Our new DOS policy detects and **blocks potential overloads by limiting the number of requests** per minute from each user. Customize the request threshold to match your security needs and **keep your system running smoothly**. ## Cost Harvesting Policy Manage your LLM’s cost efficiently with the new Cost Harvesting policy. The policy detects and **prevents excessive token use, helping avoid unexpected cost spikes**. Set a custom token threshold and control costs without impacting user experience. ## RAG Access Control **Secure your data with role-based access!** The new RAG Access Control API limits document access based on user roles, **ensuring only authorized users view sensitive information**. Initial integration supports **Google Drive**, with more knowledge bases on the way. ## Security Standards Mapping Every security policy now includes **OWASP, MITRE, and NIST standards mappings** on both policy pages and in the catalog. ## Enhanced Custom Policy Builder Our revamped Custom Policy Builder now empowers users with **"Simple" and "Advanced" configuration modes**, offering both ease of use and in-depth customization to suit diverse policy needs.
