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

"I like the solution's load balance with DNS intelligence."

"Content caching and content compression are good features."

"Customer service is excellent."

"The most valuable feature is the SSL offloading capacity; it is easy to manage and easy to configure."

"Fortinet FortiADC is a good product because each and every piece of content is monitored by it."

"TSL and SSL offloading are both very good features."

"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."

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

More Fortinet FortiADC pros

"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."

"Packet inspection has been effective for mitigating DDoS attacks."

"We have researched them all, and it's a good solution all around."

"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."

"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."

More Fortinet FortiDDoS pros

Cons

"Technical support and documentation could both be improved."

"If I need design help, they do not assist; they say it is a design issue they cannot support, and I must approach the system integrator."

"The initial setup could be simplified."

"The product’s price could be reduced. Also, some of its features need to be more advanced."

"There is a mismatch between the number of features they are offering and the device capacity on how much it can handle."

"FortiADC is complex to configure so the interface should be improved."

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

"The L7 Persistent load-balancing algorithm has not worked for me after having tested it many times with my customer's in-house application."

More Fortinet FortiADC cons

"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."

"I would like to see analytics, big data."

"Alerts and reporting features must be improved."

"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."

"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."

"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."

"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."

More Fortinet FortiDDoS cons

Pricing and Cost Advice

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

"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.
