Featured Reviews

Bonieber  Orofeo - PeerSpot reviewer
IT Manager at Chong Hua Hospital
Identifying compromised traffic and securing data has been a significant advantage
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) is its ability to identify compromised traffic and its capabilities in authentication. Additionally, the security aspect of it provides a significant advantage as it helps us secure our data, which is a major investment and benefit for us. Before using this system, we had difficulties in storing our data and managing the traffic that comes in and out.
GANESAN K - PeerSpot reviewer
Senior Technical Engineer at Safezone Secure Solutions Private Limited
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.
