As answered by people managing Learn JavaScript and PromptLock.io.
PromptLock.io's answer:
PromptLock is the only AI firewall that understands compliance context. It doesn't just detect sensitive data—it automatically applies the right redaction policy (HIPAA, GDPR, or PCI) based on the type of data detected, all in a single API call. No manual rule configuration required.

PromptLock.io's answer:
PromptLock is built for startups and SMEs, not enterprises. You get production-ready security in minutes with straightforward pricing ($49-199/month), a generous free tier, and no-code integrations for n8n, Flowise, Bubble, and Retool. No sales calls, no enterprise contracts, no DevOps required.
PromptLock.io's answer:
PromptLock was born from seeing the same problem repeatedly: AI apps leaking sensitive data to LLMs or getting jailbroken by prompt injection attacks. Existing solutions were either enterprise-only with lengthy sales cycles, or open-source tools requiring significant DevOps overhead. We built PromptLock to give smaller teams the same protection with a simple API they can integrate in an afternoon.
PromptLock.io's answer:
PromptLock uses a fine-tuned DeBERTa model for prompt injection detection, spaCy-based NER for PII/PHI identification, and custom compliance logic for context-aware redaction. The API runs on a Python backend with Redis for rate limiting and GPU-accelerated inference for fast response times.
