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
Web app protection
Web application security, often called AppSec, focuses on protecting sites, portals, and browser-based products from attacks. It covers the full stack around login, input handling, data access, and session control. Strong experts help teams ship safer web software without slowing delivery.
Common work
- Threat modeling for new features and user flows
- Security reviews of authentication, authorization, and session logic
- Testing for OWASP Top 10 issues such as injection and broken access control
- API security checks for modern front ends and back ends
- Secure design advice for forms, uploads, and payments
Tooling and methods
AppSec specialists work with scanners, proxy tools, code review workflows, and manual testing. They read logs, inspect headers, trace requests, and verify how an app behaves in real use. Many also know browser security, SSO, OAuth, SAML, and the OWASP testing guide.
When companies bring in help
Teams often need freelance support before a release, after a security finding, or when a product grows faster than its controls. In Germany, this is common for SaaS, e-commerce, finance, and industrial software that must protect customer data and internal systems. Remote work fits most reviews, while on-site sessions help with workshops and sensitive environments.
What strong specialists do
Good professionals do more than run tools. They explain risk in plain language, prioritize fixes, and work well with product, backend, and frontend teams. They also know how to balance secure defaults with usable flows, which matters for login, checkout, and admin areas.
What gets delivered
A freelance AppSec expert may deliver findings reports, remediation guidance, secure coding notes, test cases, and release checks. They may also help set security standards for frameworks, API gateways, content security policy, and CI pipelines. The goal is safer delivery across the whole web application lifecycle.
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 browser-based products from attacks that target login flows, forms, APIs, and user data. It helps teams find weak access control, injection paths, session issues, and unsafe integrations before release. For most companies, it is part of building and maintaining trustworthy web software.
AppSec is the common short form for application security, and in web projects it often means the same practical work as web application security. The term is broader, because it can also cover mobile, desktop, and internal software. For hiring, people usually mean the specialist who can secure web apps, APIs, and related code paths.
A Web Application Security specialist focuses on finding and fixing weaknesses in the application itself. A WAF, or web application firewall, helps block or filter attacks at the edge, but it does not replace secure code and testing. Most teams need both, with the specialist deciding what should be fixed in code and what belongs in the defense layer.
A strong Web Application Security professional should understand OWASP Top 10 risks, HTTP behavior, browser security, authentication, authorization, and secure session handling. Useful adjacent skills include API design, code review, threat modeling, and working knowledge of frameworks such as Spring, .NET, or Node.js. Clear writing matters too, because findings must be actionable for the team.
A Web Application Security project can need different depth depending on the risk and the delivery stage. A targeted review of a checkout flow or login area may only need focused expertise, while a full security assessment of a complex platform needs broader system knowledge. The key is matching the specialist to the app’s architecture and exposure.
Yes, most Web Application Security work can be done remotely from Germany because reviews, testing, and remediation support rely on access to code, environments, and documentation. On-site work can still help for workshops, sensitive systems, or teams that prefer direct collaboration. Many companies use a mixed setup and keep the main review work remote.
A strong Web Application Security freelancer gives precise findings, explains impact clearly, and shows how to reproduce and fix each issue. Look for practical experience with real web apps, not only tool output or generic checklists. Good signs include solid prioritization, awareness of business risk, and advice that developers can act on quickly.
An AppSec engagement usually ends with a report, clear remediation steps, and direct guidance for the team that owns the code. Depending on scope, you may also get test cases, secure design notes, review comments, or follow-up checks after fixes. The best deliverables make it easy to close issues and prevent them from returning.
