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.
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.
David Shlingbaum - PeerSpot reviewer
Simple solution and good WAF
Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section. Users get errors or EBAs, and if they want to read about it, they need to find it in the help section of the site. It would be more helpful to allow users to see more information and tips immediately from within the alert.

Quotes from Members

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

Pros

"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"It's very user-friendly."
"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."
"New and innovative way to protect the client's data."
"The most valuable feature of Cloudflare DNS is security."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"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 most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"The most valuable feature of F5 BIG-IP AFM is all of my workers enjoy using it."
"I find the signature base is very helpful to see traffic"
"It blocks various attacks and mitigates disasters from occurring."
"The setup and functionality are fairly straightforward."
"We use three main features. The first one is access control. The second feature we use is called IP intelligence. Finally, we have a DDoS safety feature."
"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 provides behavioral analysis via AI to detect malicious traffic."
"It excels in preventing downtime and maintaining application performance, which is crucial for our clients' security and operational continuity."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"The initial setup was straightforward. Straight forward because the plugin can simply be installed and then it does its job. It's not complex, there is no learning curve. The online scan is simple, you put in the website address and the scan gives us a report on the browser itself. It's simple to use."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"The initial setup was very easy."
"Domain name scanning since it allows us to scan all our domain names and determine whether it has malware or if is reported as phishing."
"The most valuable part is the analytics and visualization."
 

Cons

"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"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."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"Cloudflare should add more documentation and pricing to the cloud version."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"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 could be improved by introducing a mid-tier pricing option."
"Support response time could be improved."
"NGINX, which F5 purchased, has room for improvement in its features, particularly its load balancing or application load balancing features."
"The appliance and features could be enhanced further, especially in terms of security. Some features like the WAF firewall may seem expensive compared to the standard license, so there could be room for adjusting the pricing."
"There is room for improvement in Advanced Firewall Manager's dashboard statistics, especially during attacks."
"For configuring the firewall, every single vendor on the planet has pretty much the same logic when it comes to firewalls, and F5 has a completely different approach and completely different behavior."
"There should be simplified and better integration with BIG-IQ."
"Currently, we have eighty F5s and we need some kind of management software. It would be very helpful."
"The solution's UI could be improved."
"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."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"In terms of improvement, the cost factor is always there."
"Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section."
"The main improvement I would like to see is support for .NET applications. If they could include this feature, I would include more sites in the protection."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"I would rate this solution an eight out of ten. The reason is that we have found sometimes customers or Google saying that there is something wrong with the website but Sucuri says that the site is clean so we do have to look at the site manually which means that the Sucuri scan does not pick up anything and everything."
 

Pricing and Cost Advice

"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."
"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."
"We are using the free version."
"We are using the free tier of the solution."
"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."
"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."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The price of F5 BIG-IP AFM is a little more expensive than other firewalls on the market."
"As per pricing, I would not say cheap, but little higher than cheap, but not very expensive. So you can say kind of value for money solutions."
"F5 BIG-IP AFM is an affordable solution. There were not any additional fees other than the standard licensing."
"We have purchased a five-year licensing package for the product."
"We need to pay a yearly licensing fee for the solution."
"F5 BIG-IP Advanced Firewall Manager is not an expensive solution."
"The solution is slightly on the higher priced side."
"It's very expensive, and you pay extra for the models."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
"The ROI has been very good. Because of the solution, I have a tax break. The site developers were not always experienced people. We used to pay more for cleaning up the site when it was infected. Now, we have peace of mind knowing that the solution will clean up the site and that we won't have to go through the unnecessary process of restoring it from a backup. The protection on the WAF and the measures for backups have also prevented our site from going down."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
"I’d simply say it’s really worth it."
