Featured Reviews

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) 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

"iRule feature is useful."
"The most valuable feature is being able to manipulate the iRules, so you can send traffic to different avenues."
"The most valuable feature is customization."
"The configuration and integration into the AWS environment was pretty easy."
"The setup is pretty easy."
"F5 has many capabilities for load balancing and web application firewall features."
"The solution is robust and reliable."
"It improves the overall performance of applications by decreasing the burden on servers associated with managing and maintaining applications and network sessions, as well as by performing application-specific tasks."
"We needed a Microsoft Threat Management Gateway server replacement solution for a customer and were impressed with the simplified deployment of the Kemp LoadMasters."
"​Simple to install with good documentation."
"The most valuable features are synchronizing email with mobile devices and synchronizing with Outlook."
"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."
"The pricing of the solution is valuable."
"The feature I find most valuable is load balancing with different algorithms."
"Mitigates content security policy issues."
 

Cons

"Technical support is somewhat slow and could be improved."
"A more intuitive interface would be helpful."
"The initial setup can be complex - it's quite flexible in terms of configuration, but the person configuring it needs to understand the application side, the network side, and the server."
"Fixing bugs."
"If we decide to migrate to the cloud, I don't think that BIG-IP is a good solution and we probably won't use it."
"We would like to have integration into encryption and PKI integration with SafeNet. That is probably the key component in using External PKIs, letting people bring their PKIs with them."
"Technical support could be faster. It's something I'd like to see them work on in the future."
"If they made it easier for engineers to get F5 training then it would be better."
"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."
"I really don't like the way the logs are presented in the software."
"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."
"Some of the support documentation seems to make assumptions that the person installing or configuring is experienced with the product or concepts."
"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 configuration of the basic services is pretty straight forward but for more complex solutions, there needs to be better documentation or knowledge base articles."
"We have experienced at least one problem with stability, although it was fixed with an upgrade."
"Some documentation is out of date versus the new version, and things have been moved​."
 

Pricing and Cost Advice

"There are additional costs depending on what modules or what functionality is required."
"BIG-IP LTM is considered a premium product, so it's quite expensive and isn't affordable for all customers."
"It is sort of a commodity product. A load balancer is a load balancer. What will be, at the end of the day, the cheapest option or have the best performance, that is what it will come down to."
"LTM is a good product, but it's expensive. They should make it more competitive because cloud providers offer free load balancing. Cloud providers can't cover all the security aspects of F5, but you get a decent amount of security. Cloud environments are becoming the norm across the IT industry. Many of the larger companies that previously used on-prem infrastructure are switching to the cloud, so companies like Fortinet and Palo Alto are reducing their prices. Otherwise, they can't compete in the cloud."
"We are on an annual license to use the solution."
"If your IT budget is good, go for it."
"The price of F5 BIG-IP Local Traffic Manager (LTM) is too high."
"Though functionality is high, its cost can be considered slightly higher than its competitors​."
"Licensing is yearly and I am going to guess that it is CAN $2000.00."
"Setup is easy, the cost is affordable, and the licensing is quick and simple."
"It has a very attractive ratio of price/performance."
"Download Kemp's VLM trial and take it for a test drive; you will be impressed."
"The price is lower than other options."
"Nowadays, going with the virtual appliance is the easiest way and the cost is reasonable."
"The costs for the Kemp Load Balancer solution are okay because, for a good product, you have to spend money."
"​I have control on the licensing and all the prices since I work for a partner.​"
