More About Masergy
Masergy provides managed Software Defined Networking (SDN) and security services for enterprises that operate distributed networks and use cloud applications. Its core focus is on Software-Defined Wide Area Network (SD-WAN) (networking) and secure connectivity services that link data centers, branch offices, remote users, and cloud platforms over a combination of private and public networks. Masergy positions its services for organizations that require predictable performance for real-time and business-critical applications while managing cost and complexity across global WAN environments.
The company’s SD-WAN (networking) solutions typically use overlay architectures that separate the control plane from the data plane, enabling centralized policy management and dynamic path selection across Multiprotocol Label Switching (MPLS), broadband internet, and other transport types. Masergy uses common SD-WAN capabilities such as application-aware routing, bandwidth aggregation, traffic prioritization, and link resiliency. These services are delivered as managed offerings, with Masergy providing configuration, monitoring, and lifecycle operations through management portals and service-level commitments.
In security, Masergy delivers managed security and secure access offerings that align with enterprise network security requirements (network security). These can include next-generation firewalling, intrusion detection and prevention, secure web access, and threat monitoring delivered from cloud-based platforms and Security Operations (SecOps) centers. Masergy’s portfolio supports architectures associated with Secure Access Service Edge (SASE) (SASE / secure networking), combining SD-WAN features with security controls that are enforced close to users and applications. This allows organizations to define policies centrally and apply them consistently across branches, remote users, and cloud resources.
Masergy’s services are used in enterprise environments where IT teams seek to standardize WAN and SecOps across multiple regions and connectivity types. The company provides global private backbone options, internet-based connectivity, and cloud on-ramps, with monitoring and analytics tools for visibility into application performance and network health. Protocols and technologies commonly associated with Masergy’s offerings include IPsec VPNs, routing protocols for WAN edge integration, and various encryption and tunneling methods used in SD-WAN overlays.
Within an enterprise technology directory, Masergy aligns to categories such as SD-WAN services (networking), managed network services (managed services), Managed Security Services (MSS) (network security), and SASE-aligned secure networking services (SASE / secure networking). Its role is to provide managed connectivity and security capabilities that System Integration Testing (SIT) between customer sites, user endpoints, and cloud workloads, enabling network and security teams to operate a unified WAN and security posture through managed service constructs.
