Centralized web firewalling has reduced our attack surface and protects multi‑cloud applications
AWS WAF can be improved by not being too sensitive for some data because with some XML, it is sometimes very sensitive. When we upload videos or photos, it is flagged as a malicious pattern, and sometimes it is not sensitive enough because some query patterns that have the capability to perform malicious actions still result in false positives from AWS. It would be better for AWS WAF if it not only had logs but also specific payloads or something that directly included the specific logs so we can have more detail in our analysis. I think it should be better if they improve their capabilities in reducing the attack surface and also have better visibility for OWASP top 10 web applications and the API. Regarding AWS WAF's AI capabilities, its governance and security are very good because our attack surface is mostly reduced. The new dashboard is a bit complicated; it is easier for non-technical users, but for technical professionals, it is sometimes confusing. While the security itself is good and the governance is good, I think it needs to improve the UI or the flow itself. The accuracy and reliability of AWS WAF's output is better than others. With the free version, it has a good filter with the attack surface and the reliability is good, but sometimes we need to adjust. With the free version, we also have to pay some amount of money if the number exceeds the default provided by AWS.

Geo-localization and IP reputation help to keep our clients secure and more available
The area that should be improved is licensing. When using an active/passive cluster, we have to pay 70% of the master appliance and license for the passive server that does not work. Since we know that only one server works at a time, we should pay only one license for the appliances and for the support as well. In my opinion, this has to be improved. If possible, the client software should be a web application instead of downloading software for the management. This can avoid login problems when they update or patch.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I would recommend the product because it is very flexible and you are able to use it with multiple services within AWS."
"Their technical support has been quite good."
"The agility is great for us in terms of cloud services in general."
"We do not have to maintain the solution."
"The most valuable features of AWS WAF are its cloud-native and on-demand."
"The ability to take multiple data sets and match those data sets together is the solution's most valuable feature. The data lake that comes with it is very useful because that allows us to match data sets with different configurations that we wouldn't normally be able to match."
"It's simple, easy to use."
"As a basic WAF, it's better than having nothing, so if you need something simple out of the box with default features, AWS WAF is good."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."
 

Cons

"The product should improve the DDoS-related features."
"We don't have much control over blocking, because the WAF is managed by AWS."
"Compatibility and integration functionalities, especially with services like Kafka for event-driven messaging, could be better."
"Support wise, I don't think they are that good compared to individual vendors."
"The solution's pricing could be improved."
"The serverless product from AWS WAF could be improved. For example, they have only one serverless series, Lambda, but they should extend and improve it. Additionally, the firewall rules are not very easy to configure."
"It's a bit difficult to apply the right rules for the right security."
"The pricing model is complicated."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"There are no separate licensing costs we pay for since it is included in the plan we purchase."
"It's cheap."
"We are kind of doing a POC comparison to see what works best. Pricing-wise, AWS is one of the most attractive ones. It is fairly cheap, and we like the pricing part. We're trying to see what makes more sense operation-wise, license-wise, and pricing-wise."
"It's an annual subscription."
"The pricing is good and manageable."
"AWS WAF has reasonable pricing."
"Its price is fair. There is a very fair amount that they charge. It has a pay-as-you-go model, so it pretty much depends on how much a user uses it. As per the cloud norms, the more you use, the more you pay. I would rate it a five out of ten in terms of pricing."
"The pricing should be more affordable, especially as it pertains to small clients."
