BeVigil scans all the apps installed on a user’s phone and rates them as dangerous, risky, or safe. Running as a web application for the past one year, BeVigil has already scanned over a million apps and rated them. The tool also alerts software companies and app developers about vulnerabilities found through the app, and helps users and developers win bug bounty contests from various software companies by giving them access to the code of apps running on their phone and reporting bugs.
