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.

Helps us to monitor attacks to our sites and prevents a lot of them

Set up Wallarm as a reverse proxy. Do not replace your web server. Use Wallarm first in monitoring mode, then learn from Wallarm which type of request is false positive and which type of request is not. This process takes a couple of weeks for very highly-loaded web applications (few millions of unique visitors in one month). Then you can turn Wallarm into blocking mode and everything will be fine. Do not forget to build a monitoring system, the wave, and API for it. Before we started using Wallarm, I already knew Ivan (CEO) and Stepan (COO) from a couple of years before. Ivan had his own security company and Stepan was working on a Russian security magazine called Xakep. They told us that they wanted to create a new WAF and already had a working version of it. They asked me to test it. We did tests, and it was really good. After few month after testing, we signed an agreement. Our choice was made not because we knew these guys for a long time, but because the product was really cool and we were glad to start using it as one of the first on the market!

Quotes from Members

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

Pros

"The product helps our organization to access sites located in different regions quickly."

"Fastly provides CDN, WAF, image optimization, and IP restriction."

"Compute@Edge features are valuable to me."

"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."

"Fastly has positively impacted my organization by helping to obtain better solutions in less time and in a much more traceable way."

"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."

"Its initial setup process is straightforward."

"Rate limiting is a good feature that protects from volumetric attacks."

More Fastly pros

"Vulnerability scanner and WAF are valuable features."

"The most powerful feature is the ability to first learn what type of query to make to your web application when it is attacked and what type of query creates a false positive to your app."

"They are the only solution that fits our success criteria and business objectives: WAF must have a low (<5%) false negative rate and be ready to protect from all well-known web attacks."

"Helps us to monitor situation in regards to attacks to our sites and prevents a lot of them."

"With active threat detection, we are no longer over-swamped with tons of useless events."

"Perimeter control and active vulnerability scanner are the most valuable features."

Cons

"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."

"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."

"Fastly can be improved in certain areas such as VCL, which is powerful but has a steep learning curve for normal users."

"The solution's pricing could be better."

"Support is not that great."

"The product should provide improved bot detection and management."

"Fastly's customer service area needs improvement."

More Fastly cons

"The biggest problem for us was the stability and speed using the first version of Wallarm. Now, it is fine."

"Technical support is 6 or 7 out of 10. Sometimes we have had trouble with communication and understanding."

"It needs more customization in PDF reports."

"Wallarm uses a learning mechanism to detect attacks and to avoid false positives. If Wallarm blocks some illegitimate request, then you can go to the management console and mark this request as false positive, but sometimes this does not work properly."

"There were several stability issues during the first pilot."

Pricing and Cost Advice

"The pricing has been very competitive."

"Fastly is less expensive than one of its competitors."

"In my opinion, Fastly is priced competitively."

"It is an expensive solution."

"You need to pay a premium price for the tool."

"The solution is cheaper than other products in the market."

"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."

"Pricing must be cheaper than the competition and the licensing must be good."
