Personal data never reaches the model.
Names, emails and numbers become placeholders the instant they arrive. The AI reasons over [CLIENT_1], and the real values are reattached only inside the one tool that sends.
Secure AI EU-hosted
It does the work: drafts, schedules, chases what you’re owed. And it does it on client matters you’d never put in ordinary AI. Your data is redacted before the model, every send is held for your approval, and it all runs in Europe.

Three things happen to every command. None of them is a setting you remember to switch on. It’s how the thing is built.
Names, emails and numbers become placeholders the instant they arrive. The AI reasons over [CLIENT_1], and the real values are reattached only inside the one tool that sends.
For sending, deleting, or sharing externally, you decide which actions just happen and which pause for approval. The default is to hold, and the assistant can’t act around the rule.
A tamper-evident, hash-chained log you can hand a client or a regulator.
Watch one request make the round trip: sent in your words, redacted before the model, processed as tokens, reattached only inside the draft you approve.
Draft a note to Henderson Acquisition confirming we’ll close the €4.2m deal by Friday.
No new app to open. Message euroclaw where your work already happens. It reads the thread, does the work across your apps, and holds anything client-facing for your yes.
You ask · it works across Outlook, Teams and your files · it holds anything client-facing for your yes.
The same governed engine in every form: redaction before the model, your approval before every send, a tamper-evident record after. Start by running it yourself, and let us host it when you’re ready.
Run the whole agent on your own machine: a single binary, nothing leaves the device. The fastest way to start, and as private as it gets.
Deploy into your own cloud or servers. Client data never leaves your perimeter; you operate it. Open-source, so you can inspect every line and run it air-gapped.
We run it for you: EU-resident, isolated, with redaction, the approval gate, and the audit trail on by default. No infrastructure to manage.
Open-source at the core, so the guarantees hold wherever it runs, and you can prove it.
The question is whether you can point it at a named client matter. Its protections are real, but they’re opt-in, Enterprise-gated, and US-only. You don’t have an IT team to configure them.
Client data redacted before the model
No published redaction layer. Anthropic documents none for Cowork, so client data reaches the model in full.
SourceYes
A record you can hand an auditor
Hosted and processed in the EU
EU AI Act compliant
Model-level only. Anthropic signed the GPAI Code; those rules bind the model (in force since Aug 2025), not how you deploy it.
SourceBy design, for your deployment
Works without an IT team
No. Zero-data-retention is Enterprise-only, needs Anthropic’s sign-off, and doesn’t cover Cowork at all.
SourceYes
Comparison as of June 2026, from Anthropic’s own docs and public sources. Cowork is excluded from the Compliance API and zero-data-retention, and runs US-inference only. Each row links its source; product details may change.
