Ingenieur, CISSP, CEH, Security Expert / Professional Pentester
In the last years I did more than 100 Penetration-Tests and Security Assessments. Most of them on Web and Mobile applications with Finance Background implemented with various technologies and frameworks. (J2EE, ASP, PHP). Based on my daily work I am experienced with all common attack vectors and mitigation techniques. Since 2009 I am CISSP (Certified Information Systems Security Professional) and since 2017 I am CEH (Certified Ethical Hacker) certified. Please check also my UPWORK work history and client feedbacks. I am offering professional Black and Grey-box Penetration tests for Web and Mobile Applications. Sorry, I am not able to locate your girlfriend, recover your lost FACEBOOK, GMAIL, YAHOO etc. account or find your lost phone. Please do not invite me to such jobs. Before I start offensive tests, I may ask you for evidence that you are the site owner or to show me that you have admin access.
