Md Sefat A.

I have over 6 years of hands-on experience in Offensive Security, penetration testing, and roles within Security Operations and DevSecOps. I possess a strong technical foundation across operating systems, networking, web technologies, scripting and active directory (AD), and I am passionate about growing into full-scale Red and Purple Teaming. I am proficient with key offensive security tools like Burp Suite, Kali Linux, and command and control C2 frameworks. My expertise includes a deep understanding of MITRE ATT&CK and OWASP testing frameworks, combined with a security-first mindset. I also have practical exposure to cloud security on AWS, Azure, GCP and On-Premises Environments, enabling me to identify misconfigurations and assess the security posture of SaaS and PaaS platforms. I work collaboratively with developers, testers, and security teams to enhance defenses, and I communicate clearly and professionally both in writing and verbally. I hold reputable security certifications, including OSCP, OSCP+ and CRTO (Ongoing) which validate my skills and dedication to the cybersecurity field.
