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

"Cloudflare allows us to self-host services such as Rocket.Chat and Node-RED, in high-availability mode, thanks to round robin DNS which allows us to share one hostname between our two locations."
"If someone is looking for a secure and optimized wrapper over an open website, I would suggest CloudFlare services."
"The overall performance of this solution is what makes it one of the best solutions on the market."
"The technical support is good."
"New and innovative way to protect the client's data."
"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."
"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."
"The most valuable features of the solution are performance and security."
"The solution operates smoothly at its baseline level, and we do not encounter any issues at that level."
"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."
"I am impressed with the product's multiple features like security."
"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."
"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."
"It is integrated with AWS. So, it gives you a good first step."
"It is quite scalable, and we have not faced any issues with its scalability."
"My advice to others is this is a very reliable solution."
"If you are looking for web security and don't have any solution, just try it."
"Overall, this is a good security solution, but there is no such thing as a perfect appliance in IT."
"The initial setup is straightforward."
"It's a good front end for public infrastructure"
"The most important feature is that they have seven firewall protection, to protect our web servers."
"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."
"The best feature F5 Silverline Managed Services offers is 24/7 SOC co-management, which has drastically helped us during major DDoS attempts or web scraping incidents by handling the triage and mitigation entirely and reducing our MTTR from many hours to a couple of hours or minutes."
 

Cons

"I think the APIs are a little bit hard for us to work with. The APIs could be more open so that we could integrate better with our SolarWinds or our monitoring solution."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"At the end, it is worth than giving your house keys to the NSA."
"It looks like they don't support as many TLDs as other registrars, but since they are very new as a registrar, I expect this may improve soon."
"Flexible SSL is nothing more than an illusion of security that you're presenting to your visitors."
"We're facing challenges due to an upgrade in the machine learning model. The problem arises from some users abusing the APIs, resulting in an influx of suspicious traffic. Cloudflare's learning model mistakenly identifies this traffic as human. Consequently, it assigns it a higher trust score, akin to legitimate human traffic, causing complications in our architecture. Previously, such traffic would have been categorized as suspicious, enabling us to apply appropriate blocking rules. However, we encounter difficulties distinguishing between genuine and suspicious traffic with the new categorization. Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"The product needs to improve its logs and reports to make it read better."
"We end up having to pay extra for features that AWS adds that we don't need."
"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."
"The time taken to detect anomalies must be reduced."
"The product is expensive."
"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."
"AWS Shield Standard requires improvement, particularly regarding its dashboard since it currently provides limited coverage against comprehensive DDoS attacks."
"There is an area for improvement regarding health checks. AWS Shield does not come with its own health check functionality."
"The navigation is difficult to use."
"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."
"We have complaints about the reliability of this solution."
"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'd like more AI to be used. Right now, they don't use it enough."
"The product could be improved on the global load and the integration with other solutions like Cisco and Dell EMC."
"There is room for improvement in the stability of the solution."
 

Pricing and Cost Advice

"The product's pricing is minimal compared to other products."
"We are using the free tier of the solution."
"The product's pricing is cheap."
"That is one of the great features. I was able to access the majority of the features and services for free."
"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."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The tool is a premium product, so it is very expensive."
"We pay $3000 per month for the solution."
"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."
"The tool's pricing is good."
"The tool is cheap."
"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 price of F5 Silverline Managed Services could be reduced."
"The product’s pricing is reasonable."
