AI systems change how they behave once they are live, and the enterprises buying them cannot see it happen. They ask the vendor, and the vendor can only offer its own word. RAIDS is independent monitoring for the companies that build and sell AI. It watches what goes into an AI system and what comes back out, across large language models, tabular models and time-series models. It never touches model internals, training data or code, so it works with any system. It runs beside the system rather than in its path. That means it adds no latency and never changes a response; your system keeps every decision. On first use you name your system, then give RAIDS a baseline: past interactions you upload, or live traffic. Each sample then gets a label, a severity and the reasons behind it, in the dashboard and through the API. Detection runs in real time, with sub-100ms latency for tabular and time-series workloads and near-real-time detection for LLM-based systems. The record is organised against ISO 42001 controls. It gives providers and deployers the continuous monitoring evidence the EU AI Act asks for under Articles 26 and 72. A live "Monitored by RAIDS" seal shows a vendor's own customers that monitoring is running on a named system.
