Advanced security reporting has protected high-traffic betting platforms from constant attacks

I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Application security has protected critical banking services while policy learning minimizes false blocks

F5 Advanced WAF performs well overall, but I have noticed some points that could enhance the solution. Initially, policy tuning could be simpler, as while the learning engine is powerful, initial tuning still requires experienced engineers, which can be challenging for new teams due to the complexity of options and parameters. A more guided and simple tuning workflow would help reduce the learning curve. Additionally, tighter native integration with SIEM or SOAR tools would simplify correlation and investigations for security teams, although log exports are available. Overall, these are not blockers, merely enhancement opportunities, and once tuned, F5 Advanced WAF is very stable and reliable; improving usability, reporting, and onboarding would make it even more effective for larger environments.

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:

Pros

"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."

"The product has a valuable security control functionality."

"I'm highly satisfied. It's remarkably user-friendly, enabling me to quickly identify issues, and deploy solutions, and it offers the necessary features."

"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."

"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."

"There is a huge signature repository"

"The rate limiting features and customizations in terms of URL match and applying policies are valuable to me."

"It is configurable via API."

More Cloudflare Web Application Firewall pros

"iRules are quite appealing when it comes to F5."

"The solution uses AI to protect against botnet attacks."

"The web application firewall itself is most valuable. It provides positive security and negative security. In negative security, it blocks a task such as cross-site scripting, code injection, etc. In positive security, it lets you specify and enforce things, such as the parameters allowed in username and password fields and the number of characters allowed in a field."

"Overall, F5 Advanced WAF is a strong, dependable enterprise solution that works best when seen as a long-term security platform rather than a quick add-on; once properly designed, sized, and tuned, it runs quietly in the background and effectively does its job without constant attention."

"It's flexible and powerful, and the users can input their own rules to the system."

"The solution's most valuable features include application DDoS protection, bot blocking, and HTTP header verifications."

"The initial setup was was easy to install."

"This solution is an enterprise-class firewall that provides both load-balancing and security."

More F5 Advanced WAF 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

"If they add logs history within the Cloudflare offering, that would be a great benefit."

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."

"Cloudflare Web Application Firewall should include port forwarding features."

"I have experienced some difficulties with Cloudflare's support as a customer based in India."

"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."

"The product can improve by having more multitenancy capability, which is currently not available."

"Support can be challenging at times."

"The ModSecurity core rules need to be updated."

More Cloudflare Web Application Firewall cons

"They could provide better pricing."

"Nevertheless, F5 products are generally considered to be hard to deploy."

"There is a gap in report management."

"I would like to see the API Protection improved."

"I would not expect traffic details to pass through the web application firewall across the length of the whole application. I think that there is a web application where it can let the application function without traffic going in into the WAF."

"One area for improvement in the product is its SSO integration, which posed challenges and required significant effort to resolve."

"There should be more ability to rate limit certain scenarios. The majority of the time, it is either on or off. For certain types of use cases, there should be the ability to rate limit, not just enable or disable."

"The solution should include protection against web page attacks like what is available in FortiWeb."

More F5 Advanced WAF cons

"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."

Pricing and Cost Advice

"The solution's pricing option needs to be more transparent for enterprise clients."

"It starts at $20 and can easily go up to $200 monthly"

"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."

"It is not too pricey."

"We pay $210 per month for CloudFlare WAF."

"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."

"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."

"The solution is expensive."

More Cloudflare Web Application Firewall pricing and cost advice

"A yearly license for F5 Advanced WAF is expensive."

"F5 Advanced WAF pricing structure should be adjusted to meet the need of small to medium-sized companies."

"The price of F5 Advanced WAF could improve it is expensive."

"The pricing is too high."

"The price of the solution is reasonable when compared with other products, such as FortiWeb. I am very satisfied with the price."
