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.

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.

Has faced challenges with bot detection while benefiting from strong threat monitoring and compliance support
Akamai's most valuable features include being industry recognized and PCI compliant, which is really great; their cloud is PCI compliant, and having a vendor that is PCI certified is crucial for organizations focused on PCI compliance. We utilize the real-time monitoring of the solution. Real-time monitoring helps us identify network vulnerabilities by allowing us to see a spike in traffic and understand the traffic levels compared to this time last month or last week. If we notice a sudden increase, we investigate further to determine if it indicates a DDoS attack or a card testing situation. In terms of threat detection capabilities, they are very good because Akamai has a SOC service that we have tapped into for active threat detection and threat hunting, and they monitor everything carefully 24/7. Scrubbing is done by Akamai as a backend service, and we utilize their SOC, which is a service that you pay additional fees for, allowing us to have our queries prioritized. Prolexic features help maintain business continuity during high-volume attacks by having built-in threat detection capabilities in its bot detection and other functionalities, as attacks usually occur through intelligent bots trying to infiltrate the system.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"Using the CDN of Cloudflare improved the speed significantly, reducing the page loading times to appropriate levels."
"The most valuable feature is the web application firewall."
"The most valuable features of the solution are performance and security."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"The aggressive caching and DDOS mitigation are the most valuable features offered by Cloudflare."
"There is no service as mature as Cloudflare that is also as easy to use, reliable, and hosted from excellent infrastructure."
"Cloudflare is very straightforward."
"The most valuable features are the configuration and configuring the process."
"The most important feature is that they have seven firewall protection, to protect our web servers."
"This is a good product that you can rely on."
"The stability of the solution is very good."
"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."
"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."
"F5 technical support is really good; it is better than A10."
"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."
"The solution does not have hardware or maintenance requirements and is very easy to scale."
"Prolexic technical support is second to none."
"The support from Akamai is great, and they provide excellent information and mitigation services."
"Akamai's most valuable features include being industry recognized and PCI compliant, which is really great; their cloud is PCI compliant, and having a vendor that is PCI certified is crucial for organizations focused on PCI compliance."
"They've scrubbed DDoS traffic that was blasting us offline, thus allowing legitimate traffic through and letting our service return online."
"The solution does not have hardware or maintenance requirements and is very easy to scale."
 

Cons

"If they improve on the placement of their data centers, it would be better."
"We had to do a lot of digging and back-and-forth with technical support for specific use cases, and it might be helpful to have more screencasts or screenshots for common situations."
"Honestly the product has not really improved the way of my organisation."
"Cloudflare could offer a better view or maybe dashboards of the main resources used in the client."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed."
"The solution could work at being less expensive. It costs a lot to use it."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."
"We'd like more AI to be used. Right now, they don't use it enough."
"You need to have Linux knowledge in order to use the shell."
"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."
"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."
"The product could be improved on the global load and the integration with other solutions like Cisco and Dell EMC."
"There is a lot of room for improvement with their tech support."
"It's expensive, though."
"The web portal for checking status and traffic needs improvements."
"The solution needs additional product options for small and medium enterprises."
"The solution needs additional product options for small and medium enterprises."
"The reports provided don’t give detailed information about DDoS mitigations, bandwidth utilization, etc."
"In bot management, there are times when attackers find ways to bypass Akamai, which is a continuously evolving challenge."
 

Pricing and Cost Advice

"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."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The price of the solution is expensive."
"The cost primarily depends on the size of the organization."
"A free version of the solution is available."
"We are using the free tier of the solution."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"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."
"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 pricing is a pay-as-you-go model that is charged by the hour."
