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.

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

"It helps with defining server load balancing tasks and managing SSL certificates, ensuring the communication flow through the Fortinet gateway."

"Ease of use in deploying and having it up and running requires minimal knowledge."

"I am impressed with the product's load-balancing feature."

"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."

"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."

"We can do patches offline without causing customers outages. The web application firewall features, especially those related to the OWASP Top Ten, provide automated protections. This allows more flexibility in patching the backend applications. Additionally, it offers visibility into the requests being made to the applications, and you can't protect what you can't see."

"The most valuable feature is the SSL offloading capacity."

More Fortinet FortiADC pros

"The load balancing feature of this solution is very good."

"It has helped us to increase the resiliency of the application and the performance."

"It is a complete solution for those looking for an all-in-one."

"Scalability is great. One of the best features of NetScaler is that it can scale out."

"The most valuable features are for the ADMs and the overall monitoring environment."

"Content filtering, security layer, and application customization features are the most valuable."

"The flexibility in configuration options is impressive."

"The load balancing and VPN features are most valuable. AAA authentication is also valuable."

More NetScaler pros

Cons

"Issues with SSL and encrypted traffic."

"FortiADC is complex to configure so the interface should be improved."

"I will queue all the details clearly on the ticket, including the diagram, log files, and everything else. Once a case is assigned, they ask the same questions again without checking the submitted details."

"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."

"Fortinet FortiADC should include an advanced-level SD-WAN."

"The product's stability for VMs could be better."

More Fortinet FortiADC cons

"Reducing the overhead required for AppFlow data collection, specifically for HDX Insight, would be a huge improvement."

"Getting to use some of the advanced tools, even with the assistance of Citrix support, can be challenging."

"Citrix ADC can be really complex. It isn't very simple like some other appliances that I've worked with. You need a lot of skill and experience to manage it. I'm not talking about a year or two. You need at least four years to understand it very well. It is not that easy to learn. They should make it a lot simpler for users to understand the management of it. They can also provide some additional training. The material they have on the site is not sufficient enough for you to understand how to manage it. Their training is expensive, and not everyone has the funds and experience for it. Citrix isn't very popular around these parts of the world. So, it can use some more marketing, sales, enlightenment, and advertisement. These could bring more market for them. Basically, there are just a few companies that really go for Citrix. Most of the companies go for VMware because they marketed themselves more than Citrix. There isn't much difference between Citrix and VMware. VMware is a little more robust than Citrix. Citrix has focused more on desktops rather than server virtualization, and that's the advantage VMware has over Citrix. Citrix also needs to educate and inform users about the infrastructure that is supported with a version. Currently, if the customers don't look at the datasheet, they might miss this important information."

"The only thing customers told me that could be improved is that they would like to be able to purchase and receive the products in one box, rather than two boxes. This is something related to marketing, though."

"We would like the licensing model for this product to be improved, as it isn't currently very transparent. There isn't a standard package available, and each extra feature creates an additional cost."

"Citrix ADC is a complex product, and it takes time to understand these things. But the documentation is poor, and the deployment is difficult. Integration could also be better because what I find is that you cannot easily integrate the panel in the second sector. What I have found is that in the last index, there is a limitation when getting validated. Technical support could also be better."

"The configuration for its web application firewall is complicated."

"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."

Pricing and Cost Advice

"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 could be more cost-effective."

"I rate Fortinet FortiADC's pricing one out of ten. It is fixed."

"The solution's pricing is an issue and should be improved."

"The price is competitive"

"The solution is less expensive than F5 or Imperva and is the most reasonably priced option available."

"The product has average pricing. I rate its pricing a five out of ten."

More Fortinet FortiADC pricing and cost advice

"We get value for money. Its price is fair. I don't think it is overpriced."

"We are quite happy with price. It's not too high."

"When compared to other solutions, the cost is high."

"The solution is expensive compared to one of its competitors."

"I do not have any experience with the pricing of the product."

"The tool is cheap."

"Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much."

"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."
