Use any LLM without sending private data.
Redact sensitive data before prompts leave your organization — then route the clean request to the best model.
Frontier models for your teams. Private data stays behind your boundary.
Customer [NAME_1] (SSN [SSN_1], [EMAIL_1], [PHONE_1]) is disputing a $1,240 charge on account [ACCT_1]. Summarize the issue and suggest next steps.
Your teams want AI. Your data can't be the price of using it.
It's not capability — it's exposure. Records get pasted into chat tools, documents into copilots, personal details into assistants. None of it malicious; all of it leaves your boundary.
Enterprises solve this with private deployments and per-vendor agreements. Most teams can't — so it becomes productivity or privacy. Sluice removes the trade-off.
Stop sensitive data before it reaches the model provider.
Sluice sits between your apps and the LLMs they call. Sensitive values become safe placeholders before a request leaves — then rehydrate inside your environment.
The model sees the shape of your request — never the private parts.
Connect once. Every prompt gets the same treatment.
Connect
Point your apps, chat tools, and copilots at Sluice. Existing integrations keep working.
Detect & redact
Strip PII, PHI, and sensitive business data into safe placeholders before the prompt leaves.
Route
The clean request goes to the best model by cost, speed, or policy — any provider, no raw data.
Return
The response returns through Sluice, where placeholders rehydrate inside your environment.
Built for the teams accountable for the data.
PII & PHI redaction
Rules plus lightweight ML catch personal and health data before it leaves.
LLM provider routing
Route by cost, latency, or policy — across providers, one endpoint.
Policy-based controls
Rules per team, app, or use case: strictness, allow-lists, guardrails.
Audit logs & visibility
What was redacted, where it went, which policies applied — retention you control.
Prompt & response inspection
Compare sanitized prompt and rehydrated response to verify what left.
Optional local filtering
Where supported, detect closer to the source to minimize raw data earlier.
Placeholder mapping & rehydration
Reversible mappings keep reasoning intact; real values restore only inside.
Multi-provider support
Add, swap, or fail over between providers without rewriting your apps.
Developer-friendly API
One endpoint instead of each provider — redaction and routing in the path.
Admin dashboard
A control surface for security and compliance to manage policy and usage.
One privacy layer, many workflows.
Summarize and triage tickets without exposing customer records.
Cut PHI exposure in AI workflows that would otherwise send it to a third party.
Analyze claims and documents with account and personal data redacted first.
Answer employee questions without leaking HR or customer data to external models.
Ship AI features without sending raw user data to model vendors.
Use LLMs across client data with policy-enforced privacy per engagement.
A practical privacy layer — without giving up the best models.
| Direct public LLM use | Enterprise agreements | Self-hosted models | Sluice | |
|---|---|---|---|---|
| Setup effort | Lowest | High — legal & procurement | High — infra & ops | Low — route through one gateway |
| Private data exposure | High | Reduced, per contract | Lowest | Reduced — redacted before it leaves |
| Access to frontier models | Yes | Yes, per vendor | Often lags | Yes — across providers |
| Cost profile | Pay-per-use | Expensive, vendor-specific | High to operate | A gateway over existing usage |
| Vendor lock-in | Per tool | Strong | N/A | Low — multi-provider |
| Privacy control | Minimal | Contractual | Full, but you own it all | Policy you enforce in the path |
Easy but exposed. Strong but expensive. Controlled but hard to run. Sluice puts a practical privacy layer in front of the best models — without a separate deal per vendor.
A strong protection layer. Not a silver bullet.
The safest data to send is none. Sluice removes it before the request leaves.
Redaction, allow-lists, and guardrails are rules you define and apply consistently.
One layer beside your own access controls and policies — not a replacement.
See what was redacted, where it went, and what was retained.
What we don't claim
Sluice helps reduce the chance sensitive data reaches a third-party model. No automated system catches everything, and it doesn't make you HIPAA compliant, SOC 2 certified, or legally compliant on its own.
It's a real, enforceable privacy control — we'd rather say that plainly than oversell it.
Drop-in API compatibility for AI apps.
Your apps call sluice instead of each provider. It redacts, applies policy, logs what you choose, picks a provider, and returns the response — all in the path.
One endpoint in. Redact, route, return — apps don't change when routing does.
Stop private data before it leaves.
Give your teams access to powerful AI without giving every model provider your sensitive data.
We'll only email you about early access.
