Nader Chelly

I hold a master's degree in cybersecurity which allowed me to be introduced to offensive security as well as cryptography. I had the opportunity to gain experience as an offensive security auditor at Devoteam, which allowed me to immerse myself in a methodology for conducting web pentests and writing reports detailing identified vulnerabilities while providing recommendations.

This summer, I obtained the Palo Alto PCCET certification and have experience in firewall administration, having been part of the network department at the University of Cergy. This experience allowed me to learn how to respond effectively to flow opening requests, particularly through the implementation of command-line generation scripts. In addition to this, I also conducted an audit of filtering rules to highlight rules with inconsistencies or security flaws.

I also have experience in network incident management, which introduced me to the methodology for diagnosing blocking points and working in environments such as Juniper, Cisco, Alcatel, Dell, and Aruba. On the system side, I have knowledge of Linux and Windows Active Directory. My support experience has enabled me to learn how to manage user incidents and enrich myself, particularly on a human level.
