Enrique G.
Last position:
Security Architect at Capgemini
I implemented a Zero-Trust architecture for robust, military-grade maritime container mini data centers based on VMware & Tanzu to support containerized GIS workloads for ground forces. The main focus was on securing communications, workload protection, and data access in contested electronic battle environments affected by jamming, interception, signal manipulation, and constantly changing operational conditions. I designed and architected use cases so that every element of workload, identity, and system could continue to operate independently and securely even in degraded or disrupted scenarios. In parallel, I defined the enterprise and solution security architecture with LeanIX, Bizzdesign, and HOPEX as enterprise architecture, repository, and governance platforms to maintain architecture inventory, relationships, traceability, target pictures, and security governance in complex environments. For the architectural designs, I used Sparx Enterprise Architect to describe formal architecture views, interfaces, trust boundaries, and system architecture in both IT and OT environments. IriusRisk was used for threat modeling of the solution to identify architecture-driven risks, derive security requirements, and detect countermeasures and design gaps directly from the solution models. Risk and compliance management was supported with Archer. Architecture decisions, control gaps, and operational risks were translated into controlled governance and auditable compliance measures. For documentation, collaboration, and visual design, I used Confluence to maintain Architecture Decision Records, Security Blueprints, and workflows. I used Lucidchart and draw.io to create design artifacts tailored to stakeholders. I also defined OT security concepts with support from electrical and mechanical engineers in the areas of oil, vehicle onboard systems, rail, power plants, pharma, gas turbines, and nuclear technology. I created the end-to-end OT security strategy, starting with global policy, developed into standards and procedures, and finally aligned with Bell-LaPadula, Purdue Model, SABSA, TOGAF ADM, CENELEC 50701, IEC 62443, and NIST standards. In addition, I worked with engineering team leads to identify critical KBP assets and place them under protective measures that segmented SCADA, PLC, and HMI assets. I drove collaboration between Security, IT, and OT teams to create standardized workflows and use cases for the OT security solution catalog, while integrating Defense-in-Depth and Zero-Trust principles into operational environments. A key part of my work was integrating multidisciplinary engineering, security, and operations stakeholders into a unified security blueprinting strategy and ensuring that architecture, threat modeling, governance, and documentation were technically strong and operationally practical.

About the technology
Core purpose
Network Security protects data, devices, users and services as they communicate across an organisation. It combines preventive controls, continuous monitoring and incident response to reduce unauthorised access, malware, data loss and service disruption. Specialists apply these controls across offices, data centres, public clouds and industrial environments.
Security architecture
A strong design separates trust zones and limits access to what each identity, device or service requires. Common patterns include network segmentation, secure remote access, zero-trust controls, secure web gateways and resilient perimeter protection. In Germany, specialists may support organisations that must align technical controls with internal governance and sector-specific requirements.
Tools and ecosystem
Network Security work often spans several connected systems:
- Firewalls, next-generation firewalls and web application firewalls
- Intrusion detection and prevention, SIEM and security monitoring
- VPN, SD-WAN, identity-aware access and endpoint controls
- Cloud security groups, network policies and infrastructure automation
Experts need to understand routing, DNS, TLS, authentication, logging and packet analysis alongside vendor technologies from Cisco, Fortinet, Palo Alto Networks, Microsoft, AWS and other ecosystems.
Typical assignments
Companies bring in freelance specialists to deliver focused security work or strengthen an existing team:
- Assess network exposure, rules, segmentation and remote access
- Design or migrate firewalls, VPNs and cloud network controls
- Connect SIEM data and improve alert investigation workflows
- Prepare incident response procedures and contain active threats
- Test configurations, document controls and support audits
The work may cover a new cloud environment, a merger, a data-centre transition or a security improvement programme.
When to involve specialists
External expertise helps when internal teams lack capacity for a high-risk change or need an independent review. It is especially useful before a cloud migration, after a security incident, during major network redesigns or when monitoring produces too many unresolved alerts. Remote collaboration works well for analysis, design and documentation; on-site presence can matter for plant networks, hardware changes and regulated environments. Clear English is common, while German may be important for local stakeholders.
What strong professionals bring
The best specialists connect technical detail with operational risk. They can explain why a rule, route or alert matters, then implement a controlled change without weakening availability. Look for evidence of hands-on work with comparable network topologies, clear documentation, tested rollback plans and disciplined incident handling. Strong professionals also distinguish genuine threats from noise, communicate calmly during incidents and leave internal teams with maintainable processes.
Frequently asked questions
Curious about Network Security? Here are the answers that come up again and again.
Network Security is used to protect communication between users, devices, applications and services. It covers access control, segmentation, traffic inspection, monitoring, threat prevention and incident response across on-premises and cloud environments.
Network Security focuses on traffic flows, connections, network devices and access paths. Endpoint security protects individual devices, while application security addresses software design and runtime weaknesses; mature programmes combine all three areas.
A strong Network Security specialist usually understands routing, switching, DNS, TCP/IP, TLS, identity and cloud networking. Experience with SIEM, endpoint controls, scripting, infrastructure automation and incident response is also valuable.
A Network Security expert can support firewall replacement, zero-trust design, cloud migration, segmentation, VPN changes and incident response. The right level of experience depends on the environment’s complexity, business impact and the consequences of a failed change.
Ask a Network Security freelancer to explain a comparable security decision, including risks, testing and rollback. Review the clarity of their diagrams and documentation, their approach to least privilege, and how they investigate alerts without disrupting legitimate traffic.
Much of Network Security work can be done remotely, including reviews, architecture, rule analysis, monitoring and documentation. On-site collaboration may be needed for physical appliances, industrial networks or changes that require access to local facilities; language needs depend on the stakeholders involved.
Network Security projects often use firewalls from vendors such as Cisco, Fortinet or Palo Alto Networks, together with VPN, NAC, SIEM and cloud-native controls. The important skill is not memorising one product, but understanding traffic, identity, policy and telemetry across the environment.
Before starting a Network Security assignment, clarify the network boundaries, access approvals, change windows, monitoring coverage and incident escalation path. Freelancers should also confirm documentation standards, data-handling expectations and whether work involves regulated or safety-critical systems.
