Protecting Your Mobile Apps From Real Threats

We've spent the last eight years watching apps get compromised because someone thought security was something you add later. It's not. When your mobile app handles user data, payment info, or business logic, you need protection built into every layer from the start.

Our Approach

Security That Actually Fits How Apps Work

Most security consultants hand you a checklist and walk away. We dig into your specific architecture, understand your data flow, and build protections that work with your app's performance needs instead of against them.

Code-Level Security Analysis

We review your actual codebase, not just scan it with automated tools. This means finding logic flaws that scanners miss and understanding context around potential vulnerabilities.

  • Manual review of authentication flows
  • API endpoint security validation
  • Data handling and storage checks
  • Third-party library audit

Runtime Protection

Your app faces different threats when it's running on someone's phone than it does in your test environment. We implement monitoring and protection that works in the real world.

  • Certificate pinning implementation
  • Runtime tampering detection
  • Secure key storage configuration
  • Network traffic encryption

Backend Integration Security

Your mobile app is only as secure as its weakest connection point. We examine how your app communicates with servers, handles tokens, and manages sessions across network conditions.

  • Token refresh mechanism review
  • Rate limiting configuration
  • Error handling that doesn't leak info
  • Secure session management

How We Actually Work With You

Security isn't a one-time fix. It's an ongoing process that needs to adapt as your app grows and threats change.

Here's what working with us looks like in practice, based on what we've learned from securing apps across fintech, healthcare, and e-commerce sectors throughout Taiwan since 2020.

1

Initial Security Assessment

We start by understanding what you're protecting and why. Not every app needs the same level of security, and over-engineering can hurt performance.

Real example: A payment app we worked with in early 2024 needed biometric authentication and encrypted storage. A content streaming app from the same client needed different protections focused on preventing video piracy and account sharing.
2

Threat Modeling For Your Use Case

We map out realistic attack scenarios based on your app's functionality and user base. This helps prioritize what to protect first.

What this means: If you're building a shopping app, we focus on payment data protection and preventing cart manipulation. For a social platform, we look at account takeover prevention and content moderation bypass attempts.
3

Implementation Support

Security recommendations are useless if they're too complex to implement. We work alongside your developers to integrate protections without breaking existing functionality.

How we helped: When implementing certificate pinning for a logistics app in September 2024, we created a fallback mechanism that prevented the app from breaking if certificates needed emergency rotation. This saved them during an unexpected SSL provider migration.
4

Ongoing Monitoring Setup

We configure alerts for suspicious activity and establish response procedures. This includes deciding what warrants immediate action versus what can wait for weekly review.

Practical application: For a healthcare app, we set up alerts for multiple failed authentication attempts, unusual data access patterns, and API calls from unexpected geographic regions. These caught three attempted account takeovers in Q1 2025.

Threats We've Seen Actually Happen

These aren't theoretical. Each of these attack types has hit apps we've either secured or been called in to fix after the fact.

Man-in-the-Middle Attacks

Attackers intercept traffic between your app and server, usually on public WiFi. They can read data, modify requests, or steal authentication tokens.

Our Protection: We implement certificate pinning and enforce TLS 1.3 with proper cipher suites. We also add integrity checks on critical API responses so tampering gets detected immediately.

Reverse Engineering

Someone downloads your APK or IPA, decompiles it, and examines your code to find vulnerabilities, extract API keys, or understand business logic they can exploit.

Our Protection: Code obfuscation, string encryption for sensitive values, and root/jailbreak detection. We also implement integrity checks that verify the app hasn't been modified.

Injection Attacks

Malicious input that tricks your app or backend into executing unintended commands. This includes SQL injection, command injection, and path traversal attempts.

Our Protection: Input validation on both client and server, parameterized queries, and proper encoding of user data. We test with actual attack payloads to verify defenses work.

Session Hijacking

Stealing or predicting session tokens to impersonate legitimate users. This often happens through XSS, insecure storage, or token leakage in logs.

Our Protection: Secure token generation with proper entropy, encrypted storage using platform keychains, short token lifetimes with refresh mechanisms, and session binding to device characteristics.

Get A Realistic Security Assessment

We'll review your app's architecture, identify actual vulnerabilities based on how attackers target mobile apps in 2025, and give you a prioritized plan that fits your budget and timeline. No scare tactics, no selling you things you don't need.
