At Water IT Security & Defence GmbH, I monitor security events in Microsoft Sentinel and investigate alerts, log data, and suspicious activity to identify potential threats.
I analyze suspicious emails and URLs using Microsoft Defender and sandbox environments, and investigate sign-ins and identity activity in Microsoft Entra ID. I also contribute to developing use cases, alert rules, and playbooks.
At WISAG Dienstleistung und Holding, I administered network and security infrastructure for around 1,500 external locations. I configured Fortinet firewalls through FortiManager and monitored network and firewall data with FortiAnalyzer.
My work also included VPN connections between external locations and central infrastructure, network troubleshooting, and supporting infrastructure improvements. I hold SC-200, CCNA, and Fortinet Certified Associate in Cybersecurity certifications.
