The Ghost Shield
A high-performance, edge-native firewall designed specifically to detect, categorize, and block AI scraper traffic before it hits your database.
How it Works
Zero Latency
Rules are fetched asynchronously and cached at the edge. The shield decision happens in microseconds, adding virtually zero overhead to your legitimate user traffic.
Fail-Open Architecture
We handle failures gracefully. If the Ghost API is unreachable, the shield automatically defaults to allowing traffic, ensuring your site never goes down due to our service.
Local Execution
The shield runs entirely within your own infrastructure (Vercel, Cloudflare, etc). No sensitive user data is ever sent to our servers for analysis.
Privacy First
We only analyze request metadata (User-Agent, IP, Headers). We do not inspect payloads, cookies, or PII. Logs are anonymized where possible.
Detection Logic
The Ghost Shield uses a multi-layered approach to identify AI bots and scrapers.
1. User Agent Pattern Matching
We maintain a massive, real-time database of known AI bot User-Agent strings. We match these against incoming requests using highly optimized Regular Expressions.
2. IP Range Verification (CIDR)
Sophisticated bots often spoof their User-Agent to look like Chrome. We cross-reference request IPs against known data center ranges (e.g., OpenAI, Anthropic, AWS Bot Networks) to catch these imposters.
3. Behavioral Heuristics (Coming Soon)Soon
For the most advanced enterprise protection, we analyze request velocity, path traversal patterns, and TLS fingerprints to identify headless browsers that attempt to evade detection.
