QSIT | IT Quality Assurance

Your specialist in strategic IT quality assurance from Ingolstadt. We provide consultancy and advice throughout the entire software lifecycle and offer a broad spectrum of services in the field of software testing and quality assurance.

Quality by QSIT

Quality is our passion – in more ways than one. As an IT quality assurance provider, our most important job is to examine whether our clients’ software meets their requirements. To avoid errors in doing that job, we must also work to the very highest quality standards in our own methods and processes. In the first instance, a carefully devised and sophisticated internal training system ensures that all QSIT employees are equipped with sound technical expertise. Moreover, our customer-focused organizational structure and values-based corporate culture makes us extremely agile and enables our specialists to give their best for quality assurance, software testing and IT security every single day.


Your Partner for Software Testing and IT Security

Your Partner for Software Testing and IT Security

We are specialists in strategic quality assurance for IT. From our headquarters in Ingolstadt and our regional office in Muscat (Oman), we support companies from sectors such as the automotive industry, finance
and retail through the entire software lifecycle and in all aspects of software testing and cyber security. Our core competences are individual test services tailormade to client needs, specializing in test automation as well as load testing and performance testing . QSIT pairs technical expertise with expert consultancy and assists companies on their journey into the digitalization of IT quality assurance. We are agile and effective in the support we provide to our clients – in crises and emergencies, too, with the “QSIT Fire Service” on standby at all times.



QSIT was founded in Ingolstadt in 2013 by Dr. Henry Guzmán. The opening of its first regional office followed in 2019 in Oman. QSIT has a dedicated team of around 50 advisers and ISTQB-certified QA specialists as well as a portfolio of targeted testing services. This means QSIT can help minimize risk, shorten development cycles and establish key competitive advantages for its clients in the field of digitalization. It all adds up to Quality by QSIT.

  • Agile – the way we think and act enables us to provide fast and effective support to our clients
  • Personal – we love data and facts as well as good relationships with our employees, clients and business partners
  • Connected – our extensive network enables a holistic approach to client support


As specialists in software testing and IT security, our commitment, confidentiality, and efficiency contribute to the success of our clients’ businesses. Our ISTQB-certified colleagues deliver individual, carefully considered solutions for your software quality, tailored specifically to your needs. Since 2013, we have assisted our clients in more than 1,200 IT quality assurance projects – a large proportion of those in the automotive industry. However, we also have experience in many other crucial sectors, such as retail, the banking sector, logistics and telecoms.

“Quality by QSIT” is enabled by a team of wide-ranging personalities. Alongside solid technical qualifications, QSIT places great emphasis on diversity. We are convinced that the more diverse a team is in respect of gender, expertise, life experience and cultural background, the better it is at dealing with change, at playing an active role in shaping the digital transformation and at handling the complexities of modern working life. Diversity is how we smooth the path to success – for our company and for our clients.
To secure the desired level of performance from your IT applications, we have developed a dedicated mobile load testing lab. This all-in-one package incorporates the mobile testing infrastructure for an individual load test, supported by experienced specialists in conceiving and implementing the tests. The mobile load test lab is quick to set up and fully adaptable to specific requirements. Plus, it doesn’t incur any of the usual licensing costs.


As experienced specialists in IT quality assurance and software testing, we’re well known not only for successfully handling long-term client projects, but also for stepping in to assist quickly and flexibly in the event of an emergency – for instance, if unexpected problems arise, threatening disruption shortly before a software launch. The QSIT Fire Service is on standby 24/7 to resolve urgent problems that could have far-reaching consequences for our client’s business.
The QSIT Academy prepares your staff for software testing – on-site at your location or at our training facility in Ingolstadt. We use specifically tailored training programs to pass on our expertise to your company. Furthermore, we use dedicated workshops to provide our own personnel with continuous development on a technical and personal level to enable them to meet our exacting quality standards day in, day out.
