Featured Reviews

GANESAN K - PeerSpot reviewer
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.
