24/7 on-call & support - Guarantee the continuity of your IT services

IT Systèmes on-call service enables a technician or engineer to be available on call, according to a pre-defined schedule. This system is particularly well suited to companies with several sites, foreign subsidiaries or teams working in different time zones. In the event of a critical incident, the on-call employee is contacted immediately, assesses the situation and intervenes remotely or on-site, depending on the severity of the incident. All interventions are traced and integrated into our centralized ticketing system to ensure complete follow-up.

For high-availability infrastructures, IT Systèmes offers a true 24/7 service operated from France. Our teams continuously monitor systems, applications, networks and cloud environments. In the event of an alert, intervention is immediate, whatever the time of day or time zone. This system is particularly well suited to multi-site companies, industrial environments, healthcare establishments, or international groups requiring bilingual support.

Our supervision platforms monitor server availability, backup health, network security and application performance in real time. In the event of an anomaly, an alert is automatically sent to our HNO engineers, who initiate the analysis and remediation protocol without delay.

Each HNO contract is defined with precise procedures: incident classification, criticality thresholds, escalation levels, communication channels and emergency contacts. Our teams ensure complete follow-up through to resolution, with a detailed report sent to the customer as soon as the incident is over.
