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

"Because ADC is the intermediary between the servers and the end-user application, it gives thorough information about the traffic, what the problem is."
"TSL and SSL offloading are both very good features."
"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."
"The most valuable feature is the SSL offloading capacity."
"I like the solution's load balance with DNS intelligence."
"Key features include SSL Offloading, VM availability, and L7 load balancing."
"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."
"I am impressed with the product's load-balancing feature."
"We are most impressed with the ease of use and great support."
"Great web balancing and remote access balancing."
"The user interface is very easy to work with."
"Mitigates content security policy issues."
"The most valuable feature so far has been the high-availability options that allowed us to add an additional Kemp LoadMaster VLM virtual appliance into our VMware vSphere environment, to provide failover for our existing LoadMaster."
"Managing and maintaining multiple servers is done in a single place."
"LoadMaster is easy to deploy and understand."
"The configuration is really easy and the web portal is self-explanatory."
 

Cons

"I think it would be helpful if Fortinet put more video examples on their cookbook site."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"The initial setup could be simplified."
"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."
"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 user interface could be more friendly and CLI could be more like that of Fortigate."
"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 configuration is relatively complex."
"So far, the only hitch we have run into is that would have been nice to have an easier method to add allow/whitelist entries into the Access Control lists for virtual services."
"We have experienced at least one problem with stability, although it was fixed with an upgrade."
"I want to have the ability to pull a particular server. The DevOps portion was challenging for me, like if I needed to redirect from one IP to another URL. I needed to look that up, and the knowledge base is not well organized. When I look for information about Kemp on the Internet, I don't find many articles or something like that."
"If I had to change something it would maybe be to have a little better reporting graphics that show more details in the reporting. It seems to be a little small in the graphic, and I'm not sure if possible but maybe a GUI page that one can use to monitor if any server goes down."
"Certificate installations could be simplified and modernized, and allowed to be monitored for expirations/issues."
"If there is anything that needs to be updated, the GUI can get a refresh to make it look more like 2020, although it is just a cosmetic change."
"Perhaps Kemp could offer some training videos."
"If you want logging for SMTP traffic, you have to enable ESP, which requires you to define allowed IP addresses. That’s irritating, to say the least."
 

Pricing and Cost Advice

"I believe the price is good. It's fair. There are no extra costs."
"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."
"The solution could be more cost-effective."
"Compared to F5, FortiADC pricing is better."
"The price is competitive"
"The product has average pricing. I rate its pricing a five out of ten."
"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."
"The product has affordable pricing."
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"At $2,500 USD, this is absolutely a fantastic buy for the money!"
"Any decent product will cost money and if you want great support and a great product, then you will want to spend the money on it."
"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."
"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.​"
"The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money."
"​I have control on the licensing and all the prices since I work for a partner.​"
"It has a great price for the solution they offer."
