Software-Defined Wide Area Network (SD-WAN) Management and Operation Training Course

Matrix is an open protocol designed for secure, decentralized, real-time communication. Organizations are increasingly choosing Matrix paired with the Element client as a robust alternative to Slack and Microsoft Teams, enabling them to maintain end-to-end encryption, keep data within their own premises, and establish trusted federations with external partners.

This live, instructor-led training in Greece (online or onsite) is aimed at network and system administrators who wish to implement enterprise-grade network monitoring using open-source tools without vendor dependencies.

By the end of this training, participants will be able to deploy LibreNMS and Zabbix, monitor network devices, create dashboards and alerts, implement distributed monitoring, and integrate with external systems.

In this instructor-led, live training in Greece (online or onsite), participants will learn how to use ONAP to automate networking services.

By the end of this training, participants will be able to:

• Understand, install and configure the various components in the ONAP ecosystem.
• Carry out real-time, policy-driven orchestration and automation of physical and virtual network functions.
• Design, create, orchestrate, and monitor VNFs, SDNs and other network services.
• Efficiently manage the entire networking lifecycle using a software-driven approach.
• Develop, deploy, and scale a network using the latest open source technologies and practices.

The 'Computer Network Security – How to Secure Your Services' training presents mechanisms and services that secure modern network solutions. It covers the basics of ensuring data confidentiality and integrity, the use of encryption, certificates, public key infrastructure (PKI), and secure password storage. The course also discusses network security protocols and services, security systems, wireless network protection, connecting corporate branches, and security testing through penetration testing, network scanning, and vulnerability detection.

Synapse is the reference homeserver implementation for the Matrix protocol, enabling decentralized, end-to-end encrypted messaging. This instructor-led live training (online or on-site) targets intermediate DevOps engineers and system administrators who aim to replace cloud chat platforms with a self-hosted, federated messaging infrastructure using Synapse and Element.

Uptime Kuma is an easy-to-use, self-hosted monitoring tool that tracks the availability of websites, services, and infrastructure. It replaces Pingdom, Datadog Synthetics, and UptimeRobot for teams who prefer to keep their monitoring data under their own control. This instructor-led, live training (online or onsite) targets beginner-to-intermediate SREs and DevOps engineers aiming to replace cloud uptime monitoring with a self-hosted, sovereign status tracking platform.

OpenVPN and WireGuard are the two dominant open-source VPN protocols. Running your own VPN server ensures that no third-party provider can log traffic metadata, inject advertisements, or comply with foreign data requests. This training covers both protocols for different threat models and performance requirements.
