Two approaches to LLM privacy: TEE-based encryption vs. pattern matching with EU hosting. Which fits better?
View ComparisonOpaquePrompts uses Trusted Execution Environments (TEE) for maximum security - but English only, not configurable, Enterprise pricing. PrivacyProxy is more affordable, supports 27 EU languages, and is ready to use immediately.
OpaquePrompts encrypts PII in a TEE - nobody (not even Opaque) sees the data. Maximum security, but: English only, not configurable, Enterprise pricing. PrivacyProxy uses proven pattern matching (Presidio + spaCy + GLiNER) - fast, configurable, multilingual.

opaque.coGDPR-compliant LLM proxy with pattern matching (420+ patterns). Hosted in Germany, ready to use immediately, SMB-friendly pricing.
