Has helped manage client domains with streamlined access control and threat visibility

I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service. It doesn't pay to try to host your own website.

Effective network and DDoS protection with suitable pricing

I use Corero for network DDoS protection projects. It is particularly effective in providing protection against network DDoS attacks I find Corero to be good, especially in a wide area. It does not have application filtering or application DDoS prevention, but for network DDoS projects, it is…

Solution ensures website availability and proactive threat mitigation

Over the seven years, the most valuable features of Imperva DDoS that I have found are related to DDoS attacks, which are a group of attacks, and not all of them can be resolved on the endpoint level before the website. Using the web firewall before the website is a common use case to protect against malicious requests to the website. I have utilized Imperva's Intelligent Traffic Filtering feature. This feature helps me understand how the attack is progressing and what is happening inside the requests to our website. It allows me to granularly grant or deny access to certain parts of our website. This helps when we know our customers and the types of requests that can be sent from them, enabling us to block some malicious requests. Imperva DDoS has User Behavior Analytics and Threat Intelligence on its board, and this helps us to be protected proactively. Imperva DDoS connects to its database of threats, storing whole information about attacks all over the world in one simple engine. Everyone can use this feature, which can connect to this engine and get information about what is going on at the world level. That is the way to be protected at the company's level. The integration capabilities of Imperva DDoS are very easy and simple. We can run it in 2 hours.

Quotes from Members

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

Pros

"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."

"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."

"Generally, I am satisfied with this product."

"The overall experience with Cloudflare is positive, with a rating of eight out of ten."

"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."

"Centralized, full-featured DNS."

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

"I rate its stability a ten out of ten."

More Cloudflare pros

"The DDoS protection features are valuable."

"SmartWall devices occupy only one-fourth of the width of a rack unit, making them very easy to install."

"The most important aspect, in general, is that the price is suitable for most clients."

"It is a good solution. Its vendor support is the most valuable. It is simple and works well if you have Juniper MX routers."

"It is an agnostic and transparent inline platform, which means that the maximum visibility of the symmetric and asymmetric traffic is available, even allowing bidirectional detection of the attack."

"The most valuable feature of Corero is its ability to handle smaller attacks in terms of the amount of volume and time. You can handle almost 100 perfect of the attacks locally."

"This is a hybrid solution."

"The solution can scale."

"The most valuable feature of Imperva, in addition to its strong knowledge base, is its effective protection for web applications."

"The features I have found most valuable with Imperva Web Application Firewall are account takeover protection, advanced bot protection, and API security."

"Technical support was very helpful."

"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."

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

"The most valuable features are DDoS protection."

"The dynamic profiling of websites is the solution's most valuable feature. The security is also good."

More Imperva Application Security Platform pros

Cons

"The solution could work at being less expensive. It costs a lot to use it."

"There should be a specific price list for enterprise-level customers."

"Cloudflare should add more documentation and pricing to the cloud version."

"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"Technical support is lacking."

"DNS Management."

"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."

More Cloudflare cons

"Lacks international presence."

"Juniper is known in our country, but it is not very popular. There is also not enough information about Corero. Our enterprise and financial sectors don't know about this solution. They need to provide more information and do more marketing for this solution in our country."

"It could use support in Spanish."

"The approach taken by Corero is to partner with other organizations in order to address volumetric attacks that cannot be handled by the hardware installed in the infrastructure. Corero does not have a solution for these attacks, so they are looking for partners to help them manage them. This approach is supplemented by local hardware, but the main focus is on the partnerships. It would be beneficial to have a more complete solution."

"The product must provide more Layer 7 capabilities."

"Corero needs to improve its application DDoS prevention capabilities and user behavior detection features."

"Imperva Web Application Firewall can improve by adding more features to the dashboard. increasing the visibility of the real-time events, besides configuring the administration itself."

"The tool needs to improve CPU and storage memory."

"It would be useful if the solution used more intelligence in attack protection. For example, firewalls are to be dependent on the configuration, but if they could have some data science around it the solution would be even better. The profiling of the traffic, and making decisions surrounding that should be intelligence-based, instead of being based on the configuration of the firewall itself."

"If they can bring in generative AI features, that would be useful."

"Sometimes our web application firewall will slow down."

"They recently separated the WAF and the DAM management gateways in order for each of these to be managed from different areas, so I believe it now requires additional investments for what was previously a single complete solution."

"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."

"The product's customization capabilities are a bit problematic, requiring support cases for backend modifications."

More Imperva Application Security Platform cons

Pricing and Cost Advice

"That is one of the great features. I was able to access the majority of the features and services for free."

"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."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

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

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

"The price of the solution is expensive."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

"We are using the free version."
