M.A. Faisal - PeerSpot reviewer
General Manager at bKash Limited
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.

Robust protection has secured global web assets and keeps critical applications available
F5 Silverline Managed Services can be improved in areas with complex onboarding processes and slow deployment settings. Tuning of policy requires significant technical expertise, and there is a lack of knowledge in the F5 world where one needs to go through a steep learning curve in understanding what and how the policy should be configured for effectively protecting an application. These processes need to be streamlined.Knowing the limitations of F5 Silverline Managed Services, F5 has come out with a new product called F5 distributed cloud WAF platform, which has a better API integrated with security modules. It also offers advanced auto discovery, swagger, and open API validation, which is much better than Silverline.
