Azure AI Content Safety is Microsoft’s AI-powered service for detecting harmful content in both user-generated and AI-generated text and images. It runs as the built-in content filtering system for all Azure OpenAI and Foundry model deployments, screening both prompts and completions through an ensemble of classification models. The service is available as a standalone API and is deeply integrated into the Microsoft Foundry portal. It went through major expansion, adding prompt injection defense, hallucination detection, copyright protection, and PII filtering alongside its core harm-category classifiers.
In my opinion, Microsoft did a great job with this service. Over the past year, Azure AI Content Safety has matured from a simple harm classifier into a full guardrail platform, and this guide walks through what Azure AI Content Safety can do and how to configure it.
