Why Mobile App Security Keeps Failing (And What It Takes to Fix It)

Mobile applications have become the primary interface between organizations and their customers. Across every major industry, the app is where the relationship lives. Unfortunately, that’s also where attackers focus their efforts.

Ninety-two percent of organizations reported increasing mobile app threat levels over the past two years. Three out of four experienced a security incident, with nearly two-thirds losing customers as a direct result. These stats reflect a structural gap between how mobile apps are built and how they are protected.

Our new Guide to Mobile Application Security examines that gap in detail, along with what it takes to close it.

The problem with how security gets prioritized today

Time-to-market pressure is the most commonly cited barrier to stronger mobile application protection. The pressure on development teams is real. Release cycles have accelerated to match customer demand, and anything that slows delivery tends to get deprioritized. Security is no exception.

As a result, testing happens late, vulnerabilities are discovered close to launch, and teams are forced to choose between delaying release or shipping code they know is flawed. More than half of organizations admit they have made the second choice.

That tradeoff only makes sense if you treat security as separate from delivery. When security is embedded into the development lifecycle (meaning that it is running continuously as code is written and updated), it stops being a bottleneck and becomes a feedback loop. Teams find security issues earlier, when they are cheaper and faster to resolve.

Mobile app threats are becoming more sophisticated

The guide examines threat patterns across six industries: financial services, retail, healthcare, telecommunications, media and entertainment, and mobile gaming. The specific attack types vary, but the underlying dynamic is consistent. Expanding mobile footprints attract more sophisticated and more frequent attacks.

For example, in financial services, account takeover fraud has surged — 71% of financial fraud losses now trace back to compromised credentials. In healthcare, the industry saw a 224% increase in mobile attacks last year, and insecure mobile apps are now the top cybersecurity concern in the sector. In retail, loyalty and rewards programs account for nearly one-third of all fraud attempts against online merchants.

Each vertical carries distinct compliance obligations as well. The guide covers the regulatory landscape across PCI SSC, HIPAA, DORA, GDPR, and regional frameworks, as well as how to remain compliant while keeping apps secure.

Protection requires more than testing alone

Automated mobile app security testing during development addresses one part of the problem. It reduces the volume of vulnerabilities that reach production and shifts the cost of remediation to the earliest possible point in the software development lifecycle (SDLC). But it does not protect an app once it is deployed.

Post-release threats require a different set of controls. Code hardening, including techniques such as encryption and obfuscation, makes it significantly harder for attackers to reverse engineer application logic, extract credentials, or modify behavior. Runtime application self-protection (RASP) gives the app the ability to detect and respond to threats as they occur — catching tampering, instrumentation, and manipulation in real time.

Threat monitoring then closes the visibility gap. Without insight into how deployed apps are being targeted, security teams are working from assumptions rather than real-world data. Real-time telemetry allows teams to see which tools and techniques attackers are using, distinguish compromised users from deliberate bad actors, and adapt protections based on what is actually happening in production.

The API layer is where many defenses fail

Client-side protections, however strong, cannot address every threat vector. Attackers frequently bypass the app entirely and communicate directly with backend APIs using bots, emulators, or modified clients. Those requests can appear legitimate to systems that have no way to verify the integrity of the source.

Mobile API security closes that gap. By verifying that every request originates from a genuine, unmodified app running on a secure device, app attestation prevents non-legitimate clients from reaching backend resources. More than eight in ten organizations say their exposure to mobile API and backend abuse is increasing — yet fewer than half monitor their API activity.

A model built for how threats actually work

The guide makes the case for treating mobile app security as a continuous system rather than a collection of point controls. Testing in development, in-app hardening, runtime visibility, and API enforcement each address a distinct layer of exposure. When those layers are integrated, weaknesses in one area can be addressed by another, and insights from production inform how protections evolve over time.

That architecture matters more as AI-generated code becomes the norm. Eighty-one percent of developers say AI-generated code introduces new vulnerabilities. The tools accelerating development are also expanding attack surfaces. Security that integrates into the pipeline — rather than sitting outside it — is the only model that keeps pace.
