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.

Cloud applications have gained stronger protection and real-time defense against web attacks

What really stands out for me in terms of advantages of F5 Silverline Managed Services is that in a single cloud platform, I can protect my web applications against attacks. I can also use my load balancer in F5 because they are providing and acting as a load balancer too, and they will support the volumetric and DDoS attacks and malicious attacks. Regarding the real-time threat intelligence feature, I do use this aspect in F5 Silverline Managed Services. It blocks malicious IPs or bad IPs for my server, protecting against my applications. For example, if someone is a bad actor trying to access via a malicious IP, I can block it because the threat intelligence has the capability to block the malicious IP. The adaptable and flexible security impacts threat response time positively. It is effective because it blocks my malicious traffic. Whenever I face issues related to that application, it automatically routes my traffic to act as a proxy and routes my traffic to their scrubbing center, especially in case of any volumetric attack.

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.

Quotes from Members

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

Pros

"The security features are valuable. The particular feature we use is called OWASP."

"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."

"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."

"Cloudflare WAF provides protection through rules and functionalities like Cloudflare's SDRAP."

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

"The impact of Cloudflare Web Application Firewall's integration with existing web technologies on our site's performance and security measures is quite great, actually."

"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."

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

More Cloudflare Web Application Firewall pros

"The most important feature is that they have seven firewall protection, to protect our web servers."

"The product’s UI is easy to understand."

"The stability of the solution is very good."

"The initial setup is very straightforward."

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

"We have a lot of businesses that we put behind this solution, and it has really helped us in terms of monitoring the logs and incidents."

"The most valuable features are the configuration and configuring the process."

"The most valuable feature is flexibility."

More F5 Silverline Managed Services pros

"Rate limiting is a good feature that protects from volumetric attacks."

"Compute@Edge features are valuable to me."

"The product's initial setup phase is straightforward."

"Its initial setup process is straightforward."

"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."

More Fastly pros

Cons

"It would be ideal if the solution offered better log integration and more integration with different platforms."

"We have noticed some latency when the call goes through the firewall. That could be improved."

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

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."

"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."

"The platform's control features related to real-time authentication and response time need improvement."

"Cloudflare Web Application Firewall should improve visibility for a customer."

"The learning curve was steep initially."

More Cloudflare Web Application Firewall cons

"There is a lot of room for improvement with their tech support. I am not sure F5 Silverline Managed Services can be classified as having tech support."

"In terms of the scalability, this part is always so confusing because they are checking for packet count. Also, after an attack, they said that the throughput must be from gigabits but then I check my bandwidth and it is already done in gigabits. So it is a little bit confusing."

"F5 Silverline Managed Services can improve by reducing the price."

"We'd like more AI to be used. Right now, they don't use it enough."

"Sometimes tech support can be slow. They take more time assigning engineers to complex issues, however, they resolve the issues by joining me to fix them."

"The price is high in comparison to other products."

"There is room for improvement in the stability of the solution."

"The price of F5 Silverline Managed Services could be better."

More F5 Silverline Managed Services cons

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

"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."

"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."

"The solution's pricing could be better."

"Fastly's customer service area needs improvement."

"Support is not that great."

"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."

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

Pricing and Cost Advice

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

"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."

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

"It is not too pricey."

"The solution is expensive."

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

"Cloudflare Web Application Firewall is more affordable than other solutions."

More Cloudflare Web Application Firewall pricing and cost advice

"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."

"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 product’s pricing is reasonable."

"It is an expensive solution."

"Fastly is less expensive than one of its competitors."

"You need to pay a premium price for the tool."

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

"The pricing has been very competitive."

"The solution is cheaper than other products in the market."

"In my opinion, Fastly is priced competitively."
