• company_lookup

  Newly registered look-alikes of a brand: names that entered the gTLD and .com/.net zones in the last 14 days and are a typo, a look-alike-character spelling (paypa1), the same name on another TLD, or the brand beside a lure word (paypal-login). Each with a risk tier and the reas…

• bot_verify

  Verify a crawler's identity: is this visitor (IP + user-agent) really Googlebot, Bingbot, GPTBot, ClaudeBot, Applebot, PerplexityBot..., an impostor using the name, another bot, or likely a person? Checked against each operator's published IP lists and forward-confirmed reverse…
