Owner at Tech Exchange

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.

A tool for centralized management including inventory and sales tracking

Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Quotes from Members

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

Pros

"The solution automatically detects and responds to certain types of traffic based on geolocation."

"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."

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

"The DDoS protection is the most valuable aspect of the solution."

"Centralized, full-featured DNS."

"It is a fast and secure DNS."

"Easier http to https redirect using page rules"

"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."

More Cloudflare pros

"The initial setup was was easy to install."

"The best solution for WAF."

"F5 helped to meet compliance and regulatory requirements."

"F5 Advanced WAF is a comprehensive community platform with a strong commitment, making it valuable for businesses."

"The most valuable feature of F5 Advanced WAF is its grand unity of the implementation, where you have the freedom to configure based on how it affects your use case or your organization. With the default setting of implicit deny, you can gradually start defining and deploying the tool to align with your environment, whether it is outdated, recent, or futuristic. This allows you to customize the solution to protect you from threat actors. You have the ability to define what the advanced threat act should do - whether it should alert, deny, or both - and it will deliver based on your configuration. Unlike other online solutions, F5 Advanced WAF provides flexibility to deliver to your unique environment the way you want."

"There are a lot of good features."

"The product has valuable features for load balancing, monitoring tools, and HPXpress services."

"Good technology for mitigating different application attacks, e.g. DDoS, DNS, and layer seven attacks."

More F5 Advanced WAF pros

"This solution allows the user to easily scale out application delivery, and provides secure remote access."

"We use the solution's IP Reputation and bot protection features."

"The flexibility in configuration options is impressive."

"The most impressive thing about Citrix ADM is that we don't encounter latency."

"It allows students to access required software for their studies."

"The GSLB feature allows us to move services between data centers. We can do this in either a planned or unplanned manner. We have experienced service provider outages at our primary data center and GSLB will kick in to automatically modify DNS records to point to a secondary data center (active/passive). We also make use of GeoIP information to point clients to the closest data center for accessing applications."

"SSL Offload"

"Most of the functions are user-friendly and great."

More NetScaler pros

Cons

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

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

"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."

"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."

"Support response time could be improved."

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

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

More Cloudflare cons

"They should work on the virtualization of NGINX."

"F5 Advanced WAF could improve the reporting. It's a bit difficult to populate, them. If you're not so familiar with the functions, such as where to find the logs and other settings."

"There is a gap in report management."

"More legacy protocols should be added to the solution."

"I would like to see a better interface and better documentation compatibility with other products. It's more complicated with OWASP."

"While F5 Advanced WAF does limit the number of partners in certain regions to ensure successful business transactions, they could also benefit from expanding their partnerships and making it easier for more people to learn about and become experts in F5 Advanced WAF. By doing so, they could increase the reach and exposure of their solution, similar to how Cisco has become widely recognized in the security industry."

"F5 Advanced WAF sells perpetual licenses as perpetual assets during sales without informing me that support ends after a few years."

"Nevertheless, F5 products are generally considered to be hard to deploy."

More F5 Advanced WAF cons

"Citrix ADC is a complex product, and it takes time to understand these things. But the documentation is poor, and the deployment is difficult. Integration could also be better because what I find is that you cannot easily integrate the panel in the second sector. What I have found is that in the last index, there is a limitation when getting validated. Technical support could also be better."

"An area for improvement would be the difficulty in finding information about standard licensing costs over the internet. They should provide some reference prices on the net to be quickly referred to."

"The solution could be more secure."

"Manageability and adaptability can also be challenging for end customers."

"The only thing customers told me that could be improved is that they would like to be able to purchase and receive the products in one box, rather than two boxes. This is something related to marketing, though."

"Citrix ADM needs to improve on its additional features and reduce the communication ports."

"I am not an expert in this solution, but simplicity and user-friendly interfaces are crucial for me. I would appreciate advice from Citrix, particularly in the form of an interactive guide for API protection. It would be helpful if they could provide specific points and recommendations for cybersecurity, indicating areas that need attention or improvement. I find such interactive guidance valuable."

"Currently, the support team's responsiveness is lacking, and the technical personnel on calls often seem unfamiliar with the issues or inadequately trained."

More NetScaler 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."

"A free version of the solution is available."

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"The price is reasonable."

"We are using the free version."

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

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

"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."

More Cloudflare pricing and cost advice

"Licensing fees for this solution are paid on a yearly basis."

"F5 Advanced WAF's pricing is high."

"F5 Advanced WAF is not a cost-effective solution. Although they are attempting to reduce prices with their VE and cloud options, they are more expensive than other solutions. The solution is more expensive on average."

"F5 Advanced WAF pricing structure should be adjusted to meet the need of small to medium-sized companies."

"The way we deployed it, I would rate it a four out of five in terms of pricing."

"Pricing for this solution is higher than average."

"It is expensive. Its price should be better. Its licensing is on a yearly basis. Its licensing is also based on the model. There are no additional costs."

"The pricing is too high."

More F5 Advanced WAF pricing and cost advice

"The licensing costs for this solution vary depending on which model is being used."

"We are quite happy with price. It's not too high."

"The tool is cheap."

"I do not have any experience with the pricing of the product."

"For the specific use case that my customers primarily engage with, I would give the pricing a rating of seven out of ten."

"Price-wise, I feel that the solution is a little bit expensive."

"The solution's pricing is very high compared to its competitors."

"The pricing could be lower."

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

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

“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
