In this episode of Upwardly Mobile, we dive deep into the critical, yet often underestimated, world of mobile app security. Drawing on recent research, we uncover a staggering misalignment between perception and reality, highlighting why organizations are facing an average of nine mobile app security incidents per year, with an average financial toll reaching $6.99 million in 2025.

While 93% of organizations believe their mobile app protections are sufficient, a substantial 62% have experienced at least one security incident in the past year. The repercussions extend beyond financial losses, including application downtime, sensitive data leaks, erosion of consumer trust, and a diminished user experience.

We explore why traditional security measures, particularly code obfuscation, are no longer enough. Obfuscation, while deterring casual attackers, is ultimately a deterrent, not a preventative measure, offering minimal protection against runtime threats, dynamic analysis, and AI-assisted reverse engineering.

The real target for modern attackers is increasingly Application Programming Interfaces (APIs). Mobile apps serve as entry points to exploit backend APIs for credential stuffing, data scraping, and business logic abuse, none of which static defenses can prevent. The weaponization of Artificial Intelligence (AI) further escalates these threats, enabling automated botnets, adaptive malware, and accelerated vulnerability discovery.

The solution? A crucial shift towards a dynamic, runtime-centric security model rooted in Zero Trust principles. This approach demands continuous monitoring and verification, moving beyond static, pre-deployment checks to protect apps during execution.
Key elements of this essential dynamic security strategy include:
• Mobile Runtime Application Self-Protection (RASP): Acting as the app’s internal bodyguard, RASP detects and responds to runtime threats like debuggers, tampering, root/jailbreak, and hooking frameworks, offering real-time protection and contextual awareness.
• App Attestation & API Request Validation: This is a standout feature, ensuring that only requests truly originating from your official, unmodified mobile app, running on a non-compromised device, are allowed to access your backend APIs. This effectively blocks bots, scripts, tampered apps, and mitigates API abuse.
• Runtime Secrets Protection: This critical measure removes sensitive secrets (like API keys) from the app's code entirely. Instead, secrets are delivered securely at runtime, just-in-time, and only to attested apps, preventing extraction through reverse engineering.
• Dynamic Channel Protection (Dynamic Pinning): Unlike brittle static certificate pinning, dynamic pinning allows for secure, over-the-air updates of certificate pins, ensuring continuous protection against Man-in-the-Middle (MitM) attacks without requiring app store updates.
We also differentiate between leading mobile app security solutions:
• Guardsquare, with products like DexGuard and iXGuard, excels in client-side mobile app protection, focusing on code obfuscation, hardening, and RASP to make the app's code incredibly difficult to compromise on the device.
• Approov emphasizes remote mobile app attestation, performing deep, continuous inspection of the mobile app and device in the cloud. This server-side decision-making makes it significantly harder for attackers to bypass the attestation process, ensuring only genuine apps access your APIs. Approov's positive security model effectively "locks down" backend APIs.
Ideally, a comprehensive mobile app security strategy leverages both types of solutions: Guardsquare for strong in-app protection, and Approov for critical API integrity and abuse prevention. This multi-layered approach, combining static and dynamic defenses, is no longer optional but a fundamental requirement for achieving adequate resilience against modern mobile threats.
