Small businesses face the same network threats as enterprises but can't afford $100K/year NDR tools. We built ThreatLedger to change that.

ThreatLedger is a cloud-native Network Detection and Response dashboard that turns raw security logs into actionable threat intelligence using AI.

**Live demo:** [https://threatledger-app.vercel.app](https://threatledger-app.vercel.app)

Aurora gave us a production-ready database from day one. We enabled pgvector for future semantic search across 21,742 IP reputation records. The Prisma + Aurora combination gave us type-safe queries with zero configuration overhead.

Getting Prisma 7 working with Aurora on Vercel's serverless environment required configuring PrismaPg adapter with connection pooling and handling SSL correctly.

Semantic similarity search using pgvector, MITRE ATT&CK mapping, and real-time log streaming.
