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
Access control for networks
TACACS+ is used to control who can log in to network devices and what they can do after login. It is common in routers, switches, firewalls, and other infrastructure where command-level control matters. Teams use it to separate authentication, authorization, and accounting.
Where it fits
It is often chosen in Cisco-heavy environments, but it also appears in mixed vendor networks that need consistent admin access policies.
- Centralized device login control
- Role-based command authorization
- Accounting for admin actions
- Policy separation for shared infrastructure
Typical delivery work
Strong specialists set up TACACS+ servers, define policy sets, and connect network devices to the service. They also troubleshoot failed logins, privilege mapping, and fallback behavior when the server is unavailable. In Germany, this work often supports enterprise networks, industrial sites, and regulated environments that need clear access logs.
Ecosystem and skills
A good TACACS+ professional understands AAA concepts, device templates, and secure secret handling. They often work with Cisco ISE, tac_plus, RADIUS, LDAP, Active Directory, and SSH-based administration flows. The best experts can read device logs and trace where authentication or authorization breaks.
When companies bring in freelancers
Companies usually look for freelance help during migrations, audits, incident recovery, or new site rollouts. They also bring in specialists when access rules are inconsistent across teams or when admin access needs to be tightened without disrupting operations.
- Replace local device accounts
- Standardize admin access
- Review privilege levels
- Document operational procedures
What strong experts deliver
Strong TACACS+ experts keep access simple for admins and strict for the business. They produce clear policy design, tested rollback steps, and clean documentation for handover. They also know how to balance security, usability, and device compatibility across environments.
Frequently asked questions
Not sure where to start with TACACS+? These answers cover the essentials.
TACACS+ is used to control administrative access to network devices and to record what users do after they log in. It is a common choice when companies want separate control over authentication, authorization, and accounting. That separation makes it easier to apply different permissions to different specialists and teams.
TACACS+ is usually chosen for device administration, while RADIUS is more common for user access to Wi-Fi, VPN, or general network services. TACACS+ separates the login process from command authorization more cleanly, which is useful on routers and switches. Many teams still use both, depending on the access case.
A strong TACACS+ specialist should also know AAA concepts, SSH access flows, and device-side policy configuration. Familiarity with Cisco ISE, Active Directory, LDAP, and log analysis is often valuable. In practice, the work is as much about troubleshooting and policy design as it is about the protocol itself.
TACACS+ expertise is often needed for access-control rollouts, device migrations, policy cleanups, and security audits. It also comes up when companies replace local accounts on infrastructure devices or want better traceability for admin actions. A freelancer can usually help with design, implementation, validation, and handover documentation.
A TACACS+ project needs someone who has worked through real device access issues, not just read the documentation. The right level depends on scope: a simple server integration is different from a large policy redesign across many device types. Look for proven work with login flow, privilege mapping, and rollback planning.
TACACS+ work is often done remotely because most tasks involve policy design, server setup, and controlled testing. On-site support can help during cutovers, incident recovery, or when a company wants direct coordination with operations teams in Germany. Many projects use a mix of both, depending on risk and access to the network.
Look for clear examples of TACACS+ deployments, not just general network security experience. Good specialists can explain how they handled authorization rules, failure scenarios, logging, and fallback access. They should also provide clean documentation and show they understand the device types in your environment.
TACACS+ is strongly associated with Cisco, but it can still be useful in mixed-vendor networks if the devices support it. The key question is whether your infrastructure devices can talk to the same AAA service and enforce the policy you need. A good specialist will check compatibility before the design is finalized.
