I am a French Security researcher. I worked as a developer for couple of years and then decided to create the Sevagas information Security blog in 2009 during a 35000 km (9 months) trip all around Australia :-). The goal was to publish tutorials, articles, and tools.

I founded in 2016 SEVAGAS Information Security to offer to my customers the results of my researches and experience in cybersecurity.

My previous assignments were to work as CyberSecurity Expert and Business coordinator and earlier security architect in energy field (SCADA and control systems). I also worked as consultant on subjects like code auditing, payment applications and PCI-DSS environment.
