Featured Reviews

Pranay Jain - PeerSpot reviewer
Senior software engineer at Simplify vms
Edge caching has transformed response times and delivers faster candidate data globally
Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users. A more user-friendly, UI-based configuration could simplify the experience, alongside better templates for common use cases and dashboard improvements, as the current dashboard feels complex for beginners, and pricing can be hard to predict for smaller companies. I chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities. However, VCL complexity and pricing predictability, especially for smaller companies, along with a user-friendly dashboard are areas impacting my score.

Provides automated protection against web attacks and simplifies deployment with cost-effective pricing
Radware Kubernetes WAF protects our web applications from web-based attacks like SQL injection and cross-site scripting. It provides automation capabilities. For example, if a DDoS attack is happening, it automatically recognizes the attack and prevents it accordingly. Radware Kubernetes WAF provides automation that is effective in dealing with security threats.

Quotes from Members

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

Pros

"The product's initial setup phase is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"Fastly provides CDN, WAF, image optimization, and IP restriction."
"Compute@Edge features are valuable to me."
"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 has positively impacted my organization by helping to obtain better solutions in less time and in a much more traceable way."
"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."
"Initially, we faced load time issues, but after deploying Fastly and optimizing our queries, we achieved a response time cut to less than 1 millisecond from an initial 3 to 4 seconds."
"I would give Radware Kubernetes WAF a rating of 10 out of 10."
 

Cons

"The product should provide improved bot detection and management."
"Support is not that great."
"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."
"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."
"The solution's pricing could be better."
"I think Fastly could improve by improving the documentation and having some code examples so that it is easier for developers, since at the beginning it becomes a bit complicated."
"What I don't like about Fastly is that they charge a heavy price."
"If Radware provides a separate web service like those offered by vendors such as F5 and Imperva, that would be better."
 

Pricing and Cost Advice

"The solution is cheaper than other products in the market."
"In my opinion, Fastly is priced competitively."
"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 pricing has been very competitive."
"You need to pay a premium price for the tool."
