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
What OWASP covers
OWASP, the Open Web Application Security Project, gives teams a shared way to find and reduce application risk. It is used to review code, test running systems, and shape secure delivery practices. The OWASP Top 10 is often the first reference point.
Typical work
- Web application security reviews
- API testing and threat analysis
- Secure design input for new features
- Vulnerability triage and remediation support
- Security checks for CI/CD and release gates
Tooling and methods
Strong professionals know how to use OWASP guidance in day-to-day work, not just in reports. They work with tools such as ZAP, threat modeling notes, secure coding checklists, and penetration testing findings. They also know how to turn weak findings into clear fixes.
When companies bring in help
Companies often look for freelance OWASP specialists when a product is going live, a security audit is due, or an internal team needs a second set of eyes. In Hamburg, this is common for software teams working with commerce, logistics, media, and regulated data. Remote work is often enough, but on-site sessions help with workshops and stakeholder reviews.
What strong specialists do
- Explain risk in plain language
- Prioritize issues by business impact
- Map findings to concrete fixes
- Work well with product, engineering, and security teams
- Document decisions in a way that supports future releases
Skills around OWASP
OWASP work often sits next to secure coding, authentication, session handling, cloud security, and API design. A strong specialist understands how vulnerabilities appear across frameworks, not just in one stack. They also know when to use OWASP Top 10, ASVS, or Testing Guide material for the task at hand.
Frequently asked questions
Key details about OWASP, drawn from the questions we get asked most.
OWASP is used to find, explain, and reduce risk in web apps and APIs. Teams use its guidance to review design choices, test for common flaws, and improve secure coding practices. The OWASP Top 10 is often the starting point, but strong work goes deeper into the full application flow.
OWASP is not a single test method. It is a set of widely used security standards, checklists, and project guidance that can support both penetration testing and code review. Companies often choose an OWASP-focused specialist when they want practical fixes, not just a list of findings.
A strong OWASP specialist usually knows secure coding, threat modeling, API security, authentication, and session handling. Knowledge of common web stacks also helps, because the risks often depend on framework behavior and deployment setup. Communication matters too, since findings must be clear to product and engineering teams.
OWASP reviews can be useful even for focused tasks, but the right level depends on the system. A small feature review may need someone who can spot common flaws and suggest fixes, while a larger platform may need broader experience across architecture, testing, and remediation. The more complex the login, data, or API flow, the more valuable senior judgment becomes.
For many OWASP tasks, remote collaboration works well. The specialist can review code, test exposed endpoints, and document risks without being on site. In Hamburg, on-site time can still help when teams want live workshops, stakeholder alignment, or faster discussions around sensitive systems.
OWASP Top 10 is a high-level view of the most common web application risk areas. ASVS, or Application Security Verification Standard, is more detailed and is better for defining security requirements and verification depth. A good specialist knows when each one fits the project.
A strong OWASP freelancer gives clear evidence, not vague warnings. Look for practical findings, good prioritization, and remediation advice that fits your stack and release process. Good specialists can explain why an issue matters, how to fix it, and how to prevent it from returning.
OWASP started with web application security, but its guidance now extends into APIs, authentication flows, and modern delivery practices. That makes it useful for many internet-facing systems, not just classic websites. The best specialists adapt the guidance to the actual architecture instead of forcing a generic checklist onto every project.
