Screen untrusted text before your agent acts on it: prompt injection, data exfiltration, phishing and wallet-drainer intent. Pass raw content, or a URL we open from a residential IP so your agent never touches the trap. Returns a verdict, a 0-100 score, each finding with its matched snippet, and a sanitized copy of the text.
