The Most Critical Mobile App Security Tips for Application Development Companies

Thanks to overabundance of application development companies, mobile app developers worldwide are constantly feeling the heat of competition. Mobile app security is now an important factor for all of them to stay competitive. As businesses are increasingly going mobile, protecting consumer data and privacy has become a high priority for brands.

So, when building a mobile app, you need to give optimum focus and priority on app security more than anything else. You need to create apps that make users feel at complete ease. This is why we are going to explain some of the key considerations that can boost your mobile app security.

Go for practical and feasible security solution

If you want a quick checklist to ensure data security for all types of apps, let us tell you that there is no such thing. The security checklist for every different app is different. Since some apps are less vulnerable to security threats and data breaches and some apps are extremely exposed to security vulnerabilities, you cannot adopt the same security measure for all types of apps. You need to figure out the security measure and practical security solution for every different kind of app.

For example, a simple productivity app like an alarm clock may not be that vulnerable to security threats, and hence you need minimal security measures for such an app. In contrast, for an app with remote data transfer and real-time streaming feature, there will be a lot of data security considerations and risks. All these mobile apps rely heavily on remote servers for crucial data transfer and communication and should have more safeguards compared to the less complicated and local apps. From this, it is quite evident that the one-size-fits-all approach is no longer effective for app security.

Using transit encryption for credential and sensitive data

Some data and activities that your app handles are more vulnerable to security threats than others. You need to be extra vigilant about them. For example, user credentials like the username, password, API keys and similar types of sensitive user data are always exposed to different types of security risks. Such data require transit encryption. By using transit encryption whenever data passes through unreliable and untrustworthy networks, interception and any intrusion can be completely prevented.

To ensure this, you do not need an expensive solution. You can just opt for HTTPS and additionally go for a digital certificate. You also have to make sure that the certificate is checked by the app properly and regularly. Apart from following this standard, always keep watch on the fast-evolving security standards and practices. You should always opt for most updated and acclaimed security practices as and when they become available.

Using appropriate testing software

As a mobile app development company, you need to give attention to the testing software and solutions that are in the market. While there are many options in the market, you need to fully ensure the quality of the testing software and its performance in dealing with security flaws. You may not want to opt for a testing software that has just been launched, and has been barely reviewed by anyone. It is always advisable to choose a security software that is used by your major competitors and have a good reputation.

Embrace the perfect security strategy for your API

API and mobile app development are always closely connected, and the security considerations for one are bound to affect the other. This is why, to ensure optimum security for a mobile app, you have to ensure the security of the API as well. APIs help to transmit data among different parties and naturally, any security vulnerability with the API can affect various connected apps in the process. You need to embrace the right strategy and practice to ensure optimum security for the APIs you are going to use and integrate.

Give optimum care for consumer data

What is the most vulnerable element for any mobile app? Well, it is mostly consumer data. The security risks concerning consumer data can actually have a disastrous effect on the reputation of an app. This is why it is something no development company can play with. Normally, the higher the volume of consumer data an app is going to handle, the more vulnerabilities it needs to handle.

New data encryption technologies and biometric authentication can to a large extent cover the regular security vulnerabilities concerning customer data. And decentralised database technology like the blockchain has arrived with never-before promise to safeguard data from all types of intrusions and security risks.

Optimize the code

Finally, we are going to talk about the most significant security measure for most mobile apps. Yes, it is the unorganized and unclean code that often causes a lot of data security risks. The most important thing is to write concise, clean and well-organized code that doesn’t create a substantial burden on the application. To optimize the code, consider the following tips.

  • Take care of all the unused or irrelevant pieces of code and the spaces that are creating a burden on the memory and even allowing outside flaws to thrive in.
  • Don’t use libraries that don’t show coding errors. Sweeping your coding flaws under the carpet will only pull down your effort and make security more vulnerable to risks.
  • The most important thing to optimize the code for optimum security is to follow the best coding practices and avoid common mistakes. The key practices that any app developers should incorporate include a thorough test-driven development and concurrent code testing, robust quality assurance process and deployment automation.


Finally, always make sure you use only the plugins and extensions from the respective CMS store that are widely acclaimed and do not have security glitches. Following best practices and the tips mentioned above, we can to a large extent reduce the common security flaws for any mobile app.
