Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

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…

Quotes from Members

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

Pros

"The most valuable feature is its usability."

"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 is very good at mitigating threats."

"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."

"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."

"Cloudflare has many features."

"The most valuable feature of Cloudflare DNS is security."

"What I like best about Cloudflare is that my company can use it to trace and manage applications and monitor traffic. The solution tells you if there's a spike in traffic. Cloudflare also sends you a link to check your equipment and deployment and track it through peering, so it's a valuable tool."

More Cloudflare pros

"The DDoS protection features are valuable."

"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."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"This is a hybrid solution."

"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."

"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 most important aspect, in general, is that the price is suitable for most clients."

"The product allows the users to adjust the thresholds."

"The equipment works very well, and I have not encountered any issues with it. It is a good solution for my company."

"The product's initial setup phase was really easy."

"The solution already has security profiles and it can protect from DDoS attacks and other kinds of attacks."

"We have researched them all, and it's a good solution all around."

"Among its key features: Detects and mitigates DDoS attacks at L3 to L7; negligible to zero false-positives; Generates and sends reports without the need for an expensive third-party solution."

"The equipment works very well, and I have not encountered any issues with it."

"The protection resources and the support are valuable features of the solution."

Cons

"The solution could be more user-friendly."

"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."

"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."

"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."

"Support response time could be improved."

"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"There should be a specific price list for enterprise-level customers."

More Cloudflare cons

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"It could use support in Spanish."

"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."

"Lacks international presence."

"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."

"The tool needs to focus more on the area of application traffic management, where it currently has some shortcomings."

"I find that there have been issues in the past year with the solution hanging. It freezes often."

"The product’s pricing needs improvement."

"The primary area for improvement is the on-premises capacity limit, currently fixed at 10 GB."

"The web interface could be much better."

"The main improvement would be to change the firewall model, however, currently, everything is fixed and working well."

"The only thing they need to do is to automate it. Today, you must create tools that do not require the use of an expert or anyone with special skills."

"The challenge lies within the customer environment, particularly in Brazil, where companies have stringent security requirements for implementing solutions."

Pricing and Cost Advice

"The product's pricing is minimal compared to other products."

"We are using the free tier of the solution."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"The price of the solution is expensive."

"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."

"The solution is expensive when compared to other products but offers unlimited bandwidth."

"We don't have any issues with the price."

"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."

More Cloudflare pricing and cost advice

"The price of Corero is affordable."

"The product’s pricing needs improvement."
