Cyber Defense Expert at isolutions AG

Hello reader, I am a Security Analyst specialized in Detection Engineering, with a strong focus on understanding threats end to end and how different security teams collaborate across the security lifecycle. I began my career at Deloitte as an intern, where I gained hands-on experience with social engineering techniques and learned how significantly these threats can impact a multinational organization. After completing my internship, I continued with Deloitte as a Security Analyst, working with the same client and deepening my technical and analytical skills. Later, at Getronics, I further developed my investigation capabilities and expanded my knowledge across multiple areas, including vulnerability scanning, ISO 27000 controls, basic cyber threat intelligence tasks, customer-facing activities, and the practical application of the MITRE ATT&CK framework. I also took on increasing levels of responsibility, which strengthened my overall security mindset. These experiences enabled me to move into a Detection Engineer role, where I broadened my scope within cybersecurity. In this position, I analyzed current threat behaviors and designed detection rules and alerts to identify potential exploitation attempts before they escalate. Currently, at isolutions, I am focused on building a Cloud Security Operations capability from the ground up. My work includes incident response, designing standards, defining ways of working and playbooks, and researching automation opportunities to improve security investigations and response. My main goal is to enhance SecOps efficiency without compromising investigation quality. I am fully aware that there is always room for improvement, and continuous learning is something I actively pursue. Outside of cybersecurity, I spend my free time coaching and playing basketball. This has reinforced my team-oriented mindset, whether I’m working within SecOps or on the court. Best regards, Cristian
