HOVIGuard is a B2B SaaS — an AI security and governance gateway giving organisations access to 100+ leading AI models with centrally configurable security and privacy filters (MultiLayer Data Shield), an audit trail and tenant isolation.
HOVIGuard is operated by Ing. Dipl.-Ing. (FH) Karl J. Pilz, sole proprietorship based in Anif-Niederalm near Salzburg, Austria (VAT-ID ATU 66845907). Details are listed in the legal notice.
Sagmüllerweg 8, 5081 Anif-Niederalm, Salzburg, Austria. The competent supervisory authority is the Austrian Data Protection Authority (DSB) in Vienna.
Application data in Germany (Hetzner Falkenstein), AI requests via EU-bound gateways (AWS Frankfurt and France) plus EU direct routes. Details and sub-processors are in the Data Processing Agreement and on the EU Data Processing page.
User interface currently in German and English. AI models typically support 100+ languages; the safety layer (Qwen3Guard-Gen-4B) covers 119 languages.
HOVIGuard is not a model but a gateway. We route requests through curated EU-hosted providers, filter PII and disallowed content before forwarding to models, log every interaction for audit purposes, and let admins control model and feature access per team.
