Herb Angle

Owner at Hga consulting

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.

Offers Application Protection Against Web Attacks

There is a need for expanded licensing terms and options. There's also a need for improved and more agile customization features. The user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

"F5 Silverline offers load balancing, flexibility, and reliability."

"The most valuable feature is flexibility."

"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."

"The most valuable feature of F5 Silverline Managed Services is it becomes similar to a distributed architecture."

More F5 Silverline Managed Services pros

"Since we are using this tool for protection purposes we really appreciate the hybrid security abilities; the main idea here is that we powerful protection our application needs."

Cons

"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."

"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."

"There are some issues with the CDN services."

"The pricing could be improved."

"Cloudflare could be improved by introducing a mid-tier pricing option."

"The product support needs to be accessible from more places, a wider area of coverage."

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."

"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."

More Cloudflare cons

"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."

"I just hope the price can be cheaper."

"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 user needs to be able to manage each policy as required; the functionality needs to empower the user. There should be a complete suite of desktop provider policies available to users. Overall, it needs to be more user-friendly."

Pricing and Cost Advice

"I believe their performance has improved, but I'd like to refrain from discussing the pricing aspect related to the cloud. The pricing, in my opinion, could be simplified, and I think they should consider reevaluating the pricing for support, as it can be quite high. At times, this cost can make it challenging to choose CARFAGuard or opt for the support."

"The price of the solution is expensive."

"The product's pricing is cheap."

"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."

"So far I use free tier and happy with it. You can subscribe to business package if needed."

"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."

"There are no additional costs beyond the standard licensing fees."

"We don't have any issues with the price."

More Cloudflare pricing and cost advice

"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 price of F5 Silverline Managed Services could be reduced."

"The product’s pricing is reasonable."
