Block AI Scraping
GPTBot, ClaudeBot, Firecrawl, and every other AI crawler treats your website as free training data. Perimeter Defense detects autonomous agents, blocks known scrapers, and protects your content from AI training — before a single page gets taken.

Most traffic never makes it past the checkpoint
Scrapers, crawlers, and LLM-training bots are stopped at the gate. Verified traffic — like search engines you actually want — passes straight through.
Real-time monitoring, with alerts your team will actually see
Every block, allow, and flag streams into a live feed — so you always know what's hitting your site and what's being stopped.

Every team with content worth protecting
From request to response — in four steps
Step 1
Fingerprint
Every incoming request is fingerprinted by user agent, headers, and behavior.
Step 2
Match
The fingerprint is checked against known scraper and LLM-training bot signatures.
Step 3
Decide
Verified crawlers pass through untouched. Everything else is flagged for action.
Step 4
Block & Alert
Malicious requests are blocked instantly and logged to your live monitoring feed.
Before you ask
Will this block search engines like Google or Bing?
No. Verified crawlers like Googlebot and Bingbot are allowlisted and always pass through — only unauthorized scraping and LLM-training bots are blocked.
Does this cover API endpoints, or just my website?
Both. Perimeter Defense watches web traffic and API endpoints for the same scraping and exfiltration patterns, including bulk-export and sequential-enumeration attempts.
