A10 Networks sells four main product lines: Thunder ADC for load balancing and application delivery, Thunder CGN for carrier-grade NAT and IPv6 migration, Thunder CFW as a consolidated security platform, and the A10 Defend family for DDoS detection and mitigation. In India the strongest fits are broadband ISPs short of IPv4 addresses and organisations running customer-facing applications that must stay up.

Where A10 fits, and where a normal firewall is enough
Most offices never need an A10 box. A branch firewall from Fortinet or Sophos already handles internet access, VPN and threat inspection. A10 enters when the problem is scale: thousands of subscribers sharing a pool of public IPv4 addresses, an application that must balance load across a server farm, or an internet link that must survive a large DDoS attack. Buy it for those jobs, not as an upgrade from an office firewall.
Carrier-grade NAT for Indian ISPs
Regional broadband operators in Tamil Nadu and Kerala often grow faster than their IPv4 allocation. Carrier-grade NAT lets many subscribers share public addresses while the network moves towards IPv6. Before sizing Thunder CGN, gather your concurrent subscriber count, peak throughput, session counts per subscriber, logging rules for lawful intercept, and how you will retain NAT logs. Logging is not optional for an Indian ISP, so plan the log store with the box.
Application delivery and DDoS: questions to answer first
- Which applications sit behind the load balancer, and how many servers each.
- Peak concurrent connections and SSL transactions per second, not just bandwidth.
- Whether you need active-active across two data centres.
- For DDoS: the size of your upstream links, whether your ISP already scrubs, and how fast you need detection to trigger mitigation.
