It's easy to set up because you point the DNS to it, and it's working in under 15 minutes
Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

Rapid attack detection and traffic visibility improve security management
The solution was intended for the big clients of Telefonica to clean their internet pipe. We deployed the service to clean the pipe. In some clients' data centers, we implemented a solution that detects and mitigates attacks using Arbor DDoS, our data center solution For me, the most valuable…

The product is highly stable and has valuable features, but it must provide more Layer 7 capabilities
We use the solution for DDoS protection in the routers The DDoS protection features are valuable. The product must provide more Layer 7 capabilities. It must provide deep inspection features. I have been using the solution for ten years. The tool has high stability. I rate the stability a nine…

Quotes from Members

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

Pros

"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"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 most valuable feature is its usability."
"The solution offers the flexibility to control configuration rules."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"It's very user-friendly."
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"We use it not only for DDoS detection and protection, but we also use it for traffic analysis and capacity planning as well. We've also been able to extend the use of it to other security measures within our company, the front-line defense, not only for DDoS, but for any kind of scanning malware that may be picked up. It's also used for outbound attacks, which has helped us mitigate those and lower our bandwidth costs..."
"I highly recommend Arbor DDoS to others."
"The artificial intelligence feature is most appreciated. This solution can lower the throughput and clear the traffic, which is something really important for us. It also provides good protection. It is user-friendly, and its integration has also been really fast. We have many critical applications, and it was easy to integrate Arbor DDoS with our website, mobile application, and web banking."
"It is fully mitigating the attacks. We've dealt with other ones where we didn't necessarily see that. The detection is very good. It's also very simple to use. Arbor is a single pane of glass, whereas with other solutions you might have a detection pane of glass and then have to go to a separate interface to deal with the mitigation. That single pane of glass makes it much simpler."
"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."
"The technical support of Arbor DDoS is good."
"It provides packet capture and we can block or whitelist whichever IPs we need to. Whatever traffic we want to block - and we get IPs from internal teams and from national teams - we block at the Arbor level only, because if it gets to the firewall then firewall bandwidth will be taken."
"Arbor DDoS is easy to use, provides effective blocking of DDoS attacks, and can be used for DNS, web, and main servers. Additionally, this solution is far easier to operate than others solutions, such as Fortinet DDoS."
"The most important aspect, in general, is that the price is suitable for most clients."
"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."
"This is a hybrid solution."
"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."
"The DDoS protection features are valuable."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
 

Cons

"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."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"They lack a good way to manage DNS as a company, since everything is relegated to single account logins until you get to the higher levels. They have come out with a paid feature to remedy this, but I have not had a chance to fully review it yet to know if it fixes the access problem."
"Integration involving API with other products could be more user-friendly."
"An integrated SSO feature would be useful for Cloudflare DNS."
"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"Cloudflare's console should be made more user-friendly."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"An issue which needs to be addressed concerns information I received of attacks on the radar and Arbor, allegedly, not taking any action."
"Arbor's SSL decryption is confusing and needs external cards to be installed in the devices. This is not the best solution from an architectural point of view for protecting HTTPS and every other protocol that is SSL encrypted."
"An improvement would be to provide information on how pricing is done on different customer levels."
"The solution's shortcomings are related to its documentation, so it's an area that needs to improve."
"With Arbor DDoS, its integration issues with other technologies or other vendors' technologies is an area of concern that could be improved."
"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."
"Sometimes it blocks legitimate traffic. If a legitimate user is trying to access the server continuously, the product suspects that this is a DoS traffic file. That is a case where it needs to improve. It needs machine-learning."
"The solution's IT support needs improvement."
"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."
"Lacks international presence."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"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."
"The product must provide more Layer 7 capabilities."
"It could use support in Spanish."
 

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The cost primarily depends on the size of the organization."
"We don't have any issues with the price."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"A free version of the solution is available."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"We are using the free version."
"Pricing is slightly on the higher side."
"Start with a small license. Measure your bandwidth requirements."
"The pricing of the solution is cheap."
"Arbor's products are very expensive. Their competitors are cheap when compared with Arbor."
"We do not use the Arbor Cloud DDoS solution because it is too costly."
"The solution's pricing is based on a licensing model that is expensive when compared to other tools."
"Arbor is striking a good balance between pricing and what they deliver."
"The price is a little high."
"The price of Corero is affordable."
"Its price is normal."
