Hey HN, I built SafeKey because I was handling patient data as an Army medic, then doing AI research at Cornell. Every time we tried to use LLMs with sensitive data, something leaked. Existing tools only covered text at ~85% accuracy. Nothing worked across modalities. SafeKey is an AI input firewall. It sits between your app and the model, redacting PII before data leaves your environment. What we built:

PII Guard: 99%+ accuracy across text, images, audio, video AI Guard: Blocks prompt injection and jailbreaks (95%+ F1, zero false positives) Agent Security: Protects autonomous AI workflows RAG Security: Secures retrieval-augmented generation pipelines

Sub-30ms latency. Drop-in SDK for OpenAI, Anthropic, Azure, AWS Bedrock. Runs in your VPC or our cloud.

Would love feedback on the approach. Happy to answer questions.

Thanks, Sukin

I’ve spent the past five years working in content moderation.

In my opinion, the real gap in the market isn’t “better safety models”. it’s turn-key orchestration platforms that provide:

- A web portal for manual moderation and data-labeling workflows

- Multi-tier moderation checks (e.g., if a keyword is detected, escalate to an LLM)

- Simple integration of custom, business-specific models (e.g., blocking competitor mentions)

- A rules engine that combines all model outputs and issues the appropriate treatments

Two Hat and Azure kinda had this, but they didn't support custom models or rules engine.

While I love the idea of redacting/auto-correcting media, e-commerce / social media companies are structurally setup against this. They'd rather stick with the status quo of rejection, than using nano-banana to remove non-compliant features (like pii) from the images.

Once, I had to anonymize student data, so we could have a prod copy on staging. So maybe there is a use-case there...
