That growth comes with a cost. Mobile-banking Trojans hit 247,949 users globally in 2024, up from 69,200 the year before, according to Kaspersky's 2024 Financial Threat Report. Saudi Arabia isn't immune to this trend, and regulators know it.
This is where mobile application security assessments come in. They give BFSI and government app teams a structured way to find vulnerabilities before attackers do. This article covers what these assessments involve, what they uncover, and how to pick a partner that actually understands high-stakes mobile risk.
Key Takeaways
- Saudi Arabia’s 99% smartphone penetration makes mobile the primary channel for banking, fintech, and government services
- Electronic payments hit 85% of retail transactions in 2025, expanding the attack surface for financial apps
- OWASP MASVS is the global standard for structuring mobile security assessments
- PDPL and SAMA compliance both require demonstrable, recurring mobile app testing
Why Mobile Application Security Matters in Saudi Arabia
Saudi Arabia has reached 99% smartphone penetration, per the World Economic Forum. Online banking usage sits at 85.9%, according to the Saudi Internet Report 2025. That's not a niche behavior anymore. It's the default.
Electronic payments made up 85% of total retail transactions in 2025, up from 79% in 2024, per SAMA. Add a fintech sector expected to grow to 525 companies by 2030 (from 224 in 2024, per the Saudi Press Agency), and the mobile attack surface widens fast.
What's at Stake
Every new banking feature, e-wallet integration, or government e-service app is another entry point for attackers. A breach doesn't just cost money. It triggers:
- Regulatory penalties under PDPL and SAMA frameworks
- Customer churn in a market where trust drives app adoption
- Reputational damage that's hard to reverse in a small, connected banking sector
Vision 2030's digital push is a growth story. It's also a bigger target for fraud rings and malware operators who've already shown interest in regional mobile-banking ecosystems.
What Is a Mobile Application Security Assessment?
A mobile application security assessment is a structured evaluation that identifies vulnerabilities, misconfigurations, and design flaws in a mobile app before they become breaches. It's broader than a single scan.
Three distinct activities often get lumped together, but they're not the same:
- Vulnerability scanning — runs automated checks for known issues; fast, but prone to false positives
- Penetration testing — simulates real attacks through manual, targeted exploitation
- Full security assessment — combines static analysis, dynamic testing, architecture review, and business-logic evaluation
Static vs Dynamic Analysis
Static analysis reviews the app's code or compiled binary without running it. Testers look for hardcoded API keys, insecure local storage, and weak cryptography choices baked into the build.
Dynamic analysis takes the opposite approach. It watches the app behave in real time, examining session handling, server communication, and how data moves between the device and backend.
Both matter. Static analysis catches what's baked in; dynamic analysis catches what only shows up when the app is actually running.
OWASP MASVS & MASTG Framework
The Mobile Application Security Verification Standard (MASVS) is OWASP's industry benchmark for mobile app testing. It organizes controls into eight groups: storage, cryptography, authentication, network communication, platform interaction, code quality, resilience, and privacy.
Its companion guide, the Mobile Application Security Testing Guide (MASTG), describes exactly how testers verify each control, including reverse-engineering techniques for both Android and iOS.
As of MASVS v2.0.0, the older L1/L2/R verification levels were retired in favor of risk-based MAS Testing Profiles. Any vendor still pitching a rigid "Level 1 vs Level 2" checklist may be working from outdated methodology.
What's Included in a Comprehensive Mobile App Security Assessment
A thorough assessment covers far more than the app's front end.
Core areas typically assessed:
- Authentication and session management, including OTP flows and token handling
- Data storage and encryption, both at rest and in transit
- Network communication security, checking for man-in-the-middle exposure
- API security, since most mobile risk actually lives on the backend
- Code quality, obfuscation strength, and anti-tampering resistance
For apps handling financial transactions, reverse-engineering resistance matters as much as the code itself. Testers attempt to decompile the app, bypass root/jailbreak detection, and see how easily business logic can be extracted or manipulated.
Protectt.ai's AppProtectt platform monitors these threats continuously at runtime—reverse-engineering attempts, tampered APK submissions, and screen-mirroring activity as they happen.
Backend and API testing deserves equal weight. Attackers rarely limit themselves to the mobile client. They'll pivot to whatever API the app talks to. Assessments should test authentication tokens, rate limiting, and data exposure across every API endpoint the app touches.
Deliverables That Actually Matter
A useful assessment report includes:
- A vulnerability list with clear technical detail, not just a scanner printout
- Risk prioritisation, weighing exploit likelihood against business impact
- A remediation roadmap with specific, actionable fixes for development teams
One-time audits go stale fast. New OS versions, new libraries, and new attack techniques mean assessments need to repeat on a cycle, not just before launch.
Common Mobile App Vulnerabilities Facing Saudi Enterprises
Some vulnerability patterns show up repeatedly in financial mobile apps. Positive Technologies' analysis of banking apps found that 48% had at least one critical vulnerability, and 65% suffered from insecure data storage or weak brute-force protection. The same gaps put Saudi banks, fintechs, and government apps at risk as mobile channels scale.
Insecure data storage and weak encryption
Apps that cache sensitive data locally without proper encryption expose customer records if a device is lost, stolen, or compromised by malware.
