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.

Offers robust analytics and seamless cloud integration with minor room for user interface improvement

The Microsoft support and the analytics are what I appreciate about Azure Web Application Firewall. It integrates effectively with things such as Sentinel and Defender for Cloud, so mostly it's the analytics and now the AI capabilities that have been introduced with Co-pilot. It helps when looking for threats. It reduces issues significantly because the filtering capabilities are high. Given that it's a cloud solution, we have very minimal downtime, especially because we have Microsoft support. On a scale of one to 10, I would give it an eight.

Optimized ecommerce performance and improved access control through image handling and IP filtering

I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

More Fastly pros

Cons

"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."

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

"Their documentation could be better. They don't have documentation that explains everything well."

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

"The reporting could be more granular."

"The blocked logs are difficult to read at times."

"The ModSecurity core rules need to be updated."

More Cloudflare Web Application Firewall cons

"From a reporting perspective, they could do more there."

"I would say that Azure's customer service is not that good...I am not very happy with the support offered."

"I encountered difficulties with certificates for a Linux server when implementing protection. I had to create the entire chain, as I couldn't simply upload the certificate and the chain."

"In Brazil, we have some problems with the phone service that affect our connection with the cloud. However, it isn't common."

"There is a need to be able to configure the solution more."

"The pricing needs improvement, and I think for beginners it will be a little bit complicated, so the ease of use could be enhanced."

"The support for proxy forwarding could improve."

More Azure Web Application Firewall cons

"The solution's pricing could be better."

"Fastly's customer service area needs improvement."

"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."

"The product should provide improved bot detection and management."

"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."

"It's not easy to start with Fastly if you don't have VCL knowledge, so it appears very complex at the beginning."

"What I don't like about Fastly is that they charge a heavy price."

"Support is not that great."

More Fastly cons

Pricing and Cost Advice

"It is not too pricey."

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

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

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

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

"The annual licensing fee is $10,000 USD."

"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."

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

More Cloudflare Web Application Firewall pricing and cost advice

"Azure WAF has price advantages over other WAF solutions. The pricing model is flexible because you pay on a scale based on the level of protection you need."

"The price is for this solution is fair and there is a license needed."

"I give the pricing a nine out of ten."

"The price of the solution depends on your architecture and how you manage it. You can control the cost in Azure quite well. The costs do not directly correlate to expenses in the features we are using."

"The price is reasonable. It is approximately $2,000 US per month."

"We have an enterprise agreement with Microsoft and the pricing is good."

"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."
