It's easy to set up because you point the DNS to it, and it's working in under 15 minutes

Cloudflare is highly scalable. Cloudflare is a system with a web portal that the end users like me see. It's a console where we can adjust the DNS, caching, and security features all in that console. Cloudflare owns thousands of servers across the world that cache the data. It's a powerful solution. When clients sign up for Cloudflare, they're getting this monster content delivery network, security, and a web application firewall in one. It's all rolled into one, and it's massive. Unless you have your website hosted on a massive hosting provider, there's no way that you can deliver the amount of data that Cloudflare can provide to the end users. If you have static content, there's no way that you can ever match what Cloudflare can do. Obviously, there are competitors to Cloudflare that do the same, but I'm saying other types of solutions. Let's say you go with F5. Great, that's on-prem. That's in your colo. You can't deliver as much data to the internet as you can with a CDN. You don't have to spend $20,000 on a net scaler, F5, or whatever Cisco's selling now. You don't have to buy that. You pay them $50 a month or $150 a month. It's totally worth it because even in five years, you'll never get the performance value, not just the actual ROI. You have to consider how much throughput you can get with Cloudflare.

I like the content monitoring feature which I haven't seen in other WAF solutions.

They could improve by minimizing false positive results. Although this occurs less with Imperva, we would like to see some further improvements. We have been using this product for last 1 years, it's result is very impressive. But due to the excessive load on the Web site where thousands of requests‎ are generated from legitimate users, however the request in which any sequential or specialised characters are requested would be directly blocked by impreva . Currently imperva blocks the special character request generated from the user, as I conduct a test where I am parsing the encoded html values of the same special characters to the input field, imperva bypasses these encoded values for example : ' i.e. %27 or / i.e %2F, the WAF bypasses these encoded characters. I hope that this device should have a capability to detect the pattern which is associated with Xss or Xsrf, rather then by not blocking the request which contains any special characters.

The interface is easy to use, and the solution protects us from OWASP Top Ten threats

DDoS protection was the critical feature we wanted when we decided to go with Radware. The company faced many DDoS attacks at the time, and we didn't have a solution. It's not the only reason we chose Cloud WAF. We do use it for other use cases. Cloud WAF's interface is easy to use and protects us from OWASP Top Ten threats. Our dev team do QA checks on applications before they go live, but Cloud WAF creates an additional security layer on our website. The solution protects against multiple threat types. We see SQL injection attacks and DDoS probes constantly. Attackers attempt multiple queries and enumeration attacks against our applications. We previously had a basic firewall with an IPS feature set, but it wasn't providing the same level of protection we get from the WAF. CloudWAF matches things automatically and identifies any threats. It seems to be doing its job. We sometimes have strange code-related behavior. When our developers write some poorly written code, it generates events in Cloud WAF. It's generally effective at detecting. We had an issue with a misconfigured rule where it blocked legitimate traffic. Overall, we haven't had many issues with it in the last three years. We leave it alone.

Quotes from Members

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

Pros

"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."

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

"The UI is good."

"From what I've seen so far, there are no negatives to report as of yet"

"It is easier to configure and develop documentation to see how we have configured firewalls."

"The solution is stable, and the DNS servers are simple to use."

"There are key things that are used for our enterprise customers, such as Lambda and DNS."

"Easier http to https redirect using page rules"

More Cloudflare pros

"We have peace of mind that nobody will use malware on us or try to hack our website."

"Scalability is pretty easy on the base platform. You just add another, and you're ready to go."

"The three-second service level agreement is already better than the competition."

"Integration with IBM AS/400 and Db2 is okay."

"The dashboard is good and user-friendly."

"The solution's most valuable aspect is that it is easy to configure."

"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."

"Technical support was very helpful."

More Imperva DDoS pros

"The most valuable feature of Radware Cloud WAF Service is the visibility into attacks that are being cut off instantly."

"What makes this a comprehensive offering from Radware is that it combines WAF, ADA, bot management, and API protection, which is not currently available from any other provider in the market."

"Radware Bot Manager has been very useful. If any user tries to save a password on a mobile or a browser, it blocks that. We can see all the details about the traffic and port requests."

"I particularly appreciate the low administrative burden of this solution, as well as the excellent monitoring tools."

"Integration is very easy."

"The isolation feature is the most important one because everything is going directly to Radware first and then it goes into our system. What we get is the filtered version of everything that would otherwise come directly to us."

"Cloud WAF's interface is easy to use and protects us from OWASP Top Ten threats. Our dev team do QA checks on applications before they go live, but Cloud WAF creates an additional security layer on our website."

"Radware Cloud WAF Service has several valuable features, with good support and a user-friendly GUI."

More Radware Cloud WAF Service pros

Cons

"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."

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."

"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."

"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."

"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."

"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."

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

"The solution could be more user-friendly."

More Cloudflare cons

"A limited tool if you're looking to customize."

"Pricing can be improved, as it is quite expensive."

"I would like to have support for SSL management and secure DNS."

"We would like them to hire people in Sweden because it's quite hard when people are sitting in the UK or Belgium because some of the customers really want them to be local."

"The rules surrounding the making of web applications could be improved."

"It would be better if we were able to manage and apply changes to multiple websites/web applications, and search WAF logs for multiple websites, via the Incapsula dashboard."

"The solution needs to improve Integration with third parties for their on-prem deployment models. The integration is not that good yet."

"The cost could be lower; our end clients need to have a high budget to purchase this solution."

More Imperva DDoS cons

"The connection between the front and back ends could be improved."

"The lower-level technical team at Radware could improve their approach to problem-solving as they sometimes are very slow."

