NowSecure ADA MASA (Mobile Application Security Assessment) is an independent security review service for Android developers to validate their mobile app security and privacy for Google Play. It allows developers to demonstrate adherence to security best practices and increase app downloads by applying an independent security review badge to their app's data safety information in the Google Play store. NowSecure ADA MASA is based on the Open Web Application Security Project (OWASP) Mobile Application Security Verification Standard (MASVS) and uses the OWASP Mobile Security Testing Guide (MASTG) to evaluate Android apps against MASVS L1 requirements.
