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

"It's very user-friendly."
"Cloudflare offers CDN and DDoS protection. We have the front end, API, and database in how you structure applications."
"For businesses that don't have a dedicated security team, I think it's a better product; it's more intuitive for people like us."
"Because our website is blazing fast it improves our conversion rates."
"CloudFlare has positively improved my site's speed, performance and security."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"We're using dynamic components to build flexible pages to create and manage Git merge requests for code and reviews."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"This is a good product that you can rely on."
"F5 Silverline Managed Services is recognized as one of the best solutions in Gartner for WAF; I believe it can effectively manage vast amounts of traffic better than other brands like Citrix or FortiGate's WAF solution."
"The most valuable feature is flexibility."
"Overall, this is a good security solution, but there is no such thing as a perfect appliance in IT."
"F5 technical support is really good; it is better than A10."
"The stability of the solution is very good."
"F5 Silverline Managed Services has a very positive impact on my organization."
"Prolexic technical support is second to none."
"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."
"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."
 

Cons

"The Cloudflare load balancing capability hasn't really helped in enhancing my website's uptime and resiliency because we don't really get that much traffic; it's mostly remote users, and web hosting is done by a web hosting service."
"The solution could work at being less expensive. It costs a lot to use it."
"With CDN loads, sometimes we get an error that the host server is unavailable when the connection between CloudFlare and the server timed out."
"There are some issues with the CDN services."
"More insight into analytics and threats would be a good place to start improving Cloudflare."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"At the end, it is worth than giving your house keys to the NSA."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"The navigation is difficult to use."
"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."
"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 negative aspect is that the product is expensive."
"We'd like more AI to be used. Right now, they don't use it enough."
"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."
"F5 Silverline Managed Services can improve by reducing the price."
"To make this solution much better, they must have a user-friendly configuration interface."
"The solution needs additional product options for small and medium enterprises."
"It's expensive, though."
"In bot management, there are times when attackers find ways to bypass Akamai, which is a continuously evolving challenge."
"The web portal for checking status and traffic needs improvements."
"The reports provided don’t give detailed information about DDoS mitigations, bandwidth utilization, etc."
 

Pricing and Cost Advice

"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."
"There are no additional costs beyond the standard licensing fees."
"The product's pricing is cheap."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"We don't have any issues with the price."
"We are using the free tier of the solution."
"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."
"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 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 pricing is a pay-as-you-go model that is charged by the hour."
