Summary

Nonym is a privacy layer that sits between an app and SaaS services, detecting and replacing personally identifiable information before prompts reach supported providers. Its AI Proxy uses named entity recognition to identify items such as names, emails, phone numbers, addresses, SSNs, payment card details, and API keys. It substitutes structured tokens for detected information, then restores the values in the response before returning it to the app. The proxy supports OpenAI, Anthropic, Google AI, and OpenAI-compatible APIs, including streaming. Nonym states that processing adds under 20ms overhead. Audit logs can include detection counts, PII types, and confidence scores; a full audit trail is listed for paid plans. The pricing FAQ says managed Cloud token mappings stay in memory for the request and are not written to disk. Options include API, self-hosted, and web use, with private VPC and air-gapped deployments listed for Enterprise. Community is free for non-commercial self-hosting. Cloud costs $49 per month plus $0.50 per 10K requests; Self-Host License is $99 per month. Enterprise pricing is custom, starting ~$2,500/month.
