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.

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.

The integrated application protection has helped secure our critical web applications

Valuable features of Radware Alteon include global server load balancing, SSL offloading, Layer 7 load balancing, automation and traffic scaling, real-time analytics, and reporting. Alteon's integrated application protection has helped us. As a state government agency, we face increasing threats and need to secure our critical web applications. Our finance websites are the primary targets for DDoS, SQL injections, and other sophisticated attacks. Traditional security is insufficient to defend against the volume and complexity of the attacks. We need protection against attacks on the application and infrastructure layers and DDoS attacks. Alteon offers visibility and actionable insights into each security event. Radware has free training available on their website. I've completed a few training courses and found them very helpful for me in my daily work. The basic course covering the UI takes a week, and it was easy to understand. When we're troubleshooting a scenario, we can check the Alteon knowledge base articles. The combination of training and the knowledge base shortens the learning curve.

Quotes from Members

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

Pros

"The SSL Layer 7 load balancing is valuable."

"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 features I find valuable in this solution are the ease of managing the logs on the WAFs, the ease to identify break-in attempts into the network, the front-end firewall, and a more specific firewall."

"It helps us to route the traffic to the available servers. If we didn't have Loadbalancer we would fail to set the end-user and it would cause a failure in the cluster."

"The load balancers have an easy installation and a relatively simple, easy user interface to use."

"The performance is good."

"I found scalability in Loadbalancer.org valuable."

More Loadbalancer.org pros

"We appreciate that this solution facilitates our access to Citrix internet."

"Available on any device and can be accessed on a wide area network."

"I would say the rewriting and redirection functions are must-have's for us."

"We like the periodic upgrades and backups, also made via ADMs, and it makes our environment much more robust and reliable."

"It's very easy to configure."

"High availability, performance, and security are the main pillars. It enhances the security for accessing the applications."

"I like the ease of use. It's easy to manage. I also like it's ease of use with virtualization technologies with applications."

"The solution was very easy to deploy."

More NetScaler pros

"his solution allows me to secure applications, by blocking suspicious traffic based on the signature that has been enabled for that particular application."

"The most valuable feature is the support from the engineering team."

"The product offers high availability."

"Alteon helps us troubleshoot issues. It provides us statistics on application, server, and load balancer response that we can use to identify problems or latency."

"The UI is user-friendly."

"The integrated application protection provided by Alteon is very good. It really helps to avoid false positives in some cases. It provides important granularity to avoid a situation in which security or cybersecurity scenarios escape us."

"Overall, I would rate Alteon a nine out of ten."

"The most valuable feature of the solution is its stability. During the time that I have been using it, it has not undergone a service failure... And with the integrated application protection, we have not suffered from attacks anymore."

More Radware Alteon pros

Cons

"I'd like to see scalability improved; it can be costly."

"Loadbalancer.org's complexity could be reduced."

"The configuration is somewhat complicated. Someone who does not know the solution may find this challenging."

"There are many features you can set in the backend of Loadbalancer. They should simplify the configuration. The administrator should be able to configure it more simply. How it is now, you can only configure it if you have a lot of experience."

"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."

"It doesn't have the bonding capability feature."

"They're mostly designed to balance a particular type of traffic. I wanted to load balance DNS, and they just don't do it the way that we wanted to. So they're not used as DNS load balancers."

"The configuration is somewhat complicated. Someone who does not know the solution may find this challenging."

More Loadbalancer.org cons

"The interface could be improved, some customers struggle with that."

"Their upgrades are not very backward compatible, and sometimes they mess up."

"I think there is always room for improvement in this type of solutions. For example, I think the GUI should be easy to understand."

"It was challenging explaining to customers that it's no longer NetScaler but ADC, and now it's not just ADC but also the rebranding from NetScaler."

"An area for improvement in Citrix Web App and API Protection is for it to give real-time notifications and alerts. It would be practical if the solution warns you if there's an attack or if the load or traffic volume increases or decreases. An additional feature I'd like to see in Citrix Web App and API Protection is a prediction or artificial intelligence on what is happening, for example, attacks."

"If one device or switch fails, the failover to another device is not seamless which is painful."

"There are some features which are missing."

"ADC from Citrix has added functionalities from other products and the usability is very difficult for someone who is used to a simpler user interface, it's a little bit of a mess to use."

More NetScaler cons

"I would like to see an improved community presence, similar to the one for their main competitor, F5."

"We’d like the solution to include more security features in the standard license."

"I would like to see future enhancements in security, specifically in threat protection."

"Alteon's user interface and usability can be improved by providing a more modern and streamlined design and focusing on simplifying workflows in the UI."

"There is room for improvement in reducing the number of false positives I receive. We could benefit from more configuration options to avoid these false positives, which can be overwhelming for a security analyst."

"The solution could be more robust."

"Radware LinkProof’s customer support could be improved."

"Alteon's user interface could be improved. F5's user interface is more user-friendly than Radware's, but Radware's hardware performs better."

More Radware Alteon cons

Pricing and Cost Advice

"The solution requires an annual support license of $2,780 for four systems or $695 a year per unit for support not including the units."

"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 love that they do not price on some arbitrary throughput rating where you are guessing at what the load balancer is going to handle."

"Loadbalancer.org is based on open-source products, but it requires money for support and other activities."

"They're not the cheapest, not the most expensive, but I think value-wise, they're 100%."

"For now, it's stable."

"I think it’s very affordable."

"It's worth the cost. It's not cheap, but it's a good solution. If you're looking for a good solution, this is a good solution. Is it cheap? No. Is it worth the money? Yes, I think it is."

More Loadbalancer.org pricing and cost advice

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

"This product is more expensive than some of the competitors."

"The price for Citrix ADC here in Mexico was good, when you compare it with F5 and Radware."

"The client pays for the Citrix NetScaler license annually."

"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."

"Costly product and complicated licensing."

"There isn't much of a difference between the cost of Citrix and that of other similar solutions."

More NetScaler pricing and cost advice

"The pricing seems reasonable to me for what the solution provides. It is within the parameters of this type of solution."

"The solution is cost-efficient."

"It is not the priciest and it is not the cheapest. For our solution, it was right in the middle of price performance."

"It is the best in the industry. It was better than the competition, and that is what made us go ahead with them."

"I'm content with Alteon's pricing."

"Its pricing is very good. It is very competitive. Radware Alteon is the leader in the market. At a lesser price, we get a good product and also good support. Other vendors who are providing load balancers charge separately for two items. You have the hardware cost, and you have the support cost, whereas, in the case of Radware, you get both in a single package."

"Our government agency opted for Radware Alteon due to its affordability and efficiency. While I can't say precisely how much it costs the organization, the price per device. In India, we always look for affordable products, so I assume Alteon is cost-effective because the government chose it."

"Radware Alteon is less expensive than many of the other competitors."

Reviews from Real Users

“Loadbalancer.org is less complex than Citrix. In some cases, our customers do not have an engineer on staff who can support this device. These customers have a large number of Linux engineers but don't have the money. We suggested using Loadbalancer.org and other open-source tools. Many customers are of different sizes and have different budgets. Loadbalancer.org has everything that is needed.” - Artem M., System Engineer at CROC

“We use Loadbalancer for balancing loads in our main application. Loadbalancer is easy to use. It performs well, with low latency.” - Walid M., Network and Security Engineer at a logistics company

Loadbalancer.org

One platform for a consistent application delivery and security experience because nobody has time to learn multiple systems to manage ADC deployments. NetScaler is built with a single code base using a software-based architecture, so no matter which ADC form factor you choose — hardware, virtual machine, bare metal, or container — the behavior will be the same.
