Kavin Kalaiarasu - PeerSpot reviewer
AWS's cloud-native security simplifies rule enforcement but needs better DDoS integration
The dashboarding could be improved, and the default metrics provided by AWS WAF could be upgraded. The rate at which AWS updates their managed rule sets could be better. Features like bot protection or DDoS mitigation, available with other WAF vendors, do not come natively with AWS WAF. Instead, they are part of AWS Shield. Providing DDoS protection as part of their WAF solution would be beneficial.

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

"As a basic WAF, it's better than nothing. So if you need something simple out of the box with default features, AWS WAF is good."
"AWS WAF helps mitigate different kinds of bot attacks and SQL injection that happen within the retail industry."
"The most valuable feature is the way it blocks threats to external applications."
"AWS WAF is a stable solution. The performance of the solution is very good."
"We integrate AWS WAF with several platforms within cloud hosting and other security solutions and provisions in our business. Regarding AI, it's been around for about 20 years, so it's not new. It's just a new buzzword. I've been in security for 30 years and remember using AI when I started 25-30 years ago. We have multiple forms of AI within our business."
"The tool’s stability is very good."
"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."
"Some valuable features of AWS WAF include its seamless integration and ease of orchestration within the AWS platform."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"They should work to define more threats, add more security, and make it more compliant with more security companies."
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"We should be able to do proper whitelisting."
"Compatibility and integration functionalities, especially with services like Kafka for event-driven messaging, could be better."
"One area that could be improved is the DDoS protection."
"When users choose the free service, there isn't great support available to them."
"The product could be improved by expanding the weightage units of rules."
"The product should improve the DDoS-related features."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"It's an annual subscription."
"The price is average."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven or eight out of ten."
"For our infrastructure, we probably pay around $16,000 per month for AWS WAF. Because alternative WAF solutions provide even more features, I think the AWS WAF is a bit pricey"
"AWS WAF is pay-as-you-go, I only pay for what I'm using. There is no subscription or any payment upfront, I can terminate use at any time. Which is an advantage."
"The solution's cost depends on the use cases."
"AWS WAF costs $5 monthly plus $1 for the rule. It's cheap, cost-wise. It's worth the money."
"The solution is affordable."
