High-Availability Network Infrastructure & IT Security – Consulting, Design & Implementation
Availability isn't a luxury – it's the foundation for productive business processes, secure system communication, and the protection of sensitive data. But as complexity grows, so do the demands on network design and IT security. We help you build infrastructures that don't just work, but remain resilient under load, during failures, and under attack.
Network Design & High Availability
We plan and implement network architectures designed for resilience and performance:
- Redundant Topologies – Building networks with redundant paths, Link Aggregation (LACP), Spanning Tree (RSTP/MSTP), and VRRP/HSRP for seamless failover.
- Network Segmentation – Logical separation of IT and OT networks, DMZ design, VLAN concepts, and microsegmentation to reduce attack surfaces.
- Software-Defined Networking – Leveraging SDN technologies for centralized control, automation, and rapid adaptation of network infrastructure.
- Industrial Networking – Ruggedized switches, ring topologies (MRP, HSR, PRP), and deterministic communication for industrial environments and critical infrastructure.
- WLAN & Site Connectivity – Enterprise WLAN planning, site-to-site VPN, SD-WAN, and secure connectivity for remote locations.
IT Security & Hardening
Security doesn't start at the firewall – it permeates the entire infrastructure. We consult and implement:
- Firewall & Perimeter Security – Design and configuration of next-generation firewalls, application layer filtering, and intrusion detection/prevention (IDS/IPS).
- Zero Trust Architecture – Implementing zero-trust principles with identity-based access control, Network Access Control (NAC), and least-privilege concepts.
- Encryption & Secure Communication – TLS/IPsec for all communication paths, certificate management, and PKI setup.
- Logging, Monitoring & SIEM – Centralized logging, anomaly detection, and integration into SIEM systems for continuous monitoring.
- Hardening & Compliance – System hardening according to CIS Benchmarks, BSI IT-Grundschutz, or NIS2 requirements. Vulnerability analysis and penetration testing on request.
Consulting & Audit
Already have existing infrastructure? We analyze your network for vulnerabilities, bottlenecks, and improvement potential:
- Network assessments and architecture reviews
- Security audits and gap analyses
- Documentation and network visualization
- Development of security concepts and incident response plans
Training & Knowledge Transfer
On request, we train your team in network technology, firewall administration, secure configuration, and incident response – hands-on and tailored to your environment.
Contact us – we'll analyze your infrastructure and develop a solution that combines availability and security.
