Strengthening Network Security and Performance with SD-WAN and SASE Implementation

Logistics & Infrastructure

Problem / Solution Overview

A leading government organization responsible for implementing e-governance initiatives and maintaining IT infrastructure sought to modernize its network architecture. The department’s legacy State Wide Area Network (SWAN) relied on low-bandwidth MPLS links, resulting in frequent performance issues, inconsistent connectivity, and rising operational costs.

With the growing shift toward hybrid and remote work, the department needed a secure, scalable, and centrally managed network solution that could deliver high availability, automation, and visibility across users and locations.

SM Networks addressed this challenge by deploying a Fortinet Secure SD-WAN architecture, enhanced with SASE integration and centralized management capabilities, enabling seamless connectivity and unified security across all endpoints.

Key Deliverables

  • Fortinet Next-Generation Firewall (NGFW) with native SD-WAN and UTM features.
  • Fortinet Authenticator for centralized user access and SAML-based authentication.
  • Zero Touch Provisioning (ZTP) for quick and consistent deployment.
  • Security as a Service Edge (SASE) for secure access across on-prem, cloud, and remote users.
  • Central Log Analyzer for secure log retention and compliance monitoring (180 days).

Client Impact

  • Cost Efficiency: Migration from MPLS to Internet Leased Lines reduced operational expenditure significantly.
  • Enhanced Performance: Application-aware routing and local breakout improved responsiveness and user experience.
  • Automation & Scalability: ADVPN features enabled automatic adaptation to ISP or network changes.
  • Unified Security: Consistent enforcement of security policies across office, home, and remote environments
  • Centralized Control: Simplified management and faster deployment through ZTP and integrated monitoring tools.

Technologies Used

  • Enterprise-grade servers with high-availability configurations.
  • SAN storage systems for scalable data handling.
  • Tape library for secure data backup and retention.
