A10 Networks, Inc.

What the company does

A10 Networks provides secure application and network infrastructure solutions for enterprises and service providers. Its products support on-premises, hybrid cloud, and distributed environments and are designed to deliver high performance, reliability, and protection for digital services.

Core offerings include:

  • Centralized management and policy enforcement

All offerings are built on the ACOS software architecture, which supports physical, virtual, containerized, and cloud-native deployments and provides consistent performance and security policies across environments.

Pricing and licensing models include perpetual and term licenses, subscriptions, pay-as-you-go, and consumption-based arrangements.

Three core solution areas

  1. Legacy Networking — Carrier-grade traffic processing for service provider and enterprise networks (carrier-grade NAT, high-scale session management, policy controls, visibility).
  2. Next-Generation Networking — Application delivery and traffic management for modern data centers, hybrid cloud, and distributed architectures (server load balancing, high availability, SSL/TLS offload, global load distribution, application-level observability).
  3. Network Security (A10 Defend) — Integrated security across the portfolio and dedicated WAAP capabilities (DDoS protection, web application and API protection, bot protection, threat intelligence, orchestration/automation).

Operations and sourcing

  • Manufacturing is outsourced to primary manufacturers including Lanner Electronics (Taiwan), AEWIN Technologies (Taiwan), and iBase. Manufacturing agreements use short initial terms with automatic annual renewals and do not include long-term capacity guarantees.
  • Inventory and supply: Some components are sourced from sole or limited suppliers and can have lengthy lead times. Dependence on external manufacturers can affect delivery timing and costs.
  • Open source and software: The company uses open source software (for example, the Linux kernel) under internal policies and manages open source licenses.

Services and support

  • Revenue includes product sales plus maintenance and support contracts.
  • Support centers provide global coverage and tiered service offerings.
  • Renewal of maintenance and support contracts is an important element of recurring revenue.

Strategic position

A10 focuses on delivering integrated application delivery, security, and traffic management within a single architecture to reduce operational complexity for customers deploying hybrid, multi-cloud, and AI-enabled workloads. The company competes across ADC, cloud-based security, WAAP, DDoS protection, and API security markets, and aims to grow recurring revenue through subscriptions and software-focused offerings.
