Valuable Features

F5 BIG-IP LTM excels in load balancing, security, and customization, enhancing performance and reliability for complex network environments.
Fortinet FortiADC offers features like SSL offloading and load balancing, valued for simplicity, scalability, affordability, and integration.
Fortinet FortiWeb provides advanced security features and seamless integration, offering cost-effective, robust protection and easy deployment for enterprises.
The impact of SSL offloading on reducing server load and latency is very much positive because whatever traffic we receive, we encrypt at our F5 BIG-IP Local Traffic Manager (LTM) level, which has definitely reduced the additional load and SSL decryption load on the servers, so it has very much helped us and it is very smooth; it will not take much time and will not impact our regular traffic.
Project Manager at IBM
R-series has better CPU and memory, leading to higher throughput with minimal downtime, making it a significant improvement over the I-series.

Network Engineer at Stryker
Load balancing has improved traffic distribution and currently supports high availability upgrades
F5 BIG-IP Local Traffic Manager (LTM) offers effective load balancing methods that help distribute traffic across our servers, whether we have two or several. This load balancing feature stands out as it is the fundamental work we do with F5 BIG-IP Local Traffic Manager (LTM). While I recognize there are many features, such as iRules, which I have not explored yet, we primarily work on VIPs, pool members, and traffic distribution. The load balancing algorithms' flexibility makes them very useful for our team, enabling us to choose different servers and manage load effectively. We use various methods based on user or application requirements, making the algorithms set up by F5 in the backend quite helpful. F5 BIG-IP Local Traffic Manager (LTM) positively impacts our organization primarily through its load balancing capabilities. We avoid traffic overload on individual servers by placing backend servers behind F5 BIG-IP Local Traffic Manager (LTM) VIP. This load balancing helps us manage traffic effectively. Since the configuration of the I-series, we have had smooth performance, and with the recent migration to the R-series, it is working faster than before, providing positive outcomes for our operations. Since moving to the R-series, I notice improved performance; it is user-friendly and handles traffic efficiently. The upgrading process is different as we create tenants and a main host. R-series has better CPU and memory, leading to higher throughput with minimal downtime, making it a significant improvement over the I-series.

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.

Security threats have been reduced through seamless deployment and strong integration with other tools
I have used Fortinet FortiWeb's integration features. We have easily integrated all of the applications with the product. Most of the applications we are using are in-house built. My technical team is looking after the best features. I have not used it extensively for maybe two and a half years. I have been involved in the installation, but I am not actually using the product. I work with it from time to time but not extensively. I would assess Fortinet FortiWeb's adaptive machine learning and artificial intelligence as having new patches installed regarding artificial intelligence, but when we bought it, I think the learning feature was there. Now they have installed artificial intelligence features through patches. We have a complete portfolio of Fortinet in our organization, including FortiMail, Fortinet FortiWeb, and FortiGate, along with multi-factor authentication. All of the products are from Fortinet. Fortinet tools integrate with each other and work in conjunction. I think Fortinet FortiWeb has helped us meet regulatory compliance because we are not a regulatory organization, but our sister organization is regulatory. We have regulatory compliance with the International Civil Aviation Authority, whose audit teams have checked our data center and these security products, and they are satisfied with us. The question about leveraging Fortinet FortiWeb's automated policy management does not pertain to my domain because I am not so technical, but I am in a management role now. My engineer is more technical than me. I would rate this product an eight point five out of ten.
