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.

Easy event identification, highly stable, and customizable

Generally, F5 Advanced WAF initial setup is straightforward. However, our environment was more complex and it took us a little more time to customize the solution to where we needed it to be. Additionally, the customization didn't rectify everything. We had to do customization to a certain event to prevent attacks that it wasn't catching, but that might not necessarily be the solutions' fault. It could be more of our setup than the solution's fault and not being able to run the latest version or the newer version could be more of a limitation on our ability to put it in the right place. The whole implementation to have the solution run at the level we wanted it to take approximately five months. Our company's environment is one that we can't put a canned solution in front of. Our environment, cannot have a canned solution that might fit everybody else because of how customized this environment is. It does need a lot of tuning to meet our environment's requirements. I rate the initial setup of F5 Advanced WAF a three out of five.

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.

Quotes from Members

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

Pros

"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."

"Centralized, full-featured DNS."

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

"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. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"New and innovative way to protect the client's data."

"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."

"The most valuable feature is the web application firewall."

More Cloudflare pros

"The most valuable features of this solution are the WAF protection, Data Safe, and the seven-layer DDoS."

"The most valuable features of F5 Advanced WAF are the easy identification of events and customization. We can pinpoint our settings."

"It protects and mitigates damage in the network."

"The solution's most valuable features include application DDoS protection, bot blocking, and HTTP header verifications."

"The most valuable features of the F5 Advanced WAF are the enhanced ASM and the performance. Additionally, the usability and effectiveness are very good."

"F5 Advanced WAF secures our connectivity and combines both the main functions of WAF (balancing and web application security)."

"The best solution for WAF."

"F5 Advanced WAF has very good stability and scalability. Its initial setup was straightforward."

More F5 Advanced WAF pros

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

"They're quite easy to install and quite easy to set up. Clients really like that. Especially when you're dealing with the cloud, it's really easy."

"On the activity log, I can see the exact details, the visit, and the threat."

"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 is no need to have an appliance in house for the services because it is on the cloud."

"Real-time monitoring is also a great tool, as you may watch several parameters in real time."

"Imperva DDoS is fairly stable, and its availability is quite high."

More Imperva DDoS pros

Cons

"The product support needs to be accessible from more places, a wider area of coverage."

"The documentation could improve for Cloudflare DNS."

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

"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."

"Support response time could be improved."

"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."

"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 beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."

More Cloudflare cons

"F5 Advanced WAF could improve resource usage, it is CPU intensive. Additionally, adding automated remediation would be a benefit. For example, an easy button alerts us of the events that are occurring, and what we want to do at the time. An automated approach where somebody could be alerted very quickly. Instead of going and reconfiguring everything, an automated approach is what I'm looking at."

"One area for improvement in the product is its SSO integration, which posed challenges and required significant effort to resolve."

"F5 needs to improve API protection with a single F5 solution, without requiring additional modules."

"F5 Advanced WAF could improve the precision of the scanning. There are many false positives. They should improve their threat database."

"They could provide better pricing."

"The solution should include RASP for another level of protection at the code itself."

"There are opportunities for improvement in updating the user interface to a more modern look."

"F5 Advanced needs to improve its bot protection. The solution needs to have machine learning to learn the behavior of the customer to recognize the human versus the bot. This is a difficult feature to explain to our customers. I would like documentation about the bot feature to make it easier for the customer to understand."

More F5 Advanced WAF cons

"There’s nothing that’s missing in terms of features."

"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 should have more points of presence in Africa."

"Analytics in the area of risk need to be improved to supply more information to the users for creating better environments."

"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."

"It needs to be improved every time there are new attacks."

"We faced issues regarding compliance with client procedures. The client had strict compliance rules, and Imperva needed to be on a VM, while the client required containerization, causing a conflict. They went with Imperva for the on-premise version but shelved the cloud project due to too many blockers."

"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."

More Imperva DDoS cons

Pricing and Cost Advice

"A free version of the solution is available."

"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 give the price a five out of ten."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

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

"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."

"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."

More Cloudflare pricing and cost advice

"The pricing of F5 Advanced WAF is more expensive than other solutions like Radware and CD18, it is quite high."

"I would rate the pricing as seven out of ten"

"I am not sure about pricing but licenses are available on Google."

"The price of the solution is reasonable when compared with other products, such as FortiWeb. I am very satisfied with the price."

"The cost is slightly above average."

"I think the price is very high."

"There are different licenses available to use F5 Advanced WAF, such as BT, ASM, and LPM."

"F5 bundles up services and the bundle is what you pay for rather than individual components."

More F5 Advanced WAF pricing and cost advice

"It is expensive."

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

"Pricing could be more competitive."

"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."

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

"We are satisfied with the pricing."

"The license is on a yearly basis."

"We have an issue with Imperva Incapsula in the Iraqi market because of the high price."

Reviews from real users

“Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare

“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.”
