A store that looks real but never ships the order. A text that looks like it comes from your bank. A video of someone who never said those words. These are not aimed only at the careless. They are built to catch anyone, on an ordinary day, in the middle of an ordinary purchase or message. Kiren is a premium digital safety app from F-Secure, made for exactly these moments. It helps you tell what is real from what is fake, and it keeps watch over your identity and your phone. F-SECURE MOBILE SECURITY IS NOW KIREN Kiren is the next version of F-Secure Mobile Security, built by the same team and completely redesigned.

If any of them appear in a new breach, you get an alert with full details and step-by-step guidance on what to do. • Scam Scanner: Upload a screenshot of a listing, an offer, or a photo and Kiren's AI checks it for scam tactics and deepfake manipulation. • Browsing Protection: Prevent cyber-criminals from redirecting you to malicious websites while using Chrome browser.
