Imperva web application firewall does a great job in giving us control over access to our public web servers. With our regular hosting provider, we couldn't block access based on geography, or really anything. So we had to rely on traditional access controls to protect the data. But with the WAF, we can block countries such as North Korea, or we could stop any SQL Injection attempts, or even do a temporary block of IP in the case of detected brute-forcing.
Loadmaster is very powerful and flexible load balancer. Variety of options allows to create a complex network of rules and routes. During our website rollout Loadmaster allowed us to run multiple generations of the website simultaneously and seamlessly by doing the content switching on the fly. Powerful API allows easy integration into any development lifecycle.
Alert Aggregation - Correlates different violations into perceived correlated attacks.
Ease of deployment - as one of the only WAFs that allow bridge mode deployment, this can be deployed with without downtime and no Network Architecture modifications. If the need for proxy is required at a later time, Transparent Reverse Proxy can be deployed within seconds and minimal configuration.
Custom Policies - Custom security policies are easy to configure.
Reporting - There are a good amount of pre-configured reports available by default.
Where the LoadBalancer excels is the multiple levels at which you can load balance servers. We currently use layer 7 LB, but others are available as well.
I particularly like the ability for the LB to know when servers are down, and if all are offline then you can create a redirect to a static HTML page or some other destination that is more informative.
The ease in which a service can be created and deployed using already pre-canned templates makes it a very convenient setup process.
There are just a couple of points that are hard to find, that probably could be elsewhere. But these are minor; everything else is right where you'd expect it to be.
Kemp makes it very easy to setup, configure and manage the LoadMaster without needing a lot of help from their engineers. The interface is very easy to understand and intuitive to use. We like how it is not complicated - I can easily have one of my techs login and they can figure out how to setup/configure virtual services for load balancing without needing a manual or tech support.
We haven't needed support from Imperva since implementation. But during that time, their personnel were very quick to respond to questions. Since then, it's been largely doing its thing for us (which is exactly what we'd hoped).
Support has been easy to deal with; I have only need[ed] to contact them a few times during setup. Once its been in place and operational, we have not need[ed] to mess with the system [which] is a huge advantage. I like system[s] that do not break and require constant attention in a production environment.
Ultimately, it was the easiest to work with that was still a "known" company (we've been burned too many times by up-and-comers). We needed something that gave us a lot of control but then didn't need its handheld on a daily basis. Imperva gives us a lot of that and we are still able to navigate it with ease.
We chose Kemp LoadMaster because it is 1/10 the price of the competition and MUCH easier to deploy and configure and WORKS. We have had ZERO issues with the product since installation. Their engineers and their sales team have both reached out post-install to check in and see if everything is working as expected.
Better Insight into web application - Absolutely great, checks all the traffic against RFC standards and will alert on common development mistakes that duplicate application traffic or provide attack vectors for potential attackers.
Have had several issues blocking a customer without producing alerts, while it happened only one week out of 2 years of working with the devices, it did produce a lot of headaches.
We used Kemp LoadMaster for many projects. For a lot of customers, load balancers were too expensive or too complicated before we introduced Kemp products.
It's not a overly complicated product, so we were able to train many engineers on it and have them get a certification.
