📊 Overview

The Network
Your Business
Depends On

The network is the foundation of every IT service. CloudSourceIT's networking engineers hold Cisco CCNP, CCIE, and Juniper JNCIA certifications and have designed campus, WAN, and data centre networks for organisations ranging from 50 users to 10,000-user enterprises across the GCC.

We design with resilience, segmentation, and manageability at the core, leveraging modern protocols (OSPF, BGP, VXLAN, EVPN) and software-defined approaches (SD-WAN, IBN) to future-proof your network investment.

🏢 Use Cases

Built for Your Industry

🏢
Corporate Campus Refresh
Replace end-of-life switches with Wi-Fi 6-ready PoE+ access layer, redundant distribution switches, and 10G/40G uplinks, zero-downtime cutover in phased weekends.
🏦
Bank Branch WAN
Replace costly MPLS links with Cisco SD-WAN using dual internet broadband, cutting WAN costs by 60% while improving application performance with QoS.
🏭
OT/IT Network Separation
Segment factory OT networks from corporate IT using dedicated VRFs and ACLs, reducing lateral movement risk while enabling monitored data flows for analytics.
🏛️
Government Secure Network
High-security campus design with 802.1X port authentication, CoA, and NAC enforcement, only approved devices access government network resources.
☁️
Data Centre Fabric
Leaf-spine VXLAN fabric connecting 50-node compute clusters to ToR switches with BGP EVPN multi-tenancy, supporting thousands of VMs with microsegmentation.
🏥
Hospital Network Redesign
Separate clinical, admin, IoT medical device, and guest wireless VLANs with firewall enforcement at each boundary, meeting healthcare network security mandates.

✅ Why CloudSourceIT

The CSIT Advantage

🎓
CCIE/CCNP Certified
Our network engineers hold the highest Cisco certifications (CCIE R&S, CCIE DC) alongside Juniper JNCIA, ensuring your network is designed and configured correctly.
📐
Design Before Deploy
Every project starts with an HLD (High-Level Design) and LLD (Low-Level Design) document, reviewed and signed off before a single cable is touched.
🔄
Zero-Downtime Migrations
Production network migrations planned at the port level, phased cutovers with rollback procedures ensuring your business continuity throughout the refresh.
🤖
Automation Ready
We deliver Ansible playbooks and Python scripts alongside manual configurations, enabling your team to automate future changes consistently.
🔐
Security at Every Layer
802.1X, port security, DHCP snooping, Dynamic ARP Inspection, and private VLANs built into campus designs, network security from the access port up.
📋
Full Documentation
As-built diagrams (Visio), configuration backups, IP address management (IPAM) spreadsheets, and change logs, delivered at project completion.
🔄 Our Process

How We Work

1
Network Audit
Collect existing topology, config, utilisation data, and identify pain points and risks.
2
HLD / LLD Design
Produce High and Low Level Design documents with topology diagrams and protocol specifications.
3
Lab Validation
Validate configuration in a lab or test environment before production deployment.
4
Phased Deployment
Implement in planned phases, core first, then distribution, then access, with rollback capability.
5
Handover
As-built documentation, config backups, IPAM, and knowledge transfer to your team.
