Mobile App Development Frameworks - a security guide 🍼

This week I finally published a long article on the mobile development security guide. If you choose a technology for your brand new mobile application, it will help understand what are the security concerns for each of the technology starting with native Kotlin/Swift development through React-Native and Kotlin to Hybrid HTML-based apps. In the end, you will find a comparison table with the severity of common mobile threats which will guide your technology choice.
