AI Testing of Mobile Apps: How NowSecure AI-Navigator Automates Authenticated DAST

Mobile app security teams face mounting pressure to test faster and cover more ground as authentication and mobile apps themselves grow more complex. At the same time, AI accelerates mobile app development and the adoption of mobile AI features, driving higher app volume, more frequent releases and increasingly complex supply chains. As a result, security teams look to AI-assisted testing to scale and uncover the vulnerabilities, data leaks and third-party risks that emerge at runtime.

Industry data reflects this shift. According to Sensor Tower’s State of Mobile 2026 report, downloads of Generative AI apps more than doubled in 2025 to reach 3.8 billion, underscoring how rapidly AI-enabled mobile experiences are proliferating across the ecosystem. 

Dynamic testing reveals how a mobile app behaves at runtime and provides the only practical way to uncover many of the most dangerous vulnerabilities, data leaks and supply-chain risks. These issues typically surface only after authentication, when real users interact with sensitive data, privileged workflows, third-party SDKs and backend APIs that static testing cannot meaningfully assess.

Despite its importance, most organizations struggle to perform authenticated dynamic testing consistently. Authentication introduces one of the biggest automation barriers. Dynamic user interfaces, changing business logic, access-level differences and constantly rotated credentials create friction that slows mobile application security testing and undermines effective mobile app risk management. 

“Mobile apps are the front door to enterprise and consumer data, but traditional security testing has struggled to effectively test what happens after login — where the most critical vulnerabilities often hide,” says NowSecure CTO David Weinstein. “AI-Navigator combines AI automation with our proven real-device dynamic testing platform to deliver complete coverage from login to logout.”

To eliminate this barrier, NowSecure enhanced its NowSecure Platform mobile application security testing solution with AI-Navigator. AI-Navigator is a groundbreaking AI-powered testing capability that automatically interprets and navigates mobile app user interfaces, beginning with app login workflows, to enable fast, consistent, resilient, scriptless authenticated testing.

Why Authenticated Testing Needs a Smarter Approach

Traditional methods for authenticated dynamic application security testing (DAST) rely heavily on scripted interactions, which frequently break as apps evolve. Even small UI adjustments, new login logic or updated user privileges force mobile app security teams back into time-consuming maintenance.

As a result, many organizations fall back on static testing adapted from web application security tools, checking a compliance box without testing how the mobile app actually behaves at runtime. This leaves authenticated dynamic testing inconsistent or applied only to the highest impact mobile apps, despite the fact that most critical security, privacy, supply-chain and shadow AI risks remain hidden behind the login screen.

AI Navigator Simplifies and Speeds Authenticated Testing

AI-Navigator removes the complexity of manual scripting by applying AI testing techniques in real time to understand login screens, recognize required interactions and guide the app into an authenticated state automatically. This replaces brittle scripts and reduces authenticated testing setup and execution time by over 90%, turning a process that once took days into minutes and allowing teams to consistently reach deeper, post-login areas of their mobile apps.

By adapting to changing interfaces and business logic, AI-Navigator maintains reliable navigation across app updates, ensuring continuous coverage even as development teams move quickly. With authentication handled automatically, AppSec teams can spend more time testing critical functionality and less time troubleshooting automation.

How AI Navigator Improves Mobile App Security Workflows

1. Faster Setup and Immediate Use

AI-Navigator eliminates manual scripting, allowing security analysts and developers to begin authenticated testing quickly and consistently.

2. Reliable Navigation Across App Updates

Because AI adapts to UI and logic changes, authenticated testing remains stable across new versions and releases to ensure scans reliably make it past the login screen. Among the 91% of apps eligible to use AI-Navigator for authentication, early adoption results show teams achieving a 100% authentication success rate for automated dynamic testing. 

3. Expanded Testing Coverage

Once authenticated, teams can test up to 95% of the mobile app that sits behind authentication, including deeper workflows, privileged features, sensitive data transactions, critical APIs, third-party SDKs and regulated data that are inaccessible in unauthenticated scans.

4. Greater Efficiency for AppSec Teams

Automation of the login step frees analysts from repetitive setup work, enabling more frequent, comprehensive testing without additional overhead.

5. Stronger Risk Reduction

Authenticated testing exposes vulnerabilities, data privacy exposures and logic flaws that traditional unauthenticated scans often miss.

Building Confidence with a Privacy-First Design

AI-Navigator applies AI in a secure and transparent way, with clear boundaries around how data is handled. All authentication handling, credentials and testing data remain entirely within the NowSecure Platform and never interact with external or third-party AI models.

To guide navigation, the AI uses only non-sensitive, anonymized visual and structural elements such as screen layout and UI context in real-time. Customer applications, credentials and testing data are not stored, retained in memory, or used to train AI models, ensuring organizations maintain full control of their data while preserving auditability for security, privacy and compliance requirements.

Powering More Scalable AppSec Programs

As mobile development accelerates, AppSec teams must keep pace without increasing costs or sacrificing depth of coverage. AI-Navigator helps scale testing by reducing the operational burden of authenticated setup and increasing the number of apps and workflows teams can assess. Organizations can more easily establish repeatable, consistent testing processes that fit into modern DevSecOps pipelines and mobile release cadences.

Available Now in NowSecure Platform

AI-Navigator is now available in the NowSecure Platform, enabling customers to streamline authenticated testing workflows and consistently test deeper, post-login areas of their mobile applications as part of their ongoing security programs.

Setting a New Standard for Mobile Security Testing

As mobile application development  cycles accelerate, and mobile experiences grow more sophisticated, traditional testing methods can no longer keep up. Continuous testing that regularly tests the entire app is critical. Leveraging AI-based authenticated testing enables teams to meet these demands reliably without ongoing manual intervention. 

With AI-Navigator, NowSecure redefines how teams perform authenticated mobile DAST — making it faster, smarter and more accessible than ever before. Want to see AI-Navigator in action?
