The starting point
The operational need comes first: visibility, continuity, controlled access or better support.
Open-source expertise for SMEs
Architecture, deployment and maintenance of open-source solutions.
Sumatoni integrates open-source technology into the IT environment and organises its operation, maintenance and support.
Virtualisation and backupMonitoring and securityRemote access and IT support
The work
Sumatoni designs, deploys, documents and maintains the selected solutions within the wider IT environment.
The outcome
An environment that remains understandable, supportable and proportionate to the organisation.
Representative technologies
An ecosystem organised around four operational needs.
These are examples from solutions Sumatoni deploys. They illustrate the scope of the work rather than define a closed catalogue.
INF
Infrastructure and continuity
Proxmox VE · Proxmox Backup Server · Ubuntu Server
Virtualise workloads, organise backup and recovery, and host services on a lightweight Linux foundation.
MON
Monitoring and security visibility
Zabbix · Wazuh
Monitor availability and performance, then consolidate the events needed for security analysis.
ACC
Remote access and administration
WireGuard · OpenVPN · JumpServer
Reduce direct exposure and organise individual, site-to-site and administrative access.
OPS
IT asset management and support
GLPI
Link support requests to an asset record and retain a usable intervention history.
Observed changes
What these solutions changed for clients.
The value lies in the operating situation after deployment, not in the product name.
Zabbix
Monitoring sized to the actual environment
Zabbix is used for environments ranging from a few devices to several hundred. Discovery facilitates onboarding, while High and Critical events can be sent through messaging according to the client’s priorities.
VPN · WireGuard
Local services without direct Internet exposure
A locally hosted business tool is no longer directly exposed to the Internet. Users connect through a VPN with individual, separately revocable access. WireGuard also links two sites through an encrypted site-to-site tunnel.
Wazuh
Security events brought into one place
Wazuh consolidates system logs and network events so information that would otherwise remain scattered can be reviewed from a common view during detection and investigation.
GLPI
Support linked to the actual IT estate
GLPI brings support requests and the asset database together. Interventions retain a history and incidents can be connected to the equipment concerned.
The technology list is not the service.
The examples above come from real deployments, but the choice always starts with the client’s environment and constraints.
Open-source is retained when it provides the right operational result. A commercial solution remains an option when it is the better fit.
Frequently asked questions
Do you only deploy these tools?
No. They are representative examples from a broader set of solutions used according to the project.
Does open-source mean without support?
No. The deployment also defines the updates, backup, monitoring, documentation and support that need to be organised.
Use open-source where it creates operational value.
Sumatoni can assess which solutions fit the environment and how they should be operated.
