More About
Master Link operates as a network and communications services provider focused on the Brazilian enterprise market, addressing connectivity, managed services, and unified communications requirements for organizations that run distributed operations across multiple sites or regions.
The company’s connectivity portfolio commonly includes MPLS services (enterprise networking), site-to-site virtual private networks (VPNs) (network security), and dedicated internet access (business connectivity), which are used by enterprises to link branch offices, headquarters, data centers, and cloud environments with predictable performance and controlled Quality of Service (QoS) for critical applications.
On top of transport services, Master Link delivers managed network infrastructure services (managed IT services), typically spanning configuration, monitoring, and troubleshooting of routers, switches, and customer edge equipment, which allows IT teams in client organizations to centralize network operations and rely on contracted service levels instead of managing all network components in-house.
In unified communications, the company supports corporate telephony and contact center workloads (unified communications), integrating voice over IP (VoIP), SIP-based trunks, and PBX or IP-PBX systems to connect branch offices and remote workers, and to route inbound and outbound customer calls through consistent numbering plans and call handling policies.
Master Link also provides data center and hosting services (data center services) for business applications and systems that require stable network proximity, combining colocation or hosted infrastructure with its own connectivity footprint to support latency-sensitive or bandwidth-intensive workloads, and to interconnect on-premises (on-prem) environments with hosted resources.
Security services (network security) are generally integrated at the network perimeter and service edge, including managed firewalls, intrusion control features, and traffic segmentation across VPNs or VLANs, giving enterprise customers a way to align connectivity projects with basic security and compliance requirements without deploying and administering all security appliances directly.
In an enterprise IT and telecom marketplace directory, Master Link fits into categories such as enterprise connectivity services, managed network services, unified communications and telephony, data center and hosting services, and network security, serving organizations that need outsourced or co-managed connectivity and communication infrastructure in Brazil.
