More About Big Network
Big Network focuses on SDN and secure connectivity for organizations that operate across multiple sites, data centers, and cloud environments. Its offerings are structured as cloud-managed services that abstract the underlying transport and provide a unified way to connect users, devices, and applications over public and private networks.
The company’s platform is typically positioned as a VPN replacement (network security) and as an overlay networking solution (networking) that can be deployed without extensive changes to existing underlay infrastructure. Enterprises use it to establish encrypted tunnels between endpoints, branch locations, and cloud workloads, with access governed by centralized identity and policy rather than static network constructs alone.
Big Network’s architecture follows common SDN patterns, with a cloud-hosted control plane managing distributed data-plane components deployed as software clients, virtual appliances, or on-premises (on-prem) gateways. The control plane handles configuration, routing policies, authentication, and authorization, while data-plane components forward traffic using encrypted tunnels over IP networks. This separation of control and data planes enables centralized orchestration and monitoring across heterogeneous environments.
The platform is typically delivered through a web-based management console (network management) that provides policy definition, device and user enrollment, key and certificate management, and observability features such as connection status and basic telemetry. Identity and access control functions are often integrated with enterprise directory services or identity providers, enabling role-based or user-based network access policies that align with zero trust networking concepts.
From a protocol and technology perspective, Big Network uses standard IP networking and common encryption approaches for secure tunnels. While specific protocol choices can vary by deployment, the approach aligns with contemporary secure overlay networking practices, such as establishing mutual authentication between endpoints, enforcing least-privilege access to resources, and encapsulating traffic over existing internet or Wide Area Network (WAN) links.
In the enterprise IT marketplace, Big Network fits within categories such as software-defined perimeter (network security), secure remote access (network security), and SD-WAN-like overlay networking (networking), depending on how customers deploy and integrate the platform. Organizations may use it alongside traditional firewalls, Software-Defined Wide Area Network (SD-WAN) appliances, and identity and access management systems as an additional overlay for secure connectivity and policy-based access.
For directory and taxonomy purposes, Big Network can be positioned under secure networking and connectivity services, with subcategories including VPN replacement, zero trust-aligned remote access, and cloud-managed SDN overlays for multi-site and multi-cloud environments.
