We entrusted François with the task of performing a penetration test on our platform. The work was rigorous and methodical, with a very comprehensive audit report, clearly prioritized vulnerabilities, and actionable recommendations. Communication was smooth from start to finish, and deadlines were perfectly met. A true professional, both technically sharp and pleasant to interact with. I recommend him without hesitation.

François was able to carry out our Pen test campaign within a very short timeframe, in line with commitments and with a significant level of detail. The quality of his reporting is very good (as good as a large firm's reporting, if not better). I highly recommend him!
