What is LLM Prompt & Application Hardening?

LLM Prompt & Application Hardening secures AI applications through guardrails and policies that manage inputs, data access and outputs preventing misuse, unsafe responses and ensuring policy-compliant AI behavior.

Protection Against Prompt Injection & Jailbreaking

We design controls that prevent attackers from overriding system instructions, manipulating context or bypassing safety mechanisms.

Controlled AI Behavior

We ensure AI outputs follow defined policies, reducing hallucinations, unsafe responses and unintended automation.

Reduced Data Leakage Risk

We implement safeguards that prevent sensitive data exposure through prompts, memory, retrieval or tool usage.

Secure LLM Applications Need Multi Layer Defense

Our LLM Prompt & Application Hardening Covers

Policy-enforced prompts and instruction hierarchy

Guardrails for user input and model output

System prompt isolation and protection

Prompt injection and indirect prompt defense

Tool and function calling access control

Toxicity and abuse detection mechanisms

Logging, monitoring and anomaly detection

Rate limiting and abuse prevention

Our LLM Prompt & App Hardening Approach

At Cyberintelsys, we secure your LLM applications through prompt and application hardening, identifying and mitigating risks like prompt injection, data leakage and unsafe outputs to ensure reliable, compliant AI systems.

We identify AI use cases, application workflows, compliance needs and risk tolerance to define hardening objectives.

We analyze system prompts, user prompts, RAG pipelines, agent workflows, APIs and integrations to identify weaknesses.

We assess exposure to prompt injection, data leakage, hallucinations, unsafe automation and misuse scenarios.

Our experts design policy-enforced prompts, safety filters, moderation pipelines and access controls tailored to your AI use cases.

We implement retrieval hardening, source validation, least-privilege access and tool invocation controls.

We validate hardening effectiveness through adversarial testing and provide guidance for ongoing monitoring and improvement.
