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
Core function
TACACS+ is a protocol for centralized authentication, authorization and accounting, commonly called AAA, for network access. It separates authentication from authorization and encrypts the full packet body, making it suitable for controlling administrative access to routers, switches, firewalls and other infrastructure.
Typical deployments
TACACS+ supports centralized access policies across enterprise and service-provider environments. Companies use it to control who can access network devices, which commands they may run and how administrative activity is recorded.
- Network device administrator access
- Role-based command authorization
- Centralized login and audit trails
- Privileged access workflows
Ecosystem and tooling
Strong TACACS+ specialists work with Cisco IOS, IOS XE, NX-OS and network security appliances, as well as Linux-based TACACS+ implementations. They connect the service to LDAP, Active Directory, RADIUS, MFA tools and certificate-based identity systems, while managing encryption keys, policy files and service health.
When expertise matters
Freelance expertise helps when a company is replacing local device accounts, consolidating network identity services or investigating inconsistent command permissions. In Germany, specialists may support regulated industries and distributed infrastructure remotely, with on-site collaboration where network changes require local access or coordinated maintenance.
- Plan a TACACS+ migration
- Resolve authentication or authorization failures
- Harden device access and shared secrets
- Document policies and operational handover
Delivery skills
A capable professional maps identity groups to device roles without creating excessive privilege. They test fallback behavior, account lockout handling, command sets and logging before rollout. They also understand change control, network segmentation, DNS, certificates, firewalls and the operational impact of an unreachable authentication service.
Choosing a specialist
Look for practical experience with the exact network vendors, operating systems and identity sources in scope. A strong specialist can explain the difference between authentication success and command authorization, reproduce failures with logs and packet captures, and design resilient access without weakening accountability. Clear documentation and safe rollback plans are essential deliverables.
Frequently asked questions
Not sure where to start with TACACS+? These answers cover the essentials.
TACACS+ is used to centralize authentication, authorization and accounting for administrative access to network equipment. It can verify identities, assign device roles, restrict individual commands and record activity for review.
TACACS+ separates authentication, authorization and accounting and encrypts the packet body, while RADIUS combines authentication and authorization more closely and protects only selected fields. TACACS+ is often preferred for detailed control of administrator commands on network devices.
A strong TACACS+ freelancer usually understands Cisco IOS, IOS XE or NX-OS, firewalls, Linux services and network troubleshooting. Useful adjacent skills include LDAP or Active Directory integration, MFA, certificates, DNS, logging, automation and secure change management.
The right level depends on the scope. A small policy change may need focused TACACS+ configuration skills, while a migration or multi-vendor rollout requires someone who can design redundancy, test authorization rules, plan fallback access and manage production changes safely.
Much TACACS+ work can be completed remotely through controlled access to network devices, identity systems and logs. On-site collaboration in Germany can still help when hardware access, maintenance windows, segregation requirements or coordination with local operations teams are involved.
TACACS+ can use LDAP or Active Directory as an identity source, then map directory groups to device roles and command permissions. The integration must account for service accounts, directory availability, group changes, secure transport and emergency access.
Ask for examples involving the relevant device vendors, identity sources and authorization model. A good TACACS+ specialist should explain testing methods, logging, redundancy, secret management, rollback procedures and how they avoid locking out all administrative access.
A high-quality TACACS+ implementation uses least-privilege roles, resilient service nodes, protected shared secrets and clear audit records. It also includes tested break-glass access, documented policies, monitoring and a repeatable process for adding or removing administrators.
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 801 € based on an 8-hour working day.
