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

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

"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."

"CloudFlare has positively improved my site's speed, performance and security."

"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 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."

"It is easier to configure and develop documentation to see how we have configured firewalls."

"I like Cloudflare's application gateway and DDoS protection."

"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."

More Cloudflare pros

"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."

"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."

"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."

"I am impressed with the product's multiple features like security."

"If most of your internet presence from your application side is in AWS, AWS Shield is a great option."

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

More AWS Shield pros

"The initial setup is straightforward."

"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."

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

"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."

"F5 Silverline takes fewer resources to operate."

"F5 Silverline Managed Services has a very positive impact on my organization."

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

More F5 Silverline Managed Services pros

Cons

"There are some issues with the CDN services."

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."

"An integrated SSO feature would be useful for Cloudflare DNS."

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

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

"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."

More Cloudflare cons

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

"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."

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

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

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

"The time taken to detect anomalies must be reduced."

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

"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

"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."

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

"I think the management portal and the visual dashboard of F5 Silverline Managed Services could use an update."

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

"One thing that was a hassle for us regarding F5 Silverline Managed Services was the deployment of this particular software."

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

"The navigation is difficult to use."

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

More F5 Silverline Managed Services cons

Pricing and Cost Advice

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

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

"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."

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

"The solution is expensive when compared to other products but offers unlimited bandwidth."

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

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

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

More Cloudflare pricing and cost advice

"The tool's pricing is good."

"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 is cheap."

"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 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."
