Has successfully filtered malicious traffic and allowed country-specific access controls
For improvement in AWS WAF, we can have better monitoring. One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from. If it's a bot, we should differentiate the requests, whether they are automated or not. The way we see it now is just mentioned as a percentage from bots and actual users, which should include proper graphs and detailed information. We also need a feature where we can filter specific requests. If there are scripts in the requests, we should be able to filter those requests to see if there are any scripts running from them.

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

"The performance is excellent."
"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."
"We have received good support from the customer service and support team."
"The biggest benefit of AWS WAF for us is to filter malicious requests, so we can protect our environment and application from malicious actors."
"The most valuable feature of AWS WAF is its highly configurable rules system."
"It's simple, easy to use."
"The agility is great for us in terms of cloud services in general."
"AWS WAF has a lot of integrated features and services. For example, there are security services that can be integrated very well for our customers."
"By publishing the application without fear, my customer has created new revenue by making the website available anytime and anywhere."
"The three most valuable features that I noticed are the geo-localization of the user, the IP reputation, and the compartmental analysis."
 

Cons

"I'd like to see improvements in its usability and functionality. I'm also concerned about being too dependent on the cloud provider's WAF version. For security, using multiple vendors and not putting all our eggs in one basket is better."
"The solution should identify why it blocks particular websites."
"The technical support does not respond to bugs in the coding of the product."
"I would like to see it more tightly integrated with other AWS services."
"One of the things that should be improved in AWS WAF is the monitoring; we need to identify the requests and where they are coming from."
"We should be able to do proper whitelisting."
"This solution could be improved if the configuration steps were more specific to WAF, compared to other cloud services."
"AWS WAF would be better if it uses AI or machine learning to detect a potential attack or a potential IP that creates an attack even before it happens. I want AWS WAF to capture the IP and automatically write the rule to automate the entire process."
"The area that should be improved is licensing."
 

Pricing and Cost Advice

"It has a variable pricing scheme."
"AWS WAF has reasonable pricing."
"The pricing should be more affordable, especially as it pertains to small clients."
"It's quite affordable. It's in the middle."
"I rate the product price a five on a scale of one to ten, where one is high price, and ten is low price"
"The price of AWS WAF is expensive if you do not know how to manage your software up or down. I price of the solution is average amongst the other competitors but it would be better if it was less expensive."
"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."
"It's an annual subscription."
