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

"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."
"The customizable features are 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."
"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."
"We preferred the product based on its cost. AWS WAF is an out-of-the-box solution and integrates with the AWS services that we use. It's natively integrated with AWS."
"Stable and scalable web application firewall. Setting it up is straightforward."
"Their technical support has been quite good."
"The most valuable feature of AWS WAF is its highly configurable rules system."
"The product's initial setup phase is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Compute@Edge features are valuable to me."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"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."
"Its initial setup process is straightforward."
"The product helps our organization to access sites located in different regions quickly."
 

Cons

"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."
"For now, there is no feature to protect against attack of the bad bots"
"The cost management has room for improvement."
"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."
"It would be good if the solution provided managed WAF services."
"The dashboarding could be improved, and the default metrics provided by AWS WAF could be upgraded."
"While the complexity of the installation can vary from one service to another, overall, I would say that it and the configuration and navigation are somewhat complex."
"On the UI side, I would like it if they could bring back the geolocation view on the corner."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"What I don't like about Fastly is that they charge a heavy price."
"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."
"Support is not that great."
"Fastly's customer service area needs improvement."
"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."
 

Pricing and Cost Advice

"It has a variable pricing scheme."
"You need an additional AWS subscription for this product if you are buying a managed tool."
"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."
"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."
"There are different scale options available for WAF."
"It's an annual subscription."
"The solution is affordable."
"It's cheap."
"Fastly is less expensive than one of its competitors."
"It is an expensive solution."
"The solution is cheaper than other products in the market."
"You need to pay a premium price for the tool."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"The pricing has been very competitive."
"In my opinion, Fastly is priced competitively."
