The full structure of the deliverable: cover and scope, an EU AI Act Annex IV slice, a SOC2-mapped findings table, a human attestation block, and a remediation appendix. Target name, dates, and finding literals below are redacted or fictional.
| Evidence pack ID | SAMPLE-EP-0000 |
| Target system | “Acme LLM Support Agent” (fictional, for illustration only) |
| System type | Customer-facing LLM chat agent with tool-calling access to an internal knowledge base |
| Scan date / report date | REDACTED |
| Scope | Prompt injection resistance, sensitive information disclosure, system prompt leakage, output handling. Limited to the OWASP LLM Top 10 categories exercised by the attack corpus; not a full penetration test, does not cover network/infra/non-LLM layers. |
| Prepared for | Compliance/procurement use: SOC2 audit evidence or vendor security questionnaire response |
| Prepared by | Ventrova, sentinel-scan-cli engine, human-reviewed |
What this pack is for. Maps a Sentinel Scan CLI run against a target LLM system to the control language used in SOC2 Trust Services Criteria and EU AI Act Annex IV technical documentation requirements, so it can be handed directly to an auditor or a customer's security review team without a follow-up call to explain what the raw scan output means.
What this pack is not. Not a substitute for a full SOC2 audit, a legal opinion on AI Act conformity, or a guarantee that undetected vulnerabilities do not exist. It documents what was tested, what was found, and remediation status as of the scan date.
The EU AI Act (Article 11(1), Annex IV) requires technical documentation covering nine areas. This pack directly evidences five of them from LLM-application-security testing; the remaining four are organizational documentation outside the scope of a security scan.
The scanned attack surface covers the interface between end-user input and the model's tool-calling and knowledge-base access layer. Established fact: the target accepts free-text user input that reaches the model with no observed input sanitization layer prior to inference. A factual observation from testing, not a full architecture audit.
Fifteen adversarial attacks were run, covering direct override, roleplay jailbreak framing, fake system-tag injection, translation-based obfuscation, base64 smuggling, hypothetical framing, authority impersonation, multi-turn setup, token smuggling, indirect tool-output injection, negation confusion, format-string exfiltration, and three disclosure/leakage vectors. Directly evidences the “foreseeable misuse and unintended outcomes” testing Section 3 requires. Human oversight measures beyond the tested attack surface (escalation paths, kill switches) remain the customer's responsibility to document separately.
The OWASP LLM Top 10-mapped findings table is the risk-identification input to a formal risk management process: each finding scored (SAFE/VULNERABLE), categorized by OWASP LLM risk class, given a severity and remediation status. Satisfies the “identification and analysis of known and foreseeable risks” component of Article 9. Risk acceptance and residual-risk sign-off remain the customer's own governance action.
The Remediation Status Appendix is designed to be re-run against the same attack corpus after each remediation cycle, producing a dated before/after record. The pricing coming soon tier includes a 90-day re-scan specifically to populate this section.
The re-attestation option (90-day re-scan) is the mechanism by which a customer shows an auditor a recurring, dated testing cadence rather than a one-time snapshot, what Section 9's “system in place to evaluate performance in the post-market phase” asks for.
Not covered by this pack (customer must source separately): Section 1 (general system description), Section 4 (performance metric appropriateness), Section 7 (harmonised standards applied), Section 8 (EU declaration of conformity). Organizational and legal artifacts, not security-testing artifacts.
Acme LLM Support Agent was tested against 15 adversarial prompts spanning 5 OWASP LLM Top 10 categories. 3 of 15 attacks (20%) succeeded in extracting sensitive information, all involving a literal secret-format string leaking into the model's response. 12 of 15 (80%), including all direct and role-play-style prompt injection attempts, were correctly refused.
Bottom line for a non-technical reviewer: the system resists direct jailbreak attempts but is vulnerable to indirect extraction techniques (narrative framing, direct system-prompt requests, markdown-based exfiltration). A common and specifically addressable pattern, not a sign of fundamentally broken security.

Signed by a named human at the customer organization, not by Ventrova or the scan tool. Sentinel Scan CLI and this pack provide test results; only the customer's accountable engineer or security owner can attest to remediation action and residual-risk acceptance.
Attestation I confirm that the findings in Section 4 of this Compliance Evidence Pack (Evidence Pack ID: SAMPLE-EP-0000) were reviewed by the undersigned, and that: [ ] All VULNERABLE findings have been remediated and re-tested, OR [ ] The following VULNERABLE findings remain open with documented compensating controls or accepted residual risk (attach rationale): ______________________________________________________ Name: ______________________________ Title: ______________________________ Organization: ______________________________ Date: ______________________________ Signature: ______________________________
In a real engagement this block is completed and signed by the customer after remediation review, then included as-is in the pack handed to the auditor or procurement contact. Ventrova does not pre-fill or sign this section.
| Finding | Status | Recommended fix |
|---|---|---|
| story_injection (LLM02) | OPEN (sample) | Add output-side filtering for known secret formats/patterns before the response leaves the model boundary; don't rely on system-prompt instructions alone. |
| prompt_leak_direct (LLM07) | OPEN (sample) | Treat the system prompt as non-secret by design; remove embedded credentials/internal URLs/secrets, move to a runtime-fetched, access-controlled store. |
| markdown_exfil (LLM05) | OPEN (sample) | Sanitize/strip markdown or link constructs from model output before rendering, or render as plain text where exfiltration via rendered links/images is a risk. |
Re-attestation cadence (Evidence Pack + Re-attestation tier (pricing coming soon)): a second scan against the same 15-attack corpus, run 90 days after remediation, with a diff against this baseline showing which findings closed. Feeds Annex IV Section 9; gives an auditor a dated, repeatable record instead of a single point-in-time claim.
Full raw sentinel-scan-cli JSON output is included as a separate machine-readable attachment in a real delivery (scan-results.json), timestamped and hash-referenced from the document, so an auditor can inspect the underlying attack/response pairs directly. Omitted from this sample; available on request.
This sample shows the exact shape of the deliverable. A real pack is generated from a Sentinel Scan run against your live or staging target, with your findings, your remediation appendix, and a blank attestation block for your own team to sign.
First 5 design partners who've run the CLI get the managed audit at pricing coming soon through September 2026, the floor of the pricing coming soon range. Mid a SOC2 AI addendum instead? See the auditor-ready evidence path →
