How Exelcom Migrated NOD National Optical Distribution to Business Internet, Cisco Security, and Webex Calling Across Three States

The Challenge

NOD National Optical Distribution operates across three states — Sydney, Brisbane, and Adelaide — and had accumulated a mixed technology environment over the years: business internet through an incumbent carrier, no unified security stack across sites, and an ageing iPECS on-premise phone system that couldn't keep pace with how the business operated. NOD needed a single technology partner who could take ownership of connectivity, security, and communications across all three locations without disrupting day-to-day operations.

What Exelcom Delivered

Exelcom took over NOD's technology environment end to end — replacing the incumbent carrier, deploying a consistent Cisco security stack across all three sites, and modernising voice communications with Webex Calling.

• Business internet migration from the incumbent carrier to Exelcom-managed connections across Sydney, Brisbane, and Adelaide — coordinated cutovers with no service gaps
• Cisco Umbrella deployed across all sites — providing DNS-layer security and web filtering that protects every device on the network, including remote workers, from internet-based threats
• Cisco Duo MFA enforced across the organisation — securing access to corporate systems and cloud applications with strong multi-factor authentication for all staff
• Cisco Secure Client deployed across all locations — providing encrypted remote access and enforcing endpoint security posture for staff working inside and outside the office
• Webex Calling migration from the legacy iPECS on-premise phone system — delivered via Cisco Cloud Connect PSTN, giving NOD a fully cloud-managed calling platform with no on-site PBX hardware to maintain
• Single Cisco Control Hub instance managing calling and security policies across all three states — giving IT and management a unified view of the entire communications environment
