Information Security & GRC Expert at GLG (Gerson Lehrman Group)
As a Council Member at GLG (Gerson Lehrman Group), the world’s leading expert network, I provide organizations, investment firms, and consulting companies with expert discussions on demand – wherever specialized knowledge in information security, IT governance, and regulatory compliance is needed.
My assessments are based on many years of practical experience in highly regulated industries: from building and implementing information security management systems (ISMS according to ISO 27001), IT risk and vulnerability management, and business continuity (ISO 22301) to the practical implementation of European regulations such as DORA, NIS2, BAIT, and the Cyber Resilience Act (CRA).
The cooperation is project- and discussion-based. I provide decision-makers with a practical perspective gained from real-world experience on cyber risks, security governance, and operational resilience – exactly when it is needed.

About the technology
What WAN covers
WAN, or wide area network, connects offices, data centres, cloud environments and remote sites across different locations. It uses carrier circuits, internet links, VPNs and routing services to move business traffic securely beyond a local network. A well-designed WAN balances availability, performance, security and operational control.
Where it is used
Companies rely on WAN connectivity for distributed operations, shared applications and access to central services. Common assignments include:
- Connecting branches, warehouses and headquarters
- Linking private data centres with public cloud environments
- Supporting voice, video and business-critical applications
- Providing secure access for remote and mobile teams
- Replacing rigid private circuits with flexible internet-based paths
Ecosystem and tooling
WAN work spans routing protocols, firewalls, VPN technologies, network monitoring and identity controls. Specialists may work with MPLS, SD-WAN, IPsec, BGP, OSPF, QoS and zero-trust access patterns. Vendor environments can include Cisco, Fortinet, Palo Alto Networks, VMware, HPE Aruba and cloud-native networking services.
When companies need specialists
Freelance expertise is useful during network redesigns, site rollouts, migrations and incident-heavy periods. Companies may need an impartial review of carrier contracts, routing behaviour or security controls before committing to a target architecture. In Hamburg, distributed logistics, manufacturing, commerce and media operations can benefit from professionals who understand both local site realities and remote collaboration.
What strong professionals deliver
Good WAN specialists translate application needs into practical connectivity and failover decisions. They document topology, address plans, routing intent, security boundaries and operational procedures clearly. They also test failure scenarios, measure application impact and leave teams with usable dashboards, runbooks and escalation paths.
Choosing the right expertise
Look for evidence of comparable multi-site environments, careful change planning and hands-on troubleshooting. Relevant adjacent skills include LAN and Wi-Fi design, firewall policy, cloud networking, DNS, identity management and observability. For on-site work in Hamburg, clarify language expectations, access requirements and the split between field activity and remote configuration before the engagement begins.
Frequently asked questions
Key details about WAN, drawn from the questions we get asked most.
A WAN connects offices, branches, data centres, cloud services and remote locations over geographically separated links. Companies use it for application access, voice and video, shared systems, secure remote work and traffic between business sites.
A WAN connects sites across distance, while a LAN serves a local building or campus. SD-WAN is an approach to managing WAN paths through central policy, application awareness and automated use of links such as private circuits and broadband; it is not a separate replacement for all underlying connectivity.
A strong WAN professional often also understands routing, firewalls, VPNs, DNS, identity controls, cloud networking and monitoring. Familiarity with BGP, OSPF, QoS, IPsec and vendor platforms helps when connectivity, security and application performance must be solved together.
A WAN freelancer should show hands-on work with environments comparable in scale, criticality and geographic spread to your own. Ask for examples of migrations, failover testing, incident resolution and documentation, then assess whether the person can explain trade-offs in terms your stakeholders understand.
Much of WAN design, monitoring, configuration and documentation can be completed remotely when secure access and reliable site contacts are available. Physical circuit handovers, cabling checks and equipment replacement may require local support, so agree on the on-site and remote split early.
For a WAN engagement in Hamburg, clarify which sites need visits, which systems are in scope and whether communication should be in German, English or both. Also align on maintenance windows, carrier coordination, access approvals and the handover expected after each change.
Review the WAN specialist's topology diagrams, change plans, test evidence and incident records. Quality shows in clear failure scenarios, least-privilege security, measurable acceptance criteria and documentation that another professional can operate without relying on informal knowledge.
A WAN based on SD-WAN can suit organisations that use multiple link types, cloud applications and changing traffic policies across many sites. Traditional private connectivity may still fit stable, predictable workloads, so the decision should consider resilience, security, application behaviour, carrier options and operational capability rather than the label alone.
