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

"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."
"We are in touch with their team, and they are very collaborative."
"Kemp has greatly improved our uptime, reduced time we spend on maintenance, and increased the reliability and trust we have in our load balancing system."
"Failover is seamless and our services are rock solid."
"The feature that allows us to easily disconnect a server when we need and bring back online is the most valuable. It's a click of a button. This allows us to keep all systems up. We can then run updates, perform reboots whatever we need to one of the servers without taking production down."
"We needed a Microsoft Threat Management Gateway server replacement solution for a customer and were impressed with the simplified deployment of the Kemp LoadMasters."
"Having a reverse proxy is a secure way to protect access to inside services like Microsoft Exchange."
"The most valuable features are synchronizing email with mobile devices and synchronizing with Outlook."
"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."
"It seems to provide a bit of useful information on website health."
 

Cons

"When we go serverless, we may again have to revisit this because the configuration needs to be changed. With this change, we can run into a lot of other configurations that we haven't got into, which involve additional expenses. It would be challenging to convince management to buy at that price point. It would be a balancing act of justifying that expense and the value, that is, how it is going to save a bit of time and make our platform secure. It can have better configuration ability. A lot of iterations happen when we have multiple servers pointing to the same domain. If we do not orchestrate carefully, it gets into a loop, which takes away the precious time of the user who is trying to subscribe to a service. It takes a little longer time to realize services as well as web pages."
"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."
"I would say overall improvement of the solution features"
"Several elements of the GUI need work. For example, if you have many content switches, it’s difficult to find the ones you need. And where is the search feature?"
"On the improvement side my comment would be about the equivalent hardware based LM (LM-X1) to offer redundant power supply like the more beefier KEMP models do."
"If I had to pick an area for improvement, I think it would be direct integration with the template library."
"The configuration of basic services is pretty straightforward but when you want to configure more advanced settings like the Edge Security Pack feature, it can be somewhat challenging."
"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."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"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.​"
"The price is great and the value is definitely there."
"It has a great price for the solution they offer."
"Licensing is yearly and I am going to guess that it is CAN $2000.00."
"It is well-priced and licensing is very flexible."
"The price is lower than other options."
"Pricing for the perpetual licensing was fair to us for the features and ease of use we received."
"The pricing is alright and we pay a monthly licensing fee"
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
