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.

Load balancing has improved traffic distribution and currently supports high availability upgrades

F5 BIG-IP Local Traffic Manager (LTM) offers effective load balancing methods that help distribute traffic across our servers, whether we have two or several. This load balancing feature stands out as it is the fundamental work we do with F5 BIG-IP Local Traffic Manager (LTM). While I recognize there are many features, such as iRules, which I have not explored yet, we primarily work on VIPs, pool members, and traffic distribution. The load balancing algorithms' flexibility makes them very useful for our team, enabling us to choose different servers and manage load effectively. We use various methods based on user or application requirements, making the algorithms set up by F5 in the backend quite helpful. F5 BIG-IP Local Traffic Manager (LTM) positively impacts our organization primarily through its load balancing capabilities. We avoid traffic overload on individual servers by placing backend servers behind F5 BIG-IP Local Traffic Manager (LTM) VIP. This load balancing helps us manage traffic effectively. Since the configuration of the I-series, we have had smooth performance, and with the recent migration to the R-series, it is working faster than before, providing positive outcomes for our operations. Since moving to the R-series, I notice improved performance; it is user-friendly and handles traffic efficiently. The upgrading process is different as we create tenants and a main host. R-series has better CPU and memory, leading to higher throughput with minimal downtime, making it a significant improvement over the I-series.

Cons

"The learning curve was steep initially."

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

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

"Its stability could be better."

"The dashboard could be more user-friendly."

"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."

"They have some limitations with third-party integrations."

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

More Cloudflare Web Application Firewall cons

"The tool must be simplified."

"Scaling up is complex. It's expensive."

"There are some aspects of F5 BIG-IP that could be improved, the main one being virtual machine support. We have seen that even with the virtual editions, there are some things that we would like to do that are currently not possible with virtual machines."

"F5 BIG-IP LTM can improve on the SSL loading which includes the authentication of certificates."

"It is a hardware load balancer, and its installation procedure is more complex than a software load balancer."

"Cloud native integration should be provided."

"Not everything is intuitive."

"While the licensing is good through the AWS Marketplace, it is more expensive than what you could buy yourself."

"More training should be available to customers."

Pricing and Cost Advice

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

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

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

"The solution is expensive."

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

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

More Cloudflare Web Application Firewall pricing and cost advice

"The tool is cheap."

"Check other vendors like Cisco, Citrix or A10 Networks. There are plenty in the market with which you can achieve same thing."

"BIG-IP LTM isn't a cheap solution - I'd rate its pricing as three out of five."

"It could be priced a little less, especially on the virtual side. It gets a bit expensive, but you get what you pay."

"It is the best solution, but that comes with an increased price."

"The price is high."

"The pricing is inclusive of many features."

"Security should be involved in any base license. When you bring on F5, you only have default license. Then, the ASM product license has to be purchased. It would be great if F5 could include the ASM in the base license."

"Take a look at the modules that you are going to use. Look into the best bundles for them."
