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

"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."
"This ensures that clients can connect to their applications without interruption."
"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."
"FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms."
"Fortinet FortiADC is a good product because each and every piece of content is monitored by it."
"The solution provides high-level services such as availability, redundancy, and load balancing between servers."
"The most valuable feature is its simplicity."
"Customer service is excellent."
"Great web balancing and remote access balancing."
"The solution is easy to configure when changing the load balancing method to Round Robin or least connection."
"It has greatly fortified the performance and uptime of our front-door email ingress, simplified and segmented mail routing, and reduced admin overhead for mail issue resolution and troubleshooting."
"Exchange load balancing and reverse proxy for Skype for Business are key features."
"We needed a Microsoft Threat Management Gateway server replacement solution for a customer and were impressed with the simplified deployment of the Kemp LoadMasters."
"The Global WAF has saved us more than one time from unwanted traffic."
"We are most impressed with the ease of use and great support."
"The base feature of Kemp LoadMaster load balancing ticks all the boxes but the most valuable features would be the security features Intrusion Prevention (IPS) and Web Application Firewall (WAF)."
 

Cons

"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."
"Fortinet FortiADC should include an advanced-level SD-WAN."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"Issues with SSL and encrypted traffic."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"Technical support and documentation could both 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."
"I think it would be helpful if Fortinet put more video examples on their cookbook site."
"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."
"The only thing that I miss is that the TMG server was giving me live information about who is connected and what is the request about."
"The product is really good as-is out of the box. If there is one thing I would change is to have the license file not be coupled with the MAC address of the device. This is actually not really useful in a virtual environment where if you have a single VM with KEMP LoadMaster and you have not set up static MAC Address, if you, for example, recreate the VM and just load the disk file on a new VM it will get new MAC address and the NLB will not work as it will not see a proper license."
"It would be very helpful to get all the http/https session logs by default in the log monitor without activating debugging mode like an apache web sever natively does"
"Some documentation is out of date versus the new version, and things have been moved​."
"Some of the support documentation seems to make assumptions that the person installing or configuring is experienced with the product or concepts."
"It has all types of logs and they are very detailed, but it's a little bit hard to search for a single event."
"The only thing I have struggled with is setting up automatic backups."
 

Pricing and Cost Advice

"Compared to F5, FortiADC pricing is better."
"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."
"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."
"The price is competitive"
"The solution's pricing is an issue and should be improved."
"The product has affordable pricing."
"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."
"The license varies according to the number of megabits."
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"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."
"It is well-priced and licensing is very flexible."
"The setup cost and pricing plan is reasonable and will ultimately give you a worthy return."
"They have multiple tiers of licensing and you can upgrade it easily."
"The price is great and the value is definitely there."
"The product definitely provides what the organization needs and its cost is reasonable considering the value it brings."
