Our response to industry-specific problems

Nos clients du secteur Banque Finance : MFEX, CNP Assurances, Edenred, Société Générale

Banking, Finance, Insurance and Payment Instruments

In recent years, the Banking, Finance, Insurance, and Payment Services sector has experienced a significant structural transformation of its activities, mainly due to the rapid acceleration of the digitalization of customer practices and the regulatory framework.

Today, the sector must rethink its approach to product design and delivery: security concerns, system impermeability, and the multiplicity of stakeholders/partners in the value chain require cutting-edge expertise to capitalize on the opportunities presented by cloud components (API first, containerization, platform hardening, etc.) and the business levers represented by data.
Nos clients du secteur Industrie : Nexans, Invivo, Guez, Vinci

Industry, Manufacturing, and Utilities

The industry, manufacturing, and utilities (gas, water, electricity, and construction) sectors have historically been slow to start their digital transformation. Today, they are looking to benefit from the ROI of the cloud while considering the complexity of the existing situation and the need to establish a governance framework that can service subsidiaries of varied sizes. Issues concerning the use of their data also concern them.

Many companies in these sectors have started Digital Factory and Cloud Center of Excellence (COE) initiatives to provide a new set of services. Cellenza provides customized support, taking into account the maturity level of their teams and promoting the transfer of skills to make them autonomous.
Nos clients du secteur Medias et Télécoms : Publicis, A2MC1, TF1, LFP

Media and telecoms

The French telecoms market currently has limited connectivity services. As a result, it faces significant transformation challenges in finding new growth drivers, particularly in developing the Internet of Things (IoT), implementing new digital services, and adopting digital transformation to optimize its time-to-market.

Information technology and telecommunications are converging into a single entity (digitization of telecommunications, centralized control, communications security, performance, and availability). Cellenza shares its expertise in these highly technological areas by providing customized support tailored to the issues and challenges faced by this sector.
Client de l'industrie pharmaceutique : Cerballiance

Pharmaceuticals and healthcare

The healthcare sector relies on IT resources to streamline care operations, process data, and deliver online applications and portals. Following the rapid increase in activity associated with COVID, the healthcare sector must accelerate its digital transformation, including initiatives for cloud migration, artificial intelligence development, and application development using modern technologies…

This sector is also subject to strict regulatory requirements, particularly with regard to security and data protection. Cellenza’s healthcare expertise includes the cloud, data, legal, and software development.
Nos clients du secteur des Services : KPMG, Capgemini, Sopra Steria

Services

The services sector faces a significant time-to-market challenge. Service providers and ISVs must undergo a digital transformation to the Cloud to maximize time-to-market and expand their commercial footprints. The goal is to get their products to market as quickly as possible to meet customer expectations.

Cellenza, a Microsoft technology expert, uses its extensive knowledge to help service companies digitally transform to become more competitive.
Nos clients du secteur Retail et Luxe : Cdiscount, LVMH, Chanel, Franprix

Retail and luxury

The largest companies in the retail industry have a size-related problem: Because of the number of locations, each company’s IT department develops its own applications and APIs. Cellenza applies its expertise to enable these assets to be shared across IT departments through identifying, classifying, and using APIs.

With its API Strategy offering, Cellenza can harmonize application strategy across the group. Retail is also heavily focused on developing use cases with connected objects. This requires knowledge of cloud and IoT infrastructure. Finally, given the massive amount of data produced in this industry, maximizing the value of that data by creating connections that benefit the business is critical.

Mobility and transportation

Many players in the transport sector have organization of vital importance (OVI) status. As a result, they face two major issues when selecting their cloud technologies: high security and compliance with cloud providers’ CSR policies. The transportation sector must ensure critical continuity of service. That’s why it needs experts who are proficient in the latest technologies.

The mobility sector is also subject to strict data-related constraints. It must be able to ensure data storage, use, and traceability in accordance with the requirements of its OVI status. Cellenza supports major players in the transportation industry in the areas of cloud and data/IA.
