Has helped manage client domains with streamlined access control and threat visibility
I don't know what areas could be improved with Cloudflare WAF; Cloudflare is constantly improving and adding features to their feature set. They're doing a good job, and as far as DNS and support for any domains that I create or my clients create, it's mandatory for me to make sure that they have Cloudflare as their DNS provider. 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. It doesn't pay to try to host your own website.

Manages network threats and supports application control with ease
The best advantage of F5 Silverline Managed Services is that it is easy to use. The admin guide they provide is easy to understand and allows for implementation within a few days. The traffic manager and the monitoring tool are valuable as well. The monitoring tab displays GET and POST requests in a readable format, making it accessible even to non-tech-savvy individuals. It offers effective reports and monitoring capabilities.

Manages SSL load balancing and offload efficiently while providing excellent support
The most valuable feature is the support from the engineering team. They quickly resolved a VLAN issue that other vendors could not. The product allows us to manage multiple networks and VLANs into a single box and add numerous web services and farms efficiently. The SSL management and integration capabilities are also standout features.
