Imperva Web Application Firewall (WAF) vs. NGINX Plus

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.

Makes our life easy as application admins in securing our applications and making them accessible. We can easily add an application within a few minutes and define the backend servers right away.

Incentivized

• 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.

Incentivized

• Load balancing
• Caching
• App security
• Boost App performance

Incentivized

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

• Update full config via api

No reason not to renew it, we are happy with it.

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's been great for us for 3+ years now.

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 had an issue after upgrading from RHEL 7 to 8, and there were some issues that the security team imposed upon the platform with a scanning tool. We also had a VXLAN environment that was not properly sending a gratuitous arp to the network. NGINX support was instrumental to speedily resolving our issue.

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.

The API and dashboard alone make NGINX Plus a better choice.

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.

Incentivized

• More uptime for business critical applications
• Less overhead for administrator to maintain the applications
