    Hi, my name is Martin and I've been a principal penetration tester since 2011. Over the years, I've worked on a range of projects across Europe, East Asia, the Middle East, and the UK, serving clients from start-ups to global high street names. My focus is on providing a wide range of penetration testing services, including infrastructure, web and mobile applications, APIs, and cloud security assessments. One of the things that sets me apart from other penetration testers is my approach to the work. I've spent years mastering my craft, staying up-to-date with the latest technologies and techniques, and honing my skills. When I take on a project, I bring all of this knowledge and experience to bear, quickly identifying and exploiting vulnerabilities to provide my clients with the information they need to improve their security posture. In addition to my technical expertise, I'm also an excellent communicator. I understand that many of my clients are not technical experts themselves, so I'm always happy to explain complex technical concepts in simple, easy-to-understand language. I work closely with my clients to understand their needs and provide tailored solutions that meet their specific requirements. When it comes to deliverables, I take great pride in producing detailed reports and other materials that provide clear, concise information about the results of my testing. I know that my clients rely on this information to make important decisions about their security, so I always ensure that my reports are accurate, thorough, and actionable. Overall, I'm proud of the work I do as a principal penetration tester, and I'm committed to helping my clients stay safe and secure in an increasingly complex digital landscape. If you need infrastructure testing, web and mobile application testing, or cloud security assessments, please don't hesitate to get in touch – I'd be happy to discuss how I can help.

    Having spent around 7 years working in the IT industry I am a skilled security analyst capable of assessing even the most complex of web applications, networks and mobile applications. I've done penetration tests for multiple fortune 500 companies and during my time working at NorthState Technology Solutions' security consulting branch. I spent 2 years on Nike's internal penetration testing team and ended up becoming the lead of the Red Team and Purple Team program that was in-development. Lastly I built my own companies The Pentesters and ATL Tech Labs so I have a unique perspective that gives me insights as to what a business owner's objectives are as well as what the security analyst's objectives are and how to make those align. I am an OSCE (Offensive Security Certified Expert), OSCP (Offensive Security Certified Professional), eMAPT (eLearnSecurity Mobile Application Penetration Tester) and OSWP (Offensive Security Wireless Professional) so you know before you even see my work that I am qualified and able to simulate an attacker using the most up-to-date and bleeding edge tactics/techniques. During my free time I present to the Kennesaw State University Information Security Club, I work on bug bounty programs, capture-the-flag hacking competitions and personal security research projects. All in all I believe that my education, my experience and dedication to the field make me a prime candidate for all security analysis work.
