⚡️ Semantic Sanitization & Hardware TEE Enclaves
Before any proprietary codebase snippet reaches external LLMs, the GitLab AI Gateway passes it through a deterministic local entropy filter. Internal IP addresses, API secrets, and sensitive identifiers are stripped and replaced with synthetic placeholders.
Payloads traverse an encrypted mTLS 1.3 tunnel with sub-14 ms overhead. Upstream inference executes inside Confidential Computing (TEE) enclaves, ensuring session RAM is cryptographically wiped immediately following generation.

⚖️ Corporate Code Security Paradigm Shift
Было: Sending raw source files to third-party cloud APIs without sanitization ➔ Стало: Local secret masking and mTLS 1.3 tunneling into encrypted hardware enclaves
Было: Risk of private algorithms leaking into public LLM training corpuses ➔ Стало: Legally binding Zero-Retention SLA with cryptographic ephemeral memory destruction
