More About ONI
ONI operates as a business-focused Information and Communication Technology (ICT) and telecommunications provider in Portugal, delivering network, cloud, and managed services aimed at corporate, wholesale, and public-sector organizations. Its portfolio addresses connectivity, compute, storage, security, and collaboration requirements that are typically present in multi-site enterprises, service providers, and institutions with regulated or availability-sensitive workloads.
In connectivity, ONI provides IP-based networking over fiber and other access technologies, offering services such as Ethernet, Multiprotocol Label Switching (MPLS) VPN, internet access, and interconnection solutions for data centers and branch locations (network services). These services are used to build private WANs, connect to cloud environments, and integrate remote offices with central IT resources. Architectures often rely on MPLS for Traffic Engineering (TE) and Quality of Service (QoS), IP routing protocols for resilience, and, where applicable, SD-WAN overlay technologies for application-aware routing and centralized policy control.
ONI’s cloud and data center services (cloud infrastructure and hosting) give enterprises options for infrastructure as a service, virtualized compute, storage, and backup hosted in ONI-operated facilities. These services typically use virtualization platforms, standard x86 server architectures, and enterprise storage systems, along with network segmentation and firewalls to maintain tenant separation. Customers may use ONI cloud resources as a primary hosting location, a Disaster Recovery (DR) site, or a hybrid extension to on-premises (on-prem) data centers, connecting through VPNs or dedicated links.
In managed security and network services, ONI provides perimeter firewalls, intrusion detection and prevention, secure VPN access, and monitoring (security services). These offerings rely on established security frameworks and protocols, including IPsec and SSL/TLS for encrypted communications and centralized logging and alerting for operations teams. Enterprises use these services to enforce corporate security policies and to offload routine operational tasks such as patching, configuration management, and incident handling.
ONI also offers unified communications and collaboration services (UC and collaboration), including IP telephony, Session Initiation Protocol (SIP) trunking, corporate voice platforms, and contact center solutions. These services use Voice Over Internet Protocol (VoIP) protocols such as SIP and Real-time Transport Protocol (RTP), integrate with PBX systems and CRM platforms, and can be delivered from ONI’s infrastructure or deployed on customer premises with managed support. This supports call routing, numbering plans, and integration with collaboration tools and mobile endpoints.
Within an enterprise technology directory, ONI aligns to categories such as enterprise and wholesale connectivity, cloud infrastructure and hosting, managed network and security services, and unified communications and collaboration. Its role spans both carrier-style network provisioning and IT service outsourcing, providing organizations with a single provider for Wide Area Network (WAN), data center, voice, and managed support functions.
