Mobile App Security Assessment

Mobile applications are at the core of modern digital services — and a prime target for attackers. DEFION’s Mobile App Security Assessment helps your team quickly identify risks, strengthen defenses, and gain confidence in the security of your iOS, Android, or cross-platform apps.

What this service delivers

• Interactive consult (½–1 day): A DEFION security specialist works directly with your developer to assess your mobile app in real time.

• Clear, prioritized findings: Issues categorized by risk level and aligned with your technology stack.

• Practical remediation plan: Recommendations you can implement immediately.

• Concise, tailored report: Summary of current posture, key strengths, and improvement opportunities.

Key focus areas

Our assessment reviews the most critical areas of mobile app security, including:

• Network communication and transport layer security

• Secure storage of sensitive data on the device

• Permissions, access control, and inter-app communication

• Handling of user input and output

• App lifecycle and session management

• Use of third-party SDKs and libraries

• Platform-specific risks (e.g., iOS Keychain, Android intents)

All findings are aligned with the OWASP Mobile Application Security Verification Standard (MASVS).

It’s faster and more collaborative. Instead of a black-box approach, we work directly with your developers to surface risks and fixes in real time.

Do you need source code?
Not required, but access helps. We can work effectively with test builds and staging endpoints.

Which frameworks do you cover?
Native iOS/Android plus Flutter, React Native, and other cross-platform frameworks.

Will this slow down our sprint?
No. The consult is designed to fit within a single sprint and deliver quick wins you can apply immediately.
