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

Head of Cybersecurity at Technovage Solution
A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market
I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"Failover is seamless and our services are rock solid."
"The most beneficial function of using the ADC is to ensure this resiliency."
"The DNS Load Balancer makes it so that I don't have to worry about site failures."
"The most valuable features for us are the Load Balancing and Web Application Firewall, as we have a lot of web applications."
"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."
"Using Kemp as a front-facing service appliance, it allows me to have the flexibility of swapping out real servers behind the scenes without any intervention from my network team."
"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."
"We had some issues in patching management, so we deployed this product for virtual patching, the IPS rule, and it gives us very good results because we have very critical servers."
"The support team was helpful."
"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."
"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."
 

Cons

"The only thing I have struggled with is setting up automatic backups."
"They need to improve the UI environment. Currently, it's hard to navigate and use product."
"Over the last several major versions, the GUI has remained virtually unchanged and still seems lacking."
"It would be very helpful to get all the http/https session logs by default in the log monitor without activating debugging mode like an apache web sever natively does"
"To make it a perfect ten out of ten it would need better connection logging. If there is an active connection, that there is better logging. It should also have better management monitoring tools."
"I think there should be more visual instructions on how to configure advanced features."
"The cost of the GEO upgrade is not cost-prohibitive but it's something that would be a nice add-in, out of the box."
"The only thing that I miss is that the TMG server was giving me live information about who is connected and what is the request about."
"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."
"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
 

Pricing and Cost Advice

"The Kemp LoadMaster is a tremendous value."
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"This product has good value and features for the money."
"It has a great price for the solution they offer."
"The product definitely provides what the organization needs and its cost is reasonable considering the value it brings."
"Any decent product will cost money and if you want great support and a great product, then you will want to spend the money on it."
"Less expensive than Citrix."
"The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money."
"On a scale of one to ten, where one represents a cheap option, and ten represents an expensive option, I would rate the solution a seven in terms of cost."
