AWS WAF
AWS WAF is highly appropriate to interrupt or prevent cyber attacks because when implementing rules, whether they are specific or centralized, so any application that has these vulnerabilities is protected.
Implementing managed rules creates greater security to protect both API and applications.If implemented along with other AWS tools, the security is much better, so if you want to protect applications against more specific attacks, it is ideal to integrate with Amazon CloudFront, which is a great benefit because it warns when thresholds are exceeded or specific attacks occur.AWS WAF is ideal to avoid common web attacks. For more specific attacks and scenarios, I don't recommend this.

Imperva Web Application Firewall (WAF)
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.

Pros
AWS WAF
- AWS WAF has the most developer-friendly API to create firewall rules.
- AWS WAF provides OWASP security controls, which reduces developers' burden (i.e., SQL injection and cross-site scripting).
- AWS WAF has customizable web security rules. The user can even push the rules through the API available, which is the great feature and helped me a lot.
- It protects applications at layer 7 (HTTP) of the OSI model and not just layer 4 (TCP).

Imperva Web Application Firewall (WAF)
- 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.

AWS WAF
- The documentation offered is somewhat confusing, so it would be ideal if it were much more direct and precise.
- Your initial configuration may be confusing, so the best option is to use the rule templates provided by AWS.
- Its configuration is not unified with AWS, so it must be done separately and it takes some time.
- The number of rules to be established is somewhat limited.

The product is highly scalable. It is easy to configure the rules and thereby helps us to mitigate many vulnerabilities.The interface and programming of the firewall provisions were easy to setup. Amazon clearly spent a lot of time figuring this out and perfecting it. It allows users to do customized configurations based on their needs. It provides protection against a number of security issues like XSS, SQL injection, etc. I would definitely recommend this for protecting your infra as you scale, since this basically protects and filters all requests hitting your application server.

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.

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).

Alternatives Considered
AWS WAF
We evaluated Imperva, but we were more convinced with AWS WAF because of the better pricing model, ease of deployment as we were already using the AWS platform which helping in ease of integration. The technical support for AWS WAF seemed to be better as they had better understanding of the overall system and architecture of the product, which helped us in getting a problem solved that was encountered while using AWS WAF. The amount of documentation and helpful material available online for AWS WAF made it the first choice for us to select this product over Imperva.

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.

Return on Investment
AWS WAF
- Our applications are less exposed to cyber attacks, which prevents them from getting out of control and consume much more resources than they should.
- Saved us money by preventing attacks.
- The traffic control is much more bearable.
- App development is safer.

Imperva Web Application Firewall (WAF)
- 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.
