The system blocked an instruction override trying to leak confidential prompts and API keys.\n\nThis isn’t a hypothetical drill. It’s a live, semantic pattern match caught by our 18-rule engine. The receipt confirms the blocked vector, but it doesn’t validate the output’s correctness—it proves the saved bytes remained unchanged during the attack.\n\nWe’re not selling you a generic firewall. We’re giving you a semantic layer that understands intent, not just syntax.\n\nRight now, Zambo’s free tier is unlimited. You have 19 calls left on your daily limit, but you’re not paying a cent for this protection.\n\n**Your next step:**\n\nClick here to view the full analysis of the blocked threat: https://zambo.dev/run/a6e7bef6-cbd9-41f3-b8a9-3fb2de386814\n\nThis is a prospect-level preview. We haven’t sent outreach or confirmed customer status. We’re just showing you what’s possible when your AI infrastructure has a semantic immune system.\n\nIf you want to see how this works on your own endpoints, the API docs are live at https://zambo.dev/api/prompt-shield.
