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
Centralized Network Device Administration
Terminal Access Controller Access-Control System Plus provides secure, centralized validation for users seeking administrative access to routers, switches, and firewalls. By separating authentication, authorization, and accounting functions into independent elements, it enables fine-grained command-level control over multi-vendor network hardware.
Core Protocol Strengths and Ecosystem Integration
The protocol encrypts the entire payload of access requests rather than just the password field, ensuring strong transport security across enterprise fabrics. Freelance specialists integrate the service with enterprise directories, multi-factor authentication systems, and identity engines to enforce role-based access control.
- Cisco Identity Services Engine and Secure ACS deployments
- Aruba ClearPass Policy Manager configurations
- Open-source tacacs+ daemon setups on Linux servers
- Enterprise directory integration with Active Directory and LDAP
- Privilege level and command authorization sets on network appliances
Real-Time Command Accounting and Compliance
Organizations running critical infrastructure in Germany rely on full audit trails for administrative sessions. With this protocol, every executed command is logged with timestamps and user identities, satisfying strict compliance mandates and internal audit standards across sensitive operational environments.
Multi-Vendor Heterogeneous Fabrics
While developed primarily within Cisco environments, the protocol operates seamlessly across appliances from Juniper, Arista, Fortinet, and Palo Alto Networks. Specialists build unified authorization rule sets that apply consistently across edge routers, core switches, and perimeter firewalls.
Critical Triggers for External Expertise
Companies hire external specialists during major network modernization programs, zero-trust access rollouts, or vendor consolidations. Seasoned contractors deliver immediate value by resolving complex policy inheritance challenges, migrating legacy daemon deployments, and stabilizing high-availability failover architectures.
Evaluating Senior Freelance Specialists
Top specialists demonstrate extensive experience with AAA architecture, protocol-level debugging using network analyzers, and distributed deployments. For engagements in Germany, they bridge technical security controls with corporate governance requirements, whether delivering work remotely or participating in secure on-site data center cutovers.
Frequently asked questions
Not sure where to start with TACACS+? These answers cover the essentials.
Organizations deploy TACACS+ to manage and govern administrative access to network devices such as switches, routers, and firewalls. Unlike general network access solutions, it enables administrators to restrict specific shell commands per user role and maintain precise session logs.
While RADIUS combines authentication and authorization into one step and uses UDP, TACACS+ separates authentication, authorization, and accounting into distinct functions over reliable TCP. Furthermore, it encrypts the entire packet body, making it far more secure and flexible for administrative device control.
Enterprise implementations commonly run on Cisco ISE (Identity Services Engine) or Aruba ClearPass Policy Manager. Many organizations also leverage high-performance open-source daemons such as tac_plus on Linux for specialized, vendor-agnostic infrastructure.
A qualified TACACS+ professional typically holds enterprise networking and security certifications alongside deep knowledge of directory services like Active Directory. They should be adept at packet inspection, script automation, and constructing granular command privilege matrices.
Most policy definitions, configuration scripts, and server builds for TACACS+ happen remotely via secure administrative bastions. However, enterprises in Germany operating critical infrastructure often request that final production cutovers and on-premise hardware testing involve hybrid or on-site support.
By generating per-command accounting logs, TACACS+ gives security teams verifiable records of every action taken during administrative sessions. This capability directly supports regulatory audits by proving who accessed a network device and exactly which configuration changes were made.
Teams frequently encounter misconfigured authorization sets that inadvertently lock out legitimate administrators or grant excessive shell privileges. Engaging an expert in TACACS+ ensures that fallback local authentication methods remain properly staged and policy inheritance trees are thoroughly vetted before cutover.
Yes, because physical data centers, out-of-band management fabrics, and cloud edge routers still require strict human administrative access boundaries. Modern network deployments integrate TACACS+ servers alongside automated identity pipelines to ensure consistent access enforcement across hybrid infrastructure.
The average hourly rate of freelancers in Germany who have used TACACS+ in their recent projects is 100 €, which corresponds to a daily rate of about 802 € based on an 8-hour working day.
