8 Best Mobile Application Security Testing Tools (Free And Paid)

Today’s mobile apps are a standard part of our everyday lives and a critical link between businesses and their customers, but they are complex!

They have evolving backend architectures with various elements, such as legacy codebases, public APIs, and decoupled microservices. 

Therein lies an opportunity for hackers.

Did you know that 83% of both web and mobile apps have at least one security flaw? In fact, according to Deloitte, almost 60% of vulnerabilities reported during a mobile app security assessment are classified as “day zero.”

Safeguarding apps through mobile application security testing tools is, therefore, necessary because of the sensitive user data at stake.

Features to Look for in Mobile App Security Testing Tool

When selecting a mobile app security testing tool, it’s crucial to consider a range of features and capabilities to ensure comprehensive testing and protection of your mobile applications. Here are some important features to look for:

1. Static and Dynamic Analysis:

Static analysis tools can identify potential security vulnerabilities by analyzing the code itself. Examples of vulnerabilities detected through static analysis include code injection, insecure data storage, and hard-coded credentials. It’s crucial for early detection during the development phase.

Conversely, dynamic tools interact with the app as a user would, exploring various paths and inputs to identify vulnerabilities that may only manifest during runtime. Common findings include issues related to authentication, session management, and network communication security.

2. Code Scanning

Code scanning tools focus specifically on the app’s source code. They analyze the codebase for potential vulnerabilities, coding mistakes, and adherence to secure coding standards such as SQL injection, Cross-Site Scripting (XSS), and improper input validation.

3. Penetration Testing:

Pentesting helps identify critical security flaws that may not be easily detectable through automated tools. Common findings include vulnerabilities like weak authentication, insecure API endpoints, and privilege escalation vulnerabilities.

4. Automation and Continuous Integration (CI) Support:

Look for a tool that can be easily integrated into your CI/CD pipeline and existing tech stack. This ensures that security checks are performed consistently with every code change and build. Automation helps catch vulnerabilities early, reduces the risk of introducing new security issues, and accelerates the delivery of secure mobile apps.

5. Customer Support & Community

A robust user community can be immensely valuable in terms of sharing knowledge, best practices, and user-generated scripts or plugins that enhance the tool’s functionality. It also provides a platform to discuss common challenges and solutions with other users who may have encountered similar issues. Furthermore, responsive and knowledgeable customer support from the tool’s developers or vendors is essential.

6. Cost and Licensing:

Thoroughly examine if the cost of the tool aligns with your budget. Consider whether the tool offers a free trial or a limited-feature version for initial testing and evaluation. Beyond the initial cost, also assess whether the tool’s pricing scales with your usage and whether there are hidden costs, such as additional fees for technical support or updates.

What is Mobile Application Security Testing (MAST)?

MAST refers to examining mobile apps to identify issues that could compromise data confidentiality, integrity, and availability within or transmitted to and from the app. This is done via various testing methods, such as code review, static/ dynamic analyses, and penetration testing.

Why is mobile app security testing necessary?

Security testing of mobile apps is essential as:
1. It anticipates the behavior of cyber attackers and identifies vulnerabilities.
2. It spots all security weaknesses before an app is launched, enabling you to deliver a safe user experience.
3. It ensures the mobile app adheres to all legal compliances and industry security standards.

How can you use a mobile app security scanner to protect your business?

First, choose a reputable scanner that suits your needs. Once installed, start scanning to assess the app’s code and data flows. The scanner will pinpoint vulnerabilities like data leaks or weak encryption. Fix these flaws as per the recommendations. Regularly update and rescan the app to ensure ongoing protection.
