# Cerillion

> Cerillion is a global provider of BSS/OSS software for communications service providers. Its solutions support billing, charging, customer management, product management, service fulfilment and the monetisation of mobile, fixed, broadband, fibre, wholesale and digital services.

Cerillion follows a pure product model. All customers use the same core product software, which is configured to meet their individual business requirements rather than extensively customised. This common product approach simplifies implementation, maintenance and upgrades while reducing risk and total cost of ownership.

The Cerillion BSS/OSS Suite is the underlying modular and pre-integrated product suite. Cerillion Unify, Cerillion Enterprise, Cerillion Engage, Cerillion Metro and Cerillion Skyline use the same core software but are pre-configured and packaged for particular markets and business models.

The Cerillion platform is cloud-native, API-first and standards-based, with pre-integration across the suite. It supports TM Forum Open APIs and Open Digital Architecture (ODA), with embedded AI capabilities and support for Model Context Protocol (MCP) and Agent2Agent (A2A) communication.
