LLM Security & Red Teaming
We adversarially test large language models using multi-turn escalation, jailbreaking, and injection techniques, measuring attack success rates rather than binary pass and fail outcomes.
Your organisation has deployed AI, but has anyone tested it the way an attacker would? At BlockSecBrain, we deliver specialised security assessments for LLMs, GenAI applications, agentic systems, and AI-integrated infrastructure. We apply the same adversarial mindset that drives our VAPT practice, now purpose-built for the probabilistic, semantic attack surface of modern AI.
Six specialised assessment tracks covering every layer of your AI ecosystem, from model behaviour to deployment infrastructure and governance exposure.
We adversarially test large language models using multi-turn escalation, jailbreaking, and injection techniques, measuring attack success rates rather than binary pass and fail outcomes.
We test agent workflows for indirect injection, privilege escalation, tool misuse, and trust boundary failures that can trigger devastating blast radii.
Applications built on GPT, Claude, Gemini, or open-source models inherit both model vulnerabilities and app-layer risks. We test RAG flows, vector stores, APIs, and output handling.
We identify shadow AI deployments, unsanctioned model endpoints, and unmonitored data flows before they become compliance gaps or persistent leakage channels.
Third-party LLM providers, open-weight models, fine-tuning datasets, and ML dependencies all extend your attack surface. We assess provenance, integrity, and vendor risk.
Across web, mobile, cloud, IoT, automotive, and infrastructure engagements, we now layer in AI-enhanced analysis to accelerate recon and uncover complex flaw chains faster.
Our AI security assessments are aligned to the OWASP LLM Top 10, the industry standard for LLM vulnerability testing and GenAI application security evaluation.
Still the most dangerous class of AI attack, spanning both direct and indirect prompt manipulation paths.
PII leakage, system prompt exposure, and credential extraction through model outputs remain critical concerns.
Compromised model weights, malicious datasets, and vulnerable dependencies now sit directly in the AI trust chain.
Training or retrieval data can be manipulated to degrade performance, alter behaviour, or introduce backdoors.
Unsanitised model output passed into code execution, HTML rendering, or command paths can trigger downstream compromise.
Overly broad permissions allow AI agents to take autonomous actions that create security and financial risk.
Adversarial queries can extract proprietary prompts, business rules, and internal operational details.
Cross-user contamination, insecure vector stores, and poisoned retrieval pipelines can expose data and distort output.
Hallucination exploitation and AI-driven disinformation can create fraud, workflow disruption, and trust failures.
Token flooding, denial-of-wallet, and excessive inference cost attacks can quickly turn into operational issues.
A structured, repeatable process aligned to enterprise AI deployment realities and adversarial research workflows.
Identify LLMs, agents, integrations, and shadow AI deployments across your environment.
Map attacker paths, trust boundaries, data flows, and tool access specific to your AI architecture.
Run manual red teaming and automated probing to measure actual attack success rates.
Map every finding to the OWASP LLM Top 10 and deliver remediation layers with context.
Retest after fixes to confirm attack success rates drop below acceptable thresholds.
The threat landscape has fundamentally shifted. These themes explain why AI security needs real testing now, not after deployment.
Autonomous AI agents with tool access create a new threat class where prompt compromise can trigger file writes, API calls, and transactions without human awareness.
Teams deploy private or third-party models against corporate data without approval, creating significant hidden attack surface.
Threat actors now use AI to automate reconnaissance, scale phishing, and lower the expertise barrier for sophisticated attacks.
AI governance obligations are accelerating globally, pushing organisations to demonstrate AI security posture and control maturity.
Models, plugins, APIs, datasets, and business workflows all extend the trust chain and the blast radius of compromise.
Security teams that invest in AI-aware red teaming, anomaly detection, and guardrail verification can outpace opportunistic attackers.
