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 provides an answer to a variety of issues, so it gives you very high value for your money."
"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."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The initial setup is extremely easy but will require access to your Domain Name Servers."
"Cloudflare DNS is widely used, and it's good for websites. If we use Cloudflare DNS and update one record, it updates in their office instantly."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"It's a reasonably priced solution that meets customers' needs and it's not too difficult to deploy."
"DDoS protection is this product’s most valuable feature."
"The product’s UI is easy to understand."
"Most vendors fulfill the requirements for standard DDoS protection, but F5 Silverline Managed Services has a better understanding of defending web applications like HTTP and can mitigate more bot activity than any other vendor."
"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 very 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 most valuable features are the configuration and configuring the process."
"F5 Silverline offers load balancing, flexibility, and reliability."
"Prolexic technical support is second to none."
"The solution does not have hardware or maintenance requirements and is very easy to scale."
"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."
"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

"There might be helpful if there was some web application firewall feature."
"One area of improvement is in the Access Rules. Hypothetically, if we wanted to block or challenge traffic outside of the United States, the only way to currently do that (as far as I know) is to enter every single country outside of the United States."
"More insight into analytics and threats would be a good place to start improving Cloudflare."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"If they improve on the placement of their data centers, it would be better. I'm living in a remote area. I would like to connect to them without any kind of lag."
"Latencies are always a problem."
"The product needs to improve its automation."
"The price of F5 Silverline Managed Services could be better."
"Improvements could include the creation of highly optimized profiles, optimization deployments, and compression profiles for better performance."
"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 navigation is difficult to use."
"F5 Silverline Managed Services can improve by reducing the price."
"I just hope the price can be cheaper."
"There is room for improvement in the stability of the solution."
"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 web portal for checking status and traffic needs improvements."
"The solution needs additional product options for small and medium enterprises."
"In bot management, there are times when attackers find ways to bypass Akamai, which is a continuously evolving challenge."
"It's expensive, though."
"The reports provided don’t give detailed information about DDoS mitigations, bandwidth utilization, etc."
 

Pricing and Cost Advice

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"I give the price a five out of ten."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"A free version of the solution is available."
"The product's pricing is cheap."
"We are using the free tier of the solution."
"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."
"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 product’s pricing is reasonable."
"The price of F5 Silverline Managed Services could be reduced."
"The pricing is a pay-as-you-go model that is charged by the hour."
