More About Proximus
Proximus operates as an integrated telecommunications and ICT provider in Belgium with activities that extend into international markets through its enterprise and wholesale divisions. For enterprise, government, and institutional customers, Proximus supplies end-to-end connectivity, IT infrastructure, and managed services that can be aligned with multi-site, hybrid, or cloud-based architectures. The group’s portfolio spans fixed broadband, mobile, and converged access, combined with Wide Area Network (WAN) and Local Area Network (LAN) services that support corporate networks and branch connectivity.
In the enterprise segment, Proximus positions its offerings around managed networking (network infrastructure), cloud services (cloud infrastructure), cybersecurity (security), unified communications and collaboration (UC&C), and application-enabling platforms. Its networking services commonly integrate technologies such as Multiprotocol Label Switching (MPLS), Ethernet, Virtual Private Network (VPN), SD-WAN-style architectures, and Wi‑Fi solutions, designed for integration with customers’ existing data center and cloud environments. Proximus also provides Session Initiation Protocol (SIP) and IP-based voice services aligned with Voice Over Internet Protocol (VoIP) standards and interconnects with its mobile and fixed telephony networks.
Proximus’ cloud and data center offerings (cloud infrastructure, hosting) address scenarios where customers deploy workloads in private, public, or hybrid cloud models. These services typically include hosting, virtualized compute and storage, backup, Disaster Recovery (DR), and connectivity to hyperscale cloud platforms. Proximus combines these with managed services, monitoring, and Service Level Agreements (SLAs) that allow enterprises to offload day-to-day operations for core infrastructure components.
The company’s security services (security) span network security, endpoint and email protection, identity and access control, and security monitoring. Proximus also develops and operates IoT and data platforms (IoT platforms, data services) that enable device connectivity, data collection, and analytics-driven applications for sectors such as utilities, smart cities, logistics, and industrial environments. These platforms rely on standard protocols and technologies used in IoT and Machine-to-Machine Communication (M2M) communication, and integrate with Proximus’ mobile and fixed networks.
In the wholesale and international carrier domain (carrier services), Proximus offers capacity, voice termination, roaming, and IP transit over its domestic and international infrastructure. This positions Proximus within marketplace categories including connectivity and access, enterprise networking, cloud and hosting, managed security, unified communications, IoT platforms, and carrier and wholesale services. For enterprise technical stakeholders, Proximus functions as a single provider that combines network infrastructure, ICT services, and platform capabilities under one umbrella, designed to integrate with broader multi-vendor architectures and governance frameworks.
