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 it covers
Web Application Security protects applications, APIs and the data they process from misuse, disruption and unauthorized access. It combines secure design, defensive configuration, code review, testing and continuous monitoring across the full application lifecycle.
Where it is used
Companies rely on this discipline for customer portals, online shops, banking services, SaaS products, internal systems and public APIs. It addresses risks such as injection, broken access control, cross-site scripting, insecure authentication, exposed secrets and unsafe third-party dependencies.
- Assess web applications and APIs against common attack paths
- Validate identity, session and authorization controls
- Prioritize vulnerabilities and guide remediation
Ecosystem and tooling
The work spans application code, cloud infrastructure and delivery pipelines. Specialists may use OWASP guidance, Burp Suite, OWASP ZAP, SAST and DAST tools, dependency scanners, secret detection, web application firewalls and security information from logs and runtime monitoring. Knowledge of HTTP, TLS, browser behavior, databases and common frameworks is essential.
When companies need help
Freelance expertise is useful before a major launch, during a migration or after a security incident. It also supports teams that need an independent review, a threat model, a penetration test or a practical remediation plan without adding permanent capacity.
- Review a new product or high-risk feature before release
- Test APIs, authentication flows and business logic
- Establish security checks in CI/CD pipelines
- Investigate findings from audits or incident response
Germany projects
In Germany, specialists often support regulated industries, industrial companies, healthcare providers, finance teams and software businesses. Remote collaboration works well for code review, testing and reporting, while on-site sessions can help with workshops, architecture reviews and sensitive environments. German and English communication may both matter, depending on stakeholders.
What strong specialists deliver
Strong professionals connect exploitable findings to real business impact instead of producing a generic scanner report. They explain risk clearly, reproduce issues safely, recommend fixes that fit the stack and verify remediation. Look for evidence of work with APIs, cloud services, modern authentication, secure development practices and clear reporting for both technical and non-technical audiences.
Frequently asked questions
The facts hiring teams ask for most often when it comes to Web Application Security.
Web Application Security is used to protect web applications, APIs, user accounts and sensitive data from attacks and accidental exposure. It covers secure architecture, code and configuration reviews, penetration testing, monitoring and the remediation of vulnerabilities.
Web Application Security is a continuous discipline, while a penetration test is a focused assessment performed at a defined point in time. A strong specialist combines testing with threat modeling, secure design, development guidance, control validation and follow-up checks.
A capable Web Application Security specialist should understand HTTP, browsers, APIs, databases, authentication protocols and cloud environments. Useful adjacent skills include secure coding, threat modeling, DevSecOps, incident response, network security and familiarity with tools such as Burp Suite or OWASP ZAP.
The right level depends on the application’s architecture, exposure and risk rather than on a fixed career length. For a simple review, a specialist with focused web testing experience may be sufficient; complex systems need someone who can assess business logic, distributed services, cloud controls and remediation strategy.
Web Application Security work is often suitable for remote collaboration because specialists can review code, access test environments and deliver findings securely online. On-site workshops may still help with threat modeling, regulated environments, incident response or discussions involving sensitive stakeholders in Germany.
A Web Application Security engagement may produce a threat model, test plan, prioritized findings, evidence of exploitability and remediation guidance. The strongest deliverables also explain business impact, assign clear ownership and include a retest or verification approach.
Assess whether the specialist can demonstrate relevant work with similar applications, APIs, identity flows and deployment environments. High-quality Web Application Security work is reproducible, risk-based, clearly written and practical for the team that must fix the issue.
Web Application Security also matters for internal portals, partner APIs, administrative interfaces and services running behind access controls. Internal systems can still expose valuable data or provide a path into wider environments, so their trust boundaries and authorization rules require careful review.
The average hourly rate of freelancers in Germany who have used Web Application Security in their recent projects is 77 €, which corresponds to a daily rate of about 613 € based on an 8-hour working day.
Of the freelancers in Germany who have used Web Application Security in their recent projects, 100% hold at least a Bachelor's degree and 71% hold at least a Master's degree.
