We set out to solve one problem, and the answer was a lock.
We build AI for organisations that can't gamble: healthcare, government, logistics. The team wants to. The DPO hesitates. The project waits.
Nobody blocked it. No one could prove what happened to the data. So we built the proof, then a product.
The Netherlands sits below sea level and figured something out: you don't fight the water, you control it. A lock holds back the sea and lets the ship through. For centuries. Every day. Ledger included.
Every request enters a sealed chamber: inspected, routed under your residency policy, handed to a model. A gate between the frontier and your jurisdiction, never a hole. Every passage logged.
Frontier models such as Claude, Gemini, Grok and Mistral, routed only where policy allows and pseudonymized so no name or number leaks.
Every call is sealed in a hash-chained ledger you can export and re-verify offline.
You declare where data may go; we enforce it and hard-block anything that doesn't qualify.
Sluis exists so regulated teams can use frontier AI. The default is the strictest setting, EU-only, until you decide otherwise. Wherever you answer to a regulator, the lock works the same.
Where one careless egress is a breach notification, and “we think it stayed inside” convinces no one.
Sluis is a product of SevenLab (7Lab B.V.), based in Amsterdam. The managed cloud runs on EU infrastructure, because where a vendor sits decides which laws reach your data, and which government can compel it.
We surface what other gateways hide: not just where a model runs, but who owns it, so every deployment wears its legal exposure on the label, CLOUD Act included.
Eighteen years of software and AI at SevenLab, for hundreds of public and corporate clients. Sluis is the product we wanted ourselves.
Procurement, a security questionnaire, a signed DPA, a self-hosted Sluis Edge gateway, or a plain question: whatever your compliance team needs to say yes. A human reads it.
