Secure development training

Who is secure development training for?

For web application developers (frontend, backend or APIs) who want to learn the basics of security so that they can write code securely. A grasp of the basics of coding is a condition for taking this course. The course is frequently given to entire development teams that need to work on their security skills together.

Why secure development training?

More and more, ownership of software quality is coming to lie with the developers themselves. DevOps teams are making a shift left, making it essential for security to be assured right from the start of the development process.

If a lot of vulnerabilities are discovered in the software after development, this can be a further reason to improve the training of the developers. In such cases, the dependence of the testing is often too great. A large proportion of the vulnerabilities are unnecessary and can be prevented.


More secure software! Thanks to greater security awareness and knowledge on the part of the developer(s). They know the basic principles of secure programming and are familiar with potential and common risks. They have been given practical tools to prevent vulnerabilities.

Price, dates and location

The training lasts 1 day and costs 950 euros per person.

We provide a pleasant and relaxed learning environment. The courses are held at the Computest office. We have a beautiful space available for this purpose with a roof terrace, and we also serve a delicious lunch. The training is also available in-company and can also be delivered at the customer location.


This is a classical, interactive course with lots of practical examples which participants are encouraged to try their hand at themselves.
Important elements of the course:

  • Viewing pieces of vulnerable code. What is happening, why is it going wrong and how can we exploit the vulnerability?
  • The principles of secure development; what are they? What are the principles of writing secure code?
  • What are the pitfalls of some modern application technologies and frameworks?
  • Jointly hacking a large website.

Training by our hackers

The most important thing that sets our courses apart is that they are taught by our own ethical hackers with programming knowledge. Our trainers are first and foremost passionate hackers who apply their skills to complex security projects on a daily basis. And who better to train a developer than a hacker?

Thanks to the enthusiasm with which they communicate their knowledge and vividly illustrate it with examples and practical situations, they are valued as trainers and guest speakers. Our trainers work at and are educated to higher vocational/university level and are selected for their good communication and social skills.

Our vision of learning

We strongly believe in ‘learning by doing’. At Computest, about 75% of the secure development course consists of hands-on training. With the help of lots of interaction and various challenges, the participants get to work themselves. Our trainers supervise them closely during the assignments and answer questions so that they can work independently in practice.

Assuring quality

Daan Keuper is responsible for the overall quality of our training. He is a top hacker; he has finished third in global hacking competitions three times and made the news by finding vulnerabilities in the iPhone and in a passenger vehicle. He also has over 10 years of experience in delivering security and other training courses for technical and non-technical participants.

Daan develops the customised courses, provides the teaching materials and constantly keeps them up to date. He delivers courses himself and is also responsible for selecting, training and supervising other trainers. Daan regularly sits in on courses to monitor their quality and the professionalism of the trainers and to provide guidance where necessary. We also ask our participants for feedback after each course by means of an anonymous tool. This feedback is discussed by Daan and the trainers in order to further improve our courses.


Tailor-made courses are always an option, for large or small groups. Thanks to the broad knowledge we have in-house, we can provide courses for all kinds of target groups and to a very high technical standard. Courses can also be focused on a particular topic, for example mobile apps.

As such, you will always be able to find an appropriate course or have one tailored to your needs. Please contact us to discuss the options.
