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.

Lead Architect at a comms service provider with 1,001-5,000 employees

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 initial setup is extremely easy but will require access to your Domain Name Servers."

"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."

"The solution is very good at mitigating threats."

"Cloudflare improves performance on my websites and is a great partner for cloud infrastructure for anyone who wants to use the security service and other features."

"It's a great product because it's scalable, has great coverage, and is mature with good defenses against DDoS attacks."

"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."

"So far I use free tier and happy with it."

"The most valuable feature is its usability."

More Cloudflare pros

"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."

"It is quite scalable, and we have not faced any issues with its scalability."

"The product has a good mechanism to analyze trends and trigger events."

"We have integrated the tool with Active Directory. The most important feature is that it's transparent and doesn't degrade the performance of our solution. Additionally, it's easy to configure, which is crucial for us. It's easy to use and set up and stops attacks on our servers. We haven't encountered any attack problems because the solution stops them in real-time. AWS Shield specifically focuses on defending against denial-of-service attacks, making it a great solution for that type of threat."

"It is integrated with AWS. So, it gives you a good first step."

"The solution's ease of use is the most valuable feature."

"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 automatic detection and mitigation of DDoS attacks in the product operates in real-time and provides satisfactory results."

More AWS Shield pros

"Its flexibility is the most valuable because it is a managed service. The good part is that you don't need to set it up. It just needs DNS routing, which is the easiest thing. Our client had Akamai for certain websites because they were using CDN features. They had NetScaler on the internal zone, F5 AWAFs on the data centers, and no WAF at all in the cloud. One of the main activities of the project was to move all these policies into a single WAF so that we could control and use that as a choke point. That exercise itself was very easy because it was a managed service and F5 Silverline Web Application Firewall does that for you. That's the best thing about F5 Silverline Web Application Firewall. It is easy to apply policies on-premises. If you have AWAF on-premises and you want to replicate some policies on F5 Silverline Web Application Firewall, other than the policies that it applies by itself, it is easy because you have a team that supports it. F5 Silverline Web Application Firewall works perfectly fine. It pretty much does everything that an Advanced WAF on-premises should do."

"The stability of the solution is very good."

"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."

"The initial setup is straightforward."

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

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

"This is a good product that you can rely on."

"F5 Silverline offers load balancing, flexibility, and reliability."

More F5 Silverline Managed Services pros

Cons

"The documentation could improve for Cloudflare DNS."

"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."

"DNS Management."

"There might be helpful if there was some web application firewall feature."

"The product needs to improve its automation."

"The analytics, basically the dashboard, doesn't have much to it."

"We experienced some downtime in the fall of 2013, causing us to switch to Incapsula."

"There should at least be a read-only view of the data so that resellers can properly support the clients."

More Cloudflare cons

"The product is expensive."

"Perhaps the time required to detect anomalies can be reduced."

"AWS Shield has limited coverage as it only protects against common and high-volume network and transport layer attacks, such as SYN floods."

"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. It could be improved in terms of architecture requirements and then ongoing support requirements as a secondary component to it. People tend to set up things like this, and they just expect it to work without the care and feeding that needs to go back into it either from an application team or a network environment team."

"The product should give users more flexibility to customize their security policies according to their requirements."

"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."

"The network has been experiencing frustrating performance issues today, which is not typical for Nigeria."

"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."

More AWS Shield 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."

"I just hope the price can be cheaper."

"The price of F5 Silverline Managed Services could be better, they are not very flexible."

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

"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."

"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."

"You need to have Linux knowledge in order to use the shell."

"One negative aspect is that the product is expensive."

More F5 Silverline Managed Services cons

Pricing and Cost Advice

"The price is reasonable."

"The product's pricing is cheap."

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

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

"A free version of the solution is available."

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

"There are no additional costs beyond the standard licensing fees."

"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."

More Cloudflare pricing and cost advice

"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."

"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."

"We pay $3000 per month for the solution."

"The tool's pricing is good."

"The product’s pricing is reasonable."

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

"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."
