My approach

For me, cybersecurity is not just about installing a firewall or deploying a singular tool; It is a strategic discipline that manages business continuity, data integrity and access control together. Analyzes risks according to threat model, asset criticality level and possible impact coefficient; I apply technical measures in a layered manner according to this prioritization. Instead of temporary solutions, I establish a sustainable security standard with permanent architectural improvements, traceable log structure and regular verification tests. My goal is not only to stop the attack, but to create measurable defensive maturity that systematically prevents the recurrence of the same vulnerability.
