A major institution operating across North Africa* needed to redesign a highly exposed network environment that had become too fragmented to support the scale, security posture, and service continuity the business now required. The programme centred on a complex Cisco infrastructure spanning core routing and switching, site connectivity, perimeter security, wireless access, and network segmentation across a distributed operating footprint. This was not a refresh exercise. It was a large capital programme tied to the resilience of the institution’s wider digital environment. Qabas was engaged to design the target Cisco architecture, structure the solution at enterprise level, and create an implementation ready platform capable of supporting mission critical operations with stronger control, clearer segmentation, and materially higher fault tolerance.
The Situation
The client’s challenge was not simply ageing network hardware. The deeper issue was that the estate had evolved in layers, with individual expansions and local fixes gradually producing an architecture that was technically capable in parts but weak in aggregate. Core and distribution logic were not sufficiently standardised. Security controls were uneven across sites. Routing, switching, wireless, and perimeter decisions had not been brought together under one coherent design. As reliance on digital services increased, those weaknesses became more consequential.
In practical terms, the network had become a structural constraint. The institution needed to support application traffic, secure inter site connectivity, user access, voice and collaboration services, and future digital growth, but it was doing so on a platform with too much architectural variation and too little policy consistency. That increased operational risk. It also made troubleshooting, scaling, and governance more difficult than they needed to be.
The North Africa context intensified the problem. A distributed footprint, variable carrier conditions, and a high premium on service continuity meant the client could not afford a design built around local optimisation or device level thinking. It needed a Cisco environment designed as one operating system, with clear treatment of resilience, segmentation, identity, and lifecycle manageability.
Our Approach
Qabas approached the assignment as an enterprise network architecture programme rather than a product selection exercise. The starting point was to define the target state across the key Cisco domains that would determine operational performance. This included campus core and distribution switching, branch and edge routing, firewall architecture, secure WAN design, wireless access, identity aware access control, and the management layer needed to govern the environment consistently.
The solution was structured around architectural coherence. Qabas designed the platform so that routing, switching, and security would operate as one system rather than as adjacent technical domains. Core failover, path resilience, segmentation boundaries, and security zoning were treated as primary design questions. This produced a more disciplined model for separating business critical traffic, administrative functions, user access, and sensitive operational services. The result was a Cisco environment with clearer trust boundaries and a more robust basis for policy enforcement across sites.
A further priority was resilience. Qabas designed the network to reduce dependence on single points of failure across the core, edge, and security layers. This included more deliberate treatment of redundancy, convergence behaviour, and service continuity under fault conditions. In a programme of this size, resilience cannot be added later. It has to be built into the architecture from the outset.
Qabas also focused on operational manageability. Large Cisco estates often become harder to govern as they become more capable. To avoid that, the design standardised topology, clarified control layers, and improved the basis for administration, monitoring, and lifecycle support. This was essential to ensuring that the platform would remain governable after deployment rather than simply impressive on paper.
Implementation
Qabas translated the architecture into a programme ready solution covering technical design, solution structure, and implementation sequencing. The work aligned the Cisco stack into an integrated enterprise platform spanning campus networking, site connectivity, security, wireless, and core services, while preserving architectural integrity at commercial and delivery level.
Execution planning was shaped around continuity. The objective was not only to define the target environment, but to provide the client with a realistic pathway for moving towards it without destabilising live operations. This allowed the programme to be assessed as an operating platform build rather than as a disconnected infrastructure procurement.
Results
The client obtained a materially stronger Cisco architecture for mission critical operations across North Africa. The new design improved segmentation, resilience, and administrative control while giving the institution a cleaner basis for scaling secure connectivity and digital services across its footprint.
Just as importantly, the programme converted a large capital commitment into a more defensible operating model. Instead of investing in premium equipment without sufficient architectural discipline, the client gained a coherent platform in which Cisco routing, switching, security, and access layers were designed to reinforce one another. That improved the quality of the investment and reduced the structural risk embedded in the previous environment.
This engagement showed Qabas’s ability to handle large scale Cisco infrastructure programmes at architecture level, where network design is not merely about connectivity, but about creating a resilient control layer for the wider institution.
