Prompt Guard
Prompt Guard
Protect your LLM applications from jailbreaks, obfuscations, and malicious inputs with the most advanced guardrail engine on the market.

Block 100+ types of injections before they cause harm
Prompt Guard detects and blocks injection attacks in real time, using multi-layered analysis and the industry’s most extensive jailbreak database.


Prompt Injection
Identify attacks that unfold across several interactions, from roleplay exploits to context hijacking.
Indirect Injection
Detect prompt injections from external sources to prevent hidden prompts embedded in files or metadata.
Multimodal Injection
Detect and block hidden jailbreaks embedded in images, audio, or non-text inputs before they execute.
Code Injection
Prevent prompts that attempt to inject malicious code into tools, APIs, or downstream systems.
Industry leading performance
NeuralTrust is a high-performance security layer that outperforms all alternatives on the market in both execution speed and detection accuracy.

Context-aware enforcement
Stop users from launching repeated attacks
A unified runtime layer that intercepts and sanitizes every LLM request to block prompt injections and unsafe inputs.

Session memory
Analyze the full prompt history of each user to identify manipulation patterns over time (multi-turn attacks).
User blocking
Dynamically block malicious actors by IP, user agent, or request fingerprint.
Multi-language
Detect prompt injections in English, Spanish, and over 10 other languages with benchmarked parity.
