Before you trust a vendor with your network, you want proof that they have shipped the same pattern before. These are real engagements — the challenge the client faced, what we built together, and the result that mattered to the business. Names and exact figures stay marked until clients clear them, but the architecture and the thinking are the real part.
Every case study on this page follows the same structure so you can compare approaches across industries and draw the patterns that fit your own environment. Whether you are consolidating fragmented connectivity, moving communications to the cloud, or closing edge security gaps, you will find a reference that maps to your situation.
How a BFSI client unified fragmented MPLS and LTE/5G links under a managed SD-WAN with SASE, cutting downtime and accelerating branch rollout.
How a healthcare network migrated its contact centre to cloud unified communications, enabling remote clinicians and improving patient reach.
Every engagement we publish tells a story of a business that faced a concrete infrastructure problem and worked with Clevertek to solve it. What makes these studies valuable is not just the outcome — it is the reproducibility of the approach. When you read how a BFSI client consolidated fragmented MPLS and LTE/5G links under a managed SD-WAN with SASE, you are seeing a pattern that Clevertek can replicate in your environment with the same methodology.
We capture the metric that mattered to the business, not vanity numbers. Whether that is deployment time, downtime reduction, or the speed at which new users were brought online, the result is framed in the language of the buyer, not the vendor. Each engagement becomes a repeatable playbook that our teams reuse, refine, and improve with every new client.
If your situation looks similar to one you read here, that is not a coincidence — infrastructure challenges in banking, healthcare, retail, and manufacturing follow patterns. The right approach, applied once, becomes a template that delivers the same outcome with less friction the next time.
A case study is only worth reading if you can trace the decision behind it. Before anything is designed, we inventory what exists: which circuits terminate where, which applications depend on them, what the current contract actually promises, and which outages in the last twelve months caused business impact rather than annoyance. That inventory is what turns a generic architecture diagram into a plan for a specific estate, and it is also what lets a client challenge our assumptions with their own data.
Delivery is staged so the existing service keeps running until the replacement has proved itself. Each cutover has a defined window, a rollback path and a named owner on both sides. Where a site cannot tolerate a maintenance window, the migration is designed to run in parallel and the old path is retired only after the new one has held through normal business peaks, not just a quiet weekend.
After handover, the engagement moves into run mode under a single service level agreement covering every layer we took on: transport, security enforcement, cloud platforms, voice and collaboration. Service reviews run at a fixed cadence and cover incidents, changes, capacity against growth and the roadmap, so the conversation is about the next quarter rather than the last outage. That operating model is what makes the patterns below repeatable in a new environment.
These are the questions we hear most often when enterprise buyers evaluate whether a case study maps to their own situation — answered in plain language.
Engagements across BFSI, healthcare and other sectors — typically SD-WAN with SASE consolidation, cloud unified communications, and cross-domain network, cloud and security rollouts, structured as challenge, solution and measurable result.
Each study shows the outcome metric that mattered to the business, such as downtime reduction or faster branch rollout. Where a client has not yet authorised publication, figures are marked as placeholders rather than guessed.
Every study follows the same shape: the business challenge, the Clevertek solution, and the result that mattered — so you can take the pattern to a budget meeting even before the specifics are finalised.
The underlying patterns — consolidate fragmented links, move voice to cloud, close edge security gaps — repeat across sectors. If your situation is close, the relevant study is a fair starting point for a scoping conversation.

They come from Clevertek engagements in enterprise networking, cloud and unified communications. Some details are generalised and customer names withheld until publication is authorised, and that is stated wherever it applies.
Where a client has agreed to act as a reference, we arrange that during scoping rather than publishing contact details. Reference calls usually happen once the requirements are clear enough to be useful.
