01 2026Infrastructure Renewal
A highly available storage infrastructure with no service interruptions
Une entreprise qui tourne 24 heures sur 24, 365 jours par an : <em>l'ancienne infrastructure devait être remplacée sans jamais s'arrêter</em>. La nouvelle a donc été montée en parallèle, et les machines virtuelles migrées une à une.

02 2026Design and Development
Design and Development of a Microsoft Telephony Management Platform Teams
There was no off-the-shelf solution on the market for managing multiple operators, multiple sites, and multiple tenants in a consistent manner. We didn't look for a product—we designed one ourselves and then integrated it into our existing IT system.

03 2026Migration infrastructure
Migration from on-premise servers to Microsoft Azure

05 2024Application Redesign
CRM , and AI Project: Revolutionizing Customer Management for a Financial Services Company
Customer data scattered across multiple systems, fragmented sales and support processes: a 360° view first, then AI. If done in the opposite order, automation would have institutionalized the chaos.

None of the published case studies mention . Our services cover much more than what is published here—audits, consulting, and support contracts are not included. Tell us about your situation, and we’ll let you know if we’ve handled a similar case before.
Some of our cases are not made public.
A project sheet documents an implementation, with a beginning and an end. Three of our activities do not fit this format: they are measured in contract years, in hardware and licenses delivered, or in studies submitted—not in completed projects.
Shipped worldwide, though not necessarily together.
We don’t just sell hours. We also supply the hardware we install—along with the licenses that go with it, or without it: a Microsoft license can easily be ordered on its own. We work with you to determine the right specifications, configure the equipment, and then ship it to your locations—including outside Switzerland, for organizations whose operations are also based abroad.
- Servers, storage, hyperconvergence, backup, and workstations — Dell Technologies, Veeam
- Telephony, gateways, and terminals — AudioCodes, Ribbon, Poly , and others
- Licenses Microsoft 365, Azure and Dynamics 365, with or without the hardware
- Sizing, configuration, commissioning, and international delivery
Contracts that last for years.
Level 3 in our areas of expertise, Level 2 in certain technologies. Taking over an environment that no one else understands is part of our day-to-day work—in fact, it’s often what brings us to a client’s site before any project even begins.
- Level 2 and Level 3 Support
- After deployment, including in environments that we did not build ourselves
- Temporary Staffing — Lambert Consulting has been authorized LSE since 2018
The work that defines the project.
Architectural planning, feasibility studies, and second opinions on ongoing projects: these tasks don’t result in a project proposal, but they are what determine whether the rest of the project will succeed. Design studies and audits are part of the scope of work.
- Audit of an Existing Environment
- Feasibility Study Prior to Decision-Making
- Architectural Design: Fixed-Price or Time-and-Materials Billing
Is there a case similar to yours?
Describe your environment in a few lines. We’ll let you know what similar projects we’ve handled before and how we could assist you: on a fixed-price basis, on a time-and-materials basis, or through post-launch support.
We'll respond within 24 business hours. Your request is sent to the sales team at Renens —and nowhere else.
