FRAUD AND REGULATORY RISKS

Financial apps face rising attacks and compliance repercussions

Successful mobile fraud attacks can extract hard-coded secrets, bypass KYC controls and trigger regulatory fines and negative publicity.

  • Protect against credential theft and unauthorized account access
  • Stop malicious actors from bypassing KYC and authentication controls
  • Prevent API abuse from bots, scripts, and repackaged clones

MOBILE SECURITY AND COMPLIANCE

FinTech apps need multilayered fraud protections

Scan your code for vulnerabilities, implement strong protections including advanced code hardening and RASP checks, and apply dedicated mobile API security to protect your backend servers.

  • Prevent mobile app cloning and tampering with in-depth code hardening and runtime security checks (RASP)
  • Ensure only legitimate devices are interacting with your APIs
  • Maintain compliance with mandates and regulatory requirements like PCI MPoC,PSD2 and PSD3

Secure financial apps and SDKs

Protect your mobile app and find security issues quickly

Mobile FinTech developers need to ensure the highest levels of integrity for financial transactions and user accounts. Guardsquare combines in-depth mobile app testing with multi-layered protections to prevent fraud and maintain regulatory compliance.

AppSweep continuously scans your mobile app, surfacing both static and dynamic security issues. Pipeline-integrated testing enables you to fix issues early in the development process, reducing the time and cost of remediation. Findings are mapped to OWASP industry standards to help you prioritize high-severity issues.

DexGuard (Android) and iXGuard (iOS) apply in-depth protection against reverse engineering and runtime tampering of mobile apps and SDKs. Sensitive code is hardened with different forms of obfuscation and encryption, while RASP checks ensure the integrity of your code and its environment during runtime.

Guarantee the authenticity of each app interacting with your mobile APIs

With Guardsquare’s advanced app attestation capabilities, developers can ensure that any mobile app calling their APIs is authentic and untampered.

Policy-based controls allow you to block automated bots, malicious scripts, and non-genuine apps from interaction with backend services. App attestation also gathers insights about the behavior of users and their devices, helping security teams fine-tune policies on-the-fly, without rebuilding the application.

FinTech Mobile App Security TL;DR

Yes, Guardsquare’s in-depth, multi-layered protections can help FinTech organizations meet compliance and regulatory goals such as PSD2, PSD3, and PCI.

FinTech mobile apps are prime targets for fraud attacks, and can carry significant compliance risks. That is why a compiler-based approach with multiple layers of protection provides the best defense against ever-evolving threats.

Credential theft via malware, fake or cloned apps distributed through phishing campaigns, and runtime manipulation (e.g., hooking or injection) are some of the most common attacks against FinTech mobile apps. Guardsquare provides multi-layered protections against both static and dynamic analysis, largely mitigating these threat vectors.

Android and iOS both provide sandboxing and permission controls to protect the user and their device. But they do not protect your compiled application code from being reverse engineered, modified, or instrumented at runtime. That is why an in-depth, dedicated mobile application security strategy is essential.

Guardsquare's protections have negligible impact on app size and performance in most cases. FinTech clients generally report no measurable degradation in startup time or responsiveness of their mobile app.
