Enterprise AI Security & Adversarial Red-Team Audit
Execute a 20-point adversarial diagnostic across prompt firewalling, RAG vector ACL isolation, sandboxed agentic tool execution, signed safetensors supply chains, and bare-metal GPU enclave containment.
How does your document ingestion pipeline defend against indirect prompt injection hidden inside untrusted PDFs, emails, and HTML (e.g., 0.001pt font or white-on-white text)?
Auditor Focus: Standard DOM text extractors (PyMuPDF, pdfminer, Unstructured) blindly extract invisible 0.001pt and white-on-white text spans, allowing external invoices or resumes to hijack downstream RAG copilots.
Raw Text Stream Extraction (Unprotected)
Documents are parsed directly into chunks via standard PDF/HTML text extractors without font-size, bounding-box, or luminance verification.
Keyword / Regex Prompt Filter Only
Extracted text is scanned for static jailbreak phrases ('Ignore previous instructions'), which adversaries bypass using base64, multilingual, or semantic encoding.
Secondary LLM Guardrail Classifier
Retrieved chunks pass through an auxiliary guardrail model (e.g., Llama-Guard / NeMo) before context assembly, reducing but not eliminating optical spoofing.
Dual-Pass Viewport OCR & Luminance Attestation
Pre-chunking sanitizer strips any span <4.5pt, off-canvas, or >0.92 sRGB luminance delta and cross-attests DOM text against rendered raster OCR.

Enterprise AI Security, Adversarial Red-Teaming & Sovereign Architecture Audit
Logic42 Sdn Bhd (1656686-V)Logic42 • LETTER OF TRANSMITTAL
Pursuant to our engagement mandate, Logic42 Sovereign Engineering Practice has completed an independent, empirical 120-control architectural inspection and adversarial red-team campaign across your production Large Language Model (LLM) gateways, Vector RAG substrates, and autonomous Model Context Protocol (MCP) agent workflows.
Enterprise AI Security & Adversarial Red-Team Reference Standard
The Logic42 Enterprise AI Security & Adversarial Red-Team Audit evaluates sovereign AI deployments against OWASP Top 10 for LLM Applications (2025), MITRE ATLAS adversarial tactics, and NIST AI 100-2e2025. It benchmarks five critical attack surfaces: Prompt Gateway & Semantic Firewalls, RAG & Vector Substrate Isolation, Autonomous Agent & MCP Tool Sandboxing, Cryptographic Model Supply Chain (AI-SBOM), and Bare-Metal GPU Enclave & Kernel Telemetry.

| OWASP LLM01:2025 | Prompt Gateway & Visual Cross-Attestation | Zero-font/white-on-white hidden PDF directives hijacking RAG and Copilot instructions | Deploy dual-pass OCR vs. raw text visual attestation and sub-15ms semantic ingress firewall |
| OWASP LLM08:2025 | Pre-Retrieval Vector ACL & Lineage | Post-retrieval application filtering leaking restricted board & HR embeddings into top-K context | Enforce cryptographic pre-retrieval RBAC metadata predicates inside Milvus/Qdrant |
| OWASP LLM06:2025 | Agentic MCP Sandboxing & LOTA Defense | Autonomous agents executing arbitrary shell/SQL tools with long-lived static IAM credentials | Isolate tool execution in ephemeral Firecracker microVMs with Out-of-Band human cryptographic approval |

Frequently Asked Questions
What does the Logic42 20-Point Enterprise AI Security & Adversarial Red-Team Audit evaluate?
It evaluates 20 high-severity adversarial control checkpoints across 5 pillars: Prompt Gateway & Ingress Firewalls, RAG & Vector Substrate Isolation, Autonomous Agent & MCP Tool Sandboxing, Model Supply Chain & AI-SBOM Integrity, and Sovereign GPU Enclave & Kernel Telemetry—mapped directly to OWASP LLM Top 10 (2025), MITRE ATLAS, and NIST AI 100-2e2025.
How do indirect prompt injection and zero-font PDF exploits bypass traditional enterprise firewalls?
Traditional WAFs inspect network packets for SQLi or XSS signatures, not semantic natural language instructions embedded inside documents. When a RAG pipeline parses a PDF containing white-on-white or 0.1pt font instructions, those hidden commands enter the LLM context window as trusted system context, hijacking the model or triggering Living Off the Agent (LOTA) lateral movement.
What is the difference between the free 20-question online diagnostic and the Commissioned 84-Page Boardroom Monograph?
The free 20-question online diagnostic provides an immediate self-reported maturity score, 5-axis radar chart, and initial 8-page summary PDF. Organizations requiring formal board assurance or regulatory defense can commission a 4-to-6 week Principal Architect Red-Team Study delivering an 84-page hard-bound 4-Volume Monograph with 10,000-run Monte Carlo VaR modeling, live exploit PoC traces, cryptographic AI-SBOM attestation, and a fixed-cost 90-day BTO engineering Bill of Materials.
How does Logic42 secure autonomous AI agents and Model Context Protocol (MCP) tool servers?
We eliminate shared static service tokens and host-level code execution by binding every agent task to a cryptographic SPIFFE/SPIRE workload identity, running code/SQL tools inside ephemeral 15-second Firecracker microVMs, and enforcing Tetragon eBPF kernel policies that halt unauthorized socket egress in sub-millisecond time.
