Network and cybersecurity engineer with 5 years of experience, I have acquired solid expertise through various projects involving technologies such as Palo Alto, Fortinet, Checkpoint, Wallix, Zscaler, Active Directory, PKI, Okta, SentinelOne, Tufin, and Splunk.
This diversity of tools and contexts has allowed me to develop a global and operational vision of IT security challenges, both in terms of network, identity, and incident detection and response.
