RONALDO DE MELO - PeerSpot reviewer
Sales Account Executive at l8
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.
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.

Quotes from Members

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

Pros

"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."
"Our clients have reported an increase in revenue by around 5% on a year to year basis, since this solution was implemented."
"Our clients appreciate that this is a security enabled solution."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"The GSLB, the DR side, is the best part. Because we had our main side in one city, we created another, and we had a complete MPLS over the internet. We used the GSLB and data loss for our business applications."
"I like all the products in the Fortinet family, they are simple to use and you can integrate a virtual server in a couple of minutes."
"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."
"Customer service is excellent."
"Ultimately, Fortinet constructs every solution needed for each defense layer, making it comparatively better than Trellix, Trend Micro, or SentinelOne."
"The solution is less expensive than F5 or Imperva and is the most reasonably priced option available."
"My experience with Fortinet has been very positive."
"FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms."
 

Cons

"The support from A10 should be improved."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"The documentation is pretty much closed and I think A10 crashes sometimes because initially, I was not able to set up Lightning ADC."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"The L7 Persistent load-balancing algorithm has not worked for me after having tested it many times with my customer's in-house application. I'd like to suggest that the company make sure that all load-balancing algorithms work properly with most applications, even those that are in-house apps."
"The initial setup was not complex, but it was not simple either."
"The WAF function implementation would be better if we could do it very easily and in a user-friendly way."
"My main complaint is that the WAP functionality is very primitive."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"Fortinet has some drawbacks, and it can be a bit challenging to scale."
"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."
"I think it would be helpful if Fortinet put more video examples on their cookbook site."

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.
Do you recommend Fortinet FortiADC?
I recommend Fortinet FortiADC. My experience with Fortinet has been very positive. Our company has been using it for around five years. We mainly use FortiADC for the load balancing of application ...
What is your experience regarding pricing and costs for Fortinet FortiADC?
Pricing is not considered on our side since we are the implementation team. Our pre-sales team considers the pricing and all the details.
