Managed Network Services vs In-House Team: How to Decide

Q: Quel est le coût moyen d'un ingénieur réseau interne ?

Un ingénieur réseau senior coûte 70 000-90 000 EUR brut annuel (charges comprises : 100 000-130 000 EUR). Avec les frais de recrutement, formation, outils et management, le coût complet atteint 130 000-170 000 EUR/an.

Q: L'infogérance réseau coûte-t-elle moins cher ?

Pour une PME de 200-500 utilisateurs, l'infogérance coûte 3 000-8 000 EUR/mois (36 000-96 000 EUR/an), souvent moins cher qu'un ingénieur interne à temps plein. Pour une ETI de 1000+, l'équipe interne est souvent plus rentable.

Q: Peut-on combiner infogérance et équipe interne ?

Oui, le modèle hybride est le plus courant : un coordinateur réseau interne qui pilote un prestataire d'infogérance. L'interne connaît le contexte métier et pilote la stratégie, le prestataire apporte l'expertise technique et la couverture 24/7.

Models

100% In-House Team

Full control
In-house expertise
Cost: salaries + training + tools
Risk: staff turnover and skills shortages

Fully Managed Services

Full outsourcing (Atos, Capgemini, Sopra, Infosys)
Contractual SLA
Price: €3-8k/month per monitored switch/FW
Risk: lock-in and loss of in-house expertise

Mid-Market MSP (Managed Service Provider)

More agile than global managed service providers
Price: €50-200/user/month depending on scope
Target customers: SMEs with 50-500 users
Examples: Econocom, SCC, DLC, OPTINOC Managed

Hybrid Model (Recommended)

In-house team for strategy + design
MSP for operations + monitoring + hands-on support
L1-L2 handled by the MSP, L3 in-house
The best of both worlds

Selection Criteria

Company size: <200 users → MSP, >2000 → hybrid
