Last position:
Project Manager (Enterprise Cloud Governance) at CompuGroup Medical SE & Co. KGaA
Short description: Leading a group-wide project to establish standardized cloud governance for Microsoft Azure, including policies, security and compliance controls, automation, and cost and operations management while preserving the autonomy of decentralized business units within regulatory frameworks.
Tasks and activities:
Overall responsibility for designing, building, and implementing a company-wide cloud governance structure (Azure), including target picture, roadmap, and operating model.
Managing internal and external stakeholders (C-level, IT, Security, Compliance, Cloud Architecture, DevOps), including decision and escalation management.
Planning and facilitating workshops on cloud strategy, governance principles, and the design of areas such as identity, connectivity, and platform management.
Defining, implementing, and rolling out cloud policies (Azure Policy / custom policies), security standards, and compliance requirements (including GDPR, ISO 27001, BSI C5).
Building a cloud governance framework based on the Azure Cloud Adoption Framework (CAF), including landing zone and guardrail concepts.
Introducing automation solutions for governance, security, and cost control (policy/control automation, IaC, CI/CD-based control mechanisms).
Implementing cloud security and compliance monitoring mechanisms as well as continuous improvement processes.
Establishing and operationalizing FinOps in an enterprise environment (central and decentralized FinOps teams), including cost management strategies, reporting, and guardrails.

Enrique Gallardo
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
Risk view
Threat modeling is a structured way to find how a system can be attacked before it goes live. It helps teams spot trust boundaries, weak flows, and missing controls in web apps, APIs, cloud services, and embedded systems.
Common methods
- STRIDE for threats by category
- Attack trees for paths and abuse cases
- Data-flow diagrams for system views
- PASTA for risk-driven analysis
Good specialists choose a method that fits the project, then translate the result into action. They can work with security, product, and architecture teams without turning the exercise into theory.
Where it fits
Companies bring in freelance threat modeling experts when a new design needs review, a legacy platform needs a fresh risk pass, or a security gap blocks launch. In Germany, this often sits alongside cloud migration, fintech work, industrial software, and B2B platforms with strict customer demands.
What strong experts do
A strong professional does more than list threats. They ask how data moves, where identity is checked, what happens if a control fails, and which abuse cases matter most.
- Review architecture and data flows
- Facilitate workshops and capture decisions
- Rank risks and suggest mitigations
- Write clear outputs for engineering teams
Skills around it
Threat modeling specialists usually know secure design, application security, IAM, network trust zones, and common cloud patterns. They also need clear writing, sharp questioning, and the discipline to keep findings specific enough to act on.
Delivery and outputs
Typical deliverables include a threat model, a risk list, mitigation notes, and follow-up actions for owners. Good work also captures assumptions, open questions, and places where controls depend on other teams or vendors.
Frequently asked questions
Questions about Threat Modeling? Start with the answers below.
Threat Modeling is used to find where a system can be abused before attackers do. It helps teams review design choices, data flows, identity checks, and trust boundaries, then turn the findings into concrete mitigations.
Threat Modeling is the wider practice; STRIDE is one common method inside it. Teams often use STRIDE to organize threats, but they may also use attack trees, data-flow diagrams, or a mix of methods when the system is more complex.
A company usually brings in a threat modeling specialist when a new product design, major change, or security review needs a clear risk view. It is especially useful when teams must align product, architecture, and security quickly without guessing.
A strong threat modeling professional usually understands secure architecture, application security, IAM, cloud setups, and how systems fail in practice. Clear facilitation matters too, because the work often happens in workshops with mixed technical and business teams.
Threat Modeling is done before or during design to prevent issues; penetration testing looks for weaknesses in a built system. They complement each other, but they solve different problems and answer different questions.
A small system review may only need one experienced threat modeling expert who can run a focused workshop and write a crisp output. Larger programs often need someone who can handle multiple services, shared components, and longer decision chains across teams.
Yes, Threat Modeling works well remotely when the expert can access architecture notes, diagrams, and the right stakeholders. In Germany, many teams still like a short on-site workshop at the start, then continue the follow-up remotely in English or German.
A good Threat Modeling deliverable is specific, readable, and tied to the real system rather than generic threat lists. It should show assumptions, priority risks, practical mitigations, and clear next steps that engineering teams can use right away.
The average hourly rate of freelancers in Germany who have used Threat Modeling in their recent projects is 108 €, which corresponds to a daily rate of about 868 € based on an 8-hour working day.
