Back to original languageAbout Florian
I specialize in offensive security, as an ethical hacker, after obtaining my Master's degree in 2015 from a prestigious university, I then founded Hackmosphere in 2018, after working at Deloitte, Orange and Airbus.
I perform penetration tests on Active Directory, ICS and various types of infrastructure environments. I can also carry out phishing campaigns and cybersecurity training (via a fun in-house escape game and hacking training).

The delivered report, accompanied by a particularly well-constructed executive summary, allowed our management to quickly grasp the technical issues. The responsiveness throughout the mission was exemplary, and the identified vulnerabilities - totally unknown to our internal teams - revealed critical blind spots in our scope. A serious and valuable service.
