A6-Indexer is a search engine crawler. Blocking it may affect your visibility in its associated search engine. Most publishers choose to allow verified search engine crawlers.

Centinel automatically detects A6-Indexer using behavioral fingerprinting. When detected, you can allow it, block it, challenge it with an interstitial page, or set a per-request licensing fee — all enforced in real-time with under 2ms latency.
