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
Greenbone at a glance
Greenbone is a vulnerability management platform for discovering, assessing and prioritizing security weaknesses across networks, systems and applications. Its ecosystem is commonly associated with Greenbone Security Manager, Greenbone Enterprise Appliance and the open-source Greenbone Vulnerability Management stack, formerly known through OpenVAS.
Core security work
Greenbone specialists design recurring scans, authenticated assessments and remediation workflows. They help teams turn technical findings into prioritized actions by considering asset importance, exposure, severity and business context. The work can cover infrastructure, cloud-connected systems, endpoints and selected application layers.
Ecosystem and tooling
The platform combines scanners, vulnerability tests, feeds, management services and web interfaces. Strong expertise may include GVM configuration, OpenVAS compatibility, feed synchronization, certificate handling, credentialed scanning and reporting. Professionals also connect results with ticketing, SIEM and broader security operations processes.
When companies need help
- A new Greenbone environment needs secure installation and tuning
- Scan performance, credentials or feed updates are unreliable
- Findings require clearer ownership and remediation tracking
- Security teams need repeatable assessments across hybrid infrastructure
Freelance expertise is useful during deployment, migration, audit preparation and periods of changing infrastructure. In Germany, specialists may work remotely with security teams or join on-site sessions for sensitive environments and operational handover.
Skills that matter
A strong professional understands network protocols, operating systems, common vulnerability patterns and secure configuration. Useful adjacent skills include Linux, Windows, containers, cloud infrastructure, Python or shell automation, SIEM integration and security reporting. Familiarity with vulnerability scoring and risk-based prioritization improves the value of scan results.
What quality looks like
Good Greenbone work starts with a clear asset inventory and a defined assessment goal. Specialists validate credentials, scope, exclusions, feed status and scanner capacity before treating findings as reliable. They explain false positives, document decisions and provide practical remediation guidance rather than delivering an unfiltered report. Clear communication in English and, where needed, German supports collaboration with local security, infrastructure and compliance teams.
Frequently asked questions
Need clarity? These are the questions we hear most often about Greenbone.
Greenbone is used to discover vulnerabilities in networks, hosts, services and selected applications. Teams use its scans, findings and reports to prioritize remediation and track security exposure over time.
OpenVAS is the name many people associate with the open-source scanning technology within the wider Greenbone ecosystem. Greenbone can refer to the commercial products, services and managed components built around Greenbone Vulnerability Management, so the exact scope should be clarified before a project begins.
A strong Greenbone specialist should understand network security, Linux, Windows, authentication, vulnerability scoring and remediation workflows. Experience with SIEM tools, ticketing systems, cloud infrastructure and scripting is useful when scan results must feed existing operations.
The right level depends on the scope. A basic scan setup needs careful configuration and validation, while a large environment may require experience with feed management, scanner performance, authenticated assessments, segmentation and reporting. Ask for evidence of comparable environments rather than relying on generic security claims.
Greenbone work can often be performed remotely when secure access, asset information and a clear change process are available. On-site collaboration in Germany can still help with restricted networks, sensitive systems, architecture workshops and operational handover.
Look for a professional who defines scan scope, validates credentials and checks feed health before interpreting results. High-quality work distinguishes confirmed findings from false positives, explains risk in business terms and leaves documented remediation steps that security and infrastructure teams can follow.
Greenbone provides repeatable vulnerability assessment and monitoring, but it does not replace a targeted penetration test. Scanning identifies known weaknesses at scale, while penetration testing explores attack paths, business logic and chained impacts that automated checks may not establish.
A Greenbone assignment may involve appliance configuration, GVM services, scanner tuning, feed synchronization, credentials, reports or integrations. Freelancers should clarify network access, asset ownership, maintenance windows, data handling, expected deliverables and whether the client uses commercial Greenbone components or an open-source OpenVAS-based setup.
