We believe in what we say, but experience is more valuable than theory. Tell us what your needs are and give us a try. We’re confident you’ll be more than satisfied.


Certification, regardless of the standard (ARP-4754, FAR-21, CS-25, etc.), is a fundamental process involved in the development of a transport platform, which could have catastrophic consequences in the event of failure.

At CENTUM Digital, we guide you through all stages of the certification process, from conceptualisation, planning, certification requirements, verification and validation, as well as in dealings with the certification authorities. Not only do we offer you advice, we can also prepare documentation and help you to optimise timing and costs using automation tools.


Analysing the safety of systems is key to identifying risks and the associated likelihood of failure. This analysis provides a basis for determining the criticality of the systems to be developed, which will have a significant influence on the planning, the processes themselves and their design.

At CENTUM Digital, we assist you with the preparation of the associated documentation in line with the applicable standards (ARP-4761, DEF-STAN-0056, MIL-STD-882, ISO26262, etc.). We advise you on critical decisions in order to ensure safety, optimising the necessary resources depending on criticality.


The applicable standards (DO-254, DO-178, MISRA C, etc.) and certification and safety requirements determine how the software and hardware design, development and testing processes are to be executed. If this falls short of a certain standard, there may be unpleasant surprises with regard to the end user or the certification authorities, which could result in major and costly redesigns.

At CENTUM Digital, we can advise you from the outset in order to avoid such issues and/or delivery delays. We can also assist you with the preparation of documentation, the design and development of software and hardware, as well as throughout the verification and validation phase. We rely on automation tools in all phases: design, coding and testing.



When systems are integrated into a platform, there are certain environmental requirements that the equipment must meet to ensure that it can withstand hostile environments, such as salt spray, high pressures or temperatures and electromagnetic overload, as well as to prevent failures in the surrounding systems.

At CENTUM Digital, we help you to define these requirements, while taking into account the applicable standards (ECSS-Q-ST-70, MIL-STD-810, DO-160, etc.). What’s more, we devise the test plan, which we execute in certified laboratories, and prepare the relevant report.



Based on our extensive experience in electronic, communications and software engineering, we offer Industry 4.0 and connected industry projects and solutions. These help to optimise industrial processes by means of digitalisation and big data and artificial intelligence algorithms.


Automation has revolutionised testing. Working in short cycles forces us to speed up the QA process and this can’t always be achieved manually. This is why we’ve been developing specific tools and improving our methodology at Centum since 2015. We guarantee that you’ll only ever speak to genuine automation experts.


Cybersecurity should respect the principle of protecting what is truly important –with the necessary measures at an effective cost. We’ll tell you how it’s done.


New methodologies, being more agile, require us to have very short development cycles. QA must be more exhaustive than ever to assist with development and, at the same time, swift so as not to hamper the go-to-market. At Centum, we know how to address this challenge.
