An enterprise buyer does not need a glossy statement that your AI is secure. They need a report they can evaluate: what was tested, what broke, what evidence proves it, what changed after fixes, and what risk remains. That is the practical job of an AI security assessment report.
This guide is the checklist we use when shaping a buyer-facing report for an AI product. It applies to LLM apps, RAG systems, tool-using agents, MCP-connected workflows, and AI-native SaaS products that are heading into procurement, security review, or a customer risk file.
If the buyer calls this a penetration test, clarify scope first. A standard appsec pentest and an AI red-team report answer different questions; the difference is laid out in AI penetration test vs AI red team. If the buyer has sent a questionnaire rather than asking for a report, start with AI security questionnaire for AI products.
The report has to answer six questions
A buyer-side security team is usually trying to answer a small set of questions under time pressure:
- What exactly was in scope?
- Which AI-specific failure modes were tested?
- What evidence proves the findings?
- How severe are the issues in business terms?
- What did the vendor fix, and what was retested?
- What risk remains after the assessment?
If the report does not answer those questions directly, it will not carry much weight. A long document with vague controls is weaker than a short document with precise scope, traces, findings, and retest status.
Section 1: executive summary
The executive summary should be written for a security reviewer, buyer, founder, or CTO who will not read every trace. It should not hide nuance, but it should make the decision clear.
Include:
- The product surface tested, in one sentence.
- The dates and environment tested.
- The number of findings by severity.
- The two or three risks that matter most.
- What changed after fixes and retest.
- A plain statement of residual risk.
Avoid:
- Claims that the AI system is “certified safe.”
- Generic language copied from a control framework.
- A green status without the scope that makes it meaningful.
Good executive summaries are bounded. They say, “We tested this surface under these rules and found these issues.” They do not imply coverage over products, environments, models, or integrations that were never assessed.
Section 2: scope and system map
Scope is the highest-leverage part of the report because it prevents both overclaiming and underclaiming. Enterprise review teams need to know whether the assessment covered the thing they are about to buy.
Document:
- Product areas and user flows in scope.
- Models, model providers, and versions where known.
- RAG sources, indexes, document classes, and retrieval filters.
- Agent tools, MCP servers, side-effecting actions, and approval gates.
- Auth, tenant boundaries, roles, and data classes.
- Environments tested: staging, production-like, production read-only, or local.
- Explicit exclusions.
For RAG and agent systems, draw the trust boundaries. Show where untrusted user input, retrieved content, tool output, and privileged credentials meet the model. Most serious AI findings appear where those boundaries are poorly enforced.
Section 3: threat model and framework mapping
The threat model explains what the testers assumed an attacker could do. Without it, severity becomes a matter of taste.
For AI products, common attacker positions include:
- Anonymous user.
- Authenticated user in one tenant.
- Malicious tenant admin.
- Malicious document author.
- Compromised upstream content source.
- Insider with limited access.
- External user steering an agent through indirect content.
Map the tested risks to named frameworks where relevant:
| Surface | Typical risks | Useful mapping |
|---|---|---|
| LLM app | prompt injection, data disclosure, unsafe output | OWASP LLM Top 10 |
| RAG | retrieval leakage, poisoned documents, citation abuse | OWASP LLM01, LLM02, LLM08 |
| Agent | excessive agency, unsafe tool invocation, memory poisoning | OWASP Agentic Security Initiative, MITRE ATLAS |
| MCP | broad tools, resource exposure, server trust, secrets | MCP-specific controls plus agent/tool risk mapping |
| Release process | no eval gates, no regression testing, weak monitoring | NIST AI RMF and internal SDLC controls |
Framework mapping is not a substitute for evidence. It gives the reviewer a shared vocabulary for the finding, but the report still has to show what happened in your system.
Section 4: reproducible findings
Each finding should stand alone. An engineer should be able to reproduce the failure, understand why it matters, and know what control would close it.
Include in every finding:
- Title and severity.
- Affected product area.
- Preconditions and attacker position.
- Attack narrative.
- Reproduction steps.
- Evidence: request traces, retrieval spans, tool calls, logs, eval rows, or screenshots only when a screenshot is the artifact.
- Business impact.
- Recommended fix.
- Framework mapping.
- Retest result or current status.
The evidence should preserve the shape of the failure while redacting secrets, tokens, private customer data, and exploit payloads that should not be redistributed. A trace that shows a retrieved untrusted span crossing into an instruction context is stronger than a screenshot of a bad answer.
Section 5: eval results and regression readiness
AI systems fail statistically as well as categorically. A single prompt-injection finding is a categorical failure. A drop in grounding from one release to the next is a measured regression. A useful report should cover both when the product depends on model behavior.
Include:
- What the eval set measures.
- How test cases were selected.
- Pass/fail thresholds.
- Judge model or human review process.
- Calibration notes for LLM-as-judge, if used.
- Baseline results before fixes.
- Retest or post-fix results.
- Known gaps in coverage.
For buyers, evals answer a procurement question that ordinary security testing cannot: how do you know the model behavior will not silently regress after launch? The strongest answer is a release gate backed by a fixed eval set and a retest history.
Section 6: fix plan and retest status
A report that ends at findings creates work but not confidence. The buyer wants to know whether the vendor can close the loop.
The fix plan should prioritize by risk reduction, not by convenience. Tie each item to the control that changes the system:
- isolate retrieved text as data, not instructions;
- enforce authorization inside retrieval, not only in the UI;
- narrow agent tools and require approval for side effects;
- pin and review MCP tool manifests;
- add structured logging for tool calls and retrieval spans;
- add eval gates for prompts, models, and retrieval changes.
Retest status should be explicit:
| Status | Meaning |
|---|---|
| Closed | The original reproduction no longer works and the fix evidence holds. |
| Partially mitigated | The direct path is reduced, but residual risk or alternate paths remain. |
| Open | The issue remains reproducible. |
| Accepted risk | The business accepted the risk with documented reasoning. |
| Not retested | A fix was claimed but not independently verified. |
Do not call a finding closed because a pull request merged. It is closed when the original attack path no longer works under the same evidence standard.
What buyers do not need
Cut these from the report unless they directly support the evidence:
- Long AI safety manifestos.
- Generic “we use encryption” language with no relation to the AI surface.
- Model provider marketing claims.
- Unscoped assurances that the product is safe.
- Severity counts without business impact.
- Screenshots that cannot be replayed or audited.
Enterprise buyers are not looking for theater. They are looking for a defensible reason to approve, request fixes, or reject the risk.
How this relates to Phixe services
If you need the artifact, start with the AI Security Review Before Enterprise Procurement. If the buyer has not yet asked for a report but your team wants to find the gaps first, start with the AI Product Readiness Assessment.
