Safe and Private AI apps


Language models and chat apps that your organization can trust.  

Chatbots, language model apps, and AI features are being rapidly adopted across your organization, but you don't have a way to check or compare the security or data protection they offer.  

Let us help you.  

We identify and resolve privacy, security, and reputation risks in AI apps.   We build safe and protective LM apps, or help you test the apps already built by your organization.
