ABOUT GEORGIOS SAKATZIDIS

Results-driven, highly motivated, and versatile professional who brings a strong combination of hands-on technical experience and formal education in Cybersecurity. My career began with eight years working in my family’s Car Audio and Security business, where I handled customer interactions, troubleshooting complex technical issues, and maintaining strong client relationships. This experience sharpened my problem-solving abilities and ability to manage high-pressure situations effectively. Driven by a passion for technology, I transitioned to Cybersecurity, earning a Master’s degree in Cyber Security with First Class Honors. My studies equipped me with theoretical and practical knowledge in Information Governance, Ethical Hacking, Network and Wireless Security, Risk Management, and Project Management. My thesis,\"Framework Proposal towards Penetration Testing for Internet of Medical Things,\" reflected my focus on addressing security challenges in emerging technologies. Currently, I work at SE Labs, a leading security testing and consultancy firm, where I focus on enhancing information security by evaluating security products designed to protect against modern threats. My expertise includes testing Endpoint Detection and Response and Endpoint Protection Platforms, antivirus, and email security solutions using arbitary and crafted malware. I engage in red team activities such as penetration testing and phishing campaigns to simulate real-world attack scenarios. In addition to security testing, I conduct incident response procedures by analyzing logs, detecting malware, and restoring compromised systems. My exposure to cutting-edge tools keeps me up-to-date on the latest techniques used by cybercriminals, allowing me to stay ahead of evolving threats. Through my Cisco Security certifications, I’ve developed a comprehensive skill set in networking and security. I am proficient in configuring and securing Cisco network devices, managing firewalls, VPNs, and intrusion prevention systems, and implementing identity and access management solutions using Cisco ISE, 802.1X, RADIUS, and TACACS+. My expertise extends to defending network infrastructure against MITM, DoS, VLAN hopping, and insider threats, ensuring compliance with industry security standards. Additionally, I have experience integrating advanced threat protection tools such as Cisco AMP and Umbrella, enhancing overall network resilience. Moreover, I am an active user of HackTheBox, where I completed the Penetration Tester Job Path and achieved Hacker level by solving complex security challenges.
