  • SD-Branch

    SD-Branch is a software-defined branch networking architecture that unifies WAN, LAN, Wi-Fi, and security functions under centralized, policy-driven management. It matters for enterprises that need consistent control, security, and operations across many distributed branch or remote office locations.

  • SDN

    Software-defined networking (SDN) is a network architecture approach that centralizes control in software-based controllers, enabling programmable, policy-driven management of distributed network devices in data center, campus, and wide area environments for more consistent automation, segmentation, and security governance.

  • SDN Controller

    SDN controller is a software-based control plane component in software-defined networking that maintains a global network view, programs forwarding on SDN-enabled devices via southbound APIs, and exposes northbound APIs so applications and orchestration systems can implement policies and automate network operations.

  • SDN Northbound APIs

    SDN northbound APIs are programmatic interfaces that expose an SDN controller’s capabilities to external applications and orchestration systems, allowing enterprises to automate network policy, provisioning, and monitoring in alignment with application and service requirements across diverse environments.

  • SDN Orchestration

    SDN orchestration is the automated coordination and lifecycle management of software-defined networking services and resources across domains and controllers through centralized, policy-based control, supporting consistent service provisioning, change management, and alignment of network behavior with enterprise application and security requirements.

  • SDN Southbound APIs

    SDN southbound APIs are programmatic interfaces that link a software-defined networking controller to underlying forwarding devices, enabling centralized policy enforcement, automated flow programming, and controller-driven configuration of physical and virtual network elements in enterprise data center, campus, and WAN environments.

  • SDWAN

    SD-WAN (software-defined wide area networking) is a software-based WAN architecture that centralizes control, policies, and security for traffic across MPLS, Internet, and other links, enabling application-aware routing, encryption, and standardized management of connectivity among branches, data centers, and cloud services.

  • Sea Floor Observatory

    Sea floor observatory is a fixed or cabled installation on the seabed that hosts instruments for long-term monitoring of ocean, geological, and ecosystem processes, providing continuous data streams that feed scientific research, hazard monitoring, and environmental assessments relevant to infrastructure and policy.

  • Seamless Handover

    Seamless handover is a mobility process that keeps user sessions active while devices move between network cells or access points, with negligible interruption. It matters in enterprise networks because it supports continuous application use, roaming, and mobility-dependent workflows.

  • Search & Retrieval

    Search and retrieval is the process and technology stack that indexes, queries and returns information objects from structured and unstructured enterprise data collections, supporting relevance-ranked access that underpins knowledge discovery, regulatory response, customer service, analytics workflows and integrated application search experiences.

  • SecOps

    SecOps is a collaborative operating model and process framework that integrates information security with IT operations to coordinate threat detection, incident response, and remediation while maintaining availability, performance, and compliance of enterprise systems and services.

  • Secret Management

    Secret management is the process, tooling, and governance an enterprise uses to generate, store, control, and rotate credentials and other authentication data, reducing credential exposure risk and supporting consistent security and compliance across applications, infrastructure, and hybrid or multicloud environments.

  • Secure Access Module

    Secure Access Module is a tamper-resistant hardware component that stores cryptographic keys and performs authentication and access control functions for devices and networks, supporting secure key management, compliance requirements, and controlled credential lifecycle management in enterprise, telecom, payment, and IoT environments.

  • Secure Access Service Edge

    Secure Access Service Edge (SASE) is a cloud-delivered architecture that converges wide area networking and network security services into one model, enabling enterprises to apply consistent access, inspection, and policy controls for users, devices, and applications across distributed environments.

  • Secure Aggregation

    Secure aggregation is a cryptographic protocol that computes aggregate statistics over data from multiple parties while keeping each party’s individual inputs hidden, which supports privacy-preserving analytics and federated learning in regulated or sensitive enterprise data environments.

  • Secure Application Development Lifecycle

    Secure application development lifecycle is a structured process that embeds defined security practices into each phase of software development, enabling enterprises to manage software risk, support compliance requirements, and coordinate security activities across development, operations, and governance functions.

  • secure at inception

    Secure at inception is an approach in which organizations embed security requirements, controls, and assurance activities from the earliest concept and design stages of systems and platforms, supporting regulatory compliance, risk management, and reduced remediation costs across the technology lifecycle.

  • Secure Attestation Channel

    Secure attestation channel is a protected communication path that transports integrity measurements and related evidence between an attesting device and a verifier, enabling enterprises to validate hardware and software trust before granting access to systems, data, or cryptographic operations.

  • Secure Authentication Framework

    Secure authentication framework is a structured set of standards-based mechanisms, protocols, and policies that govern how enterprises verify identities and control access to systems and data, supporting strong authentication, centralized policy enforcement, and compliance with security and regulatory requirements.

  • Secure Avionics Network

    Secure avionics network refers to interconnected aircraft and supporting ground systems that protect flight-critical and mission-supporting electronics, data, and communications with cybersecurity and safety controls, enabling compliant, resilient airline and aerospace operations and supporting secure delivery of digital services across air and ground domains.
