Reliable protection ensures robust network defense and simplifies DDoS management
I am not sure if we plan to use additional features because we have many vendors and platforms that we support. We use the main function and that is it. The prices for Arbor DDoS are expensive. The licensing is subscription-based. From our sales department, they discuss that prices are very high. A potential improvement could be establishing a contract with Cisco to sell via their channel. This could be beneficial because we work extensively with Cisco. If you are a Cisco partner, you can sell Arbor DDoS. That would be good for customers that are Cisco-based because many customers in Bosnia are Cisco-based customers. BH Telecom, our main customer, sells Arbor DDoS to other customers for protection. They buy Arbor and sell the product services to others via Internet links. They sell add-on DDoS protection via Arbor DDoS. In Bosnia and Herzegovina, Arbor DDoS is not present in many customers. Some customers try to sell it, but they sell other vendors such as F5. Arbor DDoS is mainly seen in telecom operators but not much in other customers.

Optimized ecommerce performance and improved access control through image handling and IP filtering
I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

Quotes from Members

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

Pros

"The solution is easy to use."
"Our customers are very happy when we provide them with the interface... They can check how many attacks they have faced and how many attacks have been blocked."
"It's just one dashboard with mitigation. You decide which mitigation you want and at what threshold to do this or that. Its operation is pretty simple. It's easy."
"The solution looks into volumetric attacks and gets them resolved."
"The stateless device format means that the box is very strong for preventing DDoS attacks."
"The product allows us to check real-time progress, including latency and network activities."
"Predefined filters/techniques to easily stop the attacks and start mitigation."
"Arbor has the ability to learn and self-create the appropriate profile for each customer."
"Rate limiting is a good feature that protects from volumetric attacks."
"Its initial setup process is straightforward."
"The product helps our organization to access sites located in different regions quickly."
"The product's initial setup phase is straightforward."
"Compute@Edge features are valuable to me."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"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 provides CDN, WAF, image optimization, and IP restriction."
 

Cons

"There is definitely room for improvement in third-party intelligence and integrations."
"An improvement would be to provide information on how pricing is done on different customer levels."
"The product could have end-to-end platform visibility."
"There is some room for AI to take place."
"The prices for Arbor DDoS are expensive. The licensing is subscription-based."
"The upgrade process is mildly complex requiring treatment of the custom embedded OS separately from the application. The correlation of the underling OS to the application version can be easily missed."
"The regional support here in African could improve, such as marketing and account managers."
"Based on my experience and feedback from colleagues, Arbor can make better use of the product because you have to spend a lot of time finding information in a huge number of papers."
"Fastly's customer service area needs improvement."
"The product should provide improved bot detection and management."
"Support is not that great."
"The solution's pricing could be better."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"What I don't like about Fastly is that they charge a heavy price."
"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."
 

Pricing and Cost Advice

"I don't deal with the pricing, but it seems that you need to get basic support in order to upgrade the software and implement some patches."
"Our customers always complain about the price of the product."
"Arbor is striking a good balance between pricing and what they deliver."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
"As far as I know, they are the best in this sector, in DDoS protection. They know it, I know, because their service prices are too high. They provide cloud DDoS protection for ISPs, but that is also too expensive."
"The solution is a bit costly if you're a small organization, but I think it's worth the price that they are charging."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
"Arbor DDoS is quite expensive, but all these solutions are expensive because they deal with confidential information."
"It is an expensive solution."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"You need to pay a premium price for the tool."
"In my opinion, Fastly is priced competitively."
"Fastly is less expensive than one of its competitors."
"The solution is cheaper than other products in the market."
"The pricing has been very competitive."
