Your business needs, our network services
SIER offers its technical expertise to support you as you develop your network infrastructure.
From auditing and training to architecture and integration, our 4 strategic areas of focus are part of a long–term vision for your infrastructure.
Improve security and performance, while reducing your costs, by making the most of your network.
Audit
To diagnose a complex problem, to better prepare your budget, or to ensure compliance with best practice, a network audit is an essential step.
Our audits will give you a clear, exhaustive and impartial view of the state of your IT network. We identify the strengths, weaknesses and opportunities for improvement in your infrastructure, to lay the foundations for optimal operation.
- What equipment needs replacing?
- What investments are needed to meet the future requirements of my users?
- What technical improvements could reduce the cost of my infrastructure?
- What major changes will require the intervention of an external service provider?
Architecture
However powerful the switches and advanced the technology, a poorly designed IT network will never meet your expectations. The architecture of a network represents the foundations on which your services and your business can develop.
SIER can help you design your future network or transform your existing one, offering its expertise in both the physical architecture and the logical design best suited to your needs.

Physical architecture
Choose the best equipment, its location and interconnections to build a reliable, scalable and cost-effective network.

Logical architecture
Optimise your hardware resources and increase the security of your infrastructure with a customised logical architecture.
Deployment
SIER can help you with your simple to moderately complex projects, regardless of the manufacturer of your infrastructure (Cisco, Juniper, HP, etc.).
However, our real speciality lies in Extreme Networks solutions, where we have a perfect command of LAN and Wi-Fi technologies, and which we can use to support you in your complex projects.
- Installation and configuration of wired and wireless corporate networks.
- Deployment of authentication solutions (802.1x).
- Interconnection with the cloud.
- Deployment of Wi-Fi captive portals.
Training
SIER is committed to a pedagogical approach and values the sharing of knowledge. For a technology to work, it has to be adopted, and for that we offer technical training for your IT teams.
SIER offers training tailored to your infrastructure to meet your needs.
- A trained team is a more confident, proactive team, able to maximise the technologies in place.
- A trained team knows how to anticipate threats and reduce risks.
- A trained team solves more problems autonomously, limiting the need for costly external assistance.
- A well-managed network means greater stability, fewer breakdowns and fewer premature renewals.
