Case Study: Viettel Group achieves 50% fewer security incidents and streamlined network security with Fortinet

How Viettel Safeguards Its Network and Customers with Fortinet

Viettel, a leading telecom and technology conglomerate with 50,000 employees and 110 million customers across Vietnam and Southeast Asia, faced a rapidly deteriorating threat landscape—rising data breaches, phishing and DDoS attacks—while needing to scale infrastructure, protect customer data, and maintain uninterrupted services and regulatory compliance.

Viettel deployed a Fortinet security fabric—FortiGate next‑generation firewalls (1800F/2200E/600F/2600F) plus FortiManager and FortiAnalyzer—to centralize policy management, segment traffic, and secure remote access. The rollout simplified administration and reporting, supported a distributed workforce, and delivered measurable impact: ~50% fewer security incidents, roughly 30% savings in incident response costs, and 24x7 protected connectivity for internal users and customers.
