What funda.nl was observed using to filter automated traffic, and what IP class legitimate large-scale data collection tends to require. Reviewed July 2026.
Determined from public HTTP response signatures (cookies, headers and challenge assets), reviewed July 2026. Providers change their stack over time - verify current behavior yourself. This is read-only technical reference, not a bypass guide.
A CDN, WAF or challenge layer is present. How aggressively it challenges automated traffic varies by configuration and route.
Clean residential or mobile IPs generally pass; datacenter ranges are the usual failure point.
Real Estate & Property Listings: Property portals treat listing data as licensed core IP, back it with enterprise bot management, and the vertical has a notable history of legal enforcement against scrapers. Beyond clean mobile or residential IP provenance, teams need legal review of listing-data licensing and terms before collecting at scale.
Akamai Bot Manager is an enterprise bot management product delivered through Akamai's global CDN edge platform, meaning detection runs at the edge server before a request ever reaches the site's origin. Because Akamai already fronts a large share of major e-commerce, travel, and classifieds sites, Bot Manager is one of the most commonly encountered enterprise defenses - in our registry it appears on 46 of the sites we checked, including marketplaces and classifieds such as eBay, AliExpress, Autotrader, Rakuten, and realestate.com.au. It is a managed, continuously updated detection layer rather than a single challenge page, and site operators tune how aggressively it responds.
Full Akamai Bot Manager referenceGoogle reCAPTCHA is Google's widely deployed CAPTCHA and risk-scoring service, embedded by site owners as a JavaScript widget or invisible script on forms, logins, signups, and other sensitive flows. It sits at the application layer as a challenge and scoring gate: the protected site receives a token or score from Google and decides server-side whether to allow, add friction to, or reject the request. It appears across many verticals, including sites in our registry such as Funda, Resy, and LinkedIn.
Full Google reCAPTCHA referenceResponsible use. This page describes the defense that exists, not how to defeat it. Always respect Funda's robots.txt, Terms of Service and applicable law, and collect only data you are permitted to. We do not provide site-specific bypass instructions.
Data Works is our done-for-you web-data service: you send the URLs and fields, we run the collection on real 4G/5G carrier IPs and deliver clean, QA-checked CSV / JSON / API data. Prefer to run it yourself? The same carrier IPs are self-serve from $4/GB.
Yes. As of July 2026, funda.nl was observed running Akamai (CDN/WAF), reCAPTCHA. A CDN, WAF or challenge layer is present. How aggressively it challenges automated traffic varies by configuration and route.
Clean residential or mobile IPs generally pass; datacenter ranges are the usual failure point. Whatever you use, respect Funda's robots.txt and Terms of Service and collect only what you are permitted to.
Your browser runs from a home or mobile IP with clean reputation; a scraper on a datacenter or heavily-reused IP is scored and blocked before the page renders. Same request, different IP verdict.
