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

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

Quotes from Members

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

Pros

"Security is considered the most effective feature in Kemp LoadMaster."
"The most beneficial function of using the ADC is to ensure this resiliency."
"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 load balancer is stable and met the customer's expectations."
"Great web balancing and remote access balancing."
"The LoadMaster met all of the features and performance we were looking for at a very affordable price."
"It has been functional. We don't have any outages."
"Kemp stood out from day one, with a lot of flexibility in how you can deploy and purchase the products."
"It seems to provide a bit of useful information on website health."
"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."
 

Cons

"If you want logging for SMTP traffic, you have to enable ESP, which requires you to define allowed IP addresses. That’s irritating, to say the least."
"If there is one thing I would change is to have the license file not be coupled with the MAC address of the device."
"There are some challenges with updates on certain models that don't have a few features."
"I would say overall improvement of the solution features"
"The ability to see live traffic is not great and can be improved."
"Over the last several major versions, the GUI has remained virtually unchanged and still seems lacking."
"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."
"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."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"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."
"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."
"This is a cost-efficient product."
"Setup is easy, the cost is affordable, and the licensing is quick and simple."
"It has a great price for the solution they offer."
"The pricing is alright and we pay a monthly licensing fee"
"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."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
