Efficient application security while optimizing connections

The initial setup is simple; it is not complex. The configuration itself is simple and can be done in a couple of hours. However, the migration of the system to A10 Networks takes longer due to critical applications. Clients prefer to move them one by one, which is why it takes a significant amount of time. The configuration itself is simple, especially for this application.

Information Security Engineer at BOK

Displays flexible, user-friendly interface with minor licensing challenges

The product could be improved with a more intuitive interface for complex configurations and more advanced analytics. Additionally, enhanced security features, like a more robust Web Application Firewall, and stronger APIs for better automation would be beneficial. Overall, the main areas for improvement are in strengthening the advanced features to better meet the demands of large-scale enterprise environments. key features for the next release should focus on three areas. First, an enhanced, next-generation security suite with a more powerful Web Application Firewall (WAF) and integrated bot protection. Second, more advanced and customizable analytics dashboards to provide deeper insights into application performance. Finally, greater support for modern, cloud-native environments, including better APIs for automation and seamless hybrid-cloud traffic management

Quotes from Members

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

Pros

"Our clients appreciate that this is a security enabled solution."

"What I like about Lightning ADC, is that instead of having a big appliance sitting in front of the Kubernetes cluster, Lightning can pretty much go inside of Kubernetes."

"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."

"The most valuable features are synchronizing email with mobile devices and synchronizing with Outlook."

"The old process of manually having to redirect Outlook Web Access traffic and Email traffic to a second server is a thing of the past."

"I like the way this solution handles multiple SSLs in different domains while still load balancing."

"The user interface is very easy to work with."

"When you configure the listening services, you can implement a lot of security features like the Edge Security Pack that intercepts the requests and processes those before they are sent to the real servers."

"Mitigates content security policy issues."

"Exchange load balancing and reverse proxy for Skype for Business are key features."

"We needed a Microsoft Threat Management Gateway server replacement solution for a customer and were impressed with the simplified deployment of the Kemp LoadMasters."

More Kemp LoadMaster pros

Cons

"The support from A10 should be improved."

"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."

"A10 documentation is not as open and accessible as AWS and Azure documentation is."

"The GUI is rather technical and complex, so it could be improved by making it simpler and more user-friendly."

"Certificate installations could be simplified and modernized, and allowed to be monitored for expirations/issues."

"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."

"They were still in the process of development, and for example, we set it up in a cluster. So it was one logistical unit built out of two physical devices. And the expected behavior, which I know from other devices, will be formed into a logic cluster. It's that you configure one unit. Then you bring the second unit into this cluster with the already configured primary unit. So the secondary box pulls all the configured ones from its neighbor, does everything automatically, and then synchronizes with this primary neighbor. And then it works, like, one logical unit. And this didn't work with the Kemp's initially, where they caused a lot of issues when building up a cluster, so there were some specials on how to set this up. When we built or set them up for the first time and the months afterward with no new software releases, there were a couple of problems, but in the end, they worked fine. So, they developed a lot and learned from what they've responded to, what we responded to them, and what needs fixing."

"Over the last several major versions, the GUI has remained virtually unchanged and still seems lacking."

"With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic."

"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."

"If I had to change something it would maybe be to have a little better reporting graphics that show more details in the reporting. It seems to be a little small in the graphic, and I'm not sure if possible but maybe a GUI page that one can use to monitor if any server goes down."

Pricing and Cost Advice

Information not available

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

"The setup cost and pricing plan is reasonable and will ultimately give you a worthy return."

"It has a very attractive ratio of price/performance."

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

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

"It is well-priced and licensing is very flexible."

"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."

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

Overview

A cloud-native, software-defined solution that provides integrated advanced load-balancing, performance optimization, application security and per-application analytics to increase operational agility and application performance.

A10 Networks

Kemp LoadMaster is a powerful load balancing solution that also serves as a web application firewall.
