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.

I recommend Imperva specially if you have a big environment with thousand of websites because of its ease to use and availability. Imperva delivers a reliable solution with great capability to contain cyber attacks and even fraud preventions in some cases. The only scenario it's less appropriate is if your focus is anti fraud instead of a solution to block cyber attacks.

• Attack patterns are regularly updates through contents via Barracuda Web Application Firewall update servers
• Bot Protection has a good line feature to verify between the genuine clients like browsers and bots
• Dos Protection also good level of protection to mitigate Layer 7 attacks
• Allow Deny Rules provides a lot of granular controls to allow and deny the traffic
• URL profiles has a very granular control to mitigate false positives
• Parameter profiles has a very granular control to mitigate false positives
• Risk score feature for the clients to mitigate attacks is also very good feature
• Client fingerprint module can be used against malicious user to enhance security
• Separate XML and JSOn profile for all the URL profiles of the application is plus
• API security is very much effective and shadow API can also be identified

• Block some dynamic attacks such as SQL injection.
• Block unfriendly accesses based on geographic source.
• Helps us implement SSL in cases where the original server can't (yet).

• STM crashes sometimes happen due to unusual traffic pattern
• Obfuscation on the client side user credentials which appears in the developer tools of browser
• URL Profiles redundancy during the learning of traffic needs to be fixed
• Dos Protection should be more granular like escalation period to throw JS challenge, Captcha and rate limit when escalation period hits until the WAF stops the attack
• Client Fingerprinting should work as expected when verifying the clients as in rare some scenarios, it creates issues

• Attack Correlation Validation - This specific policy produces a lot of false positives as well as the SQL injection policies. Of course it is difficult to tell what a legitimate query is on a public facing web app.
• Profiling - I tend to spend more time than any other feature tuning the Web App Profiles. Plugins are used to help cope with this, but on extremely large web apps we are forced to turn off the profiling feature.

-User friendly interface for quick learning -Quick deployment for deploying applications -Easy to manage for naive -System components and upgradation of the WAF is very easy go with -Back restoration is very to make it up and ready anytime -Seperate JSON and XmL profiles for each URLs of the application is plus -Amazing and world class support engineer in comparison other vendors and always available to support -Quick resolution on bugs with their patch applying process

It's easy and works great. The onboarding process, although easy, can sometimes take too long for SSL and domain validation, but its not a big deal.

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 been using their Backup products especially Backup Appliances and legacy products like Intronis. We are also using their Cloud Backup Solutions for O365. This is the reason we opted for this product.

I believe there's no comparison as Imperva is a much more reliable and powerfull WAF. AWS WAF lacks of several features Imperva have and is not that simple to configure neither have a clean web console. I consider Imperva WAF a whole superior level of cyber security solution and it's consider to be one of the leader in this segment.

• Much better response times for remote transactions
• 4 year refresh cycle included with active support contracts
• More expensive than traditional firewalls (however its superior to those, not apples to apples)

Incentivized

• 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.
