Bonieber  Orofeo - PeerSpot reviewer
Identifying compromised traffic and securing data has been a significant advantage
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) ( /products/f5-big-ip-local-traffic-manager-ltm-reviews ) is its ability to identify compromised traffic and its capabilities in authentication. Additionally, the security aspect of it provides a significant advantage as it helps us secure our data, which is a major investment and benefit for us. Before using this system, we had difficulties in storing our data and managing the traffic that comes in and out.
PeterForster - PeerSpot reviewer
A highly stable and scalable load-balancing software that offers great technical support
My company is really happy with Kemp LoadMaster as a product. My company is also happy with the support we receive from Kemp LoadMaster. 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. Feature-wise, Kemp LoadMaster has everything that our company's customers require. Kemp LoadMaster also has features that have supported our company's past projects.

Quotes from Members

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

Pros

"We use F5 BIG-IP Local Traffic Manager to balance traffic."
"The scalability of the solution depends on the sizing of the network. Generally, the scalability is quite good."
"We have found the consistency of the application always being the way it is supposed to be as its most valuable feature."
"We enjoy its overall ease of use."
"The occasion in which we needed technical support, we didn't have problems with them, because they always answered our questions without any trouble."
"It can determine if the system is going down, then route the traffic somewhere else."
"It is a very good, flexible solution. It helps us to catch up on flaws in our partner solutions on top of its load balancing feature."
"The most valuable features are DNS, APM, and ASM. Additionally, it is easy to use and you have a lot of flexibility to use the solution within a network."
"The most valuable features for us are the Load Balancing and Web Application Firewall, as we have a lot of web applications."
"​Simple to install with good documentation."
"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."
"LoadMaster is easy to deploy and understand."
"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."
"Failover is seamless and our services are rock solid."
"Security is considered the most effective feature in Kemp 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."
 

Cons

"The UI could be improved."
"Initial setup is tricky, if you do not understand the design of this product."
"While the licensing is good through the AWS Marketplace, it is more expensive than what you could buy yourself."
"For integration with other AWS environments, we do some tie-ins with some autoscaling groups. This has been challenging for us. We have had issues, where when autoscaling groups scale up, there are some instances which are not showing up in the proper size. Then, those IPs would get registered with F5, but never get released. Therefore, we are ending up with a whole bunch of ghosted IPs."
"Based on my experience using F5 and by only taking into consideration the last seven years, I have found that the reporting mechanism is bad."
"Security and Reporting."
"We need best-practice information. They have something called DevCentral and a blog. But we want something from F5 itself regarding how to tackle the false-positive configurations. If you go into detail with so many configurations it will find so many false positives from the moment it is enabled that it will quickly impact your applications, and it will not work."
"In terms of native integrations, there is a lot of instability. Also, integration is not robust with F5."
"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."
"The ability to see live traffic is not great and can be improved."
"Perhaps Kemp could offer some training videos."
"There is room for improvement in the stability of the solution."
"UI is very basic and unattractive."
"They need to improve the UI environment. Currently, it's hard to navigate and use product."
"The configuration of the basic services is pretty straight forward but for more complex solutions, there needs to be better documentation or knowledge base articles."
"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"
 

Pricing and Cost Advice

"The licensing strategy for F5 is good."
"The cost is high for this product, so it's not suitable for small customers, e.g. those with small environments."
"Though functionality is high, its cost can be considered slightly higher than its competitors​."
"BIG-IP LTM is considered a premium product, so it's quite expensive and isn't affordable for all customers."
"F5 BIG-IP is a stable solution. It is quite mature and does not have many concerns."
"The solution is more expensive than one of its competitors."
"It's not a cheap product, but there are no other replacements for what we do with it."
"It was probably a one-time purchase and then you have maintenance, but I don't have the details on that. We bought what they called the Best bundle at the time, which pretty much included all of the modules. There was probably no additional cost afterward."
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"It is well-priced and licensing is very flexible."
"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."
"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.​"
"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."
"Less expensive than Citrix."
"It has a very attractive ratio of price/performance."
"The pricing is alright and we pay a monthly licensing fee"
