Observed result

Subject: Zambo is live Hi [Name], I’m skipping the pleasantries. You are seeing this because your recent activity flagged a critical security risk that requires immediate attention, but the solution is now available. Zambo has launched. It is not a generic AI wrapper. It is a specialized security layer designed to intercept prompt injection, jailbreak attempts, and policy bypasses before they reach your core logic. The data from your recent scan is clear. Your system detected a malicious instruction override attempt with a 95% injection risk score. Standard filters missed the nuance. Zambo catches it. The platform provides real-time detection of jailbreak patterns, PII extraction attempts, and subtle prompt leaks. It does not guess. It analyzes the structural integrity of the prompt against a library of known attack vectors. When a threat is identified, Zambo blocks it and provides a detailed receipt of the exact pattern triggered. This is not about adding another tool to your stack. It is about closing the gap between what your current security measures claim to protect and what actually happens when an attacker probes your API. You do not need to change your infrastructure. Zambo sits upstream. It validates the intent. If the intent is malicious, the request never hits your expensive LLM tokens. If it is benign, it passes through with a trust score. The launch is limited. We are not scaling to handle unlimited traffic yet. We are focusing on precision. If you want to secure your endpoint against the specific threats identified in your logs, you need to test the live environment. [Link: Start Zambo Trial] This takes two minutes. No code changes required for the initial diagnostic scan. Best, [Your Name] [Your Title] Zambo

Provenance for every timeline entry

  • EXECUTED BY ZAMBOZambo ran the tool call itself.
  • OBSERVED VIA GATEWAYA Zambo gateway observed request and response bytes from the named external executor. Zambo did not run that external action.
  • LOGGED BY AGENTAn agent or local hook reported the action. Zambo attests that the record is unchanged since logging, not that the action happened as described.

Private agent reasoning, built-in client actions, and direct calls to unrelated MCP servers are not included unless an agent or gateway reports them.

What is an execution receipt?

An execution receipt is a public record of a reported AI agent tool call. Its byte commitment and provenance claim can be checked independently; neither alone authenticates the issuer. Read the canonical definition of an AI agent execution receipt.

What the receipt can and cannot prove

What is this?

Zambo's receipt store reports a tool call and records its result. The SHA-256 commitment covers the exact canonical bytes. The provenance label is bound to v0.4 receipt bytes when that check passes, but no pinned signature or trusted issuer key is checked. An anchor can timestamp a fingerprint; it does not authenticate the issuer.
