Recipients click ‘Open’ on the notification delivered to their inbox. They’ll answer your challenge in our browser app, or, if they're trusted, they’ll open and read right away.

A digital world
In a digital age, it's more important than ever to prioritise online security. Email is a popular mode of communication for personal and professional purposes, but many email providers may not offer adequate protection against cyber threats.
Open to threat
