The Hazard Report is BigDataCloud’s consolidated view of IP address risk. It blends reactive signals (blocklists, past abuse evidence, known anonymiser detections) with proactive indicators such as the hosting likelihood model to assess the chance of non‑human or malicious use.
- Reactive signals: Third‑party abuse/blacklist checks and previously observed malicious behaviour, plus detectable VPN/proxy/TOR indicators.
- Proactive indicators: Whether the IP is in hosting/data‑centre infrastructure (no “eyeball” user), helping surface high‑risk traffic even without prior incidents.
Use this composite view to inform allow/deny rules, step‑up verification, throttling or rate‑limits, and strengthen zero‑day defence.