"Radware's bot manager can be improved because it's very complicated to implement for apps. Radware could also add alerts by WhatsApp or Telegram. It only sends notifications via email or SMS."

"We receive many reports from our security team of IPs flagged by our security tools, such as Palo Alto. I cannot add the file containing the IPs to get them blocked; instead, I have to contact Radware support and open a ticket for them to do it. I need to be able to block flagged IPs myself, as it currently takes more time to open a ticket, contact the support team, and wait four to six hours for a response. I want to be able to upload a file with 2,000-3,000 IPs in the console and then apply and save the configuration."

"There is a lot more that is expected from Radware's automated analytics for looking at events. There needs to be more context of where protection is required these days."

"The Cloud Portal has room for improvement."

"The integration part could be better."

"Radware does not have much online training available to help customers get the most out of this solution."

More Radware Cloud WAF Service cons

Pricing and Cost Advice

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

"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."

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

"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."

"The price of the solution is expensive."

"There are no additional costs beyond the standard licensing fees."

More Cloudflare pricing and cost advice

"The cost is on par with other solutions such as Cloudflare and Akamai."

"It is expensive."

"It is a very expensive solution. The price is very high. A lot of customers tell us that they would love to use Imperva more. I have some customers who have 50 websites, but they have only 10 websites on Imperva because of the price. They would love to have all their websites running through Imperva, but they can't. They have to choose the more critical websites to protect because the price is very high. It is a very good product, but it is too expensive. If you buy a plan for 20 megabytes and you don't consume all of your 20 megabytes, it is okay, but if you consume more, you are charged for the superior traffic."

"There is a license or subscription renewal that our customers pay."

"It is not expensive compared to the other similar solutions in this category."

"Pricing could be more competitive."

"The license is on a yearly basis."

"For enterprise contracts you will be in touch with a dedicated account manager who will guide you regarding licensing."

More Imperva DDoS pricing and cost advice

"I believe the prices are fair."

"We are based in El Salvador and don't have a direct license with Radware; we purchase the license through resellers. The pricing is reasonable, as I managed an Akamai product in a previous position, and Cloud WAF is competitively priced."

"If you plan to deploy Cloud WAF, keep in mind that the product is priced based on the megabits of traffic that pass through and the number of transactions. You should get your requirements correct up front. The active attackers feed and CDN services cost extra, so you need to negotiate these features upfront."

"For the current market, the price for Radware Cloud WAF Service is exactly where we want it to be."

"The price is a bulk average."

"The pricing is fair. We compared Radware to others using industry reviews and Radware is at the top right now."

"We are paying $20,000 annually for six licenses that provide basic WAF functionality."

"The pricing is fair."

Overview

Cloudflare is a highly-regarded Content Delivery Network (CDN) and a Distributed Denial-of-Service (DDoS) protection solution. The robust global connectivity cloud platform that is Cloudflare ensures users are able to connect to the Internet quickly, securely, and reliably. Cloudflare is one of the world's largest networks in the marketplace today. Using Cloudflare, businesses, educational entities, NGOs, vloggers, bloggers, and anyone else with an internet presence can experience more secure, faster websites and applications.

Cloudflare has safe, secure data centers in close to 300 cities worldwide to ensure every
client request is filled as quickly as possible. It is Cloudflare’s edge network that makes this
possible by keeping content and other services as close to each client as possible, so the
information requests are always only seconds away.

Many organizations that work in democracy, civil society, human rights, or the arts are able to
access Cloudflare's highest levels of protection for free via Project Galileo. Additionally, official
election websites can be secured from hacking and fraud through Cloudflare’s Project
Athenian, also at no additional cost.

Cloudflare can also help organizations of all sizes develop a robust zero-trust strategy to
ensure the highest levels of productivity and profitability. Employees, stakeholders, and end users have a greater level of satisfaction and overall improved user experience, which can, in

Reviews from real users

“Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare
comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and
an SSL certificate automatically protects your website. If you have a connection between your
website and your host, the server, Cloudflare, and the host, you don't necessarily need a
certificate.” Spencer M., Owner at Tech Exchange

“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.” Daniel P., Network Engineer at Ufinet

“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.” PeerSpot user, Competence Center Manager at a tech services company

Reviews from Real Users

Below are some reviews and helpful feedback written by Imperva DDoS users.

PeerSpot user, Etienne W., CDN & Cybersecurity Engineer - Web performance & security at CDN Tech / Ecritel, says, “It is a good solution that allows us to protect websites. It is stable, scalable, quick and easy to use.” He goes on to explain, “WAF protection works almost out-of-the-box. The Anti-DDoS mitigation in less than 1s, I saw it many times in production, I can say it works. CDN has high performances, and the Smart Caching mode is really "smart" (you can do some efficient caching even if you're not a specialist). Its unique interface for managing security performance and ease of use are the most valuable features of this solution."

An IT Senior Manager at an outsourcing company mentions, “The most valuable features are DDoS protection. The Incapsula [Imperva DDoS] environment helps us monitor all the web activity. All the web activity is passed through their WAF cloud services, then that can help us to monitor those activities. That can help protect against DDoS hacking.”

Another PeerSpot reviewer, Ben D., Sales Executive at EVVO LABS, comments, "Imperva Incapsula [DDoS] has many valuable features. One, it protects the top 10 OWASP vulnerability, the open web application software platform, this is standard. Secondly, it protects against broken authentication. As well, it has remote execution of code."

A Solutions Architect at a financial services firm states, “The solution's most valuable aspect is that it is easy to configure. The solution keeps itself up to date itself and there's no customization that we need to do. It makes it extremely easy and cuts back on the amount of work required, and saves us on man-hours.”
