David O.
Last position:
Machine Learning Researcher at Pattern Recognition Lab, FAU

About the technology
Network protection
A firewall controls traffic between trusted and untrusted networks. It applies rules to allow, inspect or block connections based on addresses, ports, applications, users and content. Companies use firewalls to protect offices, data centres, cloud environments and remote access services from unauthorised traffic.
Firewall types
Traditional network firewalls filter traffic at the network boundary. Next-generation firewalls add application awareness, intrusion prevention, malware inspection and identity-based policies. Web application firewalls, or WAFs, protect websites and APIs from attacks such as injection, cross-site scripting and abusive requests.
Ecosystem and tooling
Firewall work often spans products from Palo Alto Networks, Fortinet, Cisco, Check Point and Sophos. Strong specialists also work with cloud-native controls such as AWS Network Firewall, Azure Firewall and Google Cloud firewall policies. They use central management, logging, SIEM integrations, VPN technologies and infrastructure-as-code to keep policies consistent.
- Design segmented network zones and secure trust boundaries
- Configure VPN access, NAT, routing and high availability
- Connect firewall events to monitoring and SIEM systems
- Review rules, remove risky exceptions and document changes
When companies need specialists
Companies bring in freelance firewall specialists during cloud migrations, office or data-centre changes, security upgrades and incident response. They can also help when rules have grown difficult to review, remote access needs redesigning or compliance evidence requires clearer policies. In Nuremberg, on-site workshops can complement remote configuration for organisations with local infrastructure.
Project deliverables
Typical deliverables include a target architecture, zone and traffic-flow diagrams, a documented rule base, VPN configuration, migration runbooks and test plans. Specialists may tune WAF policies, integrate identity providers, automate deployments and establish alerting for suspicious activity. They should define rollback steps before changing production traffic.
What strong professionals bring
Strong firewall professionals explain why a rule exists instead of copying a vendor template. They combine packet analysis with practical knowledge of routing, DNS, TLS, Linux or Windows systems, cloud networking and identity management. They test least-privilege policies, separate administrative access, review logs and communicate clearly with security, infrastructure and application teams.
Frequently asked questions
Everything clients usually want to know about Firewall, in one place.
A firewall controls network traffic and separates systems with different trust levels. Companies use it to enforce access policies, protect internet-facing services, secure remote access and monitor connections between offices, data centres, cloud networks and applications.
A next-generation firewall combines basic network filtering with application identification, intrusion prevention, malware inspection and user-aware policies. A traditional firewall may be sufficient for simple segmentation, while more complex environments often need deeper inspection and central policy management.
A WAF protects web applications and APIs at the HTTP layer, where it can inspect requests and block attacks such as injection or cross-site scripting. A network firewall protects broader traffic flows, so many public applications need both controls rather than one replacement for the other.
A firewall specialist should understand routing, DNS, VPNs, TLS, identity and network segmentation. Cloud networking, SIEM integration, automation, incident response and familiarity with Linux or Windows systems are also valuable for projects that span the full infrastructure.
The right level depends on the risk and scope of the work. A firewall professional handling a production migration, complex segmentation or incident response should have proven experience with comparable environments, change control and rollback planning, not just product-specific training.
Much firewall work can be done remotely through secure administration, documented access and scheduled change windows. On-site collaboration in Nuremberg can still help with physical appliances, local network discovery, workshops or organisations that require hands-on coordination.
A firewall professional should provide clear traffic-flow diagrams, documented rules, test evidence and a rollback plan. Ask how they handle least privilege, logging, rule review, high availability and emergency access, then check whether they can explain security trade-offs in plain language.
A firewall specialist may work with Palo Alto Networks, Fortinet, Cisco, Check Point or Sophos, alongside cloud controls from AWS, Azure or Google Cloud. The best fit depends on existing infrastructure, traffic patterns, operational skills, security requirements and the need for central management.
