Executive SummaryUpdated on Dec 17, 2024

A10 Networks Thunder ADC and Fortinet FortiADC are key players in the application delivery controller market. A10 Networks Thunder ADC holds an edge due to its all-inclusive licensing scheme, providing cost-effective solutions and operational efficiencies.

Features: A10 Networks Thunder ADC includes IPv6 support, advanced DDoS mitigation, and SSL offloading, offered under an all-inclusive license which simplifies budgeting. Additionally, Global Server Load Balancing enhances scalable site management. Fortinet FortiADC exhibits strengths in its robust SSL offloading and DNS load balancing, ensuring redundancy and flexibility across varied environments.

Room for Improvement: A10 Networks Thunder ADC can improve its graphical user interface usability and expand third-party integrations. Users note legal concerns and express a desire for enhanced mobile web acceleration and cloud integration. Fortinet FortiADC faces challenges with configuration complexity and infrequent updates. It lacks built-in advanced security features, often requiring additional purchases that affect cost efficiency.

Ease of Deployment and Customer Service: Both A10 Networks Thunder ADC and Fortinet FortiADC primarily support on-premises deployment.

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.

GANESAN K

Has supported load balancing for medical applications and could benefit from more custom configuration options

Some customers need custom management for handling their applications across the servers. Instead of having a predefined solution, if we had space for custom-based algorithms to load balance the traffic, it would be better. We have faced such cases with A10, where we can leverage many custom scripts and do much more. Even though A10 primarily focuses on SMBs, they have also ventured into the enterprise market. Fortinet has been a pioneer for enterprise solutions, such as firewalls, SASE, ZTNA, and SD-WAN solutions, and they are in a leader quadrant. Therefore, they should have more options. From a pricing perspective, it is expensive.
