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

"New and innovative way to protect the client's data."

"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."

"The tool is user-friendly."

"Smaller businesses have seen great ROI due to the low investment and strong performance."

"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."

"Easier http to https redirect using page rules"

"The API gives us the ability to remote control our DNS settings."

"Because our website is blazing fast it improves our conversion rates."

More Cloudflare pros

"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."

"Enables me to work from two locations."

"We mostly use Cloudflare WAF, and gets basic Cloudflaire DDoS, caching as extra bonus . We like the factor these features are all integrated into 1 console, simple to manage."

"The solution has different options that can be used to differentiate DDoS attacks."

"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."

"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."

"It will take the blow rather than our applications should an attack occur."

More Cloudflare One pros

"The 30% efficiency improvement has definitely resulted in increased revenue for us, and with our website performing much better, I am able to achieve faster cycle times in terms of lead to conversion."

"If you are looking for web security and don't have any solution, just try it."

"The initial setup is straightforward."

"The most valuable features are the configuration and configuring the process."

"My advice to others is this is a very reliable solution."

"F5 technical support is really good; it is better than A10."

"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 Web Application Firewall works perfectly fine; it pretty much does everything that an Advanced WAF on-premises should do."

More F5 Silverline Managed Services pros

Cons

"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."

"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."

"Access to the solution's dashboards is not intended for a service company. You are practically blind, and to validate a problem, you must view the customer's screen."

"Cloudflare could be improved by introducing a mid-tier pricing option."

"In the last two years, there has been a certain amount of downtime when using the VDM."

"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."

"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."

More Cloudflare cons

"The onboarding process can be improved a little bit."

"Our customers no longer use Cloudflare because its service is subpar."

"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."

"Our subscription plan for the solution has a limitation of bot signatures."

"Cloudflare DDoS has poor technical support."

"Feedback could be enhanced."

"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."

"The response time for support must be reduced."

More Cloudflare One cons

"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."

"The product could be improved on the global load and the integration with the other solution like Cisco and Dell. As a representor of the operation, we prefer to have one platform which can accommodate all type of integration. We are also looking for more improvements in the security policy configuration."

"There is room for improvement in the stability of the solution."

"Regarding return on investment with F5 Silverline Managed Services, I would say only ten to fifteen percent, not more than that."

"To make this solution much better, they must have a user-friendly configuration interface."

"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. They should introduce more PoPs. The current number of PoPs that they have is around 10 or 12, which is still relatively less as compared to 2,400 plus PoPs that Akamai offers. The user latency or the number of hops a user needs before reaching the actual web application is less in Akamai because it has its internal fabric to route the traffic. They need to spin up more data to increase its traffic handling capability. They can also include the bot detection capability, though it is a pretty advanced functionality. If they could include DataDome like functionality, that is, bot prediction, then F5 Silverline Web Application Firewall will be top-notch in the market."

"In terms of the scalability, this part is always so confusing because they are checking for packet count. Also, after an attack, they said that the throughput must be from gigabits but then I check my bandwidth and it is already done in gigabits. So it is a little bit confusing."

"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."

More F5 Silverline Managed Services cons

Pricing and Cost Advice

"The tool is a premium product, so it is very expensive."

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

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

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

"We are using the free tier of the solution."

"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 price of the solution is expensive."

"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

"Cloudflare Zero Trust Platform's pricing is good."

"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's pricing lacks transparency."

"The solution is not that expensive."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"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 tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The prices are slightly expensive."

"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."

"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 product’s pricing is reasonable."

"The price of F5 Silverline Managed Services could be reduced."
