Good feature set and is simple to deploy
In terms of what needs improvement, the price could be lowered. We've tried to deploy more of them but our purchasing department has said that they're way too expensive and they would prefer to use something else. We sort of stopped deploying them because of that. There are additional costs to the standard licensing. There are bandwidth prices. The feature set is quite good. We've been told to stop using them because of the price. If they can do something to address that I believe it would be better. On the latest version they've got a community edition, which is quite a good bandwidth, but in essence, it's to address the entry-level price. When you get to 10 gig bandwidth, it's way too expensive.

Room for improvement with user interface while competitive pricing impresses
It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

Quotes from Members

Pros

"The most valuable aspect of this solution is that it is simple to deploy. The deployment took us ten minutes."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"The product's most valuable feature is its ability to set up the rules easily."
 

Cons

"In terms of what needs improvement, the price could be lowered. We've tried to deploy more of them but our purchasing department has said that they're way too expensive and they would prefer to use something else."
"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
