Build AI fast. Keep it safe.
XecGuard is CyCraft's AI security Guardrail APIs, defending against LLM-targeted Prompt Attacks. XecGuard detects malicious conversational content in real time, delivering comprehensive LLM Safety protection for AI Agents and a wide range of AI application scenarios. It effectively blocks malicious inputs such as Prompt Injection, Prompt Extraction, and Harmful Content, preventing models from being misled into errors, deviating from their intended tasks, or producing harmful behavior—thereby enhancing system security and trustworthiness.
Multi-Model Fine-Tuning Technology
Instead of simple keyword filtering, XecGuard is powered by a collaboration of multiple fine-tuned small models. Each model performs semantic recognition and voting-based judgment for a specific security task. Compared to a single large model, this architecture demands lower computational costs and delivers faster response while maintaining high judgment accuracy.
Multi-Layered Threat Defense
XecGuard effectively blocks Prompt Injection, Prompt Extraction, and malicious Harmful Content, with deep semantic recognition capable of accurately uncovering underlying malicious intent—even when attackers use obfuscated encoding, role-play, or emotional persuasion tactics. It also ensures AI strictly adheres to the task scope defined by the System Prompt, preventing it from being led into unauthorized contexts.
Multilingual and Localization Advantages
XecGuard supports multilingual analysis in Chinese, English, and Japanese. In addition to accurately identifying semantic attacks in Chinese and Japanese, it also strengthens detection of Taiwan-specific PII formats (such as national ID numbers, addresses, and financial account numbers), meeting both cross-border and local compliance requirements.

XecART AI Red Teaming Assessment
XecGuard delivers comprehensive AI protection capabilities, integrating key modules:
General Prompt Attack Protection
Detect and prevent most attack behaviors including Prompt Injection, Prompt Extraction, and Evasion. Effectively block attackers attempting to override the model, expose system instructions, or bypass security mechanisms through obfuscation and encoding techniques.
System Prompt Enforcement
Ensure the AI system strictly follows the AI Agent task scope assigned by the enterprise (System Prompt Following), achieving true context-aware security and preventing the AI from being led into unauthorized contexts.
Content Bias Protection
Detect and mitigate outputs containing bias, harassment, or harmful stereotypes, ensuring AI aligns with corporate ethics.
Harmful Content Protection
Use semantic analysis to detect and prevent AI outputs that violate public morals or contain violence, hatred, or danger.
PII & Sensitive Data Protection
Protect privacy and prevent data leakage of enterprise AI, supporting Taiwan personal data, addresses, and plate numbers, ensuring AI does not expose personal or sensitive information.
Malicious Skills Protection
Detect whether AI Agent Skills and related file contents contain malicious or harmful elements, protecting the AI Agent from malicious skills.
Custom Policy Enforcement
Enterprises can customize Guardrail Rules or flexibly select from Default security modules based on their needs. Department-specific Safety Policies can also be designed by organizational tier, enabling enterprises to independently implement AI security governance.
Context Grounding Validation
Detect AI hallucination, verifying whether output strictly adheres to user-provided documents and approved RAG context.
