A10 Networks

A10 Networks (NYSE: ATEN) is a San Jose, California–headquartered application delivery and cybersecurity company founded in 2004 by Lee Chen. A10 builds the ACOS (Application Centric Operating System) software platform that powers its Thunder family of physical appliances, virtual machines (vThunder), and containerized form factors across hyperscalers and private clouds. The product line spans the Thunder ADC (Application Delivery Controller for L4–L7 server load balancing and GSLB), the Thunder TPS / A10 Defend portfolio (DDoS detection, mitigation, orchestration, and Threat Control SaaS) protecting service-provider and enterprise networks from volumetric and application-layer attacks, Thunder CGN (Carrier-Grade NAT and IPv4/IPv6 transition), Thunder CFW (consolidated firewall, VPN, CGN, and secure web gateway), SSL Insight for encrypted traffic decryption, the A10 Defend Next-Gen WAF (incorporating ThreatX), and the A10 AI Firewall for protecting LLM and AI application traffic. Every ACOS device exposes the aXAPI v3 — a RESTful HTTPS interface that is the primary configuration and operational control plane for the platform, supporting ACOS 4.0.0 through 7.0.2. The aXAPI surface is exhaustive (the official Terraform provider exposes 3,627 resources) and is wrapped by official Ansible collections (a10-acos-axapi, a10-acos-cli), a Python client (acos-client), the Thunder Kubernetes Connector (TKC, with 24 CRDs for pod-driven VIP automation), and integrations for OpenStack Octavia, Neutron LBaaS, AWS CloudFormation, Azure ARM, VMware vSphere, Helm, and Prometheus. A10 reported record annual revenue of $290.6M in FY2025 (up 11.0% year over year) under CEO Dhrupad Trivedi, serving 7,700+ customers across 117 countries.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/a10-networks: open an issue to ask a question, or submit a pull request to add artifacts.
