Launched in the mid-2010s, they quickly gained popularity, amassing over 100 million downloads on Google Play thanks to their robust free offering. They aim to shield users from mobile threats, scan for malware, block phishing links, and alert users to potential scams, even within messaging apps. Over the years, PSafe has enriched dfndr security with extra features such as phone location tracking for lost devices, an app lock to protect privacy, and data breach monitoring to help users stay ahead of identity thieves. Users of dfndr security praise its ease of use, comprehensive toolkit, and free basic protection. The app’s interface is straightforward, making complex tasks like clearing junk files or securing the device accessible with a single tap. They also enjoy a strong reputation in the antivirus industry’s tests, having achieved perfect scores in some AV-TEST evaluations.
