XecGuard is a plug-and-play Guardrail security module. Without modifying the architecture, it instantly equips existing AI applications with robust malicious context defense capabilities, enhancing their instruction-following ability, blocking threats such as Prompt Injection, Prompt Extraction, and Jailbreak attacks.
Defending Prompt Attacks
Enhances LLM instruction-following accuracy, detects malicious contexts, counters Prompt Injection and Extraction, preventing model misuse or exploitation
Plug-and-Protect
Advanced Inference Guardrail architecture to extend enhancement on existing LLMs, supporting mainstream models with one-click security upgrades
Small Models Gain Enterprise-Level Defenses
Despite small model, once equip with XecGuard, the security resilience is comparable to large commercial-grade performance, delivering cost-effective AI protection
Even small models gain enterprise-level defenses, approaching large commercial-grade performance.
XecGuard delivers strong defensive capabilities while fully preserving the model’s core capabilities.
LLMs powered by XecGuard deliver exceptional defensive performance during LLM Red Teaming.
