Efficient application security while optimizing connections

The initial setup is simple; it is not complex. The configuration itself is simple and can be done in a couple of hours. However, the migration of the system to A10 Networks takes longer due to critical applications. Clients prefer to move them one by one, which is why it takes a significant amount of time. The configuration itself is simple, especially for this application.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."

"Our clients appreciate that this is a security enabled solution."

"What I like about Lightning ADC, is that instead of having a big appliance sitting in front of the Kubernetes cluster, Lightning can pretty much go inside of Kubernetes."

"It helps with defining server load balancing tasks and managing SSL certificates, ensuring the communication flow through the Fortinet gateway."

"Ease of use in deploying and having it up and running requires minimal knowledge."

"The main feature that we use is GSLB (Global Server Load Balancing). GSLB makes the customer's network more reliable by scaling applications across multiple datacenters. GSLB as a disaster recovery solution can direct traffic based on site availability."

"Ultimately, Fortinet constructs every solution needed for each defense layer, making it comparatively better than Trellix, Trend Micro, or SentinelOne."

"We can do patches offline without causing customers outages. The web application firewall features, especially those related to the OWASP Top Ten, provide automated protections. This allows more flexibility in patching the backend applications. Additionally, it offers visibility into the requests being made to the applications, and you can't protect what you can't see."

"The most valuable feature is the SSL offloading capacity."

"It's a good product because it supports all the features that ADC solutions in the market can support, like F5 solutions, for example, such as the LTM of F5."

"Although FortiADC has multiple features that I like, the global DNS is the most helpful. It is primarily useful for customers with huge environments and at least two data centers. FortiADC can act as your DNS server. It can check which data center has the lowest latency, and route traffic to that one. It's an intelligent DNS."

More Fortinet FortiADC pros

Cons

"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."

"A10 documentation is not as open and accessible as AWS and Azure documentation is."

"The support from A10 should be improved."

"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."

"The solution needs to integrate sFlow. sFlow provides better visualization of the bandwidth and types of traffic passing through the device. When used in the traffic path, this information can be really useful."

"The solution's WAF needs an upgrade because it is not as good as FortiWeb, VMware, F5, or Imperva."

"Because it is so generic, the documentation requires special attention. A person who has not worked on Fortinet FortiADC or a similar product will struggle to understand what the document is trying to say. The documentation could be more specific, and more detailed."

"Issues with SSL and encrypted traffic."

"Technical support and documentation could both be improved."

"Though FortiADC is useful, I'd appreciate more user-friendly features and in-depth insights into network activity, like detailed logs and AI-driven feedback for optimization."

"The solution should improve finding false positives and false negatives. There are a lot of false positives."

Pricing and Cost Advice

Information not available

"The price is competitive"

"Compared to F5, FortiADC pricing is better."

"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."

"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."

"The solution's pricing is an issue and should be improved."

"I believe the price is good. It's fair. There are no extra costs."

"The product has affordable pricing."

"The product has average pricing. I rate its pricing a five out of ten."

Is Citrix ADC (formerly Netscaler) the best ADC to use and if not why?

For ADC, any ADC can do a good job. But in case if you want to add WAF functionality to the same ADC hardware you have to look for other ADC's like F5, Imperva, Radware, Fortinet, etc.
