VPN Detection: How It Works (and Where It Breaks Down)
Learn how VPN detection works — IP reputation, datacenter ASNs, behavioral signals — why VPN exits blur into proxies, and when not to block.
Field notes

Practical writing on proxy detection and IP intelligence: how proxy signals work, and how fraud, bot-detection, and security teams put them to use.
Proxy Detection False Positives: Why They Happen and How to Reduce Them
Why proxy detection flags real users — stale data, shared IPs, CGNAT — and how confidence-based, graduated responses cut false positives.
Click Fraud Detection With IP Data: A Practical Workflow
Learn how to detect click fraud with IP data: proxy status, network type, and recency checks, plus a click-enrichment workflow you can run weekly.
How to Detect Proxy-Driven Ad Fraud in Campaign Traffic
See how ad fraud operations route through proxies and how to audit campaign traffic by network type, confidence, and geography to find them.
Geolocation Databases vs. Proxy Detection: Two Different Questions
Geolocation databases answer where an IP is. Proxy detection answers whether it is a proxy exit right now. How the two data planes combine.
Proxy Detection Explained: The Complete Guide to How It Works
See how proxy detection works — the signals behind residential, mobile, and datacenter proxies, and how to act on the results. Read the guide.
Residential vs. Datacenter vs. Mobile Proxies: What Each Network Type Means for Detection
Compare residential, datacenter, and mobile proxies: where their IPs come from, how detectors classify them, and how to set policy. See the guide.
What Does an IP Confidence Score Actually Mean?
Learn what an IP confidence score means, how observation count, recency, and behavior shape it, and when to block or step up. Read the explainer.
Static IP Databases vs. Continuously Refreshed Proxy Datasets
See why proxy IP assignments rotate, how periodically refreshed IP databases lag, and what continuously tested data changes. Read the breakdown.
