We had some very fruitful discussions with Alexandre, who was kind enough to share his experience with us.

4 / 5
The course content is dense and difficult to cover in four days. It is useful to be aware of the different types of attack. Perhaps the course lacks guidance on best practice for securing network equipment and systems.
