Penetration testing your iOS or Android app isn't optional anymore—it's mandatory insurance against data breaches and regulatory fines. The cost varies wildly depending on app complexity, scope, and tester credentials, but understanding the pricing model upfront saves budget headaches and prevents hiring underqualified testers.
Why Mobile App Penetration Testing Costs Vary
Mobile penetration testing isn't a flat-rate service. A simple utility app with minimal backend integration costs far less than a fintech or healthcare app handling sensitive data. Testers charge based on engagement scope: whether they're testing just the client-side app, integrating with your backend APIs, or simulating attacks across the entire attack surface.
The penetration testing model itself matters. Time-and-materials engagements (hourly or daily rates) range from $150–$300 per hour for mid-level testers to $300–$500+ for OSCP-certified or specialized mobile security experts. Fixed-scope projects typically cost $5,000–$50,000 depending on app complexity and testing duration.
iOS Penetration Testing Costs
iOS apps generally cost 10–20% less than equivalent Android tests because Apple's closed ecosystem reduces attack vectors. A baseline iOS security assessment—covering authentication, data storage, API communication, and local vulnerabilities—runs $8,000–$25,000 for 2–4 weeks of testing.
Factors that push costs higher include:
- Advanced jailbreak detection bypass testing
- Secure Enclave and biometric authentication security review
- Complex integration with Apple services (CloudKit, HealthKit)
- Custom cryptographic implementations requiring specialized review
If you're only testing the app's network traffic and basic input validation, expect $6,000–$12,000. Enterprise apps with complex backends and regulatory compliance needs (HIPAA, PCI-DSS) typically fall into the $20,000–$45,000 range.
Android Penetration Testing Costs
Android testing tends to be more expensive because the open platform expands the attack surface. Rooting, installing custom ROMs, and patching security mechanisms are straightforward, which means testers need more time and expertise to simulate real-world attacks comprehensively.
A standard Android penetration test costs $10,000–$30,000 for similar scope and timeline as iOS. Rooting and runtime instrumentation testing, bytecode manipulation, and frida-based dynamic analysis add $3,000–$8,000 depending on complexity.
Additional cost drivers for Android include:
- Testing across multiple API levels and device variants
- Sandbox escape and privilege escalation scenarios
- Custom ROM and kernel-level vulnerability assessment
- Reverse engineering of obfuscated code (if needed)
Larger organizations often budget $25,000–$50,000+ for comprehensive Android security assessments that include supply chain risk and third-party SDK vulnerability scanning.
What's Actually Included in the Price
A credible mobile penetration test covers these core deliverables:
- Static analysis: Decompiling, reviewing source code logic, and identifying hardcoded secrets or misconfigurations
- Dynamic analysis: Running the app in a test environment, intercepting traffic, and triggering vulnerabilities
- Network testing: Assessing API endpoints, SSL pinning, and backend communication security
- Data storage review: Checking how credentials, tokens, and user data are persisted
- Authentication and session management: Testing for bypass techniques, token theft, and privilege escalation
- Third-party library scanning: Identifying vulnerable open-source dependencies
- Detailed report with proof-of-concept exploits: Not just vulnerability lists, but actionable remediation steps
Avoid testers who price below $5,000 for full-scope testing—that's usually a sign they're cutting corners on thoroughness. Similarly, pricing above $150,000 for a single app without clear enterprise justification suggests inefficiency.
Timeline and Re-Testing Costs
Initial assessments typically take 3–6 weeks. Retesting after remediation usually costs 30–50% of the original engagement fee and takes 1–2 weeks. Many providers include one round of retesting in their fixed-price contract, so clarify this upfront.
Finding and Comparing Qualified Testers
Look for testers holding relevant certifications: OSCP, GWAPT (GIAC Web Application Penetration Tester), or CEH with mobile specialization. Ask for references from companies in your industry—a tester experienced with fintech apps will spot risks a generalist might miss.
Tools like Mercoly let you compare and find trusted penetration testing and vulnerability assessment providers in one place, making it easier to vet expertise, pricing, and past work.
Frequently Asked Questions
Q: Can I use automated vulnerability scanning tools instead of hiring a penetration tester? Automated scanners catch obvious misconfigurations but miss logic flaws, authentication bypasses, and creative exploit chains that manual testing finds; most compliance frameworks require human-led penetration testing anyway.
Q: How often should I repeat penetration testing? Annual testing is standard; test again after major app updates, new feature releases, or security incidents, and always retest after fixing critical vulnerabilities.
Q: What's the difference between a pentest and a vulnerability assessment? A vulnerability assessment scans and reports weaknesses (cheaper, 2–5 days); a penetration test actively exploits those vulnerabilities to measure real impact (more expensive, 2–4 weeks, higher value).
