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
Encryption protects data so only approved systems and people can read it. It is used for files, databases, backups, APIs, emails, and message traffic. Strong work here fits into product security, infrastructure, and compliance tasks.
Core methods
- Symmetric encryption for fast data protection with AES and similar ciphers
- Public key cryptography for exchange, signatures, and trust with PKI
- Transport security with TLS for web, app, and service connections
- Email and file protection with PGP, GPG, and related tooling
Where it is used
Teams bring in specialists when they need secure releases, safer cloud setups, or a cleanup of weak key handling. In Hamburg, this often matters for logistics, commerce, media, and regulated service systems that move sensitive records across internal and external networks.
What strong specialists do
They choose the right scheme for the job, rotate keys safely, and avoid common mistakes like hardcoded secrets or broken certificate handling. They also test interoperability, document trust flows, and make sure encryption supports operations instead of blocking them.
Tooling and ecosystem
- OpenSSL for certificates, TLS testing, and command-line checks
- Java, Python, Go, or .NET libraries for app-level encryption
- Cloud KMS and HSM services for managed keys and hardware-backed storage
- Vault and secret stores for operational key and secret handling
When to hire freelance help
Freelance experts are useful for audits, migration work, incident follow-up, and short projects that need focused attention. They can work remote or on-site in Hamburg when teams need local coordination, but most design and implementation tasks can be handled remotely with good access and clear scope.
Frequently asked questions
Not sure where to start with Encryption? These answers cover the essentials.
Encryption turns readable data into protected data so only authorized systems can recover it. Companies use it to secure stored records, API traffic, backups, email, and mobile or desktop content. It is a core control when data moves beyond one trusted machine.
Encryption is a core method inside cryptography, but the terms are not identical. TLS uses encryption to protect traffic in transit, while PGP and GPG focus on email and file protection. A good specialist knows when each one fits and when a broader cryptographic design is needed.
A strong Encryption specialist usually also knows PKI, certificate lifecycles, secret handling, and secure key storage. App teams often need practical skill with OpenSSL, cloud KMS tools, and the language libraries used in Java, Python, Go, or .NET. Clear documentation matters as much as the code.
Encryption work can be small or deeply system-wide, so the right background depends on the task. For a certificate fix or a file-protection feature, a focused specialist may be enough. For a platform migration or key-management redesign, you need someone who understands architecture, operations, and rollout risk.
Bring in Encryption expertise when you need to replace weak custom code, review a security design, or add protection to an existing product without slowing the team. It also helps after incidents, during cloud migrations, or when internal teams need a second set of eyes on trust and key handling.
Encryption specialists often work well remotely because most design, review, and implementation tasks can be done from shared repositories and system access. On-site time in Hamburg helps when teams need workshops, sensitive environment access, or close coordination with security and infrastructure groups. Many projects use a mix of both.
A strong Encryption freelancer talks about threat models, key rotation, certificate chains, and failure cases, not just algorithms. They should explain trade-offs in plain language and show how the design fits your systems. Good specialists also test recovery paths, not only the happy path.
The biggest mistake is adding Encryption without managing keys, certificates, and access controls. Another common issue is using the right algorithm in the wrong place, or protecting data at rest while leaving interfaces exposed. Good implementation needs design, operational discipline, and review.
