Advanced protection has secured critical web workloads and provides clear traffic visibility
From a security perspective, there remains a security loophole, as some browsers in the market can bypass the Turnstile solution, which requires approximately 40 seconds to do so. From a performance perspective, this is acceptable. We also tried Google reCAPTCHA, and that can also be bypassed. From a security perspective, I would say neither solution is completely secured. Regarding uptime, we have faced a couple of incidents due to Cloudflare in recent years, so I cannot say we receive 100% uptime for our region. We sometimes face challenges, including downtime and other issues. As a result, we are not receiving 100% uptime from Cloudflare's solution. Since most of our customers are in this region, we need alternatives. We need something more competitive than Cloudflare. Unfortunately, in Bangladesh, Cloudflare has three points of presence already, and we cannot find any other solution provider in Bangladesh as an alternative, which presents another challenge. Competitor solutions have more attack signatures, which ensure better security compared to Cloudflare's predefined configurations. Customers do not have options to modify any configuration parameters in Cloudflare, whereas other competitor solutions, such as F5 Distributed Cloud, allow customers to tune configurations according to their requirements. Cloudflare could improve in this area. Additionally, regarding visibility, Cloudflare has static visibility, but they could adopt dynamic graph features for their customers.

Protects critical infrastructure from alerts but GUI needs improvement
If we consider a default setup without customization, I would rate it a ten out of ten. However, the initial setup can be time-consuming for specific requirements needing customization, possibly requiring extensive fine-tuning. With the detailed and specific features we require, along with the need for tuning and customization, the process can indeed take several weeks. Allot DDoS Secure's case of integration with existing infrastructure is not too hard.

Cloud applications have gained stronger protection and real-time defense against web attacks
What really stands out for me in terms of advantages of F5 Silverline Managed Services is that in a single cloud platform, I can protect my web applications against attacks. I can also use my load balancer in F5 because they are providing and acting as a load balancer too, and they will support the volumetric and DDoS attacks and malicious attacks. Regarding the real-time threat intelligence feature, I do use this aspect in F5 Silverline Managed Services. It blocks malicious IPs or bad IPs for my server, protecting against my applications. For example, if someone is a bad actor trying to access via a malicious IP, I can block it because the threat intelligence has the capability to block the malicious IP. The adaptable and flexible security impacts threat response time positively. It is effective because it blocks my malicious traffic. Whenever I face issues related to that application, it automatically routes my traffic to act as a proxy and routes my traffic to their scrubbing center, especially in case of any volumetric attack.

Quotes from Members

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

Pros

"From what I've seen so far, there are no negatives to report as of yet"
"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 very clear and the information is very useful."
"DDoS protection is this product’s most valuable feature."
"The setup and configuration is also easy to perform and their support is excellent."
"This solution has improved the security of our organization."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The most valuable feature of Cloudflare DNS is security."
"The product has good architecture, concepts, and diagrams to protect end customers. Machine learning, artificial intelligence, and pattern creation are its most valuable features. The tool's alerting systems protect critical infrastructure."
"We have a lot of businesses that we put behind this solution, and it has really helped us in terms of monitoring the logs and incidents."
"F5 Silverline Managed Services is recognized as one of the best solutions in Gartner for WAF; I believe it can effectively manage vast amounts of traffic better than other brands like Citrix or FortiGate's WAF solution."
"Most vendors fulfill the requirements for standard DDoS protection, but F5 Silverline Managed Services has a better understanding of defending web applications like HTTP and can mitigate more bot activity than any other vendor."
"Most vendors fulfill the requirements for standard DDoS protection, but F5 Silverline Managed Services has a better understanding of defending web applications like HTTP and can mitigate more bot activity than any other vendor."
"Overall, this is a good security solution, but there is no such thing as a perfect appliance in IT."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"F5 Silverline takes fewer resources to operate."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
 

Cons

"The documentation could improve for Cloudflare DNS."
"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."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"Although I think it's quite good, it doesn't provide me with all the features I would expect to have if I were using Imperva."
"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."
"Sometimes their more advanced caching tools can cause higher first-byte times and problems with JavaScript."
"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."
"The tool's GUI and Java-based management platform needs improvement."
"There is room for improvement in the stability of the solution."
"The price is high in comparison to other products."
"The price of F5 Silverline Managed Services could be better, they are not very flexible."
"F5 Silverline Web Application Firewall, being a new product in the market or comparatively related to a new product, currently supports less number of PoPs."
"We'd like more AI to be used. Right now, they don't use it enough."
"Sometimes tech support can be slow. They take more time assigning engineers to complex issues, however, they resolve the issues by joining me to fix them."
"We need to have support for cloud protection, which is not offered by this solution."
"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
 

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 is expensive when compared to other products but offers unlimited bandwidth."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"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."
"The price is reasonable."
"The price of the solution is expensive."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"I give the price a five out of ten."
"I rate Allot DDoS Secure's pricing a five out of ten."
"The price of F5 Silverline Managed Services could be better, they are not very flexible. The price of the solution is based on the requirements of the enterprise."
"The price of F5 Silverline Managed Services could be reduced."
"The product’s pricing is reasonable."
"F5 Silverline Web Application Firewall works based on your bandwidth. They look at the clean bandwidth and do the pricing. 20% of a total pipe would be a clean bandwidth. The list price or a non-negotiated price for F5 Silverline Web Application Firewall would be around $2,200 per application per year for everything that you need. When you get into an enterprise kind of a setup, they negotiate this to the last bit. I would easily take 20% on that, which would be the cost, but it should cover all your Advance WAF features, bot protection, tech campaign, etc. It is built as a package and gives you most of the capability. You don't get the mobile SDK, which is an additional license. Mobile SDK is required only if you're buying or if you have a mobile application, and you are going to instrument F5 or Imperva into your mobile appliance. This anyways would be an additional module. It doesn't come within the WAF, but it is a WAF feature."
