We want to encourage employees to adopt better cybersecurity practices in a way that's actually effective, and entertaining enough that the training doesn't feel like work. Think Duolingo, but for cybersecurity. We created a platform to roll out a cybersecurity awareness program quickly and easily by sending short conversations of just 3-4 minutes. The platform also simulates phishing attacks to prepare employees to face hackers in a safe environment. Created in 2020, Riot has raised $45m with leading investors (Y Combinator, Left Lane, Base10, Funders Club and Frst Capital) and is now protecting more than 2 millions employees in over 2,000 companies (including Intercom, Deel, and Deezer) all over the world. Cybersecurity impacts everyone, every day, and is now the number one risk to any organization, from small businesses to big firms. And yet, in most companies the cybersecurity culture is non-existent. Hackers know this, and they're taking advantage by targeting the weakest link: employees. We're on a mission to fix that for good.

We make the world's networks safer by providing a rich, unique data source for network traffic analysis.
