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

"Even when there is a high load on our servers, Cloudflare is able to cache the data and serve it to users, ensuring they can still access the website."

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."

"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."

"The most valuable feature is its usability."

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

"Generally, I am satisfied with this product."

"DDoS attacks target unprotected machines. Cloudflare detects and stops these attacks using internal systems. It identifies incoming DDoS attacks, issuing challenges or blocking them immediately."

"Cloudflare makes it easier for me to handle and set up DNS for multiple users and multiple clients, and basically go in and access their account, make the changes they need, and it's a one-stop shop."

More Cloudflare pros

"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."

"AWS Shield is aligned with the web application firewall (WAF), and they work seamlessly together, primarily working with Elastic Load Balancer, CloudFront, and Route 53 for CDN and DNS services protection."

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

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

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

"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 product is easy to use."

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

More AWS Shield pros

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

"The stability of the solution is very good."

"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 is flexibility."

"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."

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

"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."

"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."

More F5 Silverline Managed Services pros

Cons

"It should be easier to collect the logs with companies like Sumo. However, based on my discussions with the salespeople, I understand that's how they make their money. With the enterprise product, they want people doing those kinds of enterprise features to do the logging. They want them to pay a lot of money, and that's where I have an issue with them. That should be a default. You should be able to get the log no matter what. The logging should be universal."

"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."

"The pricing could be improved."

"Cloudflare's free plan is limited to 5,000 records for their free plan. They should increase that. For example, if I create a domain called abc.com and a subdomain called a.abc.com, my record count will be two. I can make a maximum of 5,000 subdomains. However, if we use our own DNS hosted on another provider, there is no limit. Their free plan also lacks name server customization."

"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."

"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."

"There are some issues with the CDN services."

"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."

More Cloudflare cons

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

"The product is expensive."

"The product needs to improve its logs and reports to make it read better."

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

"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 time taken to detect anomalies must be reduced."

"We end up having to pay extra for features that AWS adds that we don't need."

More AWS Shield cons

"Automating processes could enhance F5 Silverline Managed Services."

"The price is high in comparison to other products."

"F5 Silverline Managed Services can improve by reducing the price."

"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."

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

"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."

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

More F5 Silverline Managed Services cons

Pricing and Cost Advice

"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."

"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."

"We are using the free version."

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

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

"I give the price a five out of ten."

"The price is reasonable."

"The price of the solution is expensive."

More Cloudflare pricing and cost advice

"The cost depends on traffic each month, so on average, it costs us between US$200 and US$300 per month."

"The tool's pricing is good."

"The tool is cheap."

"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 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 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."
