Scammers are getting smarter.
Kiren is getting ahead of them.

Kiren is a mobile-first scam protection app that keeps you safe from phishing, fake messages, unsafe links, and online fraud before they reach you. And we're looking for a small group of people to try it first.

As an F‑Secure Mobile Security user, you're already someone who takes protection seriously. That's exactly why we want you in.
