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

"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"Cloudflare is easier to manage than the solutions provided by these vendors, and the user experience is much more straightforward and appeals to a lot of developers."
"This solution has improved the security of our organization."
"Many websites require an SSL certificate because they sell stuff and want SSL. Cloudflare comes with an SSL certificate built in. It's automatic. You sign yourself up for Cloudflare, and an SSL certificate automatically protects your website. You don't necessarily need a certificate if you have a connection between your website and your host, the server, Cloudflare, and the host."
"The solution provides good load balancing and protection against DDoS attacks."
"So far I use free tier and happy with it."
"The initial setup is very straightforward."
"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."
"The initial setup is straightforward."
"If you are looking for web security and don't have any solution, just try it."
"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 takes fewer resources to operate."
"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."
"They've scrubbed DDoS traffic that was blasting us offline, thus allowing legitimate traffic through and letting our service return online."
"The support from Akamai is great, and they provide excellent information and mitigation services."
"The solution does not have hardware or maintenance requirements and is very easy to scale."
"Prolexic technical support is second to none."
"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."
 

Cons

"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."
"The product needs to improve its automation."
"The documentation could improve for Cloudflare DNS."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"Perhaps I would ask that they improve the Free plan and allow us to use it with any TLD (certain ones are not allowed)."
"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."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"Support response time could be improved."
"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 product could be improved on the global load and the integration with the other solution like Cisco and Dell. As a representor of the operation, we prefer to have one platform which can accommodate all type of integration. We are also looking for more improvements in the security policy configuration."
"The price is high in comparison to other products."
"The price of F5 Silverline Managed Services could be better, they are not very flexible."
"F5 Silverline Managed Services could be improved with more intuitive dashboards, a self-service option for respondents, localized support, and better pricing since I think it is high."
"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."
"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."
"The solution needs additional product options for small and medium enterprises."
"The web portal for checking status and traffic needs improvements."
"It's expensive, though."
"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

"We don't have any issues with the price."
"That is one of the great features. I was able to access the majority of the features and services for free."
"The product's pricing is cheap."
"The cost primarily depends on the size of the organization."
"The price of the solution is expensive."
"The tool is a premium product, so it is very expensive."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"The product's pricing is minimal compared to other products."
"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 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."
"The product’s pricing is reasonable."
"The pricing is a pay-as-you-go model that is charged by the hour."
