What we are building

One API, every check

Point your agent at the EU Mode API. Every request, tool result, reply and agent action will then pass the checks for each law, side by side, in the EU. Each check can allow, block, mask, escalate, or just log. Start in shadow mode: it records what it would have blocked and blocks nothing.

HaloGuard EULive

The first part of EU Mode. Built on Google's Gemma, it works in all 24 official languages of the European Union and runs in the EU.

It can miss output it should block, and it can block output that is fine.

Looks for personal data in what you send and masks it before it reaches the model. The answer carries a map back to the originals; putting them back is your step. Results on six public benchmarks are at astroware.ai/benchmarks.

Until our data processing agreement is signed with your company, send no personal data to the API.

Dangerous action checks for AI agents: blocks a dangerous action or flags it for a person to approve.

A technical control you can show your customers and auditors.

EU Mode is Astroware's name for these controls. It is not an official EU product, and using it does not by itself meet any law's requirements. HaloGuard EU is a technical control, not legal advice or a compliance guarantee. Items marked Planned or In development are not available yet, and we give no dates for them here.
