About Christopher
Sie suchen einen Cybersecurity-Experten, der nicht nur berät, sondern auch umsetzt?
Ich bringe zusammen, was selten in einer Person vereint ist: strategische Beratungskompetenz aus der Big4-Welt (PwC) und hands-on technische Tiefe aus dem operativen Cybersecurity-Betrieb von DAX-Konzernen (Covestro/Bayer).
Was ich für Sie leisten kann:
End-to-End Cybersecurity, von der Gap-Analyse und ISMS-Beratung (ISO 27001, BSI IT-Grundschutz) bis zur operativen Umsetzung: SIEM-, SOAR- und EDR-Betrieb, Detection Engineering, Digital Forensics & Incident Response (DFIR), Malware-Analyse und Threat Intelligence.
Meine Schwerpunkte:
- CrowdStrike Falcon & Microsoft Defender Suite (Endpoint, Identity, Office 365) — Deployment, Tuning, Operations
- Cloud Security (Azure, AWS) & On-Premise-Infrastrukturen
- OT Security in industriellen Umgebungen
- Steuerung externer Dienstleister und SOC-Optimierung
- Automatisierung von Detection- und Response-Workflows
- Zertifizierungsbegleitung und Audit-Readiness
Was mich besonders macht:
Ich kann auf Augenhöhe mit CISO, IT-Leitung und SOC arbeiten, weil ich beide Welten kenne. Mein Hintergrund aus Konzern-IT, Big4-Consulting und operativer Security-Praxis sorgt dafür, dass aus Strategie konkrete, messbare Umsetzung wird.
Ideal für Projekte wie:
Aufbau & Optimierung von Security Operations, DFIR-Unterstützung, ISMS-Implementierung, Endpoint-Security-Rollouts, Cloud-Security-Assessments oder Security-Transformationsprogramme.
Lassen Sie uns sprechen, ich freue mich auf Ihre Herausforderung!
