My professional journey in the field of information security can be described as exciting and multifaceted. During my time at a major telecommunications company, I found myself at the very core of information systems, responsible for their protection and efficient management.

For 11 months, I successfully held the position of an Information Security Systems Administrator, where my responsibilities included the implementation and support of diverse systems. Through effective teamwork and my ability to quickly respond to challenges, we managed to ensure a reliable level of information protection for the company.

Upon completing the first stage of my career, I assumed the role of a Senior Information Security Systems Administrator, overseeing critical projects and facilitating the proper development of information security infrastructure. Over the course of 8 months in this role, I further strengthened my knowledge and skills.

My experience encompasses a range of contemporary information security systems, including One Identity Safeguard Privileged Access Management (PAM), Palo Alto NGFW, Tufin (Network Security Policy Management), and Picus (Security Validation Platform). I also successfully administered NGFW Checkpoint, Microsoft DLP, Cortex XDR, and piloted CrowdStrike Identity Protection.

My abilities span a wide spectrum of tools and technologies, from Cisco Firepower and Microsoft Defender to Microsoft Identity Manager, ArcSight ESM, Cloudflare, and Active Directory. Through in-depth analysis of IPS policies on Cisco Firepower, my professional insights made a significant contribution to enhancing the company's infrastructure protection.

I remain open to learning and personal development, continuously honing my knowledge and skills to stay at the forefront of the information security field.
