Barracuda Load Balancer ADC vs. Imperva Web Application Firewall (WAF)

Barracuda is an inexpensive solution for load balancing web traffic of all kinds and works as a reverse proxy if you need one. It is efficient and has been a very stable solution. If you need extremely granular configuration for your load balancing traffic, then you may need to go with one of the bigger brands. Barracuda will more than handle regular small and medium business use and do so at a greatly reduced price point.

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.

• Excellent Load Balancing.
• Flexible configuration - It's very simple to configure and powerful enough to handle many more websites than just our exchange site.
• Continuously updated - Barracuda makes fairly frequent updates to address issues and improve features.

• 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.

• Overall, there are no issues. It just runs.

• The UI can use a little work (but is largely decent)

It is a product we plan on continuing to use.

It is fairly easy to learn after support helps you set it up and shows you how things work. Which they will do.

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.

It did well for basic needs but would not deliver for all our services.

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).

We also had looked at Kemp and F5. The Kemp and F5 had a lot of horsepower and advanced configuration and functionality. When we looked at our workload and how we were planning on using the load balancers, we really didn't need all those extra bells and whistles. Barracuda provided all the standard functionality we needed and were looking for and did so at a greatly reduced price point.

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.

• It has allowed us to maintain a very high level of uptime.
• It has allowed us to perform server updates without the downtime of services.
• It has provided a consistent user experience by properly balancing service loads across servers.

• Meet compliance requirements - Check.
• 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.
