Operations and sourcing

- 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.
