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

"From what I've seen so far, there are no negatives to report as of yet"
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"The most valuable features of the solution are performance and security."
"DDoS protection is this product’s most valuable feature."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"Cloudflare has positively impacted our organization by giving us flexibility to manage the DNS part, being quite fast, and allowing us to manage everything from a single dashboard, which is quite handy."
"I have not had a DDOS attack since, or at least not become unavailable due to DDOS which means my ROI is pretty good."
"The technical support on offer is excellent; they are very helpful and responsive, and we are quite happy with the level of service they provide to their customers."
"It is quite scalable, and we have not faced any issues with its scalability."
"The product is easy to use."
"The solution's ease of use is the most valuable feature."
"I am impressed with the product's multiple features like security."
"The product has a good mechanism to analyze trends and trigger events."
"It is integrated with AWS. So, it gives you a good first step."
"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 initial setup is straightforward."
"F5 Silverline Web Application Firewall works perfectly fine; it pretty much does everything that an Advanced WAF on-premises should do."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"The most valuable feature is flexibility."
"The stability of the solution is very good."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"I think F5 is one of the best web application firewalls in the world."
"Overall, this is a good security solution, but there is no such thing as a perfect appliance in IT."
 

Cons

"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."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Support response time could be improved."
"I rate technical support quite badly."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"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."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"We experienced some downtime in the fall of 2013, causing us to switch to Incapsula."
"We end up having to pay extra for features that AWS adds that we don't need."
"Perhaps the time required to detect anomalies can be reduced. Presently, it takes some time to determine whether a situation is normal or abnormal."
"The product is expensive."
"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."
"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."
"The product needs to improve its logs and reports to make it read better."
"The product could be improved on the global load and the integration with other solutions like Cisco and Dell EMC."
"We are doing a lot of automation, so I find the APIs are not very easy to use. So the current automation is not that good for F5 at the moment."
"One thing that was a hassle for us regarding F5 Silverline Managed Services was the deployment of this particular software."
"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. They should introduce more PoPs. The current number of PoPs that they have is around 10 or 12, which is still relatively less as compared to 2,400 plus PoPs that Akamai offers. The user latency or the number of hops a user needs before reaching the actual web application is less in Akamai because it has its internal fabric to route the traffic. They need to spin up more data to increase its traffic handling capability. They can also include the bot detection capability, though it is a pretty advanced functionality. If they could include DataDome like functionality, that is, bot prediction, then F5 Silverline Web Application Firewall will be top-notch in the market."
"You need to have Linux knowledge in order to use the shell."
"F5 Silverline Managed Services can improve by reducing the price."
"There is a lot of room for improvement with their tech support. I am not sure F5 Silverline Managed Services can be classified as having tech support."
"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."
 

Pricing and Cost Advice

"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."
"The product's pricing is minimal compared to other products."
"The price of the solution is expensive."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"The product's pricing is cheap."
"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 price is reasonable."
"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."
"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 product’s pricing is reasonable."
"The price of F5 Silverline Managed Services could be reduced."
"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."
"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."
