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.

Cloud security has improved remote access and has reduced costs for smaller client sites
I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

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

"CloudFlare's caching brings the load speed down from 4.32 seconds to 2.45 seconds."
"Cloudflare has many features."
"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."
"I rate its stability a ten out of ten."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The most valuable features of the solution are performance and security."
"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."
"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."
"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."
"Enables me to work from two locations."
"Cloudflare, in my opinion, was easy to implement."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare is by far the most effective solution that I have come across."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"Using Cloudflare One makes my work quite easy because for DDoS protection, all I need to do is understand the OSI model and click; it makes it easier than trying to write a command line or use a Linux command."
"The most valuable features are the configuration and configuring the process."
"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."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"F5 technical support is really good."
"F5 Silverline offers load balancing, flexibility, and reliability."
"F5 technical support is really good; it is better than A10."
"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."
"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."
 

Cons

"There are some issues with the CDN services."
"The pricing, setup cost, and licensing for Cloudflare are a bit on the higher side overall."
"DNS Management."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"The product support needs to be accessible from more places, a wider area of coverage."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed."
"The solution could use more analytics on the backend to give us more insights into everything."
"The solution could work at being less expensive. It costs a lot to use it."
"The initial onboarding was causing us some confusion."
"The initial onboarding was causing us some confusion."
"The pricing is an area that can be improved. Pricing, as far as I recall, was the source of our problems."
"Our subscription plan for the solution has a limitation of bot signatures."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"Cloudflare DDoS has poor technical support."
"Our customers no longer use Cloudflare because its service is subpar."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"We'd like more AI to be used. Right now, they don't use it enough."
"F5 Silverline Managed Services can improve by reducing the price."
"There is room for improvement in the stability of the solution."
"We need to have support for cloud protection, which is not offered by this solution."
"We are doing a lot of automation, so I find the APIs are not very easy to use. So the current automation is not that good for F5 at the moment."
"I just hope the price can be cheaper."
"The price is high in comparison to other products."
"We have complaints about the reliability of this solution."
 

Pricing and Cost Advice

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The price of the solution is expensive."
"The product's pricing is cheap."
"We are using the free tier of the solution."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The cost primarily depends on the size of the organization."
"There are no additional costs beyond the standard licensing fees."
"The prices are slightly expensive."
"The solution's pricing lacks transparency."
"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."
"The solution is not that expensive."
"Cloudflare Zero Trust Platform's pricing is good."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."
"The price of F5 Silverline Managed Services could be reduced."
"The product’s pricing is reasonable."
"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."
"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."
