Kiren by F-Secure

Online scams have never been more convincing. 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.

CHECK BEFORE YOU ACT
• Link Checker: Confirm whether a link is safe before you open it. Shopping sites get a trust rating, useful before buying from an unfamiliar store.
• Message Checker: Paste in a suspicious text and find out in seconds whether it shows signs of a scam.
• Breach Check: See whether an email address has appeared in a known data breach.
• Your Apps: Analyse your apps to see exactly what they can access, so you can revoke permissions that put your privacy at risk.
• Quick Access to find, lock or wipe your lost device.

PROTECTION THAT RUNS IN THE BACKGROUND (Kiren Plus)
• Device scan: Antivirus makes it easy to identify, clean & remove viruses from your Android device. It checks new downloads and apps the moment they arrive, runs a daily scan, and removes threats.
• Personal data monitoring: Watches your email addresses, phone numbers, payment cards, and identity documents around the clock. 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. Bank and shop with confidence with Safari Browser. Browsing Protection verifies that banking sites are real and rates online stores before you buy.
• Message Protection: Detects scam messages from unknown senders in SMS and WhatsApp, and gathers the harmful ones in one place. Conversations with your contacts are never analyzed.
• Breach Report: Get timely alerts whenever a company, app or service you use has a data breach along with info about how to best secure your data.

KEEP YOUR DEVICE IN GOOD SHAPE
• Device Health checks that a screen lock is set, the first line of defense if your phone is lost or stolen.
• Your Apps shows what each installed app can access, such as the camera, microphone, location, and contacts. An app with more access than it needs stands out.
• Recent News keeps you informed about data breaches and current scams.
