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.
Mitesh D Patel - PeerSpot reviewer
Effectively defends against threats like cross-site scripting (XSS), SQL injection, and others
It does bring value. For example, consider a BFSI customer. Their application is critical and represents their brand. Without a WAF, an attack could take their application down, harming their reputation. It leads to hampering the customer's workflow. With an Imperva WAF, they protect against attacks like DDoS or SQL injection, ensuring their application remains available and customers are happy. That's the main benefit for both the customer and the organization. The impact depends on the customer's use case. If their business primarily operates online, a CDN is beneficial for traffic optimization. Moreover, the integration options depend on the specific use case of our customers. Generally, integration capabilities are good with SIEM (Security Information and Event Management) parts.
Tanuj-Garg - PeerSpot reviewer
API discovery, bot defense, and DDoS capability optimize application security and development
I see areas in Radware Cloud WAF Service for improvement, specifically in its initial tuning period, because the machine learning model takes two to three weeks for baseline behavior establishment. Closely monitoring alerts during this period is essential to avoid false positives. There's an alert noise issue; during the early stages, we received a high volume of alerts for minor issues, requiring collaboration with the SOC team to fine-tune thresholds and concentrate on genuine threats. The documentation is not up to par, as while the platform's system is robust, the documentation, particularly for API integration, could be more developer-friendly with real-world use cases.

Quotes from Members

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

Pros

"Cloudflare has many features."
"It is a fast and secure DNS."
"It is easier to configure and develop documentation to see how we have configured firewalls."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"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."
"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."
"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."
"Easier http to https redirect using page rules"
"Very scalable and very stable firewall for web applications, with a good interface in its cloud version. Mitigation is its most valuable feature. The technical support for this product is also good."
"I have had a positive experience with Imperva Web Application Firewall's tech support so far. They are knowledgeable and respond on time."
"It is easy to use and has good security."
"It has threat intelligence and we are using Incapsula. With threat intelligence, we can separate HTTP and HTTPS traffic. We can use Incapsula to send all the threat intelligence to the WAF."
"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."
"It mitigates all of the availabilities of risks around web applications."
"If you are using the appliance as opposed to the virtual deployment, it can stand as the network layer-two and provide real transparency."
"It has fewer false positives"
"Radware Cloud WAF Service is user-friendly and easy to deploy."
"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 Cloud WAF Service offers better protection and can even provide significantly better security."
"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."
"Importantly, we have not experienced any zero-day attacks because Radware Cloud offers protection against emerging threats."
"Radware Cloud WAF Service has several valuable features, with good support and a user-friendly GUI."
"I highly recommend Radware Cloud WAF for its reliability and fast support."
"The most important aspect of Radware Cloud WAF is that it is over the cloud, offering a comprehensive solution that includes WAF, API protection, bots, and Layer 7 DDoS."
 

Cons

"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."
"The product needs to improve its automation."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"There might be helpful if there was some web application firewall feature."
"Integration involving API with other products could be more user-friendly."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"Imperva Web Application Firewall is very expensive."
"I think that better bot protection is needed in this solution."
"An improvement for Imperva WAF would be to reduce the number of false positives and create more strong use cases based on AI/ML or behavioral analytics."
"There could be some limitations that from the converged infrastructure perspective: when you want to converge with everything and you want Imperva to get there easily because it's not a cloud component. For example, when you want to build servers and you're using OneView to manage your software-defined networks, implementing Imperva right away is not that simple. But if you're doing just a simple cloud infrastructure with servers in there, you're good to go. Also, we are not able, with Imperva, to block by signatures. Imperva by itself needs to be complemented with another service to do URL filtering."
"The solution works for particular zones but isn't always the best solution for all zones."
"I loved the approach of the cloud. The cloud has a lot of new features, like advanced web protection and DDoS protection. If those could also be on-boarded onto the on-prem versions, that would be ideal. They need to pay attention to both deployment options and not just favor one."
"Imperva Web Application Firewall could improve the console by making it easier to use."
"It is complicated to integrate the solution's on-cloud version with other platforms."
"Radware Cloud WAF Service has limited integrations, and I would like to see it integrate with our use of Azure DevOps."
"We've had some issues with putting certificates in."
"Some of the tools are a bit difficult to navigate, and the user interface could be more user-friendly."
"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."
"Our only complaint is the reporting on the DDoS side. We also use Radware for on-premises DDoS protection and their Vision product. I just want to give paint you an example. We face so many Layer 3 and Layer 4 DDoS attacks on Cloud WAF. The reporting on those types of attacks can be improved."
"An area of improvement is the visibility at the attack level."
"If we want to publish services to a limited number of providers and we only want those providers to connect, we need to forward those requests to the Radware support team and they apply them, but it takes some time."
"The reporting features could be more intuitive with more real-time monitoring, which would help make faster decisions."
 

Pricing and Cost Advice

"There are no additional costs beyond the standard licensing fees."
"The product's pricing is cheap."
"We are using the free version."
"The tool is a premium product, so it is very expensive."
"The price of the solution is expensive."
"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."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The tool is expensive."
"The price of Imperva Web Application Firewalls is expensive compared to others."
"Licensing can range from one to twenty thousand dollars annually. Additionally, some features, including software support, require an annual subscription as well."
"It's an excellent product, but it can be very costly."
"It is very costly, but the return on investment is very high. Its cost was around $70,000, and we got it back in just six months."
"The cost of this solution depends on the platform."
"There are a couple of different licensing models."
"There is a license for this solution and we purchase the license annually with no additional fees."
"Radware Cloud WAF Service falls within a mid-range price bracket compared to other web application firewall solutions."
"We are paying $20,000 annually for six licenses that provide basic WAF functionality."
"I am not directly involved in pricing and setup cost discussions, but it seems that Radware offers a more cost-effective solution compared to F5. It is considered a good value for our budget."
"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."
"The pricing is fair."
"The pricing is fair; it's neither particularly cheap nor expensive."
"For the current market, the price for Radware Cloud WAF Service is exactly where we want it to be."
"The pricing is fair. We compared Radware to others using industry reviews and Radware is at the top right now."
