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

"The protection resources and the support are valuable features of the solution."
"The product's initial setup phase was really easy."
"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."
"Compared to other DDoS mitigation solutions with similar deployment, FortiDDoS does not require a 24x7 NOC and has lower TCO."
"It is a user-friendly product in terms of monitoring and updating policies."
"I find the interface easy to use."
"I find this product the best on-premises (in-line) DDoS mitigation solution that suits my current and future requirements."
"The solution is very user-friendly and very easy to use."
"Mitigates content security policy issues."
"There is a simplicity to the setup and configuration."
"The user interface is very easy to work with."
"Great web balancing and remote access balancing."
"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."
"The DNS Load Balancer makes it so that I don't have to worry about site failures."
"Exchange load balancing and reverse proxy for Skype for Business are key features."
"We are in touch with their team, and they are very collaborative."
 

Cons

"Earlier versions of firmware had bugs that limit my options."
"All those thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"Technical support isn't too good with Fortinet. They could be more responsive and helpful overall."
"The solution can be a little more user-friendly and it can be more affordable."
"Alerts and reporting features must be improved."
"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
"It would be much easier to have the management interface directly integrate with the Kemp Support library, allowing you to choose the desired template from the online catalog to then directly download to the LoadMaster."
"I think there should be more visual instructions on how to configure advanced features."
"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."
"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."
"The product is really good as-is out of the box. If there is one thing I would change is to have the license file not be coupled with the MAC address of the device. This is actually not really useful in a virtual environment where if you have a single VM with KEMP LoadMaster and you have not set up static MAC Address, if you, for example, recreate the VM and just load the disk file on a new VM it will get new MAC address and the NLB will not work as it will not see a proper license."
"The UI is very basic and not very attractive, so this could be an area for improvement."
"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."
"Hardware version needs a dual power solution."
 

Pricing and Cost Advice

"The product’s pricing needs improvement."
"The solution is reasonably priced."
"It's quite pricey."
"From a cost perspective, Kemp is very competitive and is not hard to justify by any means."
"This is a cost-efficient product."
"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."
"They have multiple tiers of licensing and you can upgrade it easily."
"The pricing is alright and we pay a monthly licensing fee"
"The license varies according to the number of megabits."
"This product has good value and features for the money."
"Less expensive than Citrix."
