Securing Cross-Platform Applications and Beyond


There are many factors to consider when developing a mobile app, including which platforms to support. Some developers choose to release a native app for each platform, while others opt for a cross-platform solution. Which approach is more secure?

Business owners are regularly concerned with the security of cross-platform applications, yet the reality is that it can be prevented entirely with a few safety measures. Sometimes all you need is just an experienced and reliable team of developers. In this blog, Reactron will explain why Cross-platform is no less secure than a Native platform and give you some practical tips to secure your application.


Security overview of Native platform and Cross-platform


There are pros and cons to both native and cross-platform development from a security perspective. Cross-platform apps are more vulnerable to attacks because they are built with web technologies such as CSS, Javascript and HTML, which need a careful approach to security. However, Native apps can be more challenging to secure because they rely on platform-specific features.


Cross-platform frameworks are not inherently less secure than native frameworks for mobile app development. However, there are a few reasons why some people might consider native frameworks to be more confident:


  • Access to native APIs: Cross-platform frameworks often have to rely on third-party libraries or plugins to access certain native APIs, which can introduce additional vulnerabilities. Native frameworks have direct access to these APIs, which can make it easier to build more secure apps.


  • Code execution: Cross-platform frameworks typically use a “interpreted” approach, where the code is interpreted at runtime. This can make it easier for attackers to reverse engineer the app and potentially discover vulnerabilities. Native frameworks, on the other hand, use a “compiled” approach, where the code is compiled into machine code before it is executed. This can make it more difficult for attackers to reverse engineer the app.


  • Performance: Cross-platform frameworks can sometimes have performance issues, which can make it easier for attackers to launch certain types of attacks (e.g. denial of service). Native frameworks generally have better performance, which can make it harder for attackers to launch these types of attacks.


It’s time to let the myth go! The potential of cross-platform applications is boundless.


There are a few reasons why cross-platform frameworks are not inherently less secure than native frameworks for mobile app development:


  • Improved security in recent years: Cross-platform frameworks have come a long way in recent years in terms of security. Many of the security issues that were present in earlier versions of these frameworks have been addressed, and modern cross-platform frameworks offer a number of security features that can help developers build secure apps.


  • Security depends on the framework and how it is used: The security of a cross-platform app depends on the framework being used and how it is used, rather than the fact that it is a cross-platform app. A well-designed cross-platform framework that is used correctly can be just as secure as a native framework.


  • Security depends on the specific app: The security of a mobile app also depends on the specific app itself and how it is designed and implemented. Even if a native framework is used, an app can still be vulnerable if it is not designed and implemented with security in mind.

Developing a secure cross-platform app requires careful consideration and implementation of the right technologies. Selecting the optimal framework and ensuring regular updates are essential for optimal performance to save peace of mind. Hence, partnering with a reliable software development company which also offer maintenance can help you navigate the process and create a secure product.



Practical tips to secure your Cross-platform application


It’s important to note that these are generalizations and there are many factors that can affect the security of a mobile app. The best way to ensure the security of a mobile app is to follow best practices for mobile app development, regardless of the framework being used. Here are some specific steps you can take to develop a secure cross-platform application:


  • Use a secure cross-platform framework: Choose a cross-platform framework that has a good track record for security and is actively maintained by the developer community. Some good examples: Flutter and React Native- Why Cross-platform and why React Native


  • Keep the framework and any third-party libraries or plugins up to date: Make sure to regularly update the framework and any third-party libraries or plugins to the latest version to ensure that you have the latest security fixes.


  • Use a secure development process: Follow a secure development process, such as the OWASP Mobile Security Testing Guide, to identify and fix potential vulnerabilities in your app. The Reactron team is equipped with the knowledge and capabilities to ensure secure development processes are followed. It helps to ensure compliance with industry regulations and standards, as well as providing visibility into security issues and allowing for more rapid resolution of any issues that may arise. Reactron is dedicated to providing a secure product to our customers by following secure development methods to deliver on that promise.
  • Use secure communication channels: Use secure communication channels (e.g. HTTPS) to transmit sensitive data, and consider using encryption to protect data in transit and at rest.


  • Test the app for vulnerabilities: Regularly test the app for vulnerabilities using tools such as static code analysis, dynamic analysis, and penetration testing.


  • Monitor the app for security issues: Monitor the app for security issues and take prompt action to fix any vulnerabilities that are discovered.


By following these steps, you can help ensure the security of your cross-platform app. It’s important to note that these are general guidelines and the specific steps you need to take will depend on the specific requirements of your app and the framework you are using.



The advantages that come with cross-platform development are too great to ignore! Not only will it help business owners reduce time-to-market, but they can also create their products with greater cost-efficiency. For the best possible outcome, it is essential to assemble a detail-oriented team of developers with the expertise to build a powerful back-end for your cross-platform app. The knowledgeable one must be able to implement a robust back-end for your cross-platform app, making it both secure and efficient, as well as scalable.
