🛡️ Why not hire an ethical hacker to secure your digital assets?
Stop attacks before the CFO hears about them.
According to Forbes¹,every minuteof downtime costs large companies≈ €9,000**. My mission for the past **8 years**: to reduce that cost. My 360° support - external, internal, AD, Wi-Fi pentesting, project management - has strengthened the security posture of over **50 companies**, limiting financial impact to **a few minutesrather than several hours.
Certified **OSCP & CRTP**, I go from the executive committee to the root shell without a translator: pedagogical and clear communication for decision-makers, actionable remediation from day 1 for your CISOs and security teams.
WithStealed.io**, my credential leak monitoring tool, your access is **protectedbefore it's even monetized. Avoid the next CNIL report;test itnow ➡️ https[:]//app[.]stealed[.]io/
Choose your next challenge:
- Free Flash Audit – 1/2 day:Express mapping of your attack surface.
- Credential Hygiene:No valid access detected in 14 days?-20%on contracting.
Every day without visibility adds to the cybercrime budget. Reduce yourMTTD/MTTRand regain control.
