refresh deliveries (quarterly through daily, depending on plan) to keep your filtering rules current with the live web.

Frequently Asked Questions

Should I choose the database or the API for web filtering?
If your filtering runs at the network edge — firewalls, DNS resolvers, secure web gateways — choose the Database. It lives on your hardware with sub-millisecond lookups and zero external dependencies. The API is better when you need per-request classification in cloud apps, browser extensions, or compliance tools without hosting data locally.
How frequently do filtering lists get refreshed?
Starter and Growth tiers refresh quarterly. Professional refreshes monthly. Enterprise gets weekly drops, and Ultimate receives daily delta files. Each update arrives via a secure download link you can automate with a cron job or CI pipeline.
How does API credit billing work?
One credit equals one URL lookup. Your monthly allotment resets on each billing date; unused credits don't carry over. If you consistently need more, upgrade your tier or buy a one-time credit pack.
Is there a long-term API commitment?
No. Every API plan is month-to-month. Cancel any time through your payment dashboard and you keep access until the current cycle ends.
Can I get a custom filtering database for my appliance?
Yes. We support white-label OEM embedding, custom category mappings, bespoke domain counts, and dedicated update SLAs. Email [email protected] with your use case and we'll scope a solution.
Which content categories does the database cover?
59 web-filtering categories span the full policy spectrum — Adult, Gambling, Malware, Social Media, Streaming, News, Education, and dozens more. On top of that, every record carries IAB v2 and v3 ad-tech categories (four tiers deep) plus 1,900+ audience personas.
