Evidence and Source

  • Validate the identifying user-agent or signature against the operator documentation before creating hard allow rules.
  • Match `AccessibleWebBot` as a case-insensitive substring in HTTP user-agent logs. Review bot_aliases for alternate names or product labels. Use bot_http_agent for full user-agent examples when the client sends a longer browser-like string. Do not treat a user-agent match alone as proof of identity for allow-listing.
  • Uptime checks, managed website monitoring, synthetic tests, accessibility scans, or site-health reviews.
  • User-agent strings can be spoofed. For allow-listing or low-friction rules, pair the published identifier with operator documentation or cryptographic verification when available.
