+SecurityLingua is a safety guardrail model that uses the security-aware prompt compression to reveal the malicious intentions behind jailbreak attacks, enabling LLMs to detect attacks and generate safe responses. Due to the highly efficient prompt compression, the defense involves negligible overhead and 100x less token costs compared to state-of-the-art LLM guardrail approaches.

+To try **SecurityLingua** in your scenarios, you can use
+
+```python
+from llmlingua import PromptCompressor
+
+securitylingua = PromptCompressor(
+    model_name="SecurityLingua/securitylingua-xlm-s2s",

+
+For more details about SecurityLingua, please refer to [securitylingua readme](./experiments/securitylingua/readme.md).
+
 #### 3. **Advanced usage - Structured Prompt Compression:**
 
 Split text into sections, decide on whether to compress and its rate. Use `<llmlingua></llmlingua>` tags for context segmentation, with optional rate and compress parameters.
