Saeid Khanipour Ghobani - PeerSpot reviewer
High-level load balancing and routing protocols but scalability is limited to 200 gigabits
The initial setup and configuration are very easy because the solution includes a simple OS. Initial configuration takes about ten minutes for simple environments. It is important to assess the environment and decide what services, servers, and web applications are needed. The solution can be configured in router mode or one-arm mode which uses source NAT as destination NAT to send traffic to the firewall. One-arm mode is more complex and requires discussions with our engineers. For example, you have a website with Node.js for your programming language, Amazon S3 for your CDN, NGINX for your web server, and you use both React and reCAPTCHA. Our team meets with your developer to learn your website and OS through a multi-step process and then we configure the solution to protect everything.

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 solution provides high-level services such as availability, redundancy, and load balancing between servers."
"From a technical perspective, it is the most scalable device from Fortinet."
"The most valuable feature is its simplicity."
"I use load balancing technology like Round Robin or low weight to maintain session-based connections. This ensures that clients can connect to their applications without interruption."
"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."
"It helps with defining server load balancing tasks and managing SSL certificates, ensuring the communication flow through the Fortinet gateway."
"FortiADC provides load-balancing capabilities needed for integration with other Fortinet platforms."
"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."
"Great web balancing and remote access balancing."
"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)."
"The feature I find most valuable is load balancing with different algorithms."
"The pricing of the solution is valuable."
"We really like the performance of this solution."
"It is an easy-to-use, user-friendly interface, and you can set up a new VIP in a couple of minutes."
"Load-balancing is a great feature that is very easy to configure and it is always working fine."
"There is a simplicity to the setup and configuration."
 

Cons

"I think it would be helpful if Fortinet put more video examples on their cookbook site."
"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."
"The solution’s pricing could be improved."
"The solution should improve finding false positives and false negatives. There are a lot of false positives."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"The solution's WAF needs an upgrade because it is not as good as FortiWeb, VMware, F5, or Imperva."
"When the FortiADC is part of a platform with components like FortiManager and FortiGate, automation and pushing configuration are very inconvenient."
"FortiADC is complex to configure so the interface should be improved."
"We have experienced at least one problem with stability, although it was fixed with an upgrade."
"Several elements of the GUI need work. For example, if you have many content switches, it’s difficult to find the ones you need. And where is the search feature?"
"The ability to see live traffic is not great and can be improved."
"The cost of the GEO upgrade is not cost-prohibitive but it's something that would be a nice add-in, out of the box."
"I definitely think that the WAF can be improved."
"Over the last several major versions, the GUI has remained virtually unchanged and still seems lacking."
"The product could be improved by making the SSL Offloading easier."
"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"
 

Pricing and Cost Advice

"The solution could be more cost-effective."
"The product has average pricing. I rate its pricing a five out of ten."
"The product has affordable pricing."
"The price is competitive"
"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."
"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 solution's pricing is an issue and should be improved."
"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."
"They have multiple tiers of licensing and you can upgrade it easily."
"​I have control on the licensing and all the prices since I work for a partner.​"
"The price is great and the value is definitely there."
"This is a cost-efficient product."
"The product definitely provides what the organization needs and its cost is reasonable considering the value it brings."
"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."
"The license varies according to the number of megabits."
