Founder, Agents for Day-to-Day Business at CXO AI OS
CXO AI OS is an agent system made up of six building blocks. Instead of using AI as a chat window, it creates a system that understands a company’s context, makes decisions according to its rules, and acts on its behalf.
- For mid-sized companies: a guided sprint followed by operation for a team, department, or prioritized cluster, based on an AI assessment
- For self-employed professionals: a program in which participants build their own agent system
- Sequence in the company: assessment, prioritization, sprint, operation
- Implementation in Claude Cowork or ChatGPT Work, without coding
- Architecture: Chief of Staff, Goals, Advisors, Agents, Context, Catalog

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 RADIUS does
RADIUS, short for Remote Authentication Dial-In User Service, is a protocol for centralised authentication, authorisation and accounting. It lets network access systems verify identities and apply access policies through a shared service. Companies use it for Wi-Fi, VPN, wired access, firewalls and network equipment.
Core architecture
A RADIUS deployment usually connects a network access server with a RADIUS server and an identity source. The access server sends an Access-Request, while the server returns an approval, rejection or challenge. Accounting messages can record session starts, stops and usage details for auditing and operations.
Ecosystem and tooling
FreeRADIUS is the most common open-source implementation and supports extensible modules, policy rules and multiple identity back ends. Experts may also work with Microsoft NPS, Radiator or vendor-specific RADIUS services. Common integrations include LDAP, Active Directory, SQL databases, certificates, EAP methods, network access control and SIEM tooling.
- Configure FreeRADIUS policies and virtual servers
- Integrate PEAP, EAP-TLS or other 802.1X methods
- Connect RADIUS to LDAP, Active Directory or SQL
- Test accounting, failover and device compatibility
Typical projects
Companies bring in RADIUS specialists to centralise access across offices, campuses, data centres and remote users. Typical work includes replacing shared Wi-Fi keys with identity-based access, securing VPN authentication, introducing certificate-based network access and troubleshooting failed authentication between devices, policies and identity stores. In Germany, this expertise is relevant to industrial sites, healthcare organisations, education and distributed enterprises.
When freelance expertise helps
External professionals are useful during a migration, an 802.1X rollout or an urgent access incident. They can review an existing configuration, map policies to business roles, harden encryption and document operational procedures. Remote collaboration often works well for configuration and testing, while on-site support can help with wired and wireless rollout in German facilities. Clear German or English documentation should be agreed early.
What strong specialists bring
Strong RADIUS professionals understand the protocol as well as the surrounding network and identity layers. They can read packet captures, diagnose EAP and certificate failures, distinguish client issues from policy errors and design resilient services. Look for practical knowledge of FreeRADIUS or the selected implementation, network access control, directory services, PKI, logging and secure change management.
Frequently asked questions
Curious about RADIUS? Here are the answers that come up again and again.
RADIUS is used to authenticate users and devices, apply access rules and record network sessions. It commonly supports enterprise Wi-Fi, VPNs, wired 802.1X access, firewalls and remote access services.
RADIUS is widely used for network access authentication and accounting, while TACACS+ is often chosen for detailed administrative control over network equipment. The right choice depends on device support, command-level authorisation needs and the existing identity architecture.
A strong RADIUS specialist should understand TCP/IP networking, 802.1X, EAP, certificates and PKI. Experience with LDAP, Active Directory, FreeRADIUS, network access control, firewalls and packet analysis is also valuable.
The required background depends on the scope. A basic configuration may need focused implementation experience, while a large 802.1X or certificate-based rollout calls for a professional who has handled identity integration, failure recovery, migrations and production troubleshooting.
Much of RADIUS configuration, policy design and log analysis can be completed remotely through controlled access and test environments. On-site work may still be useful for wireless surveys, switch changes, certificate deployment or troubleshooting physical network access.
Ask the specialist to explain a real authentication flow from the network access device to the identity store. Review their approach to EAP failures, certificate validation, policy testing, logging, rollback and documentation rather than relying only on familiarity with product names.
FreeRADIUS is an open-source server implementation of the RADIUS protocol, not a separate authentication standard. It provides modules and policy tools for connecting network devices with directories, databases and certificate-based identity systems.
Define the access methods, network devices, identity sources, security requirements and expected support model. German companies should also agree whether the work requires on-site presence, whether documentation must be written in German, and how production changes will be approved.
The average hourly rate of freelancers in Germany who have used RADIUS in their recent projects is 99 €, which corresponds to a daily rate of about 793 € based on an 8-hour working day.
Of the freelancers in Germany who have used RADIUS in their recent projects, 81% hold at least a Bachelor's degree, 38% hold at least a Master's degree, and 4% hold a doctorate.
On average, freelancers in Germany who have used RADIUS in their recent projects have 28 years of professional experience, with a single engagement typically lasting around 2.4 years.
The most common languages among freelancers in Germany who have used RADIUS in their recent projects are English (100%), German (97%), and Spanish (13%).
The most common industries among freelancers in Germany who have used RADIUS in their recent projects are Information Technology (94%), Telecommunication (61%), and Manufacturing (58%).
