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

"Persistence is very valuable. This holds the connection information of the source and that connection is important to RDP and our APO calls. The connection has to be persisted to the original source to operate properly. We also use the subsections for sub-services to create services inside our services for our API resources, this is most awesome. We would not be able to do this without Kemp and offer this type of sub-service to route based on an API instance. It routes the traffic properly based on the sub-service type."
"Since we started using Kemp, we have become more reliable and have less downtime."
"It's been a great reliable product for us, and I would recommend it to anyone!"
"​Simple to install with good documentation."
"Mitigates content security policy issues."
"Scalability-wise, I rate the solution a ten out of ten...I rate the technical support a ten out of ten...The initial setup of Kemp LoadMaster is very simple."
"The security features, load balancing, built-in templates, and the easy to implement virtual IPs are great."
"I can sleep at night because of the Kemp Load Balancer, just knowing that in case of a failover, the email will keep flowing and our users will have access in the morning."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
"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."
"The support team was helpful."
"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."
"Nexusguard has exponentially improved the availability of our services because we don't have to worry much about any threats or DDoS attacks towards our services."
"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."
"Nexusguard has given us confidence that we are protected against any outside attacks."
 

Cons

"Obviously, there are a lot of moving parts and fieldssettings on Kemp LoadMaster. Not all the settings are easily understandable."
"The configuration of basic services is pretty straightforward but when you want to configure more advanced settings like the Edge Security Pack feature, it can be somewhat challenging."
"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."
"So far, the only hitch we have run into is that would have been nice to have an easier method to add allow/whitelist entries into the Access Control lists for virtual services."
"There are some challenges with updates on certain models that don't have a few features."
"There is room for improvement in the stability of the solution."
"UI is very basic and unattractive."
"With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
"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."
"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."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
"One of the features that should be added to the next release is report generation."
"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."
 

Pricing and Cost Advice

"The pricing is alright and we pay a monthly licensing fee"
"From a cost perspective, Kemp is very competitive and is not hard to justify by any means."
"It has a very attractive ratio of price/performance."
"Less expensive than Citrix."
"KEMP gives away free trials for 30 days. This can be stretched if you want. During the test, you will have access to KEMP support.​"
"It has a great price for the solution they offer."
"Setup is easy, the cost is affordable, and the licensing is quick and simple."
"This product has good value and features for the 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."
