Pangea is the "Twilio for Security" — a set of composable security APIs that developers embed directly into AI applications. It provides audit logging, data redaction, embargo compliance, IP reputation, and domain intelligence as simple API calls. For AI apps, Pangea's Redact API strips PII from prompts, its AI Guard detects prompt injections, and its Audit API creates tamper-proof logs of all AI interactions.
