About Us
Why Whistler exists
Whistler was first developed in 2015 to address a fundamental challenge: how to make it safe for people to report wrongdoing, while giving organisations the ability to respond with confidence and discretion.
Traditional reporting channels — hotlines, email, even suggestion boxes — often fail to protect the identity of the person speaking up. Fear of retaliation remains the single biggest barrier to reporting. Whistler was designed to remove that barrier entirely.
Reports submitted through Whistler are encrypted and accessible only to the people your organisation has authorised. No accounts, no tracking, no voice recordings. Just a secure, anonymous way to do the right thing.
What makes Whistler different
Many reporting tools treat security as an afterthought. Whistler is built around it. Every report is encrypted at the field level, and only your organisation's authorised personnel — with the correct passkey — can decrypt them. Not even Whistler staff can read your reports.
At the same time, we've kept the experience simple. Whistleblowers don't need an account, a download, or any technical knowledge. Organisations can be up and running within a day, with no integration work required.
Built for organisations of all sizes
Whistler is used by corporates, non-profits, government agencies, schools, and universities. Whether you have ten employees or ten thousand, the platform scales to fit your needs with plans designed for every size of organisation.
The reporting form is available in 12 languages, making Whistler a practical choice for organisations with a global or multilingual workforce.
Supporting your compliance obligations
Many jurisdictions now require organisations to provide secure, confidential reporting channels for employees. Whistler helps you meet these obligations with a platform that is designed for privacy and built to protect the people who use it.
Our Privacy Policy is transparent about exactly what data we collect, how we protect it, and the rights you and your employees have over that data.
