Antonin Tessier

Passionate IT security expert, I have studied, implemented, and managed various market-leading solutions:

* Palo Alto firewalls: TLS and SSH decryption, IDS/IPS, URL Filtering, antivirus, etc.

* Fortinet firewalls: replacement of old firewalls with IPS and anti-DDOS implementation.

* Cisco ISE: implementation of 802.1X access control (wired + Wifi) with dynamic VLAN assignment; compliance verification (antivirus running, disk encrypted...).

* Okta: identity management and MFA (SAML2, OpenID).

* Mail flows: DMARC, DKIM, and SPF implementation.

* Implementation of Fortinet load balancers to address the dual ISP requirement.

* Network management: static and dynamic routing.

* Rapid7: vulnerability analysis/monitoring of the existing IT infrastructure.

* Innovative tools: Darktrace and Tenable for real-time monitoring of Active Directory and the network.

From a governance perspective in my role as CISO, I participated in the security accreditation of a system for a state client. To achieve this, I coordinated actions (PASSI audits, risk analysis, BCP/DRP, compliance plan, and ISMS).

Having supervised an apprentice for 3 years, I am committed to sharing my knowledge and continuous learning.

Certified Cisco CCNP Security, I will continue by pursuing the CISSP certification.
