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. We index 8 real estate & property listings sites; the most common protection is Akamai (CDN/WAF), and 5 are rated hard. Reviewed July 2026.

Across 8 real estate & property listings sites in the registry, the most common protection is Akamai (CDN/WAF), followed by Kasada. Each site's observed stack is listed below and on its own page.
5 of 8 are rated Hard - large-scale public-data collection there tends to need real mobile carrier IPs and careful session handling. The rest are Light or Moderate. Difficulty reflects the network layer, not a bypass method.
Each entry is derived from public HTTP response signatures observed on the site's landing response, reviewed July 2026. A technology is listed only when a canonical signal was present.
Hand a hard target to Data Works for clean, QA-checked data, or run it yourself on real 4G/5G carrier IPs from $4/GB.
