Development of the SINEC Security Inspector
Case Study by makandra

Description
Since 2016, we have been supporting Siemens in the development of the SINEC Security Inspector. This tool is used to identify vulnerabilities in industrial plants and products. We are responsible for developing secure and user-friendly web interfaces that enable devices to be checked for cyberattacks.
Solution
We implemented the web application with Ruby on Rails, placing particular emphasis on security. Technologies such as Docker and KVM are also used for virtualization. Once configured, the tool delivers automated test programs and presents the results in an intuitive traffic light system. These highlight potential security vulnerabilities and illustrate recommended measures for network operators directly.
Results
The collaboration has resulted in a stable application that identifies and resolves security issues. Siemens values our ability to find solutions to complex problems.

We work in the public sector for the State of Berlin in the field of health promotion and prevention. The goal of the website is to publicize and clearly present physical activity programs in Berlin. Makandra fully met the requirements of the request for proposals and submitted a clear concept for service delivery, thereby winning the contract for the project. The success of the website can be described by the fact that it is unique to Berlin. A site that lists all free exercise opportunities in every district, complete with an exercise map and calendar, did not previously exist. Our collaboration has been characterized by very productive and friendly communication. Makandra responds quickly to issues and finds solutions.
We work in the public sector for the State of Berlin in the field of health promotion and prevention.
The purpose of the website is to promote and provide a transparent overview of physical activity opportunities in Berlin. To make this information as clear and easy to navigate as possible, a dynamic site featuring an activity calendar and map was developed, which uses various search functions to display all available physical activity opportunities.
Makandra fully met the requirements of the request for proposals, submitted a clear and detailed proposal for service delivery, and was therefore awarded the contract.
Our collaboration has always been characterized by open communication and a willingness to help. Coordination takes place via email or during regular meetings. Whenever changes were made to the website, they were first released on a staging platform so that the relevant departments in the State of Berlin could review them. Requested revisions were implemented quickly and without any issues.
There was an employee who always served as the point of contact and developer for the website design.
The success of the website can be attributed to the fact that it is unique in Berlin. There is currently no other site that lists all free exercise programs in every district, complete with a map and calendar.
Deadlines were met, and close consultation took place whenever changes to the schedule arose.
Our collaboration is characterized by very productive and friendly communication. Makandra responds quickly to issues and finds solutions.
We have been very satisfied so far and have no suggestions for improvement. Working with you has been a pleasure.
The project goal was to pre-populate recurring documentation templates with a changing dataset. Requirements included flexible templates, various input types, and variable layouts—all within the constraints of an air-gapped infrastructure. In developing the software, the provider not only does the bare minimum but is always willing to go the extra mile. Automated tests, UX improvements, and suggestions for enhancement are rarely found to this extent. The service provider responded very flexibly to frequently changing requirements and even supported us in establishing a predictable requirements management process.
MT Aerospace is a leading global aerospace company specializing in lightweight structures made of metal and composite materials. As Digital Transformation Manager, I am responsible for the digitization and automation of production-related processes within the company. My responsibilities include establishing a robust AI infrastructure and overseeing the company’s own AI use cases.
The goal of the project was to pre-populate recurring documentation templates with a changing set of data. The requirements included flexible templates, various input types, and a variable layout—all within the constraints of an air-gapped infrastructure.
The service provider submitted a compelling proposal for an AI MVP in response to our request for proposals. This allowed us to test our idea cost-effectively, and we subsequently moved directly into further developing the MVP as part of a larger project.
The collaboration involves daily check-ins to discuss project progress, test results, and requirements for further development. Applications are released for further testing in iterative cycles.
On our end, we have a product owner, IT specialists, and users from the business unit. On the service provider’s side, we are supported by a project manager and developers.
Depending on the project, we can sometimes achieve double-digit percentage savings by replacing manual searches for values with the review of pre-filled templates.
The service provider responded very flexibly to frequently changing requirements and also helped us establish a predictable requirements management process.
When developing the software, the provider doesn't just do the bare minimum—they're always willing to go the extra mile. Automated testing, UX enhancements, and suggestions for improvement are rarely seen on this scale.
Our collaboration with the service provider has been more than satisfactory in every respect. The quality and speed of the results speak for themselves.
