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.

Optimized ecommerce performance and improved access control through image handling and IP filtering
I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

Quotes from Members

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

Pros

"AWS WAF has helped to strengthen the security of my environment; it has also helped to improve the posture of our application, prevent all DDoS attacks and unnecessary traffic and SQL injection that is reducing the performance of our application."
"What I like best about AWS WAF is that it's a simple tool, so I could understand the basics of AWS WAF in two to three hours."
"Rule groups are valuable."
"The tool’s stability is very good."
"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 cloud-native nature of AWS is crucial since most of our workload is in AWS, making AWS WAF native to Amazon Web Services."
"The solution is stable."
"It is a one-click WAF with no effort needed."
"Compute@Edge features are valuable to me."
"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"Rate limiting is a good feature that protects from volumetric attacks."
"The product's initial setup phase is straightforward."
"The product helps our organization to access sites located in different regions quickly."
"Its initial setup process is straightforward."
 

Cons

"The pricing model is complicated."
"The solution should identify why it blocks particular websites."
"It would be good if the solution provided managed WAF services."
"The solution is cloud-based, and therefore the billing model that comes with it could be more intuitive, in my opinion. It's very easy to not fully understand how you tag things for billing and then you can quite easily run up a high bill without realizing it. The solution needs to be more intuitive around the tagging system, which enables the billing. Right now, I have a cloud architect that does that on our behalf and it isn't something that a business user could use because it still requires quite a lot of technical knowledge to do effectively."
"The default content policy available in the tool is not very strong compared to the competitors."
"Technical support for AWS WAF needs improvement."
"They should make the implementation process faster."
"An improvement area would be that it's more of a manual effort when you have to enable rules. That's one of the downsides. If that can be done in an automated way, it would be great. That's a lagging feature currently."
"Fastly's customer service area needs improvement."
"What I don't like about Fastly is that they charge a heavy price."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"The solution's pricing could be better."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"The product should provide improved bot detection and management."
"Support is not that great."
 

Pricing and Cost Advice

"The solution's cost depends on the use cases."
"I would rate AWS WAF's pricing a seven out of ten."
"It's quite affordable. It's in the middle."
"The price is average."
"It's an annual subscription."
"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."
"AWS WAF has reasonable pricing."
"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."
"You need to pay a premium price for the tool."
"In my opinion, Fastly is priced competitively."
"It is an expensive solution."
"The solution is cheaper than other products in the market."
"The pricing has been very competitive."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"Fastly is less expensive than one of its competitors."
