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.
Roger Seelaender - PeerSpot reviewer
Great WAF - low-maintenance solution that performs as advertised
The solution can be improved with the development of a SIP engine because it is difficult to manage SBCs. All SBCs are really tough to write rules for. If we could put this in front of an SBC to have the right rules to possibly block the traffic, that would be very helpful. The solution can also improve the relationship between Loadbalancer.org and Metaswitch, or now, Microsoft because Metaswitch was purchased by Microsoft. They both position themselves as certified but don't always talk to each other. I wish there would be closer integration between the solution and the vendors when either release new upgrades to their product line. Often we find issues on either end post upgrades.
DEMİRHAN ÇAVUŞOĞLU - PeerSpot reviewer
A tool for centralized management including inventory and sales tracking
Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Quotes from Members

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

Pros

"Key features include SSL Offloading, VM availability, and L7 load balancing."
"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."
"Content caching and content compression are good features."
"I like the solution's load balance with DNS intelligence."
"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."
"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 user interface is very easy and integrates with Sandbox easily."
"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."
"For now, it's stable."
"We now get notifications when pool members go down, and we eliminate our downtime by not sending traffic to downed pool members.​"
"The connection that this solution helps our servers maintain has been most useful."
"It's pretty much a Swiss Army knife for managing all the load balancing techniques."
"Most important for us that it makes sure that the load is distributed and that we always have access to the end servers."
"Loadbalancer is easy to use. It performs well, with low latency."
"The user interface precludes need to be well versed with Linux IPVS command line. This make it easy for junior team members to participate in managing load balancing needs."
"The load balancers have an easy installation and a relatively simple, easy user interface to use."
"The solution can scale."
"The most impressive thing about Citrix ADM is that we don't encounter latency."
"An essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently."
"The load balancing and VPN features are most valuable. AAA authentication is also valuable."
"The most valuable feature of Citrix ADC is its ease of use."
"I like the ease of use. It's easy to manage. I also like it's ease of use with virtualization technologies with applications."
"It is a stable solution. It crashed only once, four years ago...There is a return on investment using the solution."
"The most valuable features are for the ADMs and the overall monitoring environment."
 

Cons

"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."
"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."
"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."
"FortiADC is complex to configure so the interface should be improved."
"Setup could be easier. The company's homework is to redesign those menus to configure with the smallest number of steps."
"It would be good if they built in a fully functional web application firewall."
"I think it would be helpful if Fortinet put more video examples on their cookbook site."
"​I would like a notification when a new version of the software is available. They told me to sign up for their newsletter, but I have not received any notification for a newer software version.​"
"The configuration is somewhat complicated. Someone who does not know the solution may find this challenging."
"The solution can be a bit pricey."
"An area for improvement in Loadbalancer.org is that sometimes it works fine, but sometimes, it has issues. The setup for Loadbalancer.org is also complex, so that's another area for improvement."
"It would be great if there was a way to gain access to the graphing data, to create custom reports. If we had a way to use the graphing data, we could use it to present certain information to our client, such as the uptime status for their service."
"We could enhance the security aspects of the load balancer."
"The configuration is somewhat complicated. Someone who does not know the solution may find this challenging."
"If I have to say something, I suppose they could add an automated configuration backup to an FTP location (or something similar) so you don’t have to manually do it. I don’t see this as a problem, of course, as the configuration rarely changes and we only need one backup, but maybe for other users that feature would be handy."
"We would like to see some fairly large scale improvement in the configuration process for this solution."
"Their upgrades are not very backward compatible, and sometimes they mess up."
"I feel that Citrix NetScaler's customer support needs to improve."
"I would like to see them make it easier to do some of the more complex things. For example, a web re-direct requires two pieces to it. You have two ports and when people want to go to a web page, they just type in the webpage that on the backend it will redirect them to a secure link. The initial setup of that is cumbersome because you have to do it twice. There are things that can be replicated. The IP address, for example, is the same. This change would go a long way. Don't make me do it twice and don't make me have to read tons of documentation to figure out how to do it. Ease of configuration for some of the more complex processes would be a good improvement."
"Its GUI should be improved. Its CLI is powerful, but GUI needs more features."
"The licensing model and technical support of the solution could be improved."
"The solution can improve their support and send tickets directly to a Citrix ADC engineer in order to avoid having to escalate each support call."
"Integration with other third party providers and third party applications could be better because it can be a bit complex at present."
 

Pricing and Cost Advice

"The solution's pricing is an issue and should be improved."
"They offer a perpetual license."
"Compared to F5, FortiADC pricing is better."
"The solution is less expensive than F5 or Imperva and is the most reasonably priced option available."
"Our basic license excludes features such as antivirus and IDS. Due to license limitations, some functionalities are not configured."
"The product has average pricing. I rate its pricing a five out of ten."
"The solution could be more cost-effective."
"The price is competitive"
"It was easy to upgrade the license for unlimited clusters and servers. Pricing is fair."
"For now, it's stable."
"These guys make their pricing scheme really easy.​"
"Loadbalancer.org is based on open-source products, but it requires money for support and other activities."
"It is inexpensive, and even their “unlimited” version, the VA MAX is still far cheaper than competitors."
"The costs associated with Loadbalancer.org depends on the technology. For some, we need to pay, but others are open, so they're free."
"I’m not entirely sure about the rating since I'm not very technical. I haven't thoroughly compared the ratings. So, if you're asking for my impression so far, I would rate it around five out of 10."
"Licensing fees are paid annually."
"The license for Citrix NetScaler is on an annual basis and it is reasonably priced."
"Citrix ADM costs us approximately $5000 per month."
"Our licensing fees including technical support are approximately $3,500 USD."
"Ninety day free trial makes it easy to try out this solution."
"The pricing for Citrix Web App and API Protection is unreasonable. I don't know the exact price, but I heard it's tens of thousands and it's a bit too much for the small country I live in."
"I rate the pricing an eight out of ten since it is expensive."
"It is true that it is a bit pricey compared to newer technologies coming to the market. For example, A10 is a load balancer that does everything that Citrix can and it does a lot more than what NetScaler does when it comes to the security space, and their prices are so cheap. Every box comes with its own license and support built into it. When you compare that with NetScaler, you have to buy licenses separately, you have to buy a support agreement that is going to be separate. A small NetScaler, even if it is a VPX which is a virtual server, could cost you close to $150,000 to $200,000 dollars. So the pricing is really high."
"The client pays for the Citrix NetScaler license annually."
