Continuous Mobile Risk Governance for Modern Banking
Mobile banking apps evolve far faster than annual audits can track, yet new regulatory standards demand a real-time Mobile App BOM and continuous runtime validation. NowSecure automates dynamic testing inside your release pipeline—ensuring every build shipped to production is audited, compliant, and defensible.
The hidden risk surface of mobile banking applications
New regulatory mandates require a continuously maintained inventory of all third-party mobile code. Financial institutions are fully accountable for every component shipped to production, including software your internal engineers never wrote.
Applications will typically ship with
They arrive in routine version bumps
Appearing months after the vendor questionnaire, and nobody reviews them.
Your release cadence outruns your evidence.
You ship monthly or faster and test annually, so the document you hold describes an application that no longer exists.
The data that matters sits
after the login screen.
Account balances, payment tokens,
session state, and customer personally identifiable information live on the post-authentication surface, where a source code
scanner has never been.
What changed in 2025 and 2026 that put app inventory in scope?
Mobile app composition moved from a security preference to an inventory obligation on dates
you can check.
Hidden Third-Party SDK Risk: Popular engagement SDKs introduced post-build component flaws that remained completely invisible to app publishers during standard pre-release testing..
April 2026 Microsoft Disclosure: Microsoft Threat Intelligence revealed an intent redirection flaw exposing 50M+ app installs—including 30M+ financial and crypto wallets—to credential and data theft by co-located malicious apps.
Shift to Mandatory Inventory: App store removals and heightened regulatory scrutiny transformed third-party SDK tracking from an optional security best practice into an immediate compliance requirement.
Enforcement Timeline and Key Dates
NowSecure automatically solves this gap by generating an audit-ready Mobile Application Bill of Materials (Mobile App BOM) through automated binary analysis on every build, giving banks the complete, verifiable inventory regulators demand.
Which regulations actually govern a US bank’s mobile app?
A US bank's mobile app answers to four instruments, and only one is the payment cardstandard everyone names first.
The notification rule at 12 CFR Part 53 gives a banking organization just 36 hours to report a computer-security incident once identified.
The Interagency Guidelines Establishing Information Security Standards, at 12 CFR Part 30 Appendix B, are what the Gramm-Leach-Bliley Act requires of a bank: regular testing of the key controls of its information security program. Your examiner assesses that program against the FFIEC IT Examination Handbook. Neither exempts the channel most customers use.
A 36-hour window leaves no time for post-hoc app forensic reconstruction. Meeting this deadline requires pre-established, continuous mobile app activity logs that are ready to pull instantly.
The June 2023 interagency third-party risk guidance is plain: the institution owns the risk of code it did not write. A payment software development kit that quietly changes what it sends off the device is your exposure.
The PCI DSS requirement that matters here is not the one usually cited. Requirement 6.3.2 obliges you to maintain an inventory of your bespoke and custom software and the third-party components inside it.
If you are an insurer rather than a bank, the instrument differs and the obligation does not. The NAIC Insurance Data Security Model Law, adopted in 21 states, requires a licensed entity to maintain an information security program, investigate cybersecurity events, and notify its state commissioner. Your mobile app sits inside that program whether or not anyone has enumerated what it holds.
NowSecure provides the definitive proof that powers your compliance program
By delivering continuous, real-time visibility into your mobile app surface, NowSecure supplies the verifiable audit trails your risk teams need to demonstrate regulatory alignment across GLBA, PCI DSS, and interagency guidelines.
How do you test a banking app after the customer logs in?
Authenticated dynamic analysis drives the app's own login and multi-factor flows on a physical device, reaching the surface that holds account data.
Testing runs on real devices, not emulators, because a banking app behaves differently when the hardware, the keystore, and the operating system are real. The tooling establishes the session itself, so post-login coverage repeats across a release cadence instead of being achievable once a year.
What gets exercised is account, payment, and session behavior on the shipped build rather than a branch.
91% out-of-the-box coverage
100% authenticated success
How does testing survive certificate pinning and root detection?
Standard dynamic scanners stall when encountering certificate pinning (which restricts TLS traffic) or root detection (which halts execution on test environments). NowSecure uses runtime instrumentation to dynamically intercept OS-level API calls during execution, allowing tests to safely bypass defenses and evaluate the app's actual behavior in real time.
| Control | What analysis does |
|---|---|
| Platform-layer certificate pinning | Hooks trust APIs, captures cleartext |
| Native statically linked TLS pinning | Patches the native pinning routine |
| Mutual TLS, client key in hardware-backed keystore | Records endpoints, negotiated TLS, and whether client authentication succeeds |
| Root and jailbreak detection | Bypasses checks so post-login paths run |
| Anti-debug and integrity checks | Traces methods, captures data flow live |
| Obfuscated third-party components | Identifies it, observes runtime data flow |
What AI and third-party code is inside the app right now?
Binary analysis of the shipped application inventories AI components, SDKs, libraries and dependencies, then shows where they connect and where data flows.
The analysis runs against the compiled application you published, not a repository, because
that artifact alone holds what your build pipeline and your vendors' vendors put in.

AUTOMATED COMPLIANCE EVIDENCE
Delivered directly within your Mobile Application Risk Management (MARM) program—not as a standalone AI tool. Mechanically satisfies Requirement 6.3.2 through automated binary analysis rather than manual questionnaires.
How do banks keep mobile security evidence current between releases?
Annual pen tests create immediate compliance gaps. NowSecure automates dynamic security testing inside your CI/CD pipeline, generating timestamped, audit-ready evidence for every build shipped to production.
Continuous pipeline evidence vs. point-in-time audits
Annual pen tests describe software that has already been replaced. Automated CI/CD testing creates a verifiable audit trail for the exact build running in your customers' hands today—answering auditor and fraud team queries instantly with named, dated records.
Automated dynamic testing on every build
Static analysis alone misses runtime risks. NowSecure automatically executes post-login dynamic analysis—testing Network, Authentication, Storage, and Resilience controls—to capture real-time behavior without delaying release cycles.
Mapped to OWASP MASVS Taxonomy
Findings map directly to the industry-standard OWASP Mobile Application Security Verification Standard (MASVS), not a proprietary vendor scale. As co-leads of the OWASP MASTG project, our evidence files speak the exact regulatory language your assessors expect.
Dynamic proof across core security domains
Automated dynamic analysis continuously exercises 5 of the 8 OWASP MASVS domains (Network, Auth, Storage, Resilience, and Platform Interaction), ensuring your security evidence matches the true shelf life of every mobile release.
Continuous automation meets deep human insight
Automated Baseline Enforcement
Dynamic analysis continuously exercises reachable authenticated paths across builds, instantly catching regressions without manual effort.
High-Fidelity Telemetry
Triangulating static, dynamic, and behavioral evidence minimizes false positives, delivering actionable findings developers can fix immediately.
