Spoofing risk
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.

Notes

Amazon Kendra is listed in the Botcrawl directory as a security scanner from Amazon. The primary identifier for log review is amazon-kendra-.

Identification

  • User-agent pattern: amazon-kendra-
  • Family: Amazon
  • Type: Security
  • Kind: Scanner

Common use

Security scanning, malware checks, abuse prevention, compliance review, or vulnerability monitoring.

Verification and handling

Confirm the user-agent against server logs and use published operator documentation, IP ranges, reverse DNS, or other trust signals when available.

Directory guidance marks the risk level as Neutral and the blocking decision as Depends. Do not rely on the user-agent string alone because user-agent strings can be copied or spoofed.

Robots.txt handling: No.

Evidence and Source

  • Validate the identifying user-agent or signature against the operator documentation before creating hard allow rules.
  • Match `amazon-kendra-` 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.
  • Security scanning, malware checks, abuse prevention, compliance review, or vulnerability monitoring.
  • 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.
