XecGuard: Based on LoRA Adapter and Enhance Real-time Safety of Mainstream LLMs

Surpass other open-source models of similar scale, achieving protection comparable to large commercial models like OpenAI.

Maintain powerful defense without sacrificing the model's original capabilities.

LLMs equipped with XecGuard excel in LLM Red Teaming tests.

Strengthen Core Defense : XecGuard improves the model's overall security defense score by an average of 19.4%. When facing certain highly difficult attacks, defensive capabilities reach a maximum enhancement of 33.9%, demonstrating exceptional security resilience.

Superior Safety : XecGuard surpasses open-source models of similar scale including Llama 3B, Qwen3 4B, Gemma3 4B, and DeepSeek, even achieving protection comparable to large commercial models like OpenAI.

Powerful Without Compromise : XecGuard maintains powerful defensive strength without affecting the model's original capabilities. General capability evaluation (TMMLU+) slightly decreases by 0.9%, whereas MMLU evaluation scores actually improves by 4.2%.

CyCraft Guards Trustworthy LLMs

Next-Generation AI Firewall

According to the latest OWASP 2025 report, Prompt Injection is the top security risk for LLM applications.

XecGuard, the next-generation AI Guardrail safety module, instantly equips existing AI applications with robust malicious context defense. By blocking threats such as Prompt Injection, Prompt Extraction and Jailbreak attacks, XecGuard precisely enhances instruction adherence and provides active defense for enterprise AI.

Malicious Prompts Defense

XecGuard significantly improves instruction-following accuracy, detecting malicious contexts to effectively defend against Prompt Injection and Extraction attacks; therefore preventing AI from becoming a security vulnerability.

Instant Deployment, Safety Upgrade

Built on an advanced Guardrail architecture, XecGuard is compatible with common AI Chatbot interfaces. With instant deployment, safety protection can be upgraded immediately.

Strong Defense for Small Models

Even smaller models gain powerful resilience with XecGuard, achieving safety resilience comparable to large-scale commercial models, thereby delivering efficient and cost-effective AI security.

Outstanding Performance: XecGuard’s Industry-Leading Security Protection

In LLM Red Teaming assessments, XecGuard consistently outperforms other open-source Guardrail models such as Llama Guard and Prompt Guard with significantly higher security scores. By leveraging its stronger System Prompt instruction-following ability, XecGuard enables LLMs to effectively resist various Prompt Injection contexts that violate System Prompts.
