At its homepage, immobilienscout24.de is protected by Unidentified WAF / bot protection. Typical approach to reach it reliably: Browser automation + residential IP. Difficulty is per-URL, so deep pages — profiles, listings, search — are usually harder.

Homepage-level, datacenter-IP snapshot, June 12, 2026.
This is a passive, homepage-level snapshot and can be inaccurate or out of date — anti-bot vendors update their models continuously, deep pages are usually more protected than the homepage, and a datacenter IP sees more challenges than a residential one. Treat it as a directional signal, not a guarantee.
The homepage is the open front door. On a real estate site the valuable pages behave differently — here's the plan to characterise immobilienscout24.de before you build.
