Data security in low-code platforms: Why it's critical

Common security risks and challenges

Low-code platforms offer huge benefits for digital transformation — but they're not immune to security risks. It becomes particularly critical when applications are created and used productively without in-depth IT knowledge. The following are the key challenges that arise when using low-code solutions in terms of data security and what you should pay attention to.

Lack of “privacy by design”

Many citizen developers focus primarily on functionality — security aspects quickly take a back seat. It is crucial to integrate data protection measures into the application right from the start (“privacy by design”). In practice, however, this often lacks time, know-how or clear guidelines. As a result, security gaps arise as early as the design phase.

Tip: Make sure that your platform technically supports data protection principles — such as automated data masking, audit logs, or access controls.

Unclear responsibility for safety standards

In classic development projects, the responsibility for security clearly lies with the IT department. In low-code projects involving specialist departments, these responsibilities become blurred. If you do not coordinate early, you risk misconfigurations or violations of compliance requirements.

Tip: Define clear roles and responsibilities. Ideally, citizen developers work closely with IT security experts or data protection officers.

Limited transparency in data processing

Another problem: Many developers — whether experienced or not — do not know exactly which data is being processed, how long it may be stored or what legal framework applies. Without this knowledge, it is hardly possible to make applications compliant with data protection regulations.

Tip: Promote training for all parties involved and integrate data protection information into your project planning.

Risk from third-party modules and foreign code

Low-code platforms often allow plug-ins or external code to be integrated — a potential gateway for attacks. If this code is not thoroughly checked, malware can enter the application unnoticed or undermine existing security measures.

Tip: Conduct regular code reviews and security analyses, either manually or using automated tools. Only use proven, trustworthy extensions.

Uncertain architecture and development processes

The principles of secure software development also apply to low-code projects: a robust application architecture, clear access control, encryption and logging. But structured development processes such as a Secure Development Lifecycle (SDLC) are often missing because the focus is on rapid implementation.

Tip: Use platforms that include a secure architecture framework — including role-based access models, authentication mechanisms, and audit functionalities.

Software supply chain attacks

Supply chain attacks are increasing — even in the context of low-code. This is where attackers manipulate components or third-party services that are integrated into your application. Particularly dangerous: These gaps often remain undetected for a long time.

Tip: Rely on platforms with a transparent development process, regular security updates and clear communication in the event of incidents.

Lack of security awareness among citizen developers

A key point: Many low-code users are not IT security experts. This results in insecure configurations, lack of encryption or inadequate allocation of rights. In practice, this creates an increased risk of data breaches.

Tip: Train your citizen developers specifically in IT security and data protection. Even a brief security onboarding can help prevent serious mistakes.