Authentication and OTP weaknesses
Client-side authentication checks, weak session timeouts, and OTP interception are common exploit paths. Fraudsters increasingly target SMS-based OTPs directly, which is why silent, no-OTP verification approaches (such as SIM-network handshakes) are gaining traction as an alternative.
Insecure APIs and third-party library risk
Third-party SDKs and outdated libraries introduce supply-chain risk that is invisible from the app's UI. Insecure APIs can leak account data even when the mobile client itself looks secure. In Positive Technologies' financial-app research, 52% of mobile banking apps had issues that allowed credential interception or full authentication bypass.
Regulatory Compliance and Data Protection in Saudi Arabia
Saudi Arabia's Personal Data Protection Law (PDPL) applies to any entity processing personal data of individuals in the Kingdom, even from outside its borders. Controllers must implement organizational and technical safeguards, and violations can carry fines up to SAR 5 million, or up to SAR 3 million for unlawful disclosure of sensitive data.
SAMA's Cyber Security Framework goes further for regulated financial entities, requiring:
- Multi-factor authentication for electronic banking transactions
- Penetration testing or independent code review during change management
- Data separation, mobile device management, and encryption for corporate apps
- Secure wiping protocols after device loss or decommissioning
Regular, documented mobile app security assessments are the practical way BFSI institutions demonstrate this compliance to regulators, rather than scrambling to prove it after an incident.
A platform-based approach adds ongoing value beyond a point-in-time test. Protectt.ai's mobile app security platform, built on ISO 27001, ISO 22301, and PCI DSS certifications, layers real-time monitoring on top of assessment findings.
Its RASP engine (AppProtectt) delivers 100+ controls that help BFSI teams sustain compliance between audits:
- End-to-end encryption for data at rest and in motion
- Continuous detection of tampering, rooted devices, and man-in-the-middle attempts
- Runtime defenses that keep evidence current for regulators
That shift—from "we passed an audit" to continuous monitoring—matches what mature SAMA and PDPL programs expect day to day.
Choosing the Right Mobile App Security Assessment Partner
Not every vendor tests to the same depth. Before signing a contract, check for these specifics.
Evaluation criteria:
- Framework alignment — Does the partner map findings to current MASVS v2.0.0 controls, or are they still quoting outdated L1/L2 levels?
- BFSI/fintech experience — Have they tested apps handling real transaction data, not just generic consumer apps?
- Testing depth — Do they combine static, dynamic, and manual penetration testing, or just run an automated scanner?
Point-in-time testing is only part of the decision. After the assessment, you still need runtime protection that fits how your teams ship software:
- Low false-positive rates, so development teams aren't chasing phantom issues
- Minimal performance overhead once protections are deployed
- SDK integration that doesn't derail release schedules
Protectt.ai's lightweight SDK integrates into existing Android and iOS apps without disrupting development cycles—validated in production with BFSI clients such as Equitas Small Finance Bank.
The platform adds RASP, code protection, and fraud controls that keep mobile apps defended after the assessment ends, and is available to banks, insurers, and government-facing apps serving Saudi Arabia and the wider region.
Conclusion
With smartphone penetration close to universal and electronic payments carrying most retail spend, a Saudi mobile app is the front door to the institution behind it. MASVS gives an assessment its structure — architecture, storage, cryptography, authentication, reverse-engineering resistance, each with remediation you can track — and PDPL and SAMA both expect that work to recur and to be demonstrable, not commissioned once and cited for two years.
Recurring is still not continuous. Production drifts between engagements: new OS versions, new libraries, new techniques, and a build that has changed several times since the assessor last looked at it.
Protectt.ai supplies the runtime half of that model. RASP keeps an assessed app honest once the testers leave, with tamper and root checks running continuously, abuse is blocked on the device with no server hop, and telemetry produces the recurring evidence a SAMA-aligned programme is asked for. The SDK ships at no measurable UX cost. Teams across the Kingdom pair MASVS-style assessments with it as standard practice.
Plan the next assessment cycle, then book a demo for the months it will not cover.
Frequently Asked Questions
What are the security considerations for mobile apps?
Key considerations include secure data storage, strong authentication and session management, encrypted network traffic, and API security. Apps also need defenses against rooting, jailbreaking, and reverse engineering—especially in financial use cases.
What is included in a security assessment?
An assessment typically combines static code analysis, dynamic runtime testing, vulnerability scanning, and manual penetration testing. It ends with a prioritized report and a remediation roadmap for development teams.
How often should a mobile app security assessment be conducted?
Assessments should happen during development, before every major release, and periodically after launch. Given how fast new vulnerabilities and OS versions emerge, annual testing alone usually isn't enough for high-risk financial apps.
Is mobile app security assessment mandatory for banks and fintechs in Saudi Arabia?
SAMA's Cyber Security Framework requires regulated entities to conduct security testing, including penetration testing, during change management. PDPL compliance also expects demonstrable data protection safeguards, which assessments help demonstrate.
What is OWASP MASVS and why does it matter?
MASVS is OWASP's global standard framework for mobile app security verification, covering areas like storage, cryptography, authentication, and network security. It gives testers and developers a consistent methodology instead of an ad hoc checklist.
How long does a mobile application security assessment take?
Timelines vary by app complexity, but most assessments take anywhere from a few days for a narrow scope to several weeks for a full-stack review covering client, API, and backend components.
