Featured Reviews

OusaidAbaz - PeerSpot reviewer
Integrates load balancing efficiently within existing technology environments
FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms. It allows for the creation of virtual IPs and applying various algorithms for traffic management. Although it offers fewer algorithms than competing platforms like F5, its capability to manage load balancing makes it valuable. The security features depend on the environment, relying on firewalls like FortiGate.
PeterForster - PeerSpot reviewer
A highly stable and scalable load-balancing software that offers great technical support
My company is really happy with Kemp LoadMaster as a product. My company is also happy with the support we receive from Kemp LoadMaster. I want Kemp LoadMaster to provide users with better reporting capabilities in relation to TCP packets. In general, the connections that are present in the system require improvement. Feature-wise, Kemp LoadMaster has everything that our company's customers require. Kemp LoadMaster also has features that have supported our company's past projects.

Quotes from Members

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

Pros

"Content caching and content compression are good features."
"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."
"The solution enhances performance by efficiently balancing the load across multiple backend servers."
"I am impressed with the product's load-balancing feature."
"Customer service is excellent."
"The solution provides high-level services such as availability, redundancy, and load balancing between servers."
"Simple to use and easy to integrate."
"Fortinet FortiADC is a good product because each and every piece of content is monitored by it."
"The most valuable features for us are the Load Balancing and Web Application Firewall, as we have a lot of web applications."
"The most valuable feature that I found is the load balancing feature, it is the core function of the product."
"Scalability-wise, I rate the solution a ten out of ten...I rate the technical support a ten out of ten...The initial setup of Kemp LoadMaster is very simple."
"LoadMaster is easy to deploy and understand."
"We really like the performance of this solution."
"The feature I find most valuable is load balancing with different algorithms."
"Using Kemp as a front-facing service appliance, it allows me to have the flexibility of swapping out real servers behind the scenes without any intervention from my network team."
"There is a simplicity to the setup and configuration."
 

Cons

"I had a terrible experience with Fortinet support. I only used support once when I bought the solution. I got no response for two days. However, I believe that it's no longer the case. Fortinet solutions have problems when they're launched. For example, we had issues with Fortinet's authenticator when it came out. We also had trouble with FortiNAC in the beginning."
"The solution's WAF needs an upgrade because it is not as good as FortiWeb, VMware, F5, or Imperva."
"There is a mismatch between the number of features they are offering and the device capacity on how much it can handle."
"The solution’s pricing could be improved."
"One of the product's areas of improvement includes reducing the number of components requiring additional licenses, such as antivirus and IDS, which are already covered by our firewall."
"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 initial setup could be simplified."
"The product’s price could be reduced. Also, some of its features need to be more advanced."
"We experienced a brief period of instability."
"Overall, the Kemp LoadMaster has been an all-rounder great product and stable. The free trial and virtual edition make it a breeze for any potential customer to give it a spin before actually deciding to put it on the infrastructure or even talk to the CFO."
"In the next release, Kemp should include the ability for LoadMaster to create different DNS record types."
"I definitely think that the WAF can be improved."
"SNMP and/or RESTCONF management, in order to collect many counters, for plotting in a central application need to be improved."
"They were still in the process of development, and for example, we set it up in a cluster. So it was one logistical unit built out of two physical devices. And the expected behavior, which I know from other devices, will be formed into a logic cluster. It's that you configure one unit. Then you bring the second unit into this cluster with the already configured primary unit. So the secondary box pulls all the configured ones from its neighbor, does everything automatically, and then synchronizes with this primary neighbor. And then it works, like, one logical unit. And this didn't work with the Kemp's initially, where they caused a lot of issues when building up a cluster, so there were some specials on how to set this up. When we built or set them up for the first time and the months afterward with no new software releases, there were a couple of problems, but in the end, they worked fine. So, they developed a lot and learned from what they've responded to, what we responded to them, and what needs fixing."
"Some documentation is out of date versus the new version, and things have been moved​."
"Although Kemp is very user-friendly, it lacks a more custom configuration."
 

Pricing and Cost Advice

"The solution is less expensive than F5 or Imperva and is the most reasonably priced option available."
"The price is competitive"
"The solution could be more cost-effective."
"The product has affordable pricing."
"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 average pricing. I rate its pricing a five out of ten."
"Compared to F5, FortiADC pricing is better."
"Setup is easy, the cost is affordable, and the licensing is quick and simple."
"The price is great and the value is definitely there."
"The price is lower than other options."
"Licensing is yearly and I am going to guess that it is CAN $2000.00."
"The setup cost and pricing plan is reasonable and will ultimately give you a worthy return."
"KEMP gives away free trials for 30 days. This can be stretched if you want. During the test, you will have access to KEMP support.​"
"Currently, no cost is involved with a virtual load balancer. They have used open source. We did not pay for software. We paid for the expertise. We are only paying the consulting charges, which are very reasonable, that is, around a thousand dollars."
"This is a cost-efficient product."
