Mobile App Security Is More Important Than Ever — Here’s Why

Mobile apps are no longer just lightweight clients running on phones. They are connected platforms tied to identities, payments, sessions, APIs, cloud services, healthcare, retail, gaming, and business-critical workflows. In this special episode of the Shared Security Podcast, Tom Eston talks with Joel Destefano, Senior Product Manager at Guardsquare, about the modern mobile application threat landscape and what organizations need to understand about protecting mobile apps today. We cover runtime manipulation, API abuse, account takeover, fake apps, overlays, malware-assisted fraud, reverse engineering, iOS vs Android risk, AI-assisted attacks, and why backend-only security is not enough.
