@aleksandarbojovic
Cybersecurity analyst specializing in threat detection, incident response, and security operations.
I am a hands-on cybersecurity analyst with practical experience in threat detection, incident response, and security operations, currently supporting diverse clients from my base in Belgrade. I have worked with NGFWs, EDR/XDR solutions and SIEM platforms to monitor and remediate security events.
In my role at NovaDefense I conduct incident analysis and response for a varied client base, manage endpoints and identities with Microsoft Entra ID and Intune, and fine-tune custom detection rules and threat-hunting queries to improve visibility and response capabilities. I also participate in security posture assessments and SIEM log integrations, and provide Layer 2 technical support and vendor feedback to improve product delivery.
I graduated with a BSc in Information Technology as top of my class and hold Palo Alto Networks training (PSE - Cortex Professional). I seek to apply my technical skills in a proactive security team focused on continuous improvement and strong operational defenses.
