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.

Provide DDoS protection and better security at effective rate
It is expanding its number of data centers for scrubbing traffic. Currently, there is only one POP for cleaning in South Africa. They might add another POP in North Africa, possibly in Nigeria or Egypt. Latency concerns customers, especially in regions like East and West Africa, where traffic has to travel to South Africa before returning. Increasing the number of POPs across the continent would help address these latency issues and improve overall service. While the platform is already quite strong, there’s always room for improvement, especially in keeping up with emerging trends and new types of attacks. Enhancing security capabilities could be beneficial. Integrating more advanced AI features could significantly improve its effectiveness and help customers leverage these tools more effectively. It would be great to see more focus on AI integration to handle and analyze data more efficiently.

Offers Application Protection Against Web Attacks
There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

Quotes from Members

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

Pros

"It is a fast and secure DNS."
"Cloudflare is a security SaaS provider that provides security and protects us from any application layer attack."
"The most valuable feature is its usability."
"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."
"I rate its stability a ten out of ten."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"On the site security, I can see which countries have incidents, whether it was a robot attack, a real human user, or non-human user."
"I like the user-friendly interface."
"Scalability is pretty easy on the base platform. You just add another, and you're ready to go."
"It is an effective threat mitigation tool."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"There is no need to have an appliance in house for the services because it is on the cloud."
"Gives us the ability to trace each connection, and to have logs to be able to differentiate between a positive and a false-positive intruder action."
"The solution is very good at intercepting traffic before it gets to our data centers."
"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."
 

Cons

"There should be a specific price list for enterprise-level customers."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."
"Latencies are always a problem."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"The weakest point of Imperva is their first level of support, which should be improved. They should also improve the access and security logs viewing directly on the portal. I would like to see better access and security logs through the portal and not only through a SIM solution. Currently, if you want to explore your access and security logs from Imperva, you need a SIM tool or a SIM infrastructure on your side to do it. You can't do it manually or directly through the portal, which is a big problem for us. I had a call yesterday with Imperva for the roadmap, and I just told them this. They agreed that this is an improvement point from their side."
"Imperva always needs to adjust to new versions of cyber attacks, it needs to be faster, improve the resiliency of the software of the solution."
"Imperva now offers add-ons to add functionality, but I would like to see these included in the product, even if it would cost more."
"The cost could be lower; our end clients need to have a high budget to purchase this solution."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"The product could use a broader scope in the area of policies."
"We had an issue when securing the web applications for DDoS protection."
"Incapsula services also provides load balancing services for their service IP address environment. So far, with monitoring their services, the IP address was only changed once."
"There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly."
 

Pricing and Cost Advice

"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."
"The product's pricing is cheap."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The cost primarily depends on the size of the organization."
"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."
"I give the price a five out of ten."
"Varies depending on the needs of the customer."
"The cost is on par with other solutions such as Cloudflare and Akamai."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"The license is on a yearly basis."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
"It is not expensive compared to the other similar solutions in this category."
"There is a license or subscription renewal that our customers pay."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a five out of ten."
