High-Availability Cybersecurity Deployment for Toll-Road Infrastructure

A toll-road operator required a secure network architecture capable of protecting critical business connectivity while maintaining service availability.

The environment relied on two independent internet service providers. A firewall or WAN failure could disrupt critical connectivity and operational services.

The customer therefore required both firewall redundancy and ISP resilience.

The solution needed to:

  • Secure internet connectivity
  • Support dual ISP connections
  • Minimize single points of failure
  • Provide high-availability firewall operation
  • Establish appropriate security policies
  • Provide post-deployment support

SANSO deployed a pair of enterprise next-generation firewalls in High Availability (HA) configuration.

Both ISP connections were integrated into the security architecture, with firewall policies, routing, NAT, security profiles and HA parameters configured and validated onsite.

The deployment included configuration, testing, documentation and basic L1 support with OEM coordination.

The customer received a secure network with firewall redundancy and dual-WAN connectivity, reducing dependency on individual network components.
