CSNTS training course: become a technical expert for our network solutions

With this certified training, you can become the technical expert for our Stormshield Network Security firewalls in your company. You’ll become familiar with the advanced features of Stormshield Network Security products within a complex architecture. During the Certified Stormshield Network Troubleshooting and Support (CSNTS) training course, you’ll get to grips with the most advanced features of Stormshield Network Security firewalls. The aim of this course is to introduce tools and methods for collecting the information needed to examine and correct problems using Stormshield Network Security firewalls’ Command Line Interface (CLI).

The network security of your company (and other companies) will be an open book to you. This skillset is enhanced by our Stormshield CSNTS certification.

If you are an IT manager, network administrator, IT and support technician, or a candidate aiming to become a support engineer or expert trainer on our UTM products, or a Stormshield Partner: this course is for you.

However, you need to have already passed the CSNE exam.

At the heart of CSNTS training

The structure of the course includes both theory and practical exercises. Two methods are offered: in-person courses, either at Stormshield's offices or the client's offices, and online courses, including interaction with an instructor via videoconferencing and over the Airbus CyberRange platform for practical exercises.

You’ll receive course support consisting of a theoretical component, practical work (Labs) and marking. To help you put the course theory into practice, you’ll have a full technical environment at your disposal. And you’ll be able to keep your expertise current for three years by downloading updates to the course material in PDF format on our Stormshield Institute platform.

CSNTS practical information

The CSNTS training lasts 28 hours. Stormshield offers face-to-face inter-company training sessions at its Paris, Lille and Lyon premises, or via distance learning.

Our trainers also conduct intra-company training (on-site or distance learning) for groups of 5 or more people. There is a maximum of 6 trainees per session.

CSNTS: certification at your fingertips

Provided you pass the final exam at the end of the course, obviously! You sit the exam online (3 hrs, 60 questions). The passmark is 70%. The exam is automatically available on the day following the end of training, for a period of three weeks, at the Institute’s website.

In the event of failure, or inability to take the exam within this time slot, a second and final exam opportunity automatically opens immediately afterwards for a duration of one additional week.


In common with all good software, you’ll need to update your network/security expertise before the third anniversary of your certification. You can do this using our online re-certification kits, which allow you to renew your certification for an additional three years.

As the e-learning, these re-certification kits are not considered training sessions.
