systems and networking: a fast-evolving sector
Systems and networking infrastructure remains the foundation of any organisation, even in the cloud era. Hybrid architectures combine on-premises Active Directory and Azure AD, Windows Server and Linux virtual machines, Cisco equipment and cloud services, Windows and macOS endpoints managed by MECM or Intune. This structural technical complexity creates a continuous demand for system administrators, network engineers, network security engineers and IT technicians able to manage multi-vendor environments.
A recognised systems and networking training opens access to structuring technical positions and to reference certifications on the Swiss market: CompTIA A+ and Network+, Cisco CCNA and CCNP, Microsoft Windows Server certifications (AZ-800, AZ-801), Linux Foundation, or CompTIA Security+. ITTA offers a catalogue of training courses in this domain, from generalist fundamentals to expert certifications, delivered by certified trainers with hands-on labs on the official Microsoft, Cisco and Linux environments.
A recognised systems or networking certification is a concrete professional investment, securing your employability and opening access to structuring technical positions in Geneva and Lausanne.
Which systems and networking skills to develop
General IT fundamentals (CompTIA and Linux)
For reskilling or junior profiles, CompTIA A+ is the most recognised entry point: hardware, operating systems, workstation troubleshooting, end-user support. CompTIA Network+ covers networking basics, TCP/IP protocols, routing, wireless and network security fundamentals. CompTIA Security+ adds the operational security dimension essential to any administrator. On the open source side, Linux Essentials introduces Linux distributions and command line, a universal skill in cloud and DevOps environments.
Microsoft Windows Server and Active Directory
Windows Server administration remains central in most organisations. Windows Server Administration covers the operational fundamentals: user management, file shares, group policies, network services. Identity with Windows Server goes deeper into Active Directory, identity management and federation. For hybrid environments, Administer Windows Server Hybrid Core Infrastructure (AZ-800) and Configure Windows Server Hybrid Advanced Services (AZ-801) prepare for the Microsoft Certified: Windows Server Hybrid Administrator Associate certification. To automate administration, Automate Administration with PowerShell (AZ-040) is the reference course.
Cisco: routing, switching, network security
Cisco remains a major actor in enterprise network infrastructure. Designing Cisco Enterprise Networks (ENSLD) is the network architect path, relevant for CCNP profiles designing LAN, WAN, SD-WAN and campus topologies. Implementing and Operating Cisco Security Core Technologies (SCOR) is the pivot course for the CCNP Security certification and covers VPN, NGFW, access control and network security automation. Our catalogue also covers enterprise networking, wireless, service provider and data center for the most advanced Cisco profiles.
Endpoint and asset management
Centralised client endpoint management remains an important operational topic. Administering Configuration Manager (MECM) covers deployment, updates and asset management with Microsoft Endpoint Configuration Manager. This skill remains central for IT support teams managing a heterogeneous Windows estate, and complements Microsoft 365 Endpoint Administrator (MD-102) training on the Intune and Windows Autopilot dimension.
From beginner to expert: your progression
A junior or reskilling profile generally starts with CompTIA A+ to acquire hardware and systems basics, then continues with CompTIA Network+ for networking and Security+ for operational security. An experienced Windows administrator can enter directly through Windows Server Administration and Identity with Windows Server, then aim for AZ-800 and AZ-801 for the hybrid dimension and the Microsoft certification. Cisco network profiles progress from CCNA to CCNP through enterprise networking, security or data center paths according to their orientation. Security profiles combine Security+, Cisco SCOR and the audit and cybersecurity training for security engineer or SOC analyst positions.
Combining systems and networking with other expertise
Systems and networking are inseparable from the other IT domains. Cloud computing training covers Azure and AWS certifications which build on these fundamentals. The audit and cybersecurity domain goes beyond the security modules embedded in CompTIA and Cisco. Continuous-delivery profiles extend their path with DevOps, covering Kubernetes, Docker, Terraform and infrastructure-as-code automation. For administrators managing SQL Server or PostgreSQL databases, the analytics and data management domain provides DBA skills. Finally, ethical hacking offers a complementary offensive approach for advanced security profiles.
systems and networking sessions on-site and virtual
All our systems and networking training courses are available on-site in our Geneva and Lausanne centres, as well as in interactive virtual classroom. Our sessions open every 5 weeks, so you can start your training when it suits you. The deliberately modest size of our groups guarantees attentive support, and each course includes hands-on labs on the official Microsoft, Cisco, Linux and CompTIA environments depending on the programme.

FAQ
Where to start in systems and networking without experience?
CompTIA A+ is the most recognised entry point for reskilling profiles. It covers hardware, systems and troubleshooting. Continue with CompTIA Network+ for networking basics, then Security+ for operational security. This is a coherent and accessible trio without advanced IT prerequisites.
Which Cisco certification should I choose in 2026?
CCNA remains the most recognised entry-level Cisco certification. To progress, CCNP through enterprise networking, security or data center paths according to your orientation. Designing Cisco Enterprise Networks (ENSLD) targets architects, and SCOR is the pivot of the CCNP Security path.
How long does it take to become a certified Windows Server administrator?
Plan 4 to 5 days for Windows Server Administration and the same for Identity with Windows Server. To aim for the Microsoft Windows Server Hybrid Administrator Associate certification, add AZ-800 and AZ-801 (10 days total). With review, expect 3 to 4 months to obtain the associate certification.
What professional funding options are available?
Several professional funding solutions can be considered depending on your situation and your employer. Our team helps you identify the options that fit your profile and supports you in preparing the application file.
