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.
Björn Lindman - PeerSpot reviewer
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…
Pawel Augustyn - PeerSpot reviewer
Provides outstanding resource management and application security across multiple geographies
The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications. The solution also monitors and blocks unconventional requests and maintains security efficiently. The scalability feature also allows me to manage and allocate resources dynamically without disrupting production traffic.

Quotes from Members

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

Pros

"New and innovative way to protect the client's data."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"From what I've seen so far, there are no negatives to report as of yet"
"Easier http to https redirect using page rules"
"The solution is stable, and the DNS servers are simple to use."
"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."
"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."
"The DDoS protection features are valuable."
"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."
"This is a hybrid solution."
"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."
"The most important aspect, in general, is that the price is suitable for most clients."
"I find the signature base is very helpful to see traffic"
"The solution is very straightforward. The usability is great."
"The decryption is great."
"The most valuable feature of F5 BIG-IP AFM is the iRules where I can customize the configuration."
"The most valuable features of F5 BIG-IP Advanced Firewall Manager (AFM) are the web gateway, load balancing, services, and applications available."
"The most valuable feature of this solution is that the blocking of IP's."
"It is stable."
"The product’s most valuable features are LTM and WAF."
 

Cons

"The solution could be more user-friendly."
"Integration involving API with other products could be more user-friendly."
"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."
"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."
"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."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"The product needs to improve its automation."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"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."
"It could use support in Spanish."
"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."
"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."
"Currently, we have eighty F5s and we need some kind of management software. It would be very helpful."
"Firstly, geolocation currently relies on manual updates. It has to move to automatic updates. There are no automatic updates for this feature. If some IPs, countries, or service providers move to another country, now you will be allow IPs that you previously denied. This is because you depend on the database, which doesn't update automatically. This is really a very important area that they need to improve."
"F5 could provide a distributed cloud version."
"F5 should increase its capability to prevent zero-day attacks. Having advanced technology similar to other vendors like Palo Alto for zero-day attack prevention would be valuable."
"The solution’s initial setup is not easy."
"The solution doesn't really meet our requirements for an edge firewall."
"There is room for improvement in Advanced Firewall Manager's dashboard statistics, especially during attacks."
"This would be absolutely the best network security solution if the price were not so high."
 

Pricing and Cost Advice

"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."
