Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Hamada Elewa - PeerSpot reviewer
Users have experienced comprehensive protection against DDoS threats while enjoying seamless integration
The most valuable feature of Arbor DDoS is that it is based in most of the ISPs all over the world, and Egyptian ISPs are one of them. If a customer who is getting internet connectivity from one of the ISPs has an Arbor at the end, it will be integrated with the ISP Arbor. It's some sort of closing all the cycle with Arbor DDoS, from the ISP sides and from your side as a customer. Traffic analysis with Arbor DDoS is very good; it is brilliant. They act in a different way compared to others, and the vendor support is very good. The main benefits Arbor DDoS provides to users include stopping DDoS attacks, which is the biggest nightmare for all customers.
Nick Wilsdon - PeerSpot reviewer
An easily scalable and stable product that provides exceptional support
The product should provide improved bot detection and management. The product should also provide support for code management. Everybody working in CDN is currently looking for ways to better manage code deployment with various authorization levels and synchronization with our lower environments. Matching up what's happening in CDN with what's happening on the origin regarding testing would always be useful.

Quotes from Members

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

Pros

"Cloudflare has many features."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"The solution provides good load balancing and protection against DDoS attacks."
"The tool is user-friendly."
"Arbor DDoS's best feature is that we can put the certificates in, and it will look at layer seven and the encrypted traffic and do the required signaling."
"We also use it by serving our customers' cloud signaling services with on-premise APS devices."
"Using standard BGP, NetFlow and SNMP ensure wide compatibility. There are also peering traffic reports that can help identify upstream peering opportunities. The ATLAS aggregation service allows us to contribute to the global DDoS data and benefit from overall trends."
"Its scalability is big. It is for large deployments of big organizations and service providers."
"The most valuable features include the traffic categorization and control of the traffic. The filtering of the traffic is very precise. When you want to stop some traffic, you precisely stop that traffic."
"Arbor has the ability to learn and self-create the appropriate profile for each customer."
"Valuable features include simple and centralized management of user access and capabilities, as well as Web 2.0 interactive attack alerting, traffic visualization, and mitigation service control."
"The product allows us to check real-time progress, including latency and network activities."
"Compute@Edge features are valuable to me."
"The product's initial setup phase is straightforward."
"Rate limiting is a good feature that protects from volumetric attacks."
"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."
"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."
"Its initial setup process is straightforward."
"The product helps our organization to access sites located in different regions quickly."
 

Cons

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"The pricing could be improved."
"The product needs to improve its automation."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Real-case scenarios that have taken too long to resolve or were escalated can be directly converted into articles."
"I think Arbor DDoS needs improvement in areas where competitors like S5, Redver, or NETSCOUT offer web application firewall functionality or dedicated web application firewall devices. Arbor lacks these features, which is a significant disadvantage. Yes, I would like to see these features introduced in Arbor as well. Regarding real-time detection capabilities, Arbor DDoS works very well. We and our customers are very satisfied with its performance. However, it would benefit from adding Web Application Firewall (WAF) capabilities to reach a larger customer base."
"The product could have end-to-end platform visibility."
"The support got worse after NETSCOUT acquired Arbor."
"They should improve the reporting section and make it a little bit more detailed. I would like to have much better and more detailed reports."
"When it comes to some false positives, we need to tweak the system from time to time. There is room for improvement when it comes to the actual mitigation because of some false positives."
"With Arbor DDoS, its integration issues with other technologies or other vendors' technologies is an area of concern that could be improved."
"The following areas need improvement: opening and tracking support tickets, online support resources, software upgrades/updates and replacement media, and event management guidelines."
"The product should provide improved bot detection and management."
"What I don't like about Fastly is that they charge a heavy price."
"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."
"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."
"Support is not that great."
"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."
"Fastly's customer service area needs improvement."
 

Pricing and Cost Advice

"The cost primarily depends on the size of the organization."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"There are no additional costs beyond the standard licensing fees."
"The tool is a premium product, so it is very expensive."
"I give the price a five out of ten."
"We don't have any issues with the price."
"The price of the solution is expensive."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"I'm a technical guy. But I know it's expensive compared to its competitors. After you have the on-premise solution, for your solution to be effective you have to subscribe to an "upper level," so there's another cost. There is also a subscription to cloud services, which is another cost."
"There is room for improvement with the pricing. It is an expensive solution. The issue with the pricing is more the way it is built. Right now we're paying per router, and there's a limitation there. I would like to see bundle-pricing where there is an overall solution cost."
"I believe that the price of Arbor DDoS falls under the bracket of medium to high price."
"Start with a small license. Measure your bandwidth requirements."
"It is an expensive product. I use this product for its different features."
"You need to find a way to get a good offering from Arbor by negotiating a price. That is the challenge."
"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."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
"Fastly is less expensive than one of its competitors."
"The pricing has been very competitive."
"In my opinion, Fastly is priced competitively."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"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."
