Certified Stormshield Network Expert, I am...

The Certified Stormshield Network Expert (CSNE) certification attests to the advanced features of Stormshield Network Security (SNS) firewalls. In particular, it makes it possible to evaluate the candidate's ability to configure all the features of an SNS firewall in a computer network in order to ensure the security and integrity against internal and external attacks.

This article is a continuation of the article "Certified StormShield Network Administrator, I am...".




The Certified Stormshield Network Expert (CSNE) is the highest level of Certified Stormshield Network Administrator (CSNA) certification. CSNE training and certification is only available to CSNA holders.

In the article "Cyberattack ... still alive!" was reported how we coped with a terrible cyberattack a few months ago. And that was before I was certified "Network Expert"! Now it's official: the pirates just have to stand ... Here is Verdun (*): we do not pass ;-)
