Patel Parth
Technical support engineer at Adobe
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.

Cons

"Fastly's customer service area needs improvement."
"Support is not that great."
"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."
"The product should provide improved bot detection and management."
"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."
"What I don't like about Fastly is that they charge a heavy price."
"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 primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."
"There aren't really any aspects of the solution we are unhappy with. It's been a positive experience overall."
"I would like to see analytics, big data."
"Alerts and reporting features must be improved."
"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."
"The web interface could be much better."
"All the thresholds that need to be configured should be included in the default so that user will not forget or misconfigure."
"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."
