Reliable protection and smooth setup enhance company security
Currently, I have two firewalls, with one located in Sorocaba, model 90D, and the other in São Paulo, model 30D. They are connected by VPN. I use the firewalls for VPN and final protection for my company, and my equipment is maintained by an internet company called Multiprox The equipment works…

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

"Packet inspection has been effective for mitigating DDoS attacks."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"It is a user-friendly product in terms of monitoring and updating policies."
"The solution is very user-friendly and very easy to use."
"The protection resources and the support are valuable features of the solution."
"The equipment works very well, and I have not encountered any issues with it."
"The product allows the users to adjust the thresholds."
"The product's initial setup phase was really easy."
"The base feature of Kemp LoadMaster load balancing ticks all the boxes but the most valuable features would be the security features Intrusion Prevention (IPS) and Web Application Firewall (WAF)."
"LoadMaster is easy to deploy and understand."
"Failover is seamless and our services are rock solid."
"Edge Security Pack is valuable because of the way it separates between critical infrastructure and the public internet."
"It has greatly fortified the performance and uptime of our front-door email ingress, simplified and segmented mail routing, and reduced admin overhead for mail issue resolution and troubleshooting."
"The DNS Load Balancer makes it so that I don't have to worry about site failures."
"I like that this is a Network Load Balancer that can be used practically with any application in the backend. They have how-to guides on how to set up Kemp NLB with Exchange, but you can use it as well for Sharepoint, RDS, or any other back end server."
"One of the most valuable features I like is the ability to block specific cipher suites like RC4, and older protocols like SSL 3.0."
 

Cons

"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."
"The solution can be a little more user-friendly and it can be more affordable."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"The web interface could be much better."
"The product’s pricing needs improvement."
"In the web interface, there are a lot of settings in the different menus and it would be helpful if there were an interactive help system or tooltips to help the administrators find and configure the right settings."
"Certificate installations could be simplified and modernized, and allowed to be monitored for expirations/issues."
"I think there should be more visual instructions on how to configure advanced features."
"Overall, the Kemp LoadMaster has been an all-rounder great product and stable. The free trial and virtual edition make it a breeze for any potential customer to give it a spin before actually deciding to put it on the infrastructure or even talk to the CFO."
"The auth website of ESP is really lacking. It’s not responsive (mobile friendly) and the procedure of changing the website is difficult. We tend to avoid using pre-auth for that reason."
"It would be nice if the historical metrics were easily exportable from the interface."
"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."
"I really don't like the way the logs are presented in the software."
 

Pricing and Cost Advice

"The solution is reasonably priced."
"It's quite pricey."
"The product’s pricing needs improvement."
"This is a cost-efficient product."
"Licensing is yearly and I am going to guess that it is CAN $2000.00."
"The price of the solution is cheap."
"Setup is easy, the cost is affordable, and the licensing is quick and simple."
"Download Kemp's VLM trial and take it for a test drive; you will be impressed."
"It has a great price for the solution they offer."
"The license varies according to the number of megabits."
"Less expensive than Citrix."
