Tell Necio what your app does and who uses it. It threat models your use case, then chats with your bot the way real people do, including the tricky, sneaky and off-topic questions you hope nobody tries.
Top frontier models read every answer and grade it like a strict teacher. Did it stay on topic? Keep secrets? Stay polite?
Run the same test every week. If your bot starts answering differently after an update, you hear about it first, and so does your security team. Necio can send every result straight to the tools they already watch.
Bad actors use free, openly available AI models to come up with questions that trick chatbots. Necio writes its tests with those same models, so your bot faces what it will actually face. Then the top AI models grade the answers.
“Because LLMs are inherently non-deterministic, prompt injection is not a problem you ‘solve.’ It’s a risk you continuously monitor.”
DeepSeek, Alibaba and the other open models only write test questions. They never connect to your app or your accounts. Necio sends every question itself.
Every AI model Necio uses, from the question writers to the graders at OpenAI, Anthropic and Google, runs under a zero-data-retention agreement. They do their job and store nothing.
