Aruba ClearPass — Independent NAC Consulting & Support Aruba ClearPass is one of the most capable Network Access Control platforms available — but its flexibility also makes it complex to implement correctly. A ClearPass deployment that works in a lab often breaks in production because of edge cases: non-802.1X devices, legacy printers, BYOD certificate failures, or guest portal redirects that do not behave as expected on mobile devices.
With 11+ years of enterprise NAC experience — deploying ClearPass alongside Aruba wireless, Cisco switching, and HP infrastructure — I provide independent consulting, deployment support, and managed services for organizations that need ClearPass expertise without a full-time specialist.
...
Cisco ISE & 802.1X NAC — Independent Consulting & Support Network Access Control is one of the most complex areas of enterprise security — and one of the most frequently misimplemented. Cisco ISE projects fail not because of the technology, but because of what surrounds it: Active Directory structure, PKI design, certificate lifecycle, VLAN architecture, and endpoint posture policies that have to survive real users, real devices, and real helpdesk pressure.
...
Cisco Collaboration Support & Managed Services Your Cisco Collaboration infrastructure runs your business communication — IP phones, video conferencing, Jabber, Webex. When it breaks, work stops. When it’s poorly managed, it becomes a hidden cost center.
With 10+ years of hands-on experience across dozens of Cisco Collaboration deployments — banking, manufacturing, aviation, petrochemical — I provide remote managed services, support, and new installations for organizations that need a specialist without the cost of a full-time engineer.
...
Enterprise WiFi & Network Design Poor wireless coverage, network bottlenecks, and ad-hoc infrastructure decisions accumulate into real business problems — dropped video calls, slow file transfers, security gaps, and projects that fail at go-live.
With 11+ years of enterprise network and wireless experience — designing and deploying Cisco and Aruba environments across hotels, factories, campuses, warehouses, and corporate offices — I provide network design, wireless planning, and infrastructure project delivery for organizations that need it done right.
...
Firewall Management & Security Audit Services Your firewall is your first line of defense — but only if it’s properly configured and actively maintained. Bloated rule sets, outdated firmware, misconfigured VPN tunnels, and unmonitored open ports are silent risks that accumulate over time.
With 11+ years of enterprise firewall experience across banking, manufacturing, and critical infrastructure — managing 100+ physical and virtual firewalls simultaneously — I provide remote firewall management, optimization, and security audits for organizations that need a specialist without the overhead of a full-time engineer.

Network Security & Infrastructure Consulting for Enterprises In today’s complex threat landscape, your network infrastructure must do more than just “work”—it must be resilient, transparent, and secure.

Based in Munich, I bring expertise from high-security sectors like banking and industry directly to your business.
