IPQS Proxy Detection API vs MaxMind IP Geolocation API: Side-by-Side Comparison (2026)

IPQS Proxy Detection API

Startups and SMBs blocking fraudulent access at scale will see immediate ROI from IPQS Proxy Detection API; its 25+ data point IP reputation scoring catches residential proxies and datacenter botnets that generic blocklists miss. The API handles bulk CSV uploads for batch enforcement and integrates directly into authentication flows, covering the PR.AA and DE.CM functions that actually prevent account takeover. Skip this if you need a unified threat platform; IPQS does one thing, detection, and doesn't handle response or recovery.

MaxMind IP Geolocation API

Security teams that need to block abuse and fraud at scale should pick MaxMind IP Geolocation API for its proxy and anonymizer detection, which catches VPN traffic and datacenter IPs that other geolocation services miss entirely. The tool covers all four NIST CSF 2.0 asset identification and risk assessment functions, and its confidence scoring lets you set decision thresholds rather than treating all matches as equally reliable. Skip this if you need domain reputation or file hash intelligence; MaxMind is IP-only, and pairing it with threat intel platforms for richer context is table stakes.
