With more than two billion users, WhatsApp is very powefull when it comes to apps in general. With this level of success comes increased exposure to those who would do WhatsApp users harm. But of course, no app is immune to security vulnerabilities; they are a fact of technological life.

WhatsApp has recently fixed critical and high-severity vulnerabilities affecting WhatsApp for Android, WhatsApp Business for Android, WhatsApp for iOS, and WhatsApp Business for iOS. The Indian Computer Emergency Response Team (CERT-In) has issued a high-severity security warning for WhatsApp users in India. It has again confirmed that businesses need a mobile security solution to secure their devices.
