    I'm a Penetration Tester with experienced in Web Application, Mobile, Web Service, Network and Source Code Analyze. I have industry-leading certifications such as OSWE (Offensive Security Web Expert), OSCP, OSWP and CEH. From my point of view my penetration testing service has 3 benefits as follows. The QUALITY of my work is my first priority. The certificates I have and the hundreds of penetration tests I have done in my company are proof of this. COMMUNICATION is very important. I share the work I did during the penetration test. In addition, I report a critical finding without waiting for the final report. Finally, I think that if the REPORT is of good quality, it is very useful for the customer.
