Whistler
What Whistler is
Whistler is a web platform for organisations to receive confidential whistleblowing reports and manage the cases that follow. Reporters can submit through a URL on a computer, tablet, or smartphone without creating accounts or downloading software. The reporting page has no trackers, analytics, or embedded third-party content, and its form is available in 12 languages. Reports may include documents, images, and audio files; attachments are encrypted with the report and limited to 5 MB per file. Organisations can create cases, connect reports, add internal notes, and maintain an audit trail of actions. Whistler says it requires no integration with existing systems. Its security information specifies HTTPS with TLS 1.2 or higher for data in transit, AES-256 for stored data, and a one-time decryption key for each report that staff cannot access. Plans start at $19/month, and a 30-day trial is available; there is no free plan. The terms say user-created content cannot currently be exported.
