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

"From a technical point of view, Cloudflare is the best CDN."

"The UI is good."

"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."

"Generally, I am satisfied with this product."

"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"

"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."

"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."

"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."

More Cloudflare pros

"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 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."

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

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

"The product is easy to use."

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

More AWS Shield pros

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

"The most important feature is that they have seven firewall protection, to protect our web servers."

"F5 Silverline Web Application Firewall works perfectly fine; it pretty much does everything that an Advanced WAF on-premises should do."

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

"I think F5 is one of the best web application firewalls in the world."

"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."

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

"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."

More F5 Silverline Managed Services pros

Cons

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."

"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."

"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States. That could be a labor intensive job. A solution could be to enable users to create a rule where traffic is only allowed within a certain country."

"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."

"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."

"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."

"The one feature that is paid is the custom nameservers instead of using the default ones, I want to use a custom one."

More Cloudflare cons

"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."

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

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

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

"The product is expensive."

"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."

More AWS Shield cons

"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."

"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."

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

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

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

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

"The product could be improved on the global load and the integration with other solutions like Cisco and Dell EMC."

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

More F5 Silverline Managed Services cons

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."

"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."

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

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

"The product's pricing is minimal compared to other products."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"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."

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."

"The tool's pricing is good."

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

"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 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."

"The product’s pricing is reasonable."
