Featured Reviews

Archana Heeralal - PeerSpot reviewer
A good solution to implement web application firewall for applications
There are some lags in Signal Sciences for the web application firewalls. Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic. There is a little bit of complexity with custom rules that should be removed. Signal Sciences should add a feature called rate limiting with multiple options, wherein I can create a rate limiting based on the cookie request or the IP.
Eduardo Oviedo-Blanco - PeerSpot reviewer
A CDN solution to enhance loading times and streamline navigation
When one of the primary nodes spanning from North to South America, from the northern US to the southern US, became operational, it had a big impact. It can be challenging to explain its advantages to clients. The technical nature of the marketing material is too technical for stakeholders. Integrating the solution was straightforward, requiring no extra effort. Edgio Global CDN operates, resembling familiar cloud services but offering elevated functionality. Unlike platforms such as Google Cloud Platform or RIN geared towards development teams, Edgio emphasizes client-facing services that are integral to our operations. Overall, I rate the solution a nine out of ten.

Quotes from Members

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

Pros

"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."
"The product's most valuable feature is its ability to set up the rules easily."
"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 Rules Engine V4 is the most valuable feature."
"The product is easy to use and easy to implement."
"The customer support and service responsiveness were excellent."
"It's super easy to use and integrate with."

Cons

"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."

"The web interface of the Verizon Edgecast portal is very old. It's not user-friendly, slow, and it is missing some valuable features like the ability to make bulk changes."

"In the next release, I would like to see more global endpoints for their CDN and a lower price."
"We could not create more than 15 custom rules."
 

Pricing and Cost Advice

"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
