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

"The interface is good."
"I believe the most impressive features are integration and ease of use. The best part of AWS WAF is the cloud-native WAF integration. There aren't any hidden deployments or hidden infrastructure which we have to maintain to have AWS WAF. AWS maintains everything; all we have to do is click the button, and WAF will be activated. Any packet coming through the internet will be filtered through."
"The most valuable feature is the way it blocks threats to external applications."
"The tool’s stability is very good."
"The most valuable feature of the solution is the ability to integrate central sets. It protects from intrusion attacks such as scripting and SQL injections."
"We can host any DB or application on the solution."
"One common use case is using detection protection for enhancing security models in AWS. Another use case is implementing log analysis and response recovery procedures for email services."
"The customized billing is the most valuable feature."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The product's initial setup phase is straightforward."
"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."
"Compute@Edge features are valuable to me."
"Its initial setup process is straightforward."
"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."
 

Cons

"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."
"The user experience, the interface, is lacking. Sometimes it's hard to find certain areas that it has alerted on."
"There is room for improvement in pricing."
"They have to do more to improve, to innovate more features. They need to increase the security. It has to be more active in detecting threats."
"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."
"We need more support as we go global."
"The default content policy available in the tool is not very strong compared to the competitors."
"One area for improvement in AWS WAF could be the limitation on the number of rules, particularly those from third-party sources, within the free tier."
"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."
"The solution's pricing could be better."
"Support is not that great."
"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."
"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."
 

Pricing and Cost Advice

"The pricing is good and manageable."
"It's quite affordable. It's in the middle."
"AWS is not that costly by comparison. They are maybe close to $40 per month. I think it was between $29 or $39."
"The solution's cost depends on the use cases."
"AWS WAF has reasonable pricing."
"You need an additional AWS subscription for this product if you are buying a managed tool."
"There are no separate licensing costs we pay for since it is included in the plan we purchase."
"It has a variable pricing scheme."
"Fastly is less expensive than one of its competitors."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"It is an expensive solution."
"The solution is cheaper than other products in the market."
"The pricing has been very competitive."
"You need to pay a premium price for the tool."
"In my opinion, Fastly is priced competitively."
