Job boards mix public listings with account-gated data, apply heavy fingerprinting and rate limiting, and the vertical has produced some of the most cited scraping litigation, so the legal boundaries are actively contested. Legitimate labor-market research needs clean IP provenance, restraint around logged-in surfaces, and careful terms and privacy review. We index 3 jobs & recruitment sites; the most common protection is Cloudflare (Bot/Challenge), and 3 are rated hard. Reviewed July 2026.
| # | Site | Protection observed | Difficulty |

| 1 | Glassdoor glassdoor.com | Cloudflare (Bot/Challenge) | Hard target |
| 2 | Indeed indeed.com | Cloudflare (Bot/Challenge) | Hard target |
| 3 | ZipRecruiter ziprecruiter.com | Cloudflare (Bot/Challenge) | Hard target |
Across 3 jobs & recruitment sites in the registry, the most common protection is Cloudflare (Bot/Challenge). Each site's observed stack is listed below and on its own page.
3 of 3 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.
