Effective network and DDoS protection with suitable pricing
I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

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.

Quotes from Members

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

Pros

"The DDoS protection features are valuable."
"This is a hybrid solution."
"I like the fact that the product provides a hybrid solution."
"The most important aspect, in general, is that the price is suitable for most clients."
"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."
"It is a very efficient and robust appliance."
"Rate limiting is a good feature that protects from volumetric attacks."
"Its initial setup process is straightforward."
"In summary, this solution is easy to manage, quick to deploy, and all of my customers are happy."
"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."
"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."
"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."
 

Cons

"Lacks international presence."
"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."
"I'd like to see an increase in Corero's international team. Our clients are generally companies with an international presence and Corero is not represented in all the countries where our clients have presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"The product must provide more Layer 7 capabilities."
"Juniper is known in our country, but it is not very popular."
"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."
"It could use support in Spanish."
"The product should provide improved bot detection and management."
"Another downside of Fastly is that when we wanted to migrate our API domains, it's lacking the WebSocket protocol."
"What I don't like about Fastly is that they charge a heavy price."
"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."
"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."
"Fastly's customer service area needs improvement."
"Support is not that great."
"The solution's pricing could be better."
 

Pricing and Cost Advice

"Its price is normal."
"The price of Corero is affordable."
"The pricing has been very competitive."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"The solution is cheaper than other products in the market."

"It is an expensive solution."
"You need to pay a premium price for the tool."
