Nera Systems

An encrypted chat application that lets users query commercial LLMs over sensitive data such as customer, transaction, and patient records without exposing plaintext to the provider. It addresses regulatory exposure under GDPR, HIPAA and SOX, IP leakage from prompt retention, and lack of governance when data leaves the perimeter. It sells to IT and security teams, developers, and business users in regulated enterprises including financial services, insurance, and CPG. It is positioned as a layer that combines LLM intelligence with cryptography that survives compute, delivered as a SaaS application with client-side encryption and enterprise controls.
