How LemReveal's 10-layer detection engine filters non-commercial traffic.
LemReveal's **ISP Auto-Detection Engine** is a 10-layer classification system that automatically separates commercial company traffic from ISPs, bots, VPNs, and other non-actionable visitors.
## The 10 Detection Layers 1. **ASN Classification** — Maps IP to registered organization type via Autonomous System Number 2. **Name Pattern Matching** — Detects ISP naming patterns ("Comcast", "BT Group", "Vodafone") 3. **Domain TLD Analysis** — Flags .net ISP domains vs. commercial .com/.io domains 4. **Cloud IP Range Exclusion** — Excludes AWS, GCP, Azure hosting ranges 5. **Residential IP Detection** — Identifies home broadband connections 6. **VPN/Proxy Detection** — Flags known VPN and proxy exit nodes 7. **Mobile Carrier Detection** — Excludes 4G/5G cellular traffic 8. **Bot & Crawler Filtering** — Removes automated bots, scrapers, and search engines 9. **Learned Pattern Engine** — System discovers new ISP patterns from your data over time 10. **Manual Override System** — You can promote or demote companies with an audit trail
## ISP Detection Log Every classification decision is logged for full transparency. Access the log from **Settings** → **Data Quality** → **ISP Detection Log**. Each entry shows: - Company name and domain - Detection layer that triggered the classification - Confidence score - Action taken (flagged, auto-classified, or overridden)
## Manual Overrides If a company is incorrectly classified as an ISP, you can override it: 1. Open the company profile 2. Click **Override ISP Classification** 3. Select "This is a real company" and provide a reason 4. The override is logged in the audit trail and persists through future scans
## Why This Matters Without ISP filtering, your dashboard would be polluted with Comcast, BT, Vodafone, and other residential broadband providers — companies that represent individual web users, not businesses evaluating your product. The 10-layer engine ensures your leads are real commercial companies worth your team's time.
