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
Core use
Encryption protects data so only authorised specialists and systems can read it. It is used for files, databases, backups, messages, API traffic, and device storage. Strong work here balances security, performance, and how the business actually moves data.
Common methods
- Symmetric encryption for fast protection of data at rest
- Public key encryption and digital certificates for secure exchange
- TLS and HTTPS for traffic between services and users
- Disk, file, and database encryption for operational systems
These methods often appear together in one architecture.
Tooling
Encryption work usually touches OpenSSL, GnuPG, PKI, HSMs, cloud key services, and framework libraries. Experienced professionals know how to integrate keys, certificates, rotation, and access controls without breaking production flows. They also document what is encrypted, where keys live, and who can use them.
When to hire
Companies bring in freelance specialists when security reviews uncover weak key handling, legacy protocols, or unclear trust boundaries. It also helps during cloud migrations, new application launches, compliance work, or incident response. In Hamburg, this is common in logistics, commerce, media, and connected systems that move sensitive data between teams and partners.
What strong experts do
- Design practical encryption schemes for the real data flow
- Set up certificate and key lifecycles correctly
- Review implementations for weak ciphers and unsafe defaults
- Align development, operations, and security teams
Good specialists explain trade-offs in plain language and leave systems easier to maintain.
Working model
Encryption projects often need remote analysis, but on-site sessions can help when teams must map data paths, review infrastructure, or prepare a rollout. Hamburg-based companies often want clear communication in English and sometimes German, especially when security, platform, and compliance teams work together. The best experts adapt to both code and process.
Frequently asked questions
Not sure where to start with Encryption? These answers cover the essentials.
A strong Encryption specialist helps protect data in transit, data at rest, and sensitive internal services. That can include TLS setup, certificate handling, key management, secure storage, and review of application-level cryptography. The goal is not just stronger protection, but protection that fits the system without slowing it down.
Encryption is the core method used to protect data. TLS is the protocol that uses encryption to secure network traffic, while PKI is the trust system behind certificates and keys. SSL is the older name people still use, but in modern work the real focus is usually TLS and certificate lifecycle management.
Bring in a Encryption freelancer when the work is hands-on and technical: key rotation, certificate issues, storage design, or fixing weak cryptography in a live system. A general security specialist may define policy, but encryption work often needs someone who can trace actual data flows and code paths. That matters most in platforms with many integrations or strict protection needs.
A good Encryption specialist usually also knows PKI, certificates, OpenSSL, cloud key services, access control, and secure application design. Depending on the stack, they may also work with Kubernetes secrets, database encryption, hardware security modules, and compliance documentation. Those adjacent skills help turn crypto rules into reliable production systems.
Look for someone who can explain why a design is safe, not just repeat terms from a standards document. A solid Encryption expert should be able to describe key storage, rotation, algorithm choice, threat model, and failure cases in clear language. Good signs are practical examples, careful documentation, and an approach that avoids unnecessary complexity.
Most Encryption work can be done remotely because the core tasks are reviews, implementation guidance, and secure configuration. On-site time can help when teams need to map legacy systems, review sensitive infrastructure, or coordinate with operations and security staff. For Hamburg companies, a mixed setup is often the easiest way to move quickly.
A good Encryption freelancer needs enough context to understand what data is protected, where it moves, and who must access it. They do not need every business detail, but they do need architecture diagrams, certificate inventories, key ownership, and any compliance constraints. The better the inputs, the faster they can make the system safer.
A common Encryption mistake is treating it as a checkbox instead of a system design problem. Teams often choose weak defaults, store keys badly, or add encryption without clear ownership for certificates and rotation. Another frequent issue is mixing old and new standards, which creates hidden risk and operational confusion.
