Comparison
Network DLP vs NoeticGuard
Network DLP watches packets. Employee LLM chats are TLS to OpenAI/Anthropic — interception is hard. NoeticGuard masks in the page before egress.

Feature comparison
Side-by-side for teams evaluating LLM egress controls — not a full enterprise DLP bake-off.
| Capability | NoeticGuard | Network DLP |
|---|---|---|
| Sees ChatGPT HTTPS body | Yes — page-context masking | Often no (TLS / pinned apps) |
| Proxy / MITM required | No | Usually yes for HTTPS inspection |
| Developer LLM API traffic | SDK in your backend | Depends on egress gateway coverage |
| Raw prompts to security vendor | Never for masking | Often yes (CASB / cloud DLP) |
Why client-side beats cloud DLP for LLM prompts
NoeticGuard is a local-first DevSecOps toolkit: @noeticguard/core masks PII with deterministic tokens in your app, backend, CLI, or Chrome extension before text reaches LLM APIs. The NoeticGuard API syncs policy and quota — it does not receive raw prompts to mask.
- Browser LLM UIs are designed for end-to-end TLS; many DLP agents never decrypt the prompt.
- Client-side masking runs at the source — the same place the employee types.
- NoeticGuard API only syncs policy/quota; it is not another cloud that stores customer chat text for scrubbing.
