- Public materials describe a customizable report page, automated case management, anonymous two-way communication with reporters, file upload, and an ombudsperson option.
- Two published packages: Essential at EUR 59/month (English and German) and Pro at EUR 99/month (five languages: English, German, French, Spanish, Chinese), both priced regardless of employee count.
- A 10-day free trial is advertised.
- Security messaging states end-to-end encryption and hosting on ISO 27001 certified servers in Germany; the certification is the hosting provider’s, not a whistly vendor certification, and the provider is not named.
- Customer-count claims are inconsistent across the site: the LkSG page says 100+ companies, the about page says over 200 businesses, and the vendor blog says 500+ European companies.
- No public API documentation, sub-processor list, DPA download, or article-level Directive/HinSchG mapping was found on pages reviewed; the site renders via JavaScript and exposes little static HTML.
