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.

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.

Quotes from Members

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

Pros

"From my personal experience, many firewalls provide Load Balancing functionalities, but Kemp Loadmaster has a lot of features and functionalities like what you can configure. So there are a lot of features but we use only five percent of it."

"It has been functional. We don't have any outages."

"The DNS Load Balancer makes it so that I don't have to worry about site failures."

"We are most impressed with the ease of use and great support."

"Mitigates content security policy issues."

"The pricing of the solution is valuable."

"The most valuable feature so far has been the high-availability options that allowed us to add an additional Kemp LoadMaster VLM virtual appliance into our VMware vSphere environment, to provide failover for our existing LoadMaster."

"The most beneficial function of using the ADC is to ensure this resiliency."

More Kemp LoadMaster pros

"We have about 30,000 connections going through at any one time and it's fine, it doesn't seem to sweat. It doesn't get overloaded."

"I found scalability in Loadbalancer.org valuable."

"It does what it’s supposed to do which is balancing an important intranet site we are using, so if one server dies, the second becomes active straight away."

"The performance is good."

"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 most valuable features of Loadbalancer.org are related to its load balancing capabilities."

"The SSL Layer 7 load balancing is valuable."

"The connection that this solution helps our servers maintain has been most useful."

More LoadBalancer Enterprise pros

"I like app flows and custom flows. They integrate with multiple flows."

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

"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."

"The solution's technical support is good."

"We use the product for load balancing and as a reverse proxy solution."

"When our primary link goes down I can still get to my Cisco devices and the NetScaler devices on-prem because of the SDN solution. If the internet connection at one of the branches goes down, we can still route them, they still get internet based on the SDN solution through one of the other sites. They can carry on working."

"Its flexibility, agility, and robustness are the most valuable. Its management and implementation are also quite easy."

"My customers have told me that the performance of this solution is good."

More NetScaler pros

Cons

"I would like to see more automation and control of overactive and inactive resources. If I could schedule these around our updates then it would be all automated. I would like to set up an automated script to coincide with the scripts I use to update resources and servers."

"Some documentation is out of date versus the new version, and things have been moved."

"They need to improve the UI environment. Currently, it's hard to navigate and use product."

"We experienced a brief period of instability."

"When we go serverless, we may again have to revisit this because the configuration needs to be changed. With this change, we can run into a lot of other configurations that we haven't got into, which involve additional expenses. It would be challenging to convince management to buy at that price point. It would be a balancing act of justifying that expense and the value, that is, how it is going to save a bit of time and make our platform secure. It can have better configuration ability. A lot of iterations happen when we have multiple servers pointing to the same domain. If we do not orchestrate carefully, it gets into a loop, which takes away the precious time of the user who is trying to subscribe to a service. It takes a little longer time to realize services as well as web pages."

"There is room for improvement in the stability of the solution."

"In my opinion, the layer seven loads balancing that we're mainly using for web servers, doesn't seem to pick up when there are issues at the application level."

"In the next release, Kemp should include the ability for LoadMaster to create different DNS record types."

More Kemp LoadMaster cons

"I would like it if Loadbalancer had the ability to make rules for specific shared bots."

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

"Possibly a more graphical overview page (with colors) to give a two second overview to see if everything is working fine."

"Originally we had some stability issues with it, so they replaced it with a new box and it's fine."

"There is room for improvement in Loadbalancer.org in certain areas."

"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."

"We could enhance the security aspects of the load balancer."

"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."

More LoadBalancer Enterprise cons

"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."

"In terms of what could be improved, I would say the user interface because sometimes it can be complicated."

"Citrix should offer a demo or free-trial version of NetScaler. Several other vendors do, but Citrix does not. Pricing should also be more readily available."

"The solution's pricing is a big concern and should be improved."

"The configuration is complex, and only one or two people know how to assist when problems arise."

"Citrix Web App and API Protection could improve in the area of licensing"

"The product could be improved by making it easier to use and easier to implement."

"The setup for Citrix NetScaler has room for improvement. It could be easier."

More NetScaler cons

Pricing and Cost Advice

"They have multiple tiers of licensing and you can upgrade it easily."

"The price is lower than other options."

"The license varies according to the number of megabits."

"Setup is easy, the cost is affordable, and the licensing is quick and simple."

"From a cost perspective, Kemp is very competitive and is not hard to justify by any means."

"At $2,500 USD, this is absolutely a fantastic buy for the money!"

"It has a great price for the solution they offer."

"This is a cost-efficient product."

More Kemp LoadMaster pricing and cost advice

"It filled a requirement for our project, and it did so at lesser cost than their competitors."

"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."

"It is inexpensive, and even their “unlimited” version, the VA MAX is still far cheaper than competitors."

"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."

"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."

"It was easy to upgrade the license for unlimited clusters and servers. Pricing is fair."

"We've got an unlimited license, which doesn't costs that much compared to other vendors, and we don't have to buy it again."

More LoadBalancer Enterprise pricing and cost advice

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

"It is an enterprise solution. Thus, its costs are reasonable."

"The tool is cheap."

"The licenses for this product are payable as a yearly subscription, and carry a high price-point. The subscription scheme is quite complicated, and costs will increase with each additional feature that is required, outside of the basic setup."

"Ninety day free trial makes it easy to try out this solution."

"Our licensing fees including technical support are approximately $3,500 USD."

"The solution is undoubtedly very good, but it is expensive."

Overview

Kemp LoadMaster is a powerful load balancing solution that also serves as a web application firewall. Its primary use case is load balancing and application load balancing, making it an ideal solution for organizations that must distribute traffic across multiple servers. Kemp's integration with an active directory for ESP usage, hosting/deployment of SSL certificates, and pricing are some of its most valuable features.

Using Kemp has helped organizations mitigate cross-scripting vulnerabilities, cookie-related issues, and content security policy issues. It has also allowed them to handle everything with Kemp instead of working on each application individually.
