Head Of Technical And Network Security at Connex Information Technologies
Global load balancing has improved reliability and currently reduces latency across multi-cloud
I have experience with AWS, and I also have experience with both AWS and Azure, and sometimes GCP as well. We utilize multi-cloud support with A10 Networks Thunder ADC. We have customers utilizing A10 Networks Thunder ADC in the public cloud as well. I didn't technically involve myself with analytics in A10 Networks Thunder ADC because I haven't been involved in that part in the past few years. According to my team, the analytics tools are quite prominent, so there are no issues there. We have a distributorship with A10 Networks and are considered a partner. I would rate this review 9 out of 10.

Displays flexible, user-friendly interface with minor licensing challenges
The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management
