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.

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

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

"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."
"I like Cloudflare's application gateway and DDoS protection."
"Cloudflare is easier to manage than the solutions provided by these vendors, and the user experience is much more straightforward and appeals to a lot of developers."
"Cloudflare is very straightforward."
"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."
"If you don't want to spend too much time hosting your own DNS server or managing the domain, Cloudflare is a great way to rapidly get websites and services online."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"CloudFlare provides an answer to a variety of issues, so it gives you very high value for your money."
"The product is easy to use."
"The product has a good mechanism to analyze trends and trigger events."
"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."
"AWS Shield offers numerous protection features that are crucial at the application layer, safeguarding users from distributed denial of service attacks, man-in-the-middle assaults, and hacker orchestrations."
"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."
"If most of your internet presence from your application side is in AWS, AWS Shield is a great option."
"The solution's ease of use is the most valuable feature."
"The automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."
"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 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."
"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."
"The stability of the solution is very good."
"I think F5 is one of the best web application firewalls in the world."
"F5 Silverline takes fewer resources to operate."
"It's a good front end for public infrastructure"
 

Cons

"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"It would be helpful if the solution could continue evolving to compete with the other solutions on the market."
"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"There are some issues with the CDN services."
"Latencies are always a problem."
"The one feature that is paid is the custom nameservers instead of using the default ones, I want to use a custom one."
"We had to do a lot of digging and back-and-forth with technical support for specific use cases, and it might be helpful to have more screencasts or screenshots for common situations."
"The product needs to improve its logs and reports to make it read better."
"The time taken to detect anomalies must be reduced."
"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."
"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."
"Perhaps the time required to detect anomalies can be reduced."
"The product is expensive."
"The network has been experiencing frustrating performance issues today, which is not typical for Nigeria."
"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."
"There is room for improvement in the stability of the 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."
"The product could be improved on the global load and the integration with other solutions like Cisco and Dell EMC."
"I just hope the price can be cheaper."
"Regarding return on investment with F5 Silverline Managed Services, I would say only ten to fifteen percent, not more than that."
"We have complaints about the reliability of this solution."
"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."
"We need to have support for cloud protection, which is not offered by this solution."
 

Pricing and Cost Advice

"We are using the free version."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The tool is a premium product, so it is very expensive."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"We don't have any issues with the price."
"The tool is cheap."
"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."
"We pay $3000 per month for the solution."
"The tool's pricing is good."
"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."
"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."
"The product’s pricing is reasonable."
"The price of F5 Silverline Managed Services could be reduced."
