AI & LLM Security Advisory

As organizations rapidly adopt AI and Large Language Models, new threat surfaces emerge at every layer. SentinalStrat provides specialized security advisory for AI systems — assessing, hardening, and monitoring your machine learning infrastructure against adversarial attacks and data exposure risks that traditional security programs weren't designed to address.

LLM Threat Modeling

Prompt injection, jailbreaking, and adversarial input assessment for production LLM deployments and RAG pipelines.

Training Data Security

Data poisoning attack vectors, training pipeline security reviews, and model supply chain risk assessment.

AI Governance & Red Teaming

Structured red team exercises targeting AI systems, aligned with NIST AI RMF and emerging regulatory frameworks.

Model Output Monitoring

Runtime monitoring for data leakage, PII exposure, and content policy violations in deployed AI systems.

AI / LLM Security Advisory & Expertise Services

A dedicated practice area built for organizations deploying AI at scale. From early architecture review through continuous adversarial testing — we cover the full LLM security lifecycle.

Attack Vector

Prompt Injection & Jailbreak Testing

Systematic exploitation of instruction-following vulnerabilities. We test direct and indirect prompt injection, goal hijacking, context manipulation, and multi-step jailbreak chains across production LLM endpoints and agentic pipelines.

  • Direct & indirect prompt injection
  • System prompt extraction
  • Multi-turn jailbreak sequences
  • Agentic tool-call hijacking
Data Security

RAG & Context Window Security

Retrieval-Augmented Generation systems introduce new PII leakage and data boundary risks. We assess embedding stores, chunking strategies, access controls, and context injection paths that could expose sensitive enterprise data.

  • Vector database access controls
  • PII leakage via retrieval paths
  • Cross-tenant data isolation
  • Context window overflow attacks
Supply Chain

Training Pipeline & Model Supply Chain

Adversarial attacks targeting the model lifecycle — data poisoning, model backdoors, and supply chain integrity. We audit training data pipelines, fine-tuning workflows, and third-party model provenance for embedded threats.

  • Training data poisoning analysis
  • Backdoor & trojan detection
  • Fine-tuning security review
  • Model SBOM & provenance
Inference Security

Model Inversion & Extraction Attacks

Evaluate the risk of proprietary model theft and training data reconstruction. We simulate membership inference, model stealing, and gradient-based extraction techniques to quantify your IP and data exposure.

  • Membership inference testing
  • Model stealing simulations
  • Training data reconstruction
  • API rate-limit bypass analysis
Agentic Systems

AI Agent & Orchestration Security

LLM agents with tool-use and autonomous decision-making introduce compounded risk. We assess agentic workflows, multi-agent architectures, tool integrations, and privilege escalation paths within orchestration frameworks.

  • Tool-call privilege escalation
  • Multi-agent trust boundary review
  • Autonomous action containment
  • LangChain / AutoGen hardening
Runtime Monitoring

Output Monitoring & Guardrail Validation

Continuous runtime detection of harmful outputs, guardrail bypasses, and policy violations in deployed AI systems. We design and validate monitoring architectures, safety classifiers, and incident alerting pipelines.

  • Guardrail bypass detection
  • PII & sensitive output alerting
  • Safety classifier validation
  • LLM observability design
