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.
Nick Wilsdon - PeerSpot reviewer
An easily scalable and stable product that provides exceptional support
The product should provide improved bot detection and management. The product should also provide support for code management. Everybody working in CDN is currently looking for ways to better manage code deployment with various authorization levels and synchronization with our lower environments. Matching up what's happening in CDN with what's happening on the origin regarding testing would always be useful.

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.

Quotes from Members

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

Pros

"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The UI is good."
"The solution provides good load balancing and protection against DDoS attacks."
"It's very user-friendly."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"The technical support is good."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The solution is stable, and the DNS servers are simple to use."
"Rate limiting is a good feature that protects from volumetric attacks."
"Compute@Edge features are valuable to me."
"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."
"The product's initial setup phase is straightforward."
"Its initial setup process is straightforward."
"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."
"The product helps our organization to access sites located in different regions quickly."
"The solution has a very good interface."
"Setup was straightforward, very simple. I only entered the domain and Incapsula returned the DNS data that I needed to change for the protection to be configured."
"There are quite a few useful Imperva Incapsula features. For example, one of them is the reports. The graphics are very good and it's easy to configure. The whole process is very fast and reliable too. They have good tech support as well."
"The dashboard is good and user-friendly."
"​Technical support provides good, quick responses."
"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."
"Imperva DDoS helps us automate production. The client had specific requirements for a cloud project in the financial sector."
"We use Imperva DDoS to stop DDoS attacks and reduce the amount of unwanted queries against web services or web scraping."
 

Cons

"The integration of LLMs on the dashboard is something that is needed in the tool."
"Latencies are always a problem."
"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."
"Technical support is lacking."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"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."
"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."
"There are some issues with the CDN services."
"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."
"The solution's pricing could be better."
"Support is not that great."
"What I don't like about Fastly is that they charge a heavy price."
"The product should provide improved bot detection and management."
"Fastly's customer service area needs improvement."
"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."
"Imperva should have more points of presence in Africa."
"I would like to have support for SSL management and secure DNS."
"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."
"The salespeople tend to exaggerate its capabilities, which can cost you money if you don't verify the information."
"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 log analytics interface within Incapsula isn't really good. For example, if you have to get all logs from there, it's a very cumbersome process."
"Imperva DDoS does not provide version control."
"Some maintenance must be performed by our IT team."
 

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."
"The price of the solution is expensive."
"The price is reasonable."
"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 tool is a premium product, so it is very expensive."
"I give the price a five out of ten."
"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."
"The product's pricing is cheap."
"Fastly is less expensive than one of its competitors."
"The solution is cheaper than other products in the market."
"In my opinion, Fastly is priced competitively."
"The pricing has been very competitive."
"You need to pay a premium price for the tool."
"It is an expensive solution."
"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
"Pricing could be more competitive."
"The license is on a yearly basis."
"Imperva charges us based on bandwidth, which is better than other vendors that charge us according to data transfer."
"It is not expensive compared to the other similar solutions in this category."
"Varies depending on the needs of the customer."
"The data packages are higher than our needs so we end up paying for data that we don't use."
"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."
"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."
