Barracuda Web Application Firewall vs. Imperva Web Application Firewall (WAF)

Easy to use and reliable, with very little maintenance required and zero downtime to date. For the education sector, ease of use is hugely important as IT Managers/Technicians are often "Jack of all trades" with a good, broad general knowledge but perhaps lacking specific expertise in certain aspects. Being provided with easy-to-follow tutorials and instructions has been very useful in setting up and configuring the firewall, especially as my background is more in desktop support.

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.

• Email Filtering and Inspection
• Web-based intrusions and attacks
• Traffic Patterns

• 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.

• Reports could be somewhat confusing.
• The initial setup was a little difficult for our Security Admin team.

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

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.

The Barracuda Web Application Firewall is easy to use. Support from Barracuda is great also. Load Balancing of the Web Application Firewall is also nice. This allows you to do maintenance or have large loads for the end-user. Threat monitoring of our network and traffic coming into our services within our cloud solution.

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 have used SonicWalls and WatchGuard firewall appliances neither are even remotely close to the Barracuda Web Application Firewall. In addition, Barracuda support is fantastic. Throw in the 4 year (free) refresh cycle and there is no reason we would even consider the other two again (at least for the foreseeable future).

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.

• Negative impact: a default port was open and missed by one of our techs.
• Positive impact: it protects us everyday now that we have it locked down.

• 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.
