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.

Has enabled multi-layered threat mitigation but still lacks deeper visibility for advanced application attacks

PranavTelang

Lead Architect at a comms service provider with 1,001-5,000 employees

AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods. It does not provide inherent protection against more sophisticated layer 7 attacks such as HTTP floods. In such cases, integration with WAF is necessary, which results in additional costs for customers. To protect layer 7, layer 4, and layer 3, customers must implement both solutions. The service also has difficulties with static detection thresholds, which may not be sensitive enough to detect smaller application-specific attacks. While AWS Shield is a key security service, AWS should enhance their expert support with 24/7 response for complex attacks, which is currently limited.

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

"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."

"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."

"The most valuable feature is its usability."

"It's very user-friendly."

"The solution is very good at mitigating threats."

"Generally, I am satisfied with this product."

"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"

"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."

More Cloudflare pros

"I recommend AWS Shield because it has proven helpful in tracking DDoS attacks within both my past and present environments, and without AWS Shield, a business could face potential losses, as this tool helps in identifying and mitigating fake traffic that disrupts applications, ultimately supporting business continuity."

"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."

"I am impressed with the product's multiple features like security."

"It is integrated with AWS. So, it gives you a good first step."

"It is quite scalable, and we have not faced any issues with its scalability."

"The product is easy to use."

"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."

"AWS Shield is aligned with the web application firewall (WAF), and they work seamlessly together, primarily working with Elastic Load Balancer, CloudFront, and Route 53 for CDN and DNS services protection."

More AWS Shield pros

"This product is a reliable defense from malicious attacks on a network environment."

"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."

"The solution is very good at intercepting traffic before it gets to our data centers."

"The most valuable features of the Imperva Web Application Firewall are performance and flexibility. We can extend or customize the box itself."

"DDoS protection and WAF are the most valuable features. It is easy to deploy a service. It is easy and quick to deploy to a new website."

"The most valuable features of the Imperva Web Application Firewall are DDoS, malware, and the other malicious threat prevention it provides. Additionally, third-party integration is available. You can forward the log for further analysis."

"Incapsula takes care of the CDN infrastructure and bandwidth volume, providing several enterprise "load balancing" features."

"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."

Cons

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

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

"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."

"The integration of LLMs on the dashboard is something that is needed in the tool."

"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."

"There are some issues with the CDN services."

"There might be helpful if there was some web application firewall feature."

More Cloudflare cons

"The management of it is a bit hard. If you don't engineer it on the front side, it is hard to go back in and change it. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."

"The product should give users more flexibility to customize their security policies according to their requirements."

"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."

"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."

"Perhaps the time required to detect anomalies can be reduced."

"The product needs to improve its logs and reports to make it read better."

"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."

"The time taken to detect anomalies must be reduced."

More AWS Shield cons

"Imperva Web Application Firewall could improve the API integration. It was complex for us. Additionally, The onboarding could be better."

"The only disadvantage of Imperva is that it is a pretty costly solution."

"I would like the solution to improve its support response time."

"Imperva should have more points of presence in Africa."

"It's a complicated tool to keep."

"Imperva DDoS does not provide version control."

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

"I'd like the option to pick your bot protection."

Pricing and Cost Advice

"The product's pricing is cheap."

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

"The price of the solution is expensive."

"We don't have any issues with the price."

"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 cost primarily depends on the size of the organization."

"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."

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

More Cloudflare pricing and cost advice

"The tool is cheap."

"It depends on your subscription level and the volume that you're spending with AWS. So, it is very relative to the consumption alignment in your subscription level. It is a well-constructed, scalable pricing option, but it is relative to how much you're spending on AWS. Because the more you spend, typically, the more you get off on services like this. I find it to be comparable to other solutions."

"We pay $3000 per month for the solution."

"The tool's pricing is good."

"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."

"Although the pricing can be a little high, it is worth the protection and security that it offers."

"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."

"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 solution's pricing is an issue."

"The tool is expensive."

"Everybody complains about the price of this solution."
